Watch NASA land the Perseverance Rover on Mars!

[Music] so [Music] [Music] [Music] [Music] [Music] [Music] [Music] [Music] [Music] [Applause] [Music] [Applause] [Music] [Applause] [Music] [Applause] so [Applause] [Music] [Music] [Applause] [Music] hi it's me tim dodd the everyday astronaut welcome to probably one of the biggest events of the year in space flight uh there is a mars rover heading to mars currently at let's see uh 11 500 miles an hour so about 18 000 kilometers an hour so just screaming to mars there's no turning back um let me before we get started with anything let me apologize um i'm still in south texas and if you know anything about uh what's been happening in texas we've been kind of without power for uh the better part of the week kind of on and off and trying to find power where available there's uh i can't promise you that i will have power this whole set and in which case this is a very uh temporary space so i apologize if there's any issues um i'm sorry if there's anything um you know if audio goes down or anything goes down just straight up i'm sorry we've done everything we absolutely can to try to be able to stream this for you today uh we have not had water and electricity so we're just trying our best here um so i appreciate if there's any uh any extra grace that you guys can give me today um would be fantastic so uh it's been a very long week let me tell you that um we are still working on building out mars studio b but in the meantime let's go ahead and get you guys we're not we don't have a pre-launch preview because this thing launched last july on an atlas 5. so now we have a mars rover heading to mars like i said just screaming towards mars but if you do want to learn a little bit more about this particular mission um you can go to everydayastronaut.com and you can click on we do have an article already kind of writing up almost everything you can check out our our timeline here of events that we're expecting to see so we do have those down in the bottom that we will be highlighting they'll be a lot more visible once we highlight them as you can see and uh so we'll be listening along with nasa and and hearing all the callouts and i will be providing the live stream for that as well so this is going to be insane so just a friendly reminder of what's happening here nasa in last like i said last july launched the perseverance mars rover for the mars 2020 mission and um and now it is after a seven month transit to mars it is finally arriving and it's really exciting obviously for those of you that remember curiosity mission or you know the insight or some of the other mars missions you know there's no turning back they can't pause and say wait stuff doesn't look right they are flying at mars atmosphere like i said at about 18 000 kilometers an hour right now so i'm actually going to increase their mission audio so that we can listen in a little bit here uh meanwhile there's another fun thing we can kind of look at here this is a kind of pre-landing simulation that nasa provides us so we can take a look at um the the current distance it's it's screaming right now um hey that can't be right it says it's 500 miles from the landing site no that's not right it would get there in zero time or is that what yeah it's not that's not that's not true what um but i just wanted to say um okay station 63 turn transmitter drive off one nine three five zero two oh i'm not live on the thing that's probably why where's the live stream thank you discord thank you guys i appreciate that there we go that looks more correct um yeah so that sounds about right ten thousand five hundred kilometers so about or thousand miles uh so that's about sixteen thousand seventeen thousand uh kilometers away so it is like i said just absolutely screaming um at everything so i first off hi discord thanks for saving my butt already uh you guys are amazing thanks for tuning in with me today even though like i said this could be a little bit dicey but yeah we are about an hour and 18 minutes away from entry uh and landing and everything so the sequence of events is about seven minutes of terror uh they they basically will stop actually most things are based on the time but then after a certain after about five minutes it kind of doesn't matter the time it's all relative to uh the elevation and velocity and at that point um perseverance will basically just be focusing on those things so not the activity all right let's let's get through a couple of your guys's um there's a bunch of new members i really appreciate you guys um luis and wesley and scott you guys are amazing um good luck percy from the martian engineer and let's see this is really cool to hear from thomas because don't forget they actually put um like a million names or something pretty nice of nasa to send my name to mars oh and a cool rover and helicopter too thanks for making space so exciting honestly i don't know what i'm more excited about um between the actual rover or the um ingenuity helicopter so don't forget there's literally like a little um a little tiny drone that's going to it's mounted to the belly of this rover and as soon as they land they're going to drop that rover that little uh drone down it's only got two propellers that counter rotate well come on they're huge uh they're not really they're actually rotors sorry they're not technically propellers they're large rotors uh i believe they're about a meter in span uh so about so the thing's about three feet instead and um in span so um yeah it's awesome yes i can reduce nasa's audio a little bit here for you guys sorry um yeah so um currently studio b is not set up for those you asking nope it has no power and needs a lot of work before it is a studio b um so when studio b is up it'll be a big deal um but that is something that i have oh hang in about 30 minutes again flight this fp go fp i can confirm via eha that the four expected s p monitors are now response disabled as expected just kind of listening copy all protection oh i can actually switch to kilometers ooh i'm gonna do that yes oh there we go that's what i wanted okay so i'll keep answering some of you guys questions here uh we're going to keep this up and for those who are curious what we're looking at right now as it's as it like basically what this atlas 5 rocket um inside of the fairing of the rocket was this and this is basically the cruise stage with the aeroshell with the heat shield with the um with the rover stuck inside so um so that's what we're seeing here this is a little 3d render of it and oh look i can even float around that's super cool okay so so the cruise stage here oh this is awesome why didn't i play around with this before so the crew stage obviously as you can tell has solar panels um that's to keep the the vehicle powered up on mars um the vehicle once it's on mars will use a rtg a radiothermal nuclear generator um but so the crew stage is just attached to this aeroshell or the back shell here it called and then on the the dark side right here in the shadow is a heat shield a very large heat shield all of this was tucked inside of the atlas v um now currently um they're going to be doing a d they're uh they're going to despin the vehicle because they keep it spin stabilized um they will de-spin it using some small cold gas thrusters um and or monoprop thrusters and i'm going to listen in real quick here oh his audio is cutting out um so what's gonna happen though is in about an hour they're gonna de-spin and then soon after that they're going to detach the crew stage um fly with the aeroshell uh and enter kind of like an apollo capsule or something that you might be a little bit more familiar with some kind of more traditional spacecraft um listen in here real quick you see the dashed line that's where we expect if we had a perfect trajectory and at this point we're still pretty close you cannot see we're not ours is available telling where it is and the uncertain ellipses have been nicely collapsing we're actually pretty close epu three we put on port so that looks good so then to continue uh what do i as we go uh into edl you see here at first we're actually still in outer space and then actually at one point this will be the top plot on your screen you'll see that we rapidly decelerate in the atmosphere and actually go to parachute deploy hopefully a trend and then we go further and we'll just zoom in on that a little bit so this just shows you more zoom in of that and we'll do that actually during the pdl so you can get a good look at all and you can see all the events that are gonna put dash lines because they're not quite certain at what time they're exactly but uh it should be closed sorry his audio is is pretty clunky i'm hearing that on my end here it's very clunky so i'll just keep talking here um so yeah people ask me why it spins they do it for a couple reasons sim um if you're spinning and if you're doing any kind of maneuver uh on your access where you're spinning you can null out say your engine was a little bit off thrust this isn't exactly why they do this but pretend you do have something spinning and if you're if your thrust was a little bit off access if you're spinning it cancels out that off off access bit 100 because it's kind of it's because it's spinning the thrust can just kind of cancel itself out and maintain going in the direction that they're intending to go now for this they do this for a few reasons to do a barbecue roll to make sure that the vehicle is cooled um it also does maintain stability because of its rotation but yeah so it's it's going to be um if i remember right there actually yeah they actually do a couple d spins um all right so this is an interesting question from mark saying uh which first this sample return or human landing because that's what's interesting about this vehicle uh perseverance has a core drilling uh system where it's going to be drilling into the surface of mars caching samples of mars in tubes and then storing them up underneath its belly it eventually it'll go probably like you know plant them somewhere in some kind of localized setting and then another vehicle in the future uh that could maybe return by 2030 is supposed to go and pick them up so nine years later pick up samples and we could maybe see samples back on earth in 2030. so the question is you know what which will happen first human landing or the sample return oh those uh i you know i there is a decent chance to me that the so i'm i'm team i kind of in the team of i think we might actually be landing on mars um by 2030 so the last launch window of the decade um which means that humans would probably get on mars while the sample return might be coming home which would be really really cool so um it'd be a win-win either way um when do every day what do everyday people get our turn to go to marx it's they're making progress you know right now the biggest concern and the biggest constraint is launch costs when you when this mission costs you know the atlas 5 that launched it was hundreds of millions of dollars the rover is a billion dollars basically um you know these are expensive bespoke missions and in the near future you know hopefully especially with the promises like vehicles such as starship uh as many of you guys are are probably very familiar with spacex the starship rocket is hoping to bring the costs down by orders of magnitude and what that means is um going to mars could be you know potentially just several million like five to ten to twenty million dollars um just for the the transportation so it could be you know if that's the case then all of a sudden that becomes you know if you sell if you can sell 100 200 tickets at once which i don't think you'll quite be doing i think it could happen in our lifetime um i personally i think 20 30 years from now we could see an average person that wanted to sell their house here on earth or give up on you know their earthly possessions and wanted to go work and live on mars that could actually be a possibility in my opinion in about 20 to 30 minutes now don't forget um friendly reminder here about the real time aspect of this so this um what we're seeing on screen is pre-simulated to limit it's pre-simulated so it's not the actual real-time data um that i have over here on a different screen so that's actually they aren't showing us the exact real-time data maybe there is one i forget um but there is a 20-minute delay so we're seeing it as in real time as physically possible by the speed of light so it's so as far as the crazy thing to think about is all everything we're seeing happened 20 minutes ago um so yeah it's it's it's pretty nuts um all right let me keep answering some questions for you guys uh musical wolves is a bigger heat shield needed for mars entry or is it more about how how to slow down with less atmosphere than slowing down causing overheating is this current starship trip like your mini apollo 13. um is this current starship trip like your mini so musical wolves first off hi and thank you um is a bigger heat shield so um heat shields are okay so this is an ablative heat shield which means they can handle really high peak temperatures but its total temperature um is is not necessarily as high as a more of a radiative cooled heat shield something like the silica tiles on the space shuttle now if you increase the surface area of the heat shield and you make it say twice as much surface area it can apply basically twice as much braking force and so there's this balance of of heat deceleration and all of these different forces and of course weight you know your mass of of your payload if you have a big heavy heat shield you don't want it to be any bigger than necessary now the thing to remember is this thing is coming in at interplanetary trajectories so it's it's absolutely screaming at mars atmosphere even though mars atmosphere is only about one percent as thick as actually i can tell right here by my shirt it is one percent as sick as mars atmosphere or as earth's atmosphere it's still very similar to when say when uh you know a vehicle's coming in and re-entering mars atmosphere uh or earth's atmosphere sorry you're in the upper atmosphere anyway you're aiming at that really really thin like the really really really thin parts of earth's atmosphere when you re-enter and when you're doing that because you're going so fast because you're going 10 times faster than a bullet that thin amount of atmosphere will still compress still heat up still slow you down so mars has the same exact physics you know there's nothing in the game of physics that's actually any different than what we're seeing happen on mars it's just it does take more atmosphere relatively speaking compared to earth's atmosphere so yeah hopefully that um hopefully that makes sense and helps answer that question um thank you very much sandra how's it going thanks for saying hi good to see you the martian engineer i was super lucky to interview the pilot of the ingenuity helicopter can't wait for it to fly that is super cool the martian engineer yeah seeing a having a little drone fly around on mars just even getting footage flying around uh perseverance think about how amazing that's going to be think about like the shots we could and hopefully see uh just to be able to get that sense of perspective that we would never see on mars before just to give you that sense of oh i'm there you know we're all familiar with drone footage now it'd be so so so cool um so yeah the the thing to remember with that helicopter is it can only fly for about two minutes before they need to land and recharge basically all day because don't forget mars although it obviously has you know a decent amount of uh sunlight it has about the same amount of sunlight per day as earth close relatively close um it's only about a quarter is powerful it's 25 percent the amount of sun energy is received by by mars or about 30 or whatever it is so it's um it receives a lot less solar so if you have a sm if you have say a solar panel here on earth um that would produce you know what we're used to we'll say i'm just going to make up numbers say 10 watts on mars that same solar panel only produced about 25 watts so um yeah to even be able to fly and recharge a solar panel for a little tiny martian drone is absolutely incredible um so um so um every other day astronaut in our discord wants to know if nasa could someday send um a rover to send an uh to go and retrieve old rovers um i don't i don't know if they'd ever go to try to retrieve old rovers um but yeah yeah aaron aaron in our in our discord says yeah maybe that would be the job of starship um i don't think it really makes too much sense to try to do any retrieval but one of the things to remember um one of the things to remember about um something like this is you know humans could go someday and visit them just like on apollo 12 when they visited the surveyor rover on on the moon they landed only like literally like 200 meters away from the surveyor spacecraft and uh it was just absolutely nuts to see a human walking up to a spacecraft that had been sitting on the surface of moon of the moon so um oh what did i say 10 watts oh sorry 10 watts on i'm totally sorry guys yeah sorry i've not been sleeping much 10 watts on mars or on earth would be only about 2.5 watts or or 3 watts on mars that's totally my bad i i apologize okay let's see here this is from cp scott thank you for your excitement about space flight i thoroughly enjoy your broadcast and uploads i can't wait to see spacex starship on mars that will be absolutely nuts that'll be nuts um let's see here um oz in our discord says um am i excited to see this a bad a process it's not actually the sabati a process being tested parts of the sabbati a process are being tested on mars there is this experiment called moxie which will be making oxygen on the surface of mars but it's not making methane um it's only you know in it's part of