stream I feel like it's it's been a couple it's been five or six weeks or something that have done a live stream besides some supporter live streams but this is one that definitely I'm excited that I'm able to stream this because this is history we are about to witness history of one of in my opinion this actually is like one of the most iconic Rockets um it is a rocket that I've only probably watched I don't know five or six you know live streams live I never gotta catch it in person unfortunately almost did uh it launched the James Webb Space Telescope the Orion 5 is going to be taking off for the last time here in T minus 30 minutes and just a little heads Up Normally we have a little like info bar thing right here that will you know tell you about that and unfortunately for whatever reason literally it was working one hour ago we totally had it all tested and ready and of course like clockwork as everything as uh you know tends to happen in my life at all times like this it stopped working literally like five minutes before I go live so hopefully we'll we're working on in the background trying to get it fixed and hopefully it might pop up and give you an update on times but we are 26 minutes away from seeing this Beast fly so that being said of course when you guys have any questions about uh you know what this Rocket's going to be doing what's the payload we saw on Discord um acts in our Discord Channel asked about five minutes ago uh what's you know what's the payload and I linked a little website called everydayastron.com don't forget anytime like it's we when we try to make this website is as easy for you guys to get those questions of when when where what why without like any blurbs just the data so go to everydayastron.com click on upcoming launches and you can read through our pre-launch previews so this is uh the Syracuse 4B and Heinrich Hertz H2 set um this is and this is all on the Ariane 5 ECA plus so this is taking off today July 5th happy uh day after Fourth of July for those of you in the United States uh gonna be taking off here like I said in about 25 minutes uh 22 UTC the mission name is VA 261 Syracuse 4B and Heinrich Hertz H2 set which rocket provider is launching this this is of course Ariane space makes the Orion 5 rocket the customer who's paying for this it's the French armed forces and German Federal Ministry of economics and technology or BMW I don't probably get it too confused with BMW um the car manufacturer and airplane and engine manufacturer the rocket is Ariane 5 ECA plus this is the the ultimate you know the the final iteration of this rocket the launch location is of course this is the only place the rn5 launches from el3 the from the Guyana Space Center down in French Guiana France very close to the equator takes full advantage of the Earth's rotation um and this is also what I what I love about talking about this is that's actually a video we're almost we're about ah we're making good progress I don't I'm not gonna say we're almost done but we're making good progress on a video kind of helping you just you know differentiate between space and orbit uh you know what those different things are and what and how they how they're different you know how you really get into orbit um the whole like going sideways thing really fast and all that stuff but we're using that as kind of a precursor video because the next one I'm going to talk about is like why don't more Rockets launch from the equator so it's going to be a pretty fun Deep dive it's going to talk about that and a whole host of topics and I think you guys will absolutely love that one um and it's going to answer a ton of questions that I see very commonly asked so uh the uh the payload mess this thing's pretty darn heavy 69.50 kilograms so 6.9 tons heading out to geostationary transfer orbit for those of you that know geostationary transfer Orbit's quite a you know it's quite a hefty thing they're going to launch it uh have the highest point the apogee go all the way out actually slightly Beyond geostationary orbit and then the spacecraft will the spacecrafts will actually have to raise their orbit to put themselves into that geostationary orbit but uh that's a pretty hefty geostationary satellite which makes sense around 5 is a hefty rocket um so yeah they're heading out to geostationary transfer but will they be attempt to recover the first stage no this is not technically a capability of Arion space although the boosters originally on the rn5 were recovered but not for purposes of they didn't recover them uh they recovered them under parachutes kind of similar to the Space Shuttle how the space shuttle had the solid rocket boosters that were recovered um via parachute it was similar to that one the first launch Maybe be two launches and they didn't do it for reusability they did it to see how the boosters fared and just kind of for engineering validations and things like that so um but it's not a capability anything they ended up looking into for any kind of reusability or anything so the boosters uh and so you kind of I don't know how if you want to consider that the first stage but definitely the boosters and for sure the core stage the center part are all going to be crashing into the ocean uh the booster or the course I don't know if it'll be going into the Atlantic but it will be crashing uh will they be time to recall their fairings nope not a capability of this rocket and so far not a capability of anything other than Falcon 9 and Falcon heavy so these are new fairings uh the this will be the 296th mission for Arion space ever that's getting pretty good this is the second mission for Aion space in 2023 the 117th Ariane 5 Mission and of course the last one the second Ariane 5 launch of 2023 and the 91st orbital launch attempt of the year which is amazing we're seeing far more launches than uh than what we've ever seen in the past and of course if you guys want to know anything more about this rocket about this Mission about anything else you can click on the pre-launch preview here again everydayastronaut.com read through it uh you can learn more about what Syracuse B is which is uh the second of two of the of two military communication satellites uh built by by Tally's Delaney I don't quite remember how to exactly say that right uh but it's it's not that as well as the H2 set which is a brand new communication satellite for Germany so um yeah very very cool stuff if you want to read more about that we talk about awesome what is the Arion 5 what are what are the boosters the main stage here running on the Volcan the Volcan two um by the way if you guys haven't watched I'm gonna shout I'm gonna shout this out right now for any of you guys that are watching that haven't seen it I did a video um a few months ago uh here let me let me find it and then I'm gonna pull it up for you guys um it is a video about man this is so weird for some reason the YouTube stream is being funky for me but I'm gonna I'm gonna find it here quick and then I'm gonna show you guys this video it's actually I I love it um every day astronaut if you search everyday astronaut that's me um what did I do uh Ariane Issa Aryan I don't know we'll just type Isa Ariane and you will find a video it doesn't even know that's not good even searching it I didn't even hardly find it um so this is this is the video I'm talking about a deep dive tour inside rocket engines and we look at the Viking 2 and the Volcan one engine and I you know these are engines that I really didn't know much about before I went to this Museum the East Tech Museum um outside or what was it called the space Expo Center outside of East Tech the Issa Center um in the Netherlands and it's a really fun video because I'm just walking through kind of you know not blindly obviously but like without knowing a lot of data on these engines and just trying to figure out all of the different things like how are they cooled what engine Cycles are they and and they have a Volcan one there and is really fun to be able to dive into it I would highly recommend watching this video If you haven't yet I promise it's just one of those fun like learning things and it's relatively short for an everyday astronaut video at just 26 quick little minutes nice and easy um all right I'm gonna cut to this trying to get uh back into the stream