the the sabati a process is to take and do electrolysis um and then pull in co2 from the atmosphere and turn it into methane but this is only making oxygen on mars the moxie experiment so um yeah for those of you asking uh for if you want to join our discord channel consider becoming a patreon supporter uh by going to patreon.com everydayastronaut there you can get linked up to our awesome patreon community who asks lots of really good questions and helps me a lot with some of the live streaming stuff and they get a little bit of insight to all of the craziness that is my life at times so um so yeah thanks guys um so yeah if you want to help me do what i do and and get things better and hopefully i think studio b is going to need solar and batteries so that i never have to be without electricity for streams ever again uh consider becoming a patreon supporter patreon.com everydayastronaut that means the world to me so thank you guys for all of those that uh to help out um some extra grace thank you it's going to be necessary today again even just lack of sleep and lack of uh annoying i forget how hard it is to actually not have water and power uh we've been pretty lucky with power we've had about power half the time in the last week which is decent but one of the first nights is 26 degrees fahrenheit so like minus three degrees celsius or so um with no power was not fun yeah so all right let's keep going here thank you so much from um alexandra i really appreciate that um the best alpacas stay warm thanks for the stream i'm we're trying i probably should be wearing another layer uh but it's all right um thank you very much from sergey um tim the telescope is aiming in my ear where else would you want to point a telescope besides directly in my ear maybe we'll point it right like that it's a cute old nautica telescope i don't know i think it's really cool um uh corona kevin wants to know do we know how much the cruise stage weighs and also the final rover weight the rover is just over um over one ton basically so we've got the the specs on it here um yeah it weighs uh here's the the width length and height of curiosity and perseverance they're very similar so don't forget perseverance literally used some of the leftover hardware like backup hardware for curiosity so they are based on the exact same platform they're very similar rovers they both have a very similar rtg and similar wheels a similar system um yeah so let me see if i can find it here but we do have some of those information yeah the rope the wheels on curiosity did sustain a lot of damage um that's something that they upgraded a lot for this vehicle hang on i'm gonna listen here quick i'm gonna make sure one of these is muted yeah okay just prior to cruise stage separation due to the transition to direct to earth tones uh we can expect x-band tones only until we have telemetry lock with mro which will be about one minute prior to entry which means we will be tones only for about nine minutes before receiving telemetry questions are we starting to do everything right now where there is based on what's being delivered additionally for anyone who's monitoring the sub system well i think i have two things going live here right now i want to find the other one so we don't have it sounds like there's two different things on my computer but i don't know where the other one would uh i let's see again it's left ear and right ear is anyone else hearing that on the live official stream that it would be two separate audio streams yeah it's it's very strong right now so i'm pausing it to see maybe that's on nasa's end let me just mute this one so here uh let me show you guys here um i think they are actually talking over each other on the official stream uh nominally we expect to have uhf coverage uh through seven minutes yeah i just wanted to make sure i understood why um i don't see the pencil numbers anymore but we're doing every other one in the run out copy correct we're receiving uh ess for every other uh od solution uh so we're running all the esf esf's we're getting okay so unfortunately they are talking over each other on the nasa feed um so um yeah oops so we'll have to kind of try to listen in and hear over top of two voices occasionally uh but we're going to be uh i'll help try to you know i'm pretty used to hearing things in in multiple years i'll try and help decipher what they're talking about when they're talking about something important so um yeah go flight we have evrs indicating our telecom reconfig for expectation that's affirmative flight top three leave that up for another minute or two please welcome our last window has terminated as expected medial team in the war room we were getting comments that some of um people's masks so travis uh no there is actually nasa still does not broadcast any higher than 720 just period they are working on upgrading that though as we speak so that'll be very very good this is uh thank you very much from phil may the force be with you i think thank you elmar i think the force needs to be with uh nasa jpl and lockheed martin today because this you know this is this is the big one this is the one that a lot of us have been waiting for uh for years and years and years and years ever since curiosity has just been knocking it out of the park knowing that perseverance was around the corner has just been uh something really exciting so yeah i think we all um really want to be able to see something you know see like what we did for curiosity we see that this mission control room just light up an excitement knowing that they have confirmation that a touchdown um yeah it's going to be pretty epic so i really hope it happens and everything goes well so um oh that's awesome x team i'm glad that you're your teacher is letting you watch this in school this isn't important this is history this is we are definitely watching history in the making so just under half a minute we're going to go one way and lose telemetry briefly until the station locks up again i'm gonna do this for a little bit here just so we can see copy telecom that is per expectation with our transmitter off cool um so they're gonna be losing some telemetry briefly now don't forget everything that they're seeing uh is is basically they're seeing in real time but there's a delay in in reality because of uh time and space and the speed of light basically so uh because it's so far away uh it's you know it's what is it like 360 million kilometers uh it's traveled that far um at this point i believe it's only uh someone discord you guys remind me how far it is actually from earth right now um it's something around like 660 or 100 million kilometers distance right now and it just takes 20 minutes for the speed or 11 minute yeah one way community it takes 11 minutes for something to get back right now but the further away you are from mars the more so because you know we're on two different orbits so there's times where you can be opposite of the sun from mars and earth and so you're you're the speed of light you know just takes that long so your communication can be anywhere from 20 minutes round trip to 40 minutes round trip um it's currently at 200 million kilometers away so 120 miles 120 million miles away so that's very far it takes that long for the speed of light to get there so um thank you very much for uh my entertainment yeah i am i i don't honestly guys i'm gonna be perfectly uh transparent here i've had such a crazy last week or two really i've had the craziest year so far you know my car got absolutely destroyed and i still don't have my car back uh to having now been without power and working on trying to build out studio b and just dealing with all the starship stuff dealing with all these other things it's just been extremely overwhelming i haven't even processed this yet so i'm probably going to be processes processing this in real time um assistance 132 copy edl phase one okay go ahead i don't love that we're hearing two audio channels our tracking stations have all confirmed the results of the transmitter drive offs and in lock one way cdl strategic back on that gds flight flight at this time i'd like to disable the alarms before edl main so please disable all the alarm files copy that happy altitude thanks okay let's get through a few more guys questions here if we can i like to try to listen in here and let you guys know um let's see okay so this is an important one uh slow bird what which way is the pointy end though uh that is a very important distinction here with something like the the sky crane that we're going to see well we won't really necessarily see too much today guys we're mostly going to be seeing data and eventually they're going to be able to send video back because this is the first time they're going to fully record video through um entry descent and landing including audio and even send up um you know videos and stuff once it's down but it's going to be riding on this crazy sky crane thing which is basically um think of like a quadcopter drone with like four repellers but replace the propellers with a pair of thrusters and it's and it's basically just controlling itself like this and then it it lowers the um perseverance down on three nylon tethers which then get cut with pyrotechnic cutting devices um right when it touches down it flies away and um so the pointy end on this vehicle is really more of a roundy it's actually the pointy end and the flaming end are really in the same place on this vehicle and it's extremely vital that they are pointing up because if they're in both well the flaming ends need to be shooting down but they need to be at the top of the of the stack if especially when when perseverance is hung underneath it um if at any point the flaming end is below that would be very very bad so um oh man uh yeah so so this is going to be very complicated let's see this is uh arcadium um tim is almost halfway to ride to space don't don't forget to help him out team space patreon.com everybody asking well thank you very much arcadia uh it still scares the crap out of me like i said that was all kind of a joke for me was when i first put patreon up the top tier or like when i hit 10 000 patrons i said i'd go to space and i'm having to slowly accept the reality that that might actually be happening someday and i am terrified by that i don't actually really want to go to space yeah uh um this is from 26 dimensions made a video about how ingenuity helicopter works that's awesome because it is the counter rotating rotors and it's a really unique control system i've actually held in my hands we have disabled alarms and start a new rttp processing session choose copies okay i'm seeing some good questions so i'm going to try and get through them as quickly as i can but i've held those rotor blades and they literally had to warn me i was at jp and they had warned me um whatever you do like don't lift like just let us set these in your hands and stand still because you're you see this big thing and you expect to like have to like you know put you know put some effort behind it but they're so lightweight it it literally feels like they don't weigh anything because your brain sees this thing and just thinks it's going to be very heavy they are ridiculously lightweight like measured in just a couple grams or something it is so so cool um yeah so uh i i know how awesome and it takes that type of stuff all the time um gary mitchell thank you for main mode uh delivery of different we have the disabled protection position disarmed 77.7 are marking our slightly down from 148.1 meters of the previous copy okay guys so don't forget so it sounds like they're now into the actual um remaining telemetry they're basically getting into the final portion of the of the code of the software that's going into edl so you hear them say edl often that's entry descent and landing and that's going to be basically a whole code base a whole program the system will run once it knows and and hopefully is exactly right on where it is it will start this line of code basically and basically do all this stuff autonomously remember there's such a big delay in communications you know 20 minutes of like oh you should open your parachutes would obviously be way too late um let me hear your question are expected okay so they're basically transitioning to that here very soon so um thank you matthew guys i'm sorry that i'm gonna be missing some of your um some of your things here your super chats but i really appreciate it thank you very much for the new memberships to all you guys i you guys are awesome this is a good one from sumit says um primary mission find mark watney if it finds what they're gonna do he can't even offer him any food or water he's just gonna go up and give him a cold gentle hug with its mast in camera oh that's wait did nasa respond to my tweet hang on is that really what just happened i don't think i've ever had nasa respond toward wow well this is kind of cool guys check this out boom um where is it nasa responded to this tweet though that's awesome where'd it go where'd it go yeah rs2 talking about their hearts racing so that's very understandable um you know i said that my heart is already racing uh so that's really cool that's fun that nasa is watching or tuning in there so yeah that's that's super cool i've literally never had i don't think i've ever had the nasa official account wow cool oopsies i might have accidentally hit those when did i hit those i don't know okay i'm still listening in here um good luck percy from john i appreciate that for them um from edl approach mode which we entered about six days ago to the edl main spacecraft mode and this is really a fundamental shift in how we've operated the vehicle since it departed earth previously the spacecraft was programmed to maintain thermal control communication with the ground and stable power margins even if that meant interrupting programmed activities and dropping into a safe state with the transition to edl maine the spacecraft's number one priority is setting itself up for success on the journey down to the martian surface so as part of this mode change like activity mentioned we have gone ahead and disabled all system fault protection responses because we no longer need the spacecraft to stop and wait for intervention from the ground to recover in fact we need the exact opposite if at all possible we need the spacecraft to continue moving through the events of edl depending on what is largely a single string system with selective redundancy to do the best job it can so this is a good time to remind the team that success and lvdl is not guaranteed but we can be assured that you know a large part of our design was flight proven by msl so also as the activity mentioned we marked so for those of you wondering why we're only hearing audio on the right channel that's what nasa is actually giving us through here we do hear two different channels one on the left here one on the right i can make it mono for you guys if you want if that would help but it's almost more confusing than when you hear two voices in the same audio channel so yeah active at the time uh although many parts of the spacecraft are essential for edl the things that we marked healthy include the tds our landing radar both dimus and the vision compute element and the dmca we've also gone ahead and set the vehicle config in case uh we get a reset at the end of edl to make sure that when the vehicle i'm going to keep answering you guys questions here because they're kind of just going over on comms how they're in the main primary edl now so um i'm going to keep it in uh in stereo and if you guys need to mix down on mono on your end for your preferences then then that'll be for you guys to decide um okay so uh from rc teller pilot guy here nice to meet you on the dunes before oh the s9 launch yes will the sky crane be used for any scientific purposes other than just crashing away from perseverance mass tomorrow should be used for something so yeah you're right they so don't forget the sky crane literally um once it once it safely lowers the tethers and gets perseverance to the surface it flies away and crashes um it's not worth them trying to program or risk having it come anywhere or be anywhere near perseverance so the line of code is literally basically just yeet itself out of there they will literally just like turn on the engine full blast and get it as far away from over the rover as possible um it's not i think the safety issue is more like um i don't know it's better to put all of your mass all the mass of the scientific instruments onto the primary vehicle instead of onto the sky crane because okay so so what say now you have the sky crane and you land it somewhere softly and it has some scientific instruments why weren't those just on the rover right i think it's safer to put all of your eggs in one basket in this case um and then uh yeah i think that at that point uh you know you go and crash your your sky crane and that way you eliminate um yeah i don't know i don't think it really makes it's probably not worth it to try and do it um the other way so yeah they do quite literally stuff the thing full of uh of all the instrumentations on the rover and get the sky crane away from it as quickly as possible so um and the one thing is when it crashes though insight will be listening for the crash insight has a really sensitive seismometer um that's that's on the surface of mars right now they're going to see if they can pick up the actual touchdown and or the crashing of the sky crane because yeah don't forget the sky crane will crash so that's going to be super nuts if they if insight actually picks it up a lot of people are asking about live streaming and the capabilities of video there's just simply not enough um there's not enough bandwidth to be able to do anything like that unfortunately there's only small portions of a day uh during the day when they can do uh high high data bandwidth um and high data uploads back to earth so the again there's the difference between latency and your actual amount of bandwidth the latency is always going to be basically anywhere between like 10 minutes and 20 minutes one way from earth back to mars it'll take always 20 to 10 to 20 minutes to get the data from mars to earth now whether or not you have a lot of actual bandwidth whether or not you can actually upload large files um you know a video file or not depends on where your what which um satellites are are in view of the rover so here's actually this is perfect timing i totally meant to do this um thanks nasa um these are some of the um the actual deep space listening satellites so right now they have m20 pointed um which is one of the largest deep space satellites listening in for all these um all the the data right now but then once it's it on mars there's actually um a couple orbiters that it can relay data through for higher speed those slowest versions are like um pointing it straight at earth if it's in line of sight of earth you know depending on where it's at in the in the day um they can directly uplink to earth it's a little bit lower bandwidth or they can use more of an omnidirectional antenna so um but yeah exactly and in discord they're pointing out um alicat says that uh you know there's no starlink around mars yet but that could absolutely be a thing mars could have starling satellites it would only take a small constellation because because latency isn't a big deal on mars we don't care how long it takes we just care about you know bandwidth increasing bandwidth five or ten starling satellites would be game changing on mars and i would love for um i would absolutely love for elon to basically be like hey we're gonna send a falcon heavy with five starling satellites and get them in orbit around mars uh i'll donate those basically or something like that um i will donate those as in goodwill or something you know i think that'd be super cool so and um and they're doing a little time it hasn't been easy right i'm not even sure we've even been in all in the same room at the same time i mean i'm staring at folks across the uh across the internet as well even now right only yeah voice check okay um i do want to just extend uh my heartfelt appreciation from the edl team to the uh to the launch cruise team uh you've done everything we've asked for right i mean you've battled anomalies you've you know dealt with cesius you've done everything uh you delivered a healthy spacecraft uh to the place that we want to go and she's right on target right we did the last maneuver literally two months ago right this is pretty incredible in my opinion um and she's on with the right information to help us land you know doing the parameter update last night we're ready to roll you've done everything right um and you've put up with us too right you've put up with our eccentricities and the things we like to do in edl land so i very much appreciate that so you all should sleep in on friday since uh i you know you guys have earned it thanks for literally and figuratively putting us in the right position to succeed and uh let's land on mars together copy edl phase and as flight director i also would like to thank the whole team cruise ops edl ops edl team and the surface office as well it's been an amazing journey i think we all know that and it's been my honor and pleasure to work with you all side by side and your tireless efforts and endurance in the face of our challenges has been truly truly inspiring so kudos to you mission would you like to see something yeah just echoing the same words that uh that al and magdy have uh have mentioned you guys have overcome great obstacles in the last six and a half months and it started with an earthquake in this room on launch day at l minus 20 minutes so i can't be more proud than all of the achievements that you guys have have pulled off in the last six and a half months whatever happens in the next hour and a half you can be proud of the achievements that you've accomplished so far i look forward to seeing you on the other side and i only wish that the rest of our team could be sharing this moment with us this is a very unusual event this room is only as half as full as it would be if we weren't in this pandemic so missing everybody on the team who's not with us here today and go edl welcome to the eel family that's awesome back on that with that godspeed perseverance godspeed perseverance that is go ahead awesome continue the report sure thing we've since completed the edl start anchor as i was mentioning we changed our cbm row to edl reserve two-way non-coherent that row reinforces our cbm windows disabled keeps our packetization on it turns off our ranging and just to the auxiliary oscillator we've also started our real-time data products and reinforced medley on at this time we our next anchor will be at 12 30 local time all right so we're there we're just waiting now guys this is this is getting close t-minus basically 37 minutes in real life again and if if you could ignore the speed of light in 27 minutes from right now-ish uh this baby is going to be hopefully resting softly on the surface of mars oh okay now it starts it's starting to get real it's starting to get i'm starting to feel it now and the weight of this is actually getting yeah kitten to me now so um this is a really good question from um will gage says do we know perseverance's intercept periapsis i don't actually remember off the top of my head 55 or 60 kilometers or something is off the top of my head but i cannot remember so that's basically like saying so say you have mars here and you're going to be flying by it at you know kind of as close as possible but not too close obviously you don't want to hit the ground but you also don't want to be too low in altitude because you'll end up experiencing too much peak heating so this is there's this right little window um there's this right little window of altitude where you're going to bleed off the right you know there's there's this little window where you have to land in order to bleed off the right amount of velocity to slow down to do all your things and land on target i don't actually remember the exact um 70 kilometers i'm seeing in chat it might be 70 kilometers i it's been a while since i think it was like seven months ago that i remember seeing that but um yeah um it's a someone says 100 kilometers but yeah you do have to aim at a very specific section of atmosphere to to really for all the orbital mechanics to work out where you're getting slowed down and so for a brief moment your your vehicle is kind of in you know it would be kind of in orbit so say it didn't go in enough or for some reason it didn't keep slowing down which it would because it's continually decelerating because it's getting into lower and lower atmosphere but you they have to calculate this all out perfectly and it's going to be um yeah so it's just amazing that they can nail it with that kind of accuracy from this far away all right this is from um flight coach considered applying for the esa call for astronauts not doing that less time to watch tim todd keep it up with you since i had like 5 000 subs holy cow flight coach you are oh gee that is amazing thank you for for being around but i i don't think that's a very good excuse i think if you want if you have any inclination to be an astronaut i think you should absolutely become an astronaut i think you should why not you know what's the worst thing that could happen is all of a sudden one day you're living and working in space i mean that's pretty amazing so i'd say you should do that flight coach because we're all cheering for you we need some good good uh astronaut candidates out there there are some really good astronaut candidates don't get me wrong but you know never hurts to have more um harsha says sounds sounds for mars is cool and all but we ever know what mars smells like that's actually an interesting question because a human can't just like walk out on mars and smell it because obviously you would die it's it's mostly uh it's really cold um it's it's um it's pressure you know the atmospheric pressure is only about one percent you obviously don't have any breathable oxygen so it would be really really really bad um so you can't just go outside and smell it you obviously anytime you walk around on mars you'd have to put on a spacesuit uh you go through a pressure chamber you know between your habitat and actual um pressure lock why am i i am wow it's one of those days for me guys i am sorry uh but yeah you have to go outside uh while you're in your pressure suit and so you obviously you're basically when you're in a pressure so you're basically inside of a a separate little space station especially you're inside your own little like miniature space station you're not really i mean yes you're walking around on mars but like there's still always something between you and mars which is really interesting to think about airlock thank you gosh i am sorry guys i'm running on on very few uh bits of brain juice today i think uh but yeah hopefully guys i think in the next week i think we'll have power continually running and warmth and water that would be amazing and maybe i'll get some get back to normal myself um but yeah meanwhile um what do i think the chance of failure is so um balsh i actually talked this was back in the day for um the uh for insight lander um i spoke with some of the the heads of there and they actually said 50 50 chance uh for insight and those that was a team at lockheed martin and jpl um they said 50 50. it's never easy landing on mars is never easy okay probably the last time if you feel the need to do a battery change to do that before we go into quiet mode um also unless we have something updated we want to show in the next couple of minutes we're about to turn over our webex screen to telecom for tones at that point i'm happy to get updates in chat in our webex on edl ops but i'd prefer to not have any more call outs over the net unless you see something you do not expect it is super cool thank you very much from youngster gaming that is awesome um someone asked me well this is tap three i have um if you want to know this sim was at eyes.nasa.gov so eyes.nasa.gov or just search um yeah this one this one looks a lot better i almost like this better just to see this but um the the problem with this one is that it's not actually any real-time data but we'll keep this up because i think it looks better um yeah and i'm gonna listen to them real quick thank you very much to kp d world man appreciate that keep thinking they're gonna they like start talking then they go what's that and then it's good thank you top three thank you guys for saying hi um in discord arv wants to know um since since um the sky crane is a pressure fed system um does it use hypergolic fuels so it'll be simple in this case yes absolutely um it is a pressure fed engine so the engines on board are you know when they run on hypergolic fuels these are very storable fuels so they they don't need to worry about boil off and things they normally have to deal with with say a really cold liquid fueled rocket fuel like liquid methane or liquid hydrogen especially is really hard to keep pressurized and cold um here we go so oh hang on we're getting into something but hypergolic fuels are happy at even really really cold warm temperatures they kind of just don't really care they have a really wide uh range of where they operate as a liquid and what happens with hypergolic fuels is when they come in contact with each other um they instantly combust so that's what hypergolic means and it's um it means that when the two the two different the oxidizer and the propellant when they come in contact with each other they will instantly combust and have this really clean um really clean and simple ignition process now behind that those tanks are pressure fed and in order to keep those tanks pressure fed you actually do have a separate tank of helium so the helium tanks are higher pressure um when they need to uh basically as they drain hypergolic fuel out they need to backfill it with helium which is inert so it won't blow up it also is really sparse so you can you can and you can you can compress it really high and it won't weigh much and it can just help fill in um you know because of buoyancy it will fill in that gap in those tanks and force the hypergolic um propellant basically out so yeah i hope that um yeah let's see let me uh let me keep looking here um go plane at this time let's continue our briefing for the rest of the video sure so after coming out of edl start that's our last real reinforcement of the state that the vehicle was in throughout much of crews and edl approach and it's our precursor to making many more radical changes to the state of the vehicle matt wallace said it well the other day this is edl is kind of like a controlled disassembly of the vehicle as we go through we need to get rid of the things we don't need anymore and get ready to put our wheels on the ground so one of the final things that we're doing here is ensuring that our acs knowledge is a top notch we depend on acs to pass an estimate of the vehicle's attitude and rate of change to each starting point for propagating down to the ground when we come up in the edl prep anchor is when we'll take our the last state from acs and we'll be propagating from that point to the ground until we get more knowledge from the radar once we turn it on [Music] i can give a high level overview of some of the events that were that are going to transpire okay so i'm going to keep answering some of you guys questions because we've heard quite a bit of this this is a really good question from alice wade um is there a reason the spacecraft don't try to slow down in space before hitting the atmosphere to reduce stress on the heat shield parachute there's a very good reason and that's a fantastic question so in order to slow down without any other external force in space you know if you're in space there's there's no atmosphere there's and by the way uh sorry that mars looks like it has a big chunk taken out of it right now um looks like the simulation is a little bit broken here but um yeah so as far as um if you need to slow down in space if it is uh you know if there's no there's no atmosphere to push against there's nothing to slow you down you have to use propellant propellant weighs something so in order to slow down before you hit the atmosphere this is the same with reentering earth or anywhere else you have to carry that propellant so if your propellant if you have to take the propellant up there to slow you down before you you get to where you are um you have to have a much bigger rocket it's called the the basically the tyranny of the rocket equation so for every um especially you know interplanetary stuff for every one kilogram of weight so say for every one kilogram propellant that you send to mars requires about a hundred kilograms of weight on earth so it would take a substantially larger rocket to get something to mars if it needed fuel to slow down because don't forget it's going as we can see here velocity about 14 000 kilometers an hour so instead what's a lot lighter weight simpler and actually completely free basically is to let the atmosphere do the work let the atmosphere slow you down yes there's a lot of stress yes there's a lot of heat but those are forces that you can design around you can make um you know it's a lot lighter weight to design something to handle those those high temperatures does handle those high uh g loads relatively high g loads um likely i don't remember exactly what it is for this mission but peak g on re-entry for um for earth is like never really above like five g's um so it's not that high of design constraint when you're designing a vehicle to survive those forces um so yeah it's so it's pretty pretty important it's pretty important to remember that every every kilogram of mass going to anywhere really in space is vital so if you have to put a whole bunch of mass to have extra fuel to slow down uh your entire system is bigger heavier your rocket's more expensive and bigger um yeah so that's kind of why but that's a fantastic question um from noel could they use the helicopter to blow off the eventual collecting dust on the solar panels of the rover well no that's actually a great question but the perseverance rover does not have any solar panels only the actual the ingenuity helicopter has some solar panels but as far as solar panels on the rover it does not use that it uses what's called rtg so radioisotopic thermal nuclear generator so it's basically a little bit of decaying um what is it decaying what's macaulay um yeah it's uh and it's basically just creating a bunch of heat um someone remind me what's it it's decaying um plutonium thank you decaying plutonium and it produces a lot of heat and they can turn that heat into energy yeah it's a little man-made tree or human-made tree in a little box basically that takes uh that is going to be able to produce oxygen for the first time so um looks like uh yeah sorry if you guys refresh it looks like um i may have gone down for a second jason says um what is the engine out capability on the retrostage do all the engines need to work perfectly or can they lose an engine or two and still land softly good question so the actual sky crane vehicle has a pair that has eight engines and in four pairs of engines they can actually lose four of them and still continue this proper descent and do everything they need to do with just four of those engines so with half of them um yes i know this is is there a live telemetry in actual all right we'll get i'm going to try and debug mars here by refreshing it we've powered on our uhf but it's not yet transferring and the anchor has complete we expect our next anchor to start in two minutes okay i'm seeing if we have okay i'll turn their audio back up um let's see here is this live telemetry actually any better though i'm trying to see it it's lacking a lot of the information phase two taking a battery change so that's a good question how hard is it to guide a vehicle through heat shield aerobraking so as far as guidance it doesn't take much because it's actually passively stable when a vehicle has a blunt body like that normal heat shield it is passively stable so even if you lose all control it inherently will want to go heat shield first um so yeah that's on that and that's just kind of how that works but what you can do is you can still rotate and steer it a little bit and have your center of mass slightly outside of your main heat shield your center of mass can be slightly outside of your center of lift um and what you can do is you can actually literally rotate the capsule to help lift or or dive down deeper into the atmosphere um let's see i have to go back to kilometers again thank you flo i like this one this one looks a lot better than the other one the other one um although it might be legit real time data it doesn't have much and people are noticing that yes it is speeding up because it is literally falling towards mars right now dhrs vent anchor has begun here we are reinforcing the bcb discharge and charge states um that's a good question uh we don't you still have it why this hopefully it comes back sorry about that guys yeah i definitely need starlink down here i got starlink back in iowa now where i don't need it but i don't have starling down here yet hopefully that does not happen anymore i do apologize there's absolutely nothing i can do about it power is very intermittent here still in southern texas um we are we are on batteries and everything but um okay so they're making progress here i could go to a hot spot if we need to it might be a little bit more reliable we are powering off the cruise stage devices um the vehicle is preparing for the upcoming cruise stage operation in about three minutes or 15 seconds by powering off all the devices on the cruise stage in order to take me safe once the cruise page is jettisoned we are firing our first pyros to vent the hrs liquid and gas okay we're getting ready for them they're going to be separating the cruise stage here soon so after that it will not have the solar panels connected to it the ahrefs vent maker is complete we will see the next anchor in approximately three minutes we are currently 12 and a half minutes from entry interface we are coming up on cruise stage separation in two minutes and 20 seconds sweet okay two minutes 20 seconds from that cruise stage detaching from the aeroshell and the the heat shield of which the perseverance rover and the sky crane are tucked inside of right now so that's really good news they're right on track everything is perfectly uh they're aiming right exactly at the portion of the atmosphere they need to be aimed at so once this uh once the cruise stage separates um i mean it's pretty much going where it's going at this point there's nothing that's really going to change this trajectory or anything so i'm at this point it's just boop and we go so um oh man we're getting close this is crazy i'm sorry that i'm going to be missing a ton of you guys super chats but i i will try and get back to them as soon as they can let me make sure that this is this one appears to know you're switching telemetry will have stopped telecom is confirming that the spacecraft has switched to broadcasting tones these tones are received directly from perseverance but have very limited information content we won't receive real-time information until about 9-10 minutes from now once the mars reconnaissance orbiter starts relaying information from perseverance we are under a minute from cruise stage separation about 10 and a half minutes from entry interface yes oh that's awesome okay guys so yeah again we're waiting to hear that they have confirmation and again this has al in real life happened already but it takes 11 minutes for that signal to get back to earth today um just because of the rendezvous how far away mars is from earth at this exact moment so in real life it's happening to receive tones from perseverance coming standing by for cruise stage separation but the speed of light takes 11 minutes so rcs priming i don't know i mean this obviously is not real time video so let's crew stage sup we have indication that cruise stage separation has been confirmed by the spacecraft that's awesome so now we are t minus 10 minutes press advances landing software will wake up and begin the final preparations for entry the first action it will do is to fire warm-up pulses with entry thrusters these pulses ensure that the spacecraft gets the thrust that it wants during entry interface we're about nine minutes from entry interface that's awesome so yeah so like she said we're uh they're coming up on having it actually enter mars atmosphere and everything is looking absolutely bang on right now so this is very good news um once it hits the atmosphere it's basically going to be seven minutes uh again a fun reminder is everything that we're seeing now in real life the thing is actually in the atmosphere falling towards mars but again the delay of the actual speed of light to tell us that we got shadowed by the crew stage as it passed through our beam to the earth telecom indicated actually that we could see a signal that the cruise stage went between the perseverance engine capsule and earth so we saw a little blip uh the data stream stage separation you heard rcs warm-up that means that they are warming up the actual thrusters for the for the cruise stage uh or for so they're going to be de-spinning it now um using the reaction control thruster so that's rcs reaction control system and so they're going to get ready to be able to control it still through re-entry cruise two revolutions per minute down to zero and then we'll turn to its desired orientation from entry it will be separate the two bounce masks that have kept it balanced during all of cruise this will allow the entry capsule to have lift when it enters the atmosphere we have competition that has turned to the desire entry attitude we are about seven and a half minutes from entry interface sweet oh it's crazy to think that somebody is going to be humans doing this that is i mean i i don't know what i'll be doing then i will be honestly crying just and thinking about how scary that's going to be um let's see here i'm going to try i've missed a couple of you guys uh big super chats and i really apologize but i think for the next little bit i'm just going to be listening in guys we'll get to your super chats later uh so thank you for those of you watch carrier locks yeah sorry for those of you that have donated thank you so much um it means a lot right now especially just the past week uh but i'm gonna just listen in here guys and i'll help interpret whatever i'm hearing so you guys know what's going on flight level one we are continuing to wait for entry interface for about six minutes and 45 seconds from entry interface we have confirmation from greenback that they are receiving direct earth telemetry via that path the spacecraft perseverance is currently transmitting heartbeat tones these tones indicate that perseverance is operating normally and has nothing significant to report this is as expected we're currently just over six minutes from entry interface so yeah again guys we're hoping that everything is normal as we may say um and you know we're seeing that you know it's again 11 minute delay so it's coming up basically on the touchdown in real life so there's a there's a good chance that right now uh the sky crane is doing its job and it's lowering perseverance onto the surface as we speak if you could somehow forget the laws of physics and the 11 minute delay of the speed of light to get the signal back here to tell us that that happened that's what you would be seeing right now under uh about five and a half minutes from entry interface we're still receiving heartbeat tones we expect to continue receiving heartbeat tones until about five minutes after entry at that time perseverance will be no longer in view of our antennas here on earth about 90 seconds prior to entry the mars reconnaissance orbiter should begin receiving telemetry from perseverance and streaming it to earth in near real time there are a few expected short outages such as when we have a plasma back out or when we enter the peak heating phase aside from these outages caused by the plasma blackout antenna switching or high dynamic events spacecraft events we should have telemetry until about 90 seconds after a landing blackout is when the signal from perseverance isn't strong enough to make it through the superheated super fast air flowing around the spacecraft all the way down to earth once the temperature drops below that peak heating we do reacquire the signal from perseverance we are currently about four and a half minutes from entry intervase perseverance continues to report heartbeat tones indicating everything is nominal whoo baby tamara reports the electro radio is powered on ready to receive signals from the lander mars reconnaissance orbiter has reported that it's ready to receive the signals from perseverance it should be in a few minutes here we're just flight local ones from entry interface so the next thing we're waiting is to hear that it's it's beginning entry so it will actually have entered mars atmosphere around this time a second spacecraft maven should begin picking up telemetry from perseverance and we'll continue to record that telemetry until several minutes post landing we won't get that data for several hours after landing as it's being recorded and then will be forwarded to earth later we are continuing to receive heartbeat tones indicating that everything is nominal we're currently at about three minutes until entry interface so i i feel like people are still asking a lot of questions about this again the countdown clock is about when we should expect to know that it landed um so in in i know this is hard hard to grasp and hard to explain too it takes 11 minutes for us to know what actually happened so right now uh perseverance has hit mars whether or not it hit it softly in one piece as it's intended uh it has touched down on mars it will take us about eight more minutes to actually know to transmit heartbeat tones indicating everything is nominal so i think we have entered mars atmosphere we're waiting to hear official word for sure i might have jumped the gun a little bit but it's we're just under two minutes from entry interface as it gets closer to mars pressure is actually being pulled in by gravity and accelerating by the time perseverance reaches entry interface point he should be going just under 5.4 kilometers per second we had about 90 seconds from entry interface and standing by for mars reconnaissance orbiter to pick up the telemetry all right guys so we're just waiting for good confirmation that has entered mars atmosphere we are one minute from entry interface all right heartbeat check everybody make sure you're breathing this is this is the uh this is the moment here so hopefully we get good call-outs are in receive mode we have confirmation that the microconstants orbiter is now relating data from perseverance we're about 30 seconds from entry interface pressurance is going about 5.2 kilometers per second and is about 190 kilometers altitude above the surface of mars to confirm your jeff data flow so the mars reconnaissance orbiter actually has acquisition of signal right now oh i like seeing that about 5.3 kilometers per second and an altitude of 150 kilometers from the surface mars so just these little blips entry yes we have confirmation of entry interface presidents is currently going 5.3 kilometers per second at an altitude of about 120 kilometers from the surface of mars oh baby here we go the thick is now waiting until it begins feeling the atmosphere slow it down once there is enough atmosphere it will start controlling its path to the landing target doppler indicates entry into the atmosphere navigation is also confirming that we can see a little bit of that slow down of the atmosphere on the perseverance entry capsule our current velocity is about 5.36 kilometers per second and an altitude of about 67 kilometers from the surface we're probably seeing mro plasma blackout at this point so we're getting into the peak entry heating completed and pretty much right about now hammer has lost luck they're around the maximum deceleration reversal reversal we have indications that perseverance is now performing bank reversals in the atmosphere these are the steps in order to control its taxes attached to the landing target press events has just passed through the point of maximum deceleration and has indicated that it felt approximately 10 earth g's of deceleration oh mrl has locked again 10 g's stopper indicate reversal bank to complete we saw a small outage uh of the uhf telemetry from mars reconnaissance orbiter during that peak heating phase likely caused by the plasma blackout perseverance is still continuing to perform bank reversals in the atmosphere to control its distance to the landing target reversal end of range control range minus 1.9 kilometers cross range minus 2.4 kilometers okay so the next thing we're waiting to hear is that they have going about one kilometers per second at an altitude of about 16 kilometers from the surface of mars we have entered heading alignment which means preservance is no longer trying to control the distance to mars but in to the target on mars but instead is flying straight to the target so again they can kind of control a little bit of the the pitch uh by because they although it's just a circle it can actually have some lift forces by having an offset center of mass they can change when they roll like this they can actually have it lift or bank a little bit steer left and right um and they can kind of know out or you know help hone in but now they're just letting it be nulled and just go straight to the site so the next thing we're waiting for is parachute deployment a good callout for parachute deployment her current velocity is about 550 meters per second at an altitude of about 15 kilometers from the surface amarillo's reporting good telemetry lock we are coming upon the tougher start we are starting to straighten up and fly right where the spacecraft will jettison the entry balance masses in preparation for parachute deploy and to roll over to give the radar a better look at the ground indicate shoot deploy shoot deploy baby the navigation has confirmed that the parachute has deployed and we are seeing significant deceleration in the velocity our current velocity is 450 meters per second at an altitude of about 12 kilometers from the surface of mars they're doing it guys i want to see this thing this thing has 20 some cameras that i want to see this footage they're recording this this is actually going to be sent back and uploaded heat shield separation has slowed to subsonic speeds and the heat shield has been separated this allows both the radar and the cameras to get their first look at the surface current velocity is 145 meters per second and an altitude of about 10 km nine and a half kilometers above the surface it's looking good oh man i this thing needs to land it oh i gotta see all these cameras i gotta see this footage so now the next thing you're gonna do is they're going to detach from the parachutes and from the back shell and just let it fall for a second filter converge lastly solution 3.3 meters per second altitude 7.4 kilometers now has radar lock on the ground current velocity is about 100 meters per second 6.6 kilometers of the surface okay get ready the detachment freefall is terrifying perseverance is continuing to descend on the parachute we are coming up on the initialization of terrain relative navigation and subsequently the priming of the landing engines our current velocity is about 90 meters per second at an altitude of 4.2 kilometers so close they're so close ovf salad we have confirmation that the land division system has produced a valid solution and part of terrain relative navigation rhyming tpa is nominal we have timing of the landing engines they're getting ready to detach and free fall back shell set back shell set 83 meters per second at about 2.6 kilometers from the surface mars we have confirmation that the back shell has we are currently performing the divert maneuver current velocity is about 75 meters per second at an altitude of about a kilometer off the surface of mars trn safety bravo we have completed our terrain relative navigation current speed is about 30 meters per second altitude of about 300 meters off the surface of ours sds level 140 we have started our constant velocity accordion which means we are conducting the sky crane about to conduct the flight crane maneuver we've lost direct to earth tones throttle down skytrain maneuver has started about 20 meters delta tango delta touchdown we're getting signals from mro remus stable uhf is good [Applause] [Applause] yes yes that is awesome at this point the deceptive stage has flown away to safe shifts perseverance is continuing to transmit direct through the mazda orbiter oh that feels good that's what we yes yes oh that's what 2021 needed baby that is awesome oh they have to feel course they're still getting telemetry from the lander all right so right now the sky crane is actually flying touchdown confirm we're gonna wait for the images [Music] now we're gonna get some images already oh my gosh come on that is amazing oh how do they do that hopefully yeah hopefully we see some some pictures and data coming back very quickly that is awesome it's already tweeting i'm safe on one you have what you need slightly i have what i need we have seen the completion of edl 3000 copy copy activity that is as expected someone's comms are on camera is still seeing a strong signal from the lander light this is ol3 i am ready to share someone's getting emotional on there oh well three you are go uh for those on in all stations stand by for the images yeah let's see it let's see it [Applause] [Music] oh that's awesome i love it it's just this teeny little blip for now low res image for right now but flight this is ol3 i have uh the target point on the map when you are ready we are ready ll3 go for it where do they land i bet they can't wait to know where exactly they landed flight i'll be uh moving in showing you the safe zone that we've landed in oh that picture is awesome so again as they have more and more bandwidth they're going to start uploading as much stuff as they can telemetry all the data images videos and audio oh i cannot wait flight so i think one of the big things we're going to be waiting on now is where exactly has a touchdown in the jezreel crater where n t r i don't think people know their mics are still alive that is hilarious can we get the cliff image oh well so don't worry this actually the perseverance does have color cameras so at first they just uploaded the lowest resolution images possible basically can we get the other image should show the cliff show a cliff are they standing next to a cliff see what m is again i'm not understanding flight ol3 for all three uh you can see we've landed about 35 meters from the nearest rocks that we could identify from orbit by their shadows oh cool copy oil 3 crn in action yep take that jezero i remember this spot it looks good that's awesome coffee ol3 i'm sure that you have seen them all and you recognize them all so whoa so getting views of cameras from all around it it has cameras all around the deck and some really really high image like a 24 electric still in lock with the lander we have seen the transition to surface edl is done [Music] transition to surface that's awesome it has officially transferred into being able to use surface ops now so it's no longer thinking it has to worry about landing it has landed it is officially beginning operation on mars perseverance team and the whole team that's not here as well excellent job a reminder adl entry descent landing so that's what we were just basically seeing for the last especially last like 10 minutes was the entry descent and landing portion uh it is officially out of that now it does not need to be worried about landing on mars it is on mars it is sitting there ready to go ready to start transmitting back images the video from coming in from entry this will be the first uh good quality video with audio through entry of mars ever downstairs uh if you're part of that story to the surface team make sure you're starting to work those inputs please um this is a good question um eric i think uh referring to tangley isn't the sky cream considered as first powered controlled flight on mars because you might be hearing people say it's the first powered flight or controlled flight on mars when they're talking about the ingenuity helicopter and i think they often forget to mention aerodynamic controlled flight it's where it's using the atmosphere only you know obviously skycrane for curiosity and for perseverance both are using controlled flight using but technically uh all under the you know thruster fire uh so it's not anything with aerodynamic forces it's using controlled flight schemes by by thrust vectoring by using differentiating thrust sorry not actually thrust vectoring that the thrusters are actually stationary but it has differentiating thrust just like again like a drone normally would or a quadcopter but um but there's the the four different basically on all corners of the vehicle they can control its entire uh trajectory and it's landing softly in all of its control using just those thrusters so yeah that's uh that's a good thing to say so or good thing to notice so um the success of of mars missions will change today they i'll tell you what guys nasa jpl lockheed martin they are absolutely knocking these out of the park this is now how many landers in a row i mean this is al-2 voice check hey listen i just want to announce to everybody i've taken a first pass at the surface transition report i've got some numbers from the script and i'm awaiting inputs from a couple people still and confirmation from others it's ready for review copy at the end of that was it's ready for review are you asking people to take a look at your cash report that's right it's ready for review um i'm hoping i'm looking for confirmation from a handful of folks on some of the values before making it final poppy do you want that confirmation over this net uh the process is to work it over email i've sent out an email that they can reply to thank you yeah so this is the third lander in a row now for the united states the last one that failed for the united states was the mars polar lander and that was in 1999 so it's been 20 years three landers now all successful going from curiosity to the mars insight lander and now perseverance on the surface of mars um operating successfully so that's uh that's pretty incredible uh again just to put that into perspective because mars is really hard um the last missions outside of the united states um there's a this is skiaparelli lander um which was a joint mission with isa and and russia that failed um in 2016. the united kingdom had a failed lander in 2003. uh russia had a failed in 96 basically from there on out it's the soviet union's only had a a partial success other than that the united states uh and nasa jpl um have really been the only ones that just nail this and so it's it's pretty amazing well i think one now they have a system in place it's just absolutely incredible so wow can we go ahead and get a handoff ready to go for our final monte carlo for today uh this is ted one already working on it kathy can you tell me what od that's on the latest one i have is 137 i can i'll go jump into the nav room and confirm that's the last one coffee oh well this is top one we're ready to run that monte carlo when the handoff is ready coffee thanks top one chat one this is chad two you might hear them say monte carlo that's those are simulations so they're gonna be plugging in the data that they got back and see the exact i think believe i'm guessing they're going to want to look over the exact edl and but i'm not entirely sure what they're doing monte carlo for now it's a tad one is currently talking to nav standby um a friendly reminder two people are wondering what happened there are actually as we speak there are three mars missions that have been successful this year so far um all three of them took off last summer 2020 um we have the hope lmr mission alemal mission which just got into uh orbit uh last week we also got the um tion one when so the uae was the hope mission and tian one is china's mission so far all of all missions are successful but those um so far are just getting into orbit of mars they're doing the hope mission is not going to land so it's just did an uh uh basically a capture burn and in a couple months it'll do more of a circularization burning get into its operational mission so we kind of have to wait to see if that's successful and the china mission will be hitting the atmosphere uh it's in orbit now and it's going to be just kind of getting itself ready to land in a couple months before we started this one or if i should get uh hbc on it so you can focus on the handout how far along is it 5700 cases uh yeah i'll go ahead i'll go ahead and kill it um i get that one this is a good question here um when will we get the video and the audio from this because again they actually did record audio uh of entry descent and landing for the first time so it'll probably take a while notice that the images that we're seeing coming back are very low resolution just single still images you know video has between 24 30 to 60 frames per second so if you're going to have seven minutes of high resolution images and audio in there it's going to take quite a while to be able to send all those packets of data back up from mars and currently it can use the mars reconnaissance orbiter to have a faster uplink but it will still take quite a while and i i don't have an exact time i'll be listening in if see if they mentioned anything about that how long it might take but it will take quite a long while before we see higher quality images higher quality videos and stuff like that so um yeah we will uh we'll be listening in here but i wanted to thank you guys all for for hanging out with me today uh we'll be listening in for quite a bit longer keep learning and see if we can uh see if they start mentioning any any fun facts about where exactly they landed um that's kind of the next thing it's going to be a long time before they really start roving around on mars um but for now it's it's definitely time to celebrate it's definitely time to be excited and and just have a sigh of relief a collective sigh of relief for everybody even those of you watching it's it's okay now just uh big ol fat cheers let's see it in the chat everybody just cheers to jpl nasa lockheed martin uh cheers to mars uh cheers to humans doing awesome things how about that that's that's what i think um this is you know the friendly reminder of just how incredible humans are and the fact that we can send something that weighs a metric ton so like 2 200 pounds or whatever it is uh to the service of mars that's going to be driving around and then it's going to be flying a drone around on the surface of mars i mean this is this is awesome this is the stuff that makes me just really excited to live in this day and age this is the type of stuff that just makes me happy and excited and looking forward to the future because we are able to do awesome things like this so hopefully soon i still think in this decade there's a small chance we might be sending humans off to off to go walk around on mars and maybe pick up some of those core samples that this that this rover will be picking up that's one of the fun things about this mission is it's going to be drilling into the surface of mars collecting them into tube samples and then caching them and having kind of a a bank of them um where something else can come along and pick them up and so we'll have done a lot of the work for them they can land and just put them on a small rocket uh and send that back to earth or oh hang on everyone everyone this would be a little update all right all stations congratulations but believe it or not we have a job to do now oil one sad one ghost had one are we ready to uh look at the surface flight this is flight yes please should i go ahead and just share it in the webex that we're working now yeah please all right go ahead flight i want to confirm that your team is ready to receive perseverance um i am paying attention copy we are ready to receive perseverance okay are you ready for it uh the new one is on the left not yet uh one point on the right uh we'll let the team here have uh not yet we'll all right here um a few minutes with the telemetry and then we'll do uh our briefing remember to put the details in capture for your counterpart yeah so od 137 spread then we will do an overvolca and i don't think anything else actually changes like this 50 are you staying on the ups or other than so i think it's going to be a few minutes before they get something figured out here uh but before they do a briefing um and they're definitely talking over what the next steps are here so uh meanwhile let's uh let's keep going here for you guys um this is from uh dark zak would the 10g mention be safe for the average human after a voyage and micro g's i don't know the exact i mean humans can survive 10 g's but yeah would that be the best idea after experiencing six months of weightlessness probably not a human profile would have to be a lot a lot lower g loads than 10 g's i think that'd be too great of a shock i mean i don't think you'd die from 10 g's um but i don't think that's in the best interest of the astronauts that would be on board of a vehicle someday that's why one of the things about starship is that because it has such a large lifting body it can actually stay up in the upper atmosphere it has a lot higher lift to drag ratio even though it's not using those flaps like wings at all just using the fuselage of starship it can tip up and stay in the upper atmosphere longer and have a more gradual lower g load okay hold on your efforts to you and your team and for giving us a great great uh trajectory here you're welcome pdlol1 or three this is udl phase on udl ops phase this is ol1 can we get a copy of those uh pictures sent to me the uh where the map is or where we came down where we targeted both in hazard map and not hazard map mode oh well three gave me a thumbs up you should have those shortly um people ask me how how many g's is something like the dragon capsule dragon capsule i think peak at uh highest point in re-entry the highest uh that they're supposed to ever experience i believe was five um with more of an rms like an average of about three g's so 10 g's is substantial 10 gs of load is substantial yeah i'm saying that instead of getting out champagne and they're having to pass out having to pass out hand sanitizer it's not quite as fun let's see here let's see here so uh thank you guys so much um for all of you again for those of you that um are are listening and watching if you guys do want to help me continue to do more uh one of the videos i'm working on right now that's taking a lot longer than i thought because when you don't have internet or power or running water it's become quite hard to make videos but the video that i'm working on right now is why exactly starship does the belly flop maneuver so going into the exact physics of why they're doing it so late why they're doing the flip maneuver while they belly flop is it safe will ever be safe for humans so we do talk about g-loads on humans we will uh yeah we will be we will be doing um a really really deep rundown a lot of good animations talking about things like thrust to weight ratio gravity drag slash gravity losses we'll be talking about uh a lot of and let's see terminal velocity uh it's going to be a really good video um it's about 40 minutes long so for those of you that like my deep dives this is a very deep dive um and it's an important reminder of why starship is doing something so radical and so different and why it why like why is it worth doing that so um it'll be a really good video i again i have to apologize that it's taken so long i thought that i was gonna be done with this a week ago but um it's been a harder video than i thought and put on top of that no power no uh internet and stuff like that has made it very very very difficult so um if you guys do want to help me do stuff like this and make uh all the videos i make better and higher quality and to be able to produce more and more and hire more people to help me do what i do uh consider becoming a patreon supporter by going to patreon.com everydayastronaut so patreon.com everybody astronaut you can join our awesome discord channel um you can hang out with our awesome community ask questions help provide answers for me because i obviously don't know everything and i learn a lot from our community all the time so um come say hi it's a really fun place um also i did want to mention i do have um we do have this shirt the entire future martian society collection on sale today um with you can use coupon code touchdown all one word lowercase touchdown and you can get 10 off of anything in our future martian society collection um the fun thing about these shirts is they have a lot of extra details um such as you can see the little like on the sleeve here it shows you the exact martian atmosphere the gravity uh reminded to wear a spacesuit but then the cool thing is on the back here it does show arcadia planeta and the exact coordinates of where starship might land someday so this is a really cool shirt you can get your own by going to everydayastronaut.com shop and uh and use coupon code touchdown for 10 off of anything in that lineup today i'm or you can be like elon and his and baby x uh i don't know if you saw the video on twitter the other day but baby x was seen wearing a full flow stage combustion cycle hoodie or not a hoodie a onesie it would be he'd be really cute in a hoodie too but um yeah go to everydayastronaut.com if you guys want to support me and get some awesome stuff for yourself as well but uh meanwhile let's go back to this voltage when we transition to surface the indication of the tone that we got thank you michael like we have cleared or it's likely on the dpm correct flight i don't see any indications from the evrs that indicates that we re-tripped some rpam related monitors and we'll have to look at the recorded evrs when we get them down to see what exactly happened but it looks like um at least what we have so far that whatever it was has since cleared copy fp well thank you very much from tech i really appreciate that or from oh i might think i kind of messed up from john hart uh i had a very generous donation thank you very much john hart uh said my patreon method payment method got messed up uh without me knowing for a while hope this helps make up the difference well thank you very much john that's really not necessary but i really do appreciate that um yeah you guys are awesome thank you so much for all those uh that have helped me make this a career not just a little uh dream so uh you guys are amazing including david here saying uh hopefully this is well it's it's not working uh i'm not sure why this is happening but um i will try and fix this but but we did have um david hernandez also from from mexico thank you guys so much let me refresh and see if i can get it let me listen here pyro safety status is reading 268 ohms which is armed and disabled um pyro crcs are still enabled um from the end of edl and the rpfa is powered off avionics maybe young's flight voice check all right let's move on to telecom we'll get back to you yeah flight telecom design had got very very little telemetry during edl itself and on the surface once we landed however judging by the performance we can say that telecom is healthy certainly the defense stage radio and amplifier did its job spectacularly the electrolyte a worked spectacularly we are we did do the final switch to the rough antenna on the rover otherwise we wouldn't have been able to talk to mro after landing so we know where the switch has connected electra a to the rough ready for the first relay pass which will be odyssey in a couple of hours and other than that telecom is healthy and it'll go for surface operations wow coffee thermal thermal is nominal and as expected we have limited data which again is expected we saw a 50 degree increase on the rtg after the hrs event which is in line with both what we expected and what we saw on msl that filtered in we've seen some small increases on ramp and associated hrs electronics as expected everything does look everything is nominal right now flight this is flight software flight software performed and is performing excellently health monitoring has been restored on the transitional surface we show earth in control everything looks green copy how's your sub system doing on the surface it's it's doing great uh acs gave a great pep talk to the nav filter giving it a good attitude for edl telemetry look great just before his idol then presumably acs is now sitting in a new crater on mars coffee and prop how much fuel did you leave the uh crew stage burnt up with 55.91 kilograms of propellant and the cent stage consumed 305 kilograms out of the 401 load so we flew away with about 96 kilograms of propellant but otherwise propulsion performed nominally we did the successful boot of the dmca into msw mode as expected we then did see uh successful activation of the eight tvas and they were nominal closure fly away was then commanded nominally and the warning evrs after closing fly away are expected copy dmx so to put that in perspective the sky crane itself only used about 75 of its fuel so it actually still had a good remaining amount of fuel 25 left that's awesome um do notice that they measure everything in kilograms a lot of people will be like you live in america why aren't you doing america units um you know obviously i grew up with imperial units like most of the the rest of us in the united states but don't forget nasa has been using metric almost the entire time uh spacex all the other aerospace companies all use metric um exclusively so we heard them measuring the weight of the propellant in kilograms so in different places on mars one of the most important pieces is still on the rover the vce is healthy throughout all of edl performs its um job admirably and has the data from entrance landing so is go for cell one activities to retrieve that data copy gnc and ace flight ace all of our systems worked as expected we have disconnected from the command system and we have all four stations standing by for us to release them copy so at this point the release i'll leave to a surface flight and surface space is that are you going to be surface acer these stations won't be around when we're when we're using them the next time i understood they're probably done for the day but i don't want to presume anything i'll leave that up to surface flight to figure out copy that okay and i left the last here activity lead uh is it activity lead one or two activity lead two all right activity lead two flight this is activity lead 2. i can confirm that edl was nominal as we know i've filled out the cashier report with all the key details about the landed lat long position the estimated touchdown velocities we've got a estimated rover attitude in three dimensions from remu real-time data products in there and everything is nominal the one piece we're still missing is the mro loss of signal time but i'll be adding that to the report as soon as possible and we cannot assess the state of the edl cameras we didn't get an eha update since prior to entry but otherwise all as well copy activity avionics can you copy i got you it says rc alpha is prime rc bravo is powered off from the pre-deal yha the prime-ness is as expected we don't have any additional telemetry at least i don't indicating whether we swapped pams or not but the rc spans and buses are healthy the old pam states are so everything is looking really good i wanted to answer a few more questions for you guys here but everything so far from what i've heard is just uh incredible um this is a fun one from rad how many more years until we stop getting excited about landing like in the movies well landing is finally becoming less exciting for something like spacex's falcon 9 where it used to be this big scary deal and now it's totally normal right um we are more shocked when it doesn't go well like it did with the other night's starlink mission um so my guess is it probably takes about 50 times of something happening relatively closely together before you stop before it becomes routine so we're at three now in the past uh basically 12 years or whatever so uh i i think it needs to become a lot more routine and normal than that like probably 50 a year so i'm guessing it will be 30 years from now before that's gonna be even remotely close to the reality so uh it's it'll be it'll still be very exciting when things land on the surface um in my opinion um from um laj christensen says well percy so well perseverance rover uh record the first flight of the ingenuity helicopter greetings from denmark well hello denmark um i i think it will and it literally will point the camera's ad ingenuity and hopefully they both can record each other and get awesome never before seen video um on the surface of mars i'm really i know that it is actually the plan to watch the flight the first flight of it so that would be super super cool looks like they're running a little artemis ad here while they're kind of doing some stuff um so about the onboard helicopter ingenuity uh james wants to know do i know when they'll first fly the helicopter i don't remember i don't know if we've heard an exact date um if i remember right if i remember i think they let go of it relatively soon um yeah anybody do do you remember i don't know if i've heard actually um yeah from rizzy well thank you very much um from tc um what's the signal delay did it land uh that amount of time before we found out and celebrated or was that live so uh to tc it there's 11 minutes of communications delay so what we were celebrating was when we got data back telling us uh that it landed 11 minutes ago basically right so there is nothing that you can do in between that it's all autonomous so it's just a matter of like holding your breath and hoping so so in real life uh it was about it was about 45 minutes ago from right now it landed on the surface but about 34 minutes ago or so we actually heard about it and knew for sure we got the data back um yeah and and that's uh pretty awesome um from flight coach wants to know uh one vital question remains where is the mohawk guy so bobak fordosi yes i actually had bobbik in my video about perseverance so if you actually want to watch this video here guys type in when you're done type in curiosity versus perseverance and i give you a very deep rundown on the exact hardware differences between the two rovers the similarities but importantly i even had a interview here hang on boop i have a little bit here from bobakfurdosi he um answered a couple questions here um in my video so definitely check that out he is on a he is on a different program now so he does not do uh you know he was there for curiosity i don't remember his exact title now but um i don't exactly remember but he's still at jpl he is still at jpl just not on uh on perseverance so that's a good question um yeah uh this is funny from from um excel says normal for those of you that don't know what normal is uh it is just it it's stems all from a a spacex here i'll show you guys here um it's it stems from here is the normal wait that's not the normal hat from john and sprucker from spacex one time said it on air and it's obviously mixing up the words nominal which we heard them say which means everything's going as planned and the word normal which is of everything's going normal he said normal so on july 5th 2017 um spacex principal engine integration engineer john insprucker accidentally said the word nominal forever cementing it during um 35e so yeah so that's where norman will come from it's kind of an inside joke in the aerospace community that everything is going well so even though you'll hear nominal um around here normal at least like if for me and my community and kind of some of the spaceflight community normal just means it can be good it can be bad it can just be space flight like literally when things don't go right and you're kind of laughing about it that's like when starship blows up that was normal you know it's it was halfway planned halfway as expected so yeah that's what normal is for those of you that that feel uninitiated to it don't worry i know it's i know it's not nominal and i know that it's not normal i get a lot of people hey you misspelled normal like are you misspelled nominal it's like yes because it's not nominal uh keith uh thank you very much i'm trying my hardest i promise like i said it's been the last couple months for me or you know really the last month has been very challenging trying to do sn9 uh trying to get a studio space down here in um in south texas um yeah and then now for the last week basically not having power and data and water it's uh and below freezing temperatures it's been very hard we've had uh yeah it has not been the most fun week of my life this is a nice little reminder that things can be exciting and worth looking forward to um yeah so so thank you um i try i don't want to set the expectation guys people are like tim you're missing this event my job has never been to discover every single spaceflight that was never my intentions with his channels to cover all spaceflight events i'm here to cover what i want to cover when i want to cover it i'm not a 24-hour news channel that is absolutely not my job my job is to bring space down to earth for everyday people is to help cover and teach you guys something so for me one of the hardest things or making these videos the videos that i make take a long time i have now spent like 14 hours on one dumb animation uh andrew my my co-producer has not been able to really help with this video at all unfortunately because he's busy he shoots for espn so he's very busy right now with um the nhl schedule so i've been having to make the video entirely by myself which again with no data uh no power and things like that has been made it very difficult but that's what i love to do i love to take these topics that are really in-depth and really uh really almost confusing or intimidating and try and make them you know more easily understandable more digestible so that's what i like to do best that's my priority is doing those um so kind of just so you guys know just a personal priority for me is is making cool videos and helping bring you guys um historical events and help break down the science and and what's going on behind them so it's you can be excited and you can think this stuff is cool because i think if you don't understand this stuff it's kind of confusing on why is it fun and exciting um and for me starship is is a huge pull for me because it feels like the wild west out here i don't think i'll ever be able to in five years cover a rocket like i can starship so it is extremely important for me to be able to build a studio space down here and cover starship as best as i physically can so um yeah so that's that's kind of my priority in life and i hope that you guys are cool with me working on videos and trying to get catch all of the different starship launches um yeah it's it's a nutty time and i'm just excited to be able to to provide this stuff for you guys so it's it's insane um thank you very much uh mary frances um and jennifer for the the memberships you guys are awesome um hubert says with a pear character thank you very much charles great work love your videos cheers for more well thank you very much norway i can't wait to be able to travel internationally and go back and see gorgeous norway hayden uh why don't they use the delivery vehicle as a permanent lander instead of just crashing it so we ca we kind of talk about that in my video um why don't they why don't they just land it on the surface you know and then have the rover drive off of it and stuff there's a handful of reasons um but as we mentioned at the beginning of the stream one of the biggest reasons why you don't want to do that is you actually you really want to have all of your mass on on the vehicle driving around right if you have the option of having it be stationary versus having it drive around so we're actually going to see something similar like you're talking about um on china's tian when tion wen won mission that will actually have um a a lander with some science instruments a rover a small rover and then a uh and then um an actual wait uh no it has an orbiter sorry a lander and a rover so there's some science instruments on each but you know i think the the idea is like why not just put all of your science instruments on the thing that can move around safely it actually takes more you know if they're making sure the the sky crane lands softly um it's going to require more hardware and require more fuel it would have the potential to still potentially land on curiosity um it would require more mass for landing gear basically you might as well just put all the science instruments on the thing that can rove around and drive around there's really no point in uh at the end of the day and trying to have something else sitting on the surface of mars that can't move um when you have something that can move around it's actually lighter weight to do it that way too so this is from bryson thanks for all you do tim uh stay warm thank you very very much bryson it's getting better down here uh you know in south padre basically but it is still very bad in in northern texas and the big deal is for me i'm an iowan don't don't forget like i can handle well below freezing temperatures it's it's a normal part of my life uh every year but down here the buildings and the infrastructure are not set up for it so i know a lot of people around the world like i live in norway and and it's you know it's minus 30 degrees celsius for three months of the year whatever you know it's like yeah i get it trust me i live in a northern climate too but um texas is not set up for that texas doesn't have any of the things um to be prepared for that so it's just completely shut the entire state down you know it's 39 degrees here right now and um 39 degrees when you're home in a home with uh with heat a lot of homes down here don't have heat including the one i'm in right now does not have heat we don't have a furnace there's a small space heater and that's it um the and we're lucky to have that because a lot of houses still don't have power mary liz and ryan's house from cosmic respective happens to have power right now which is exactly why uh we're doing this here and uh yeah it's not always an option though so um the houses don't have the same the same insulation it's just kind of it's kind of a mess and so staying warm is an actual uh real issue so um yeah so thank you very much bryson i really do appreciate that i'm feeling hopeful that by you know by the weekend hopefully things will start getting warmer and better and more power getting on and all that stuff so um yeah um so thanks to all of you for for the support too um jmn thank you very much um like i said though my goal now with with the studio space is i definitely want to have full-blown power walls or like battery backups on the entire you know on the entire studio i want to be able to uh you know stay off the grid for like two or three days and then have solar and a small wind turbine or something so that i can cover starship no matter what you know absolutely no matter what no excuses um i think that'd be awesome all right so that will be where all of all of this month's uh you know patreon support and all the the support here too will go right into making sure that i can provide you guys coverage no matter what uh thank you very much um you're welcome dale i i can't wait for you guys to see this belly flop landing maneuver video it will be very good it's supposed to be a short one like i always promise and i know that a lot of people are waiting for the soviet rocket engine video that's going to be the full uh full family tree of the rocket engines that came from the soviet union and now russia and ukraine um that one is just such a big undertaking that i'm not gonna even touch that one until i get back home to iowa um and then get back to that studio um unless i mean maybe if studio b gets fixed up and if i'm done you know starship i need i need to be done like chasing starship to be able to shoot that one that one's going to be a very long video it'll be a full-blown documentary some that one needs its own amount of focus and attention and drive um so that one's just kind of sitting here it's it's done script uh the research is done all the hard parts are done but shooting and editing that is going to be a big undertaking i need andrew uh to be able to be not in the middle of eight uh nhl season two for for that one um because i want to be able to we'll take both so um yeah and discord short video now equals sub 60. i i feel like short videos for me these days really are if i can do a 20 minute video spoiler that won't happen uh that would be a short video uh medium video i feel like it's now about 40 minutes which is what this one is and then my like longer videos are now 60 minutes but um yeah i uh i'm really excited though there's a lot of fun videos coming out i just have to have uh something called free time to or just period time to be able to do that on top of trying to build out the studio and not freeze to death so i'm really excited um brandon uh stoked for you that this is your job just want to say thanks for all your content and thanks for covering these events you mean a lot to a lot of people can't wait for you to cover humans landing on mars well thank you very much brendan that is my ultimate goal is to be to still be doing this i don't know if i can hang in there for 10 15 more years doing exactly at this capacity because it has been a sprinting marathon for the last three or four years but i do want to still be very uh prevalent and and um still very active when humans do land especially on the moon and and again on mars uh not again sorry more like again on the moon uh but that's more you know near term to me i think that's could be in the next five or six years um and then maybe you know hopefully i'm gonna be around and able to cover the first humans landing on mars with you guys um that would be awesome that that will be awesome uh mark will the copter be able to clean its solar panels from dust buildup uh i'm guessing that by flying just the airflow produced by the uh the dual rotors all that extra the motion of air even though it is one percent air it should hopefully probably clear its solar panels um solar panels really aren't i mean people get so worried about you know about them getting covered but don't forget um you know we had uh what is the little tiny rover right now i'm totally blanking on this um you know we did have um uh what's it called not phoenix jeez inside thank you no wait no what was the one that roved around forever was it insight no inside was the lander um opportunity there we go yes thank you opportunity roved around forever using solar panels i mean it lasted so much longer than anyone expected so i really don't think that the dust buildup um is is too big of a concern so um yeah or not as big as a concern as we might think and by the way we'll be lucky if we the the the helicopter is really honestly just a total bonus like if it works at all it's going to be huge so um yeah um so if we get two or three or four flights out of it that'll be amazing so it's just kind of like a bonus thing they're trying so don't get your hopes up if it doesn't work um yeah 14 years is how long opportunity lasted it's supposed to last like three months i love that um yeah um from kloss hi tim an awesome crew i'm so happy watching your shows every day um being so down to earth seems like a contradiction to the subject you transmit but i do love uh you girls and guys for it greetings from denmark uh the land of future power supply that's awesome don't work um yeah thank you very much it's been it's been a lot of fun being able to cover this stuff and for me to learn you know that's the whole point of what i do is just to learn as much as i can and then help try to transmit that guys transmit that for you guys as well because i know how intimidating a lot of this stuff can be i don't have a formal background in anything aerospace related um definitely not in anything astrophysics or anything like that at all um so i am all self-taught just like a lot of you are and it's important for me to remember that this stuff is hard and it's it's complicated there's a lot of little details and a lot of fun engineering just challenges and decisions that they get to make all the time um so yeah let's see here um from daniel i wonder within 10 years will nasa be using starlink mars editions for data transmissions yeah i did talk about that for a little bit i really do think at some point it'll make a lot of sense to just send a small handful you could literally have you know four or five you know six starling satellites at a higher altitude around mars to be able to provide the biggest issue with mars right now is is the row is the orbiter's um you know there's only a small handful of orbiters that are capable of relaying data so it has to be overhead and in sight in line of sight for the landers or the you know the the vehicles to be able to upload data to say mars reconnaissance orbiter so um so there's only a certain amount of uplink time so now if they were to put a new constellation around mars with starlink satellites that would be huge you wouldn't need as many of them because you're never going to you know you don't care about latency you could have them way out there on mars so that are always in line of sight but the latency doesn't necessarily matter nearly as much because it's going to be 11 to 20 some minutes for that to get back to earth so a couple extra milliseconds of delay of latency getting up to the satellite is absolutely irrelevant so yeah just a small handful would be awesome um david graper thanks for all your amazing information you provide during your videos well thank you again uh i almost wish i might be able to pull up a little bit of a teaser here um i can show you guys here i'll do this this is uh give me one second i'll pull this up i will show you guys a little tiny miniature teaser here of what i'm working on um as we speak for for this upcoming video so like i said this video will be about um how why they belly flop starship and why it's doing that um landing burn so i'm working on animations showing the differences between uh acceleration at different thrust to weight ratios there is one that shows um a lot of stuff yeah this is another one like thruster weight ratio so i've had a really hard time matching acceleration graphs and stuff like that but it's getting there i'm really getting closer and closer and i i really do think that these images uh and all all the different information on screen will help you understand this stuff in a really intuitive way you know that's what i think is so important i'm a very visual learner myself so i know how important it is to learn using you know graphics that teach you these concepts so i've been working on this video for way too long now like i said i do deeply apologize that it takes me so long to do these things but i think it will be worth it i think this video will will help you understand um these these specific things uh very well and you'll and you'll know why starship is trying to do uh that belly flop to tail down landing maneuver and why they're doing it so late uh we'll give you all the data behind it and i think you will really like it so um i don't have an eta on it i would have thought i would have been done by now a long time ago like i said i thought i was gonna be done last week but hopefully um we'll be done next week but i don't know now i'm already getting back into we got to get the studio finish built out so that i can do uh my first uh for sn 10 live stream from there so that that could be coming up here i'm guessing next week um it could be any day but i'm guessing about next week so yeah all right um thank you from from chechia from chechia big fan of your work uh thank you i'm excited for you guys to see it again um nicolas says um or or nicola says um i'm looking forward to spacex offering sightseeing day excursions to see perseverance lander keep entertaining and educating us tim thank you yes that well first off thank you um but i am excited for something like that too because a few i don't know if you guys have read or listened to andy weir's um artemis uh book but it's really good and he talks in there he has this like situation where humans are permanently living on the moon and they can take tours to go see the apollo 11 landing site it makes me really excited to think that that will be a reality someday yeah let's see all right from um bergsy 2.5 million viewers wow that is awesome and thank you for for getting a future martian tea to celebrate i really appreciate that um that's insane that nasa had 2.5 million people watching live that is huge that is uh that's very very good news that people are actually paying attention getting excited and that the general public is is hopefully learning and being inspired and thinking that this stuff is um something to look forward to you know that's what i'm a big fan of um kevin huff um interesting thank you uh oh use this to your youtube premium i actually do have youtube premium but i'm not sure but thank you i i do have that i might not be signed in on what you guys are seeing but um yeah all right um c1 thank you for the membership um from simon yap um spend on your new studio from simon yap in the uk um i hope you get your model 3 back soon and the weather gets warmer like i said it's been a rough texas has not been very nice to me this year you know my car is still in the shop my tesla got hit in early january down right next to basically sn9 like literally basically right in front of sn9 got smoked by someone coming off of boca chica beach that was not fun uh andrew and i uh are okay we didn't have any any problems but um yeah um but you know between that and then now half of texas getting shut down with with bad weather and all this stuff and i had a pipe burst in the studio and i had to deal with that on sunday with the freezing or monday with the freezing temperatures and no power it's just been it's been interesting it's been a week but um it's been a month i guess hopefully hopefully this is a good sign some good karma that things are gonna get better here so yeah um all right so from c1 how will the core sample get back to earth so um again don't forget guys i do have a video called uh perseverance versus curiosity what's new what's upgraded what's different definitely give that a watch when you're done here i promise it'll probably answer a lot of your questions um but one of the big the big things is there is a planned isa mission where they will go and land at the jezreel crater and uh all of they'll take a couple of the cached samples uh and i'll have to robotically put them inside this little tiny rocket and then launch that rocket back to earth and the earliest that could happen is 2030 so um it'll be a little while all right um jj thank you for the membership um douglas bolt thank you for the membership um space art by christopher dahl great coverage everybody astronaut i'm thank you for all your all your great feeds and content love what you're doing well thank you very much uh c1 my son ryan wants to know how the core symbols get back to us yes so sorry there uh so you wanna just answered hopefully you are able to get that but yes they will be sending another mission and actually will be a partnership with issa um so uh europe will be going there and hopefully right here we're seeing it perfect timing uh yeah so it needs to be developed relatively soon um and then it will rendezvous basically they'll launch that into mars orbit it'll rendezvous with another satellite in mars orbit and then get shot off back to earth so pretty nuts pretty nuts uh for those of you just now we are waiting for so it has landed they successfully touched down perseverances safely on the surface of mars which is huge go ahead and celebrate uh amongst yourselves everyone it's extremely exciting uh we're they're kind of re-jigging and getting ready to uh you know actually begin the mission already so we're kind of waiting to hear a little bit more back hopefully see some more images and stuff like that so all right um sergio sandoval says by the way i think jpl was able to receive near real-time data using uh the marco cubesats and mro they mentioned they only had a couple seconds of delay in the data stream so the marco cubesats just did a flyby um those were with insight rover the cubesats uh i'm pretty sure marco and b are are gone that was only a flyby um the only thing they had was the mro the mars reconnaissance orbiter um but as long as it's in line of sight yeah they pretty much don't have any um data packet loss but of course real time is relative when you're dealing with the speed of light so yes it was a direct connection continually streaming the whole time but of course it was delayed by about 11 and a half seconds so um yeah um all right so forbidden where's the sky sky crane now great videos always enjoy sky crane is now in its own crater it made its own that sky crane right there this is perfect they just keep showing b-roll and i happen to be talking about it sky crane flies away and intentionally just yeets itself out of there to not damage the spacecraft or the the rover at all so it actually just turns on its engines and just gets gets out of dodge as quickly as possible right and so um where exactly it's it's within a kilometer or so or two kilometers i don't know exactly how far it actually flies away and then it crashes it just gets out of there um yeah uh john little uh thanks for everything tim stay warm stay safe and hope miku comes back even better than before sooner than later i hope the rest of the crew and other stream teams are safe as well yeah i think the only as far as the other team streams so i think nasa space flight uh i believe you know jax basically jack byers is the only one that really comes out here besides mary who lives here full time of course she lives in boca chica village full time um i think i haven't heard anything i think she's doing fine i think the village actually has power most likely thanks to spacex and their solar farm and generator um and generators but um but yeah i think like jack with nasa space flight is is probably fine i don't think there's really anyone else out here my team right now is stripped down to um alley and then cosmic perspective and then my parents are in town right now so um yeah it's uh there's not a very huge crew right here with me right now so um yeah i wish i could celebrate with the krispy kreme mars donut but unfortunately i don't know the nearest krispy kreme is probably just doesn't have power and like five hours away um matthias uh so the size sky screen the sky crane basically crashed somewhere else on mars exactly right yep it crashed i mean relatively nearby like i don't think you can fly more than like 10 kilometers away but it crashed relatively nearby all right um axel says thanks tim i really appreciate the hard work you do for us space fans well thank you very much axel um robert thank you so much uh for your membership i appreciate that from peter um thanks to your enthusiasm and expertise has made a locked down family in the uk very happy well thank you very much i just like i'm glad that there's people out there that are as excited about this as i am um pk keep up the great work thank you so much um michael wants to know how does ingenuity control its horizontal movements with just two counter rotating blades that's a fantastic question especially because they can't they don't have any active pitch control or anything on them um if i remember right it's actually all just about center of mass so i think they just wiggle the uh and adjust basically the center of mass uh dragging off the bottom two rotors i think to basically just steer it around it's a very simple uh mechanism and a simple control scheme um they yeah the biggest deals of those counter-rotating um rotors just cancel out the roll so if you had just a single rotor you know your rotor you would just be spinning that's why you normally have a tail rotor on a helicopter by having counter rotating blades they cancel each other's rotation out so it doesn't induce torque doesn't start to spin the vehicle um so those those two forces are going to be equal and then literally i i think you can i think if i remember i think it's just literally like leaning the body of the helicopter one way or the other and that's its control scheme uh like i said quite simple um yeah it's it is yeah i think it's like basically conservation of angular momentum um thank you so much for the membership uh did it land yet says michael yes it did about an hour ago it safely we received data back that it safely touched down everything is fantastic um we're waiting to see if they're going to give us any more updates otherwise i'm probably going to tune out here uh and keep working on things here um but yeah the um at this point we might just be seeing updates on twitter i kind of thought they'd keep streaming here for a little while longer and i hope that we start to see more video uh and data come back so i will be sticking around for a little bit longer but i'll get through the rest of your guys's um try to get catch up on some of your super chats again sorry that i will be missing some of them unfortunately all these large live streams i just can't keep up with you guys um from uh carolina uh jess is a huge fan and got me into space stuff please tell her uh tell her off for not putting items back in their place at costco um well jess you need to put stuff back in your place at costco thank you carolina and jess for saying hi uh rob hawk thank you so much um michael kropski you are doing a wonderful job for all of us passionate about space engineering i'm waiting for for next movies greetings from poland you'll have to wait a little bit longer but i hope that i can get some new videos out very soon um i promise it should be uh i think you guys will like this one a lot um tim kulian uh cool and nan says hi tim i'm also a tim from iowa i teach material sciences and engineering iowa state university hit me up with your materials questions awesome coverage awesome channel that's awesome tim yeah i um my dad went to iowa state for two years and then went to uni for two years my sister went to iowa state also for about six months so that's awesome very cool um d-m-e-n-a-m-d thanks tim your channel is the is absolutely the best well thank you so much i'm sorry that it hasn't been very active in the last uh since sn9 basically uh but we're we're working on uh on as much stuff as physically possible uh to plaque if it had crashed on mars what would nasa have done with all the personnel allocated to this mission that's a great question actually i yeah i don't know there would likely i don't know actually i don't i don't know what that would look like i don't know if people get laid off or move to other you know because you can only move so many people to so many things um i don't know if they would yeah i don't know if anyone has any experience with that i would love to know um um yeah okay so let's i'll keep going here i'm alex g thanks for the coverage tim thank you very much alex g um tanner how far is perseverance from opportunity could they eventually drive over to and clear off solar panels if they get to get operational again um perseverance is doesn't really have any way to to clear off any other rovers i don't think it has like it doesn't have a brusher tool or anything on it just scratch the crap it can take its main like master its main arm scratch the crap out of the solar panels if it wants to but it doesn't have any way to uh to gently you know brush it off um and that that really would just even if it's relatively close don't forget um curiosity traveling relatively quickly has only done about um 30 or 40 kilometers on the surface of mars after over 10 years so um they are not that close to each other they wouldn't it would not physically even if it drove straight there with no problems at all it would never i don't even know how close it is but it just would never uh be able to do that so yeah i'm keith um you've spoken on the work the stress and mental health at times please remember there are thousands of us who you not only educate and entertain but um to whom you mean the world and beyond well thank you very much keith um yeah i appreciate that like i said this last month has been about as stressful as it gets i think it's been some pretty extreme circumstances um down here with again with a car accident and an uninsured motorist and all that stuff um and then between that and then obviously now trying to get a studio space down here having a pipe burst and then no power and below freezing temperatures uh it's just not been the easiest month but that's okay um it's everything will get better you know everything i and of course i actually had a feeling the other day i was driving um around and seeing so many restaurants closed and i had a part of my brain had a compartmentalized am i feeling sad that this restaurant is closed because of covid because it doesn't have electricity because it's below free like what reason do i have that i'm like having to be sad for right now it's just really weird it's this really weird um like mental gymnastics at this point almost just to try to like remember like oh yeah there's like three different crises almost that we're working through at the same time right now so things are getting better though i think you know i i'm quite hopeful that power and everything will be restored to normal um relatively soon and um and i'm quite feeling hopeful about the vaccines and the vaccinations and the pandemic coming i'm feeling hopeful that we're getting closer to um more of an end in sight or at least some good news where life can uh have some semblance of normalcy in the relatively near future so things will get better and um yeah um all right let's keep going here from brian wow thank you so much brian uh brilliant streams thanks for doing that well thank you so much for tuning in um listening to me rant about things um this is definitely outside of my normal wheelhouse as you may know brian although you know the video that i made about curiosity versus perseverance definitely taught me uh quite a bit about the two vehicles but um yeah i i i've kind of at this point really become an expert more in space flight and when it comes to planetary science and astrophysics and stuff like that i definitely don't know nearly as much so um yeah so thank you very much brian that really means a lot your support that is very generous so thank you um dj spy um thank god we didn't do a pointy end or logo letters up check on your microphone yes uh you're right i do mount a sure microphone on a low mounted stand so you don't have a stand coming in uh from the top so uh sorry for those of you that are ocd and reading assure logo upside down it's actually the way that i've always done the sm7b i know it's backwards but it uh yeah it actually is pointy end up so ish pointy is to end up uh uh ryukachu uh missed my earlier super chat but do a video on the viper moon mission i'm with nasa making it also krispy kreme mars donut today well thank you for for re-responding again um yeah viper moon mission i will definitely do a video i need to do a video about a lot of the like clips missions and stuff um but viper i'm excited to learn more about that'd be awesome to talk about some of the upcoming moon missions because there are quite a few in the artemis program brent thank you so much cheers uh michael busby if life is confirmed on mars even microbial where does your brain go on that my brain just gets excited that we have new data and new science to comb over and hopefully help understand our place amongst the stars understand life and how life forms and how life continues um you know i think i personally i believe that the odds of us being alone in the universe or at least the only life form in the universe are um like virtually impossible i'll never say zero but like point zero zero zero times fifty thousand uh one you know like i think the odds are so much more in the favor that we are not the only living organisms in the entire universe and granted our you know our sample size so far is basically the earth and the moon um and you know little things here and there from some comets and some asteroids um but you know and having observed you know having rovers observe some samples on mars and stuff like that but you know if we actually were to directly observe some form of life on mars uh it would be huge it would even just to know what does life look like what does life you know you know our conception of what life is right now is is limited to our data set so seeing life live in in other extreme circumstances is it anything related to the life here on earth is it having the same mechanical functions as life on earth like what what does that look like what does that um yeah i mean it's just crazy to think about so where does my brain go with that it's just pure excitement and i can't wait to to put the help put the puzzle pieces together because that's kind of all really that's all science is it's just a giant puzzle and you're kind of taking little pieces and starting to put things together you know with this big giant question and um what you know one of my favorite things about the science about scientific literacy and using the scientific method is that you don't know you come with ideas and then you're basically trying to disprove yourself or try to come up with evidence to substantiate your claims you're basically all great claims require great evidence and you're constantly trying to disprove yourself or have others your peer review um do the same types of research and try to prove you wrong it's a certain humility of like here's my theory i think there might be life outside of earth okay cool that's a nice hypothesis let's go and actually try and observe directly life forms somewhere else so far we've been trying and so far we have not proven that hypothesis correct um we definitely thought you know a lot of people thought there could be life on mars so far that has not proven to be the case we have seen some of the organic trace molecules uh specifically using curiosity actually found a lot of form a lot of signs that there could have been life on mars at one point um but you know yeah for now we have no direct observation so um yeah hopefully that helps answer that question but it's it'd be really exciting um from uh uh janith says uh what will happen if you just carry some water and dump it on mars even say a few milliliters so a great question um i i'm pretty sure mars is is too thin of atmosphere you'd likely have just a phase change almost immediately because it's so such thin atmosphere but also it's it's most of mars is below freezing so it'd likely just turn and um um would have turned into um turned into ice of some kind and boil off yeah it actually it would actually boil off yeah because of the um the temperature or i mean because of the thin atmosphere martin says we we love your work man sending regards and um chechi is short for oh for the czech republic well i did not know that well thank you for teaching me some geography there martin i really appreciate that um thank you antonio for the membership thank you laura for the membership thank you um asco for appreciating my use of the word yeet uh michael thanks for the membership and nikola don't forget if you guys are members or and or patreon supporters uh you'll get exclusive live streams so i will be streaming uh once studio b is kind of up and running the first thing i'll probably do once it's for sure in an operational state will be stream there for patreon supporters so if you guys do want to gain access to some exclusive live streams where you can have a little more one-on-one get a little bit of behind the scenes and just to kind of help um get answers question questions answered and uh and just kind of have a more casual conversation um consider becoming a member or a patreon supporter patreon actually if you if your goal is to support what i do consider becoming a patreon supporter uh because patreon doesn't youtube memberships take and super chats take 30 percent of revenue so um yeah if you patreon is definitely has more integrations as well so patreon.com everydayastronaut i hope to see you guys in some upcoming exclusive live streams james royal there is a krispy kreme in brownsville i did not know that i don't know if they have power but that is crazy um musical wolves thank you so much nearest krispy kreme was three hours away i spent seven hours due to traffic to get the krispy kreme mars donut it was very messy got back we got back uh that is amazing that is some serious dedication musical wolves i can't believe you did that wow wow from yellowstone all the way to i don't even know what your closest city is to yellowstone but that's some dedication that's crazy um jj this was better than watching the moon landing in 1969 really appreciate the great work you do on your videos well thank you very much jj i would have a hard time believing that this is better coverage than the moon landing because that is still the most historic event um in the world so again i'm gonna see if there's if there's something else that nasa's showing that we can put in the background because right now this is and sorry that you're looking at just a horrid uh uh webcam here give me one second here i'm just gonna look and see if we have something else um discord is there something else that we could be watching that's not just um i feel like they're kind of done uh so at this point yeah we'll probably just wait and see if we get any cool updates from nasa um but uh meanwhile i'm gonna work on trying to get um out of here too but i do love i do wanna show you guys this real quick um wow that is awesome that it's tweeted officially the first images safe on mars that is so cool here look at this guys um yeah make sure you're following nasa's perseverance mars rover for some updates that is so cool yeah i love seeing that that's a good sign so um so i'm oh man i'm sorry guys i can't keep up with you still um thank you very much goose fam i really appreciate that um and again to all the members like steven butler um let's see uh i'm trying to i'm trying to get through a couple more of you guys but i'm gonna work on getting out of here uh before it gets dark here which is starting to do in the next hour because again power is quite limited so we have to kind of do some things during daylight hours just to uh to be able to you know do normal things so let's see this is from mike and marilyn warren could nasa use the prop watch from ingenuity to clear solar panels of dust and perseverance um again perseverance doesn't have any solar panels perseverance only has a nuclear thermal generator so it doesn't have any any consideration at all for solar there is the only solar panels in this entire mission are actually on the ingenuity helicopter so again likely when it spins up its rotors it will probably free and you know clear up a lot of the dust that could be collected on the solar panel so um yeah this is from um from wow from um let's see from als auto and appliance thank you so much for all you do on your channel and top quality coverage also no uh no need to mention i wanted to donate in honor of my father cecil who passed away on saturday wow oh man so sorry to hear about your father's pasting but uh yeah cheers to cecil i mean that's uh thanks for spending time with us and hopefully um yeah uh hopefully this was a bright moment for you today and your family to maybe be able to kind of tune out for a little bit um but yeah i'm really sorry to hear your father's passing but thank you so much for saying hi um and and stay tuned because there are a lot more uh things to be excited about and to look forward to in the future um things that i know will probably make your your father proud so yeah um thank you so much for saying hi uh marcus thank you for the membership and nancy um i think i want to end this here um from this um from in indeterminate um i don't think we have an actual date um uh a date on when the ingenuity will take its first flight um yet um in discord there is some talk that the solar panel is on top of the rotors but again there will be airflow moving a lot in that area obviously as the rotors are spinning you know there will be airflow moving straight through it's not like the airflow starts at the rotors the airflow will actually be you know you'll create these vortexes and just because there will be some airflow around i'm guessing that would help clear off the solar panels um a little bit but uh we will see we will see um yeah so it has it only has like a two minute of flight time and it has and it's planned to only fly a couple times anyway so um who knows but then again it is jpl and they'll say something's going in the last three months in the last 10 years you know so who knows how many times and what ingenuity helicopter will look like on the surface of mars but it will be really really really um fun to see so hopefully the images from the helicopter are coming back i hope that it can fly over uh perseverance and get some awesome aerial images it's just it's something to be really excited about uh i can't wait so again if you guys need to learn more about this stuff don't forget i do

here so um if you guys want to learn more about what exactly happened today go to everydayastronaut.com and you'll see that there is the mars 2020 um right here mars 2020. i wonder if the post launch review should now be the perseverance but yeah here's the person some run downs on what we've got so far and they'll keep this up to date um with with certain things uh all the here's all the instruments that it took to mars um an awesome article so if you guys want to learn more here too as well uh check out our post launch review because this was of course at one point launched on a rocket which is kind of what i tend to focus on so this is a post-launch review of the mars 2020 mission which of course is perseverance and ingenuity and it is awesome so um everyone say thank you to flows for for working on that um all right guys so um i'm gonna work on heading out of here guys thank you so much um one more question from musical wolves when loading let's see here when uh when loading locks onto starship how is spacex able to prevent air bubbles from forming or are air bubbles in locks tanks not that big of a deal so um airbus so locks because it's if you take let me think okay so so basically first you purge the vehicle with nitrogen so it's all an inert gas then you start loading it up with liquid with liquid um liquid oxygen and liquid methane and it's because it's so cold it comes in as a liquid you're literally pouring it just like you would gasoline right and then um or or petrol or diesel or however you want to say it um and then as you fill it you basically maintain tank pressure by allowing certain uh you know some of the backfilled nitrogen to to vent out or the ambient pressure to um to vent out um liquid oxygen as it warms up will automatically turn into a gas it will turn into its gaseous state and it will expand so you're basically constantly venting out gas bubbles and then of course because of buoyancy the more dense liquid will stay on the bottom and the gaseous portions of either nitrogen or helium or uh you know the gaseous methane or gaseous liquid oxygen will stay on top and then just to maintain pressure they just vented out so there really aren't like these bubbles or anything that you might think of um in like a bathtub with a solution or something and things you have to worry about in that end so um yeah so stay tuned guys like i said i will have some awesome videos coming up and hopefully some more live streams and hopefully be streaming from studio b here um from our studio b here sometime next week fingers crossed we're working on a lot of really exciting stuff so thank you guys so much for tuning in and watching with me it really means a lot to me that you guys are uh watch this with me that just is is

atlas five so um awesome work love seeing this i cannot wait to see more from the perseverance rover and uh cheers to mars 2020. all right guys uh thank you so much again for hanging out with me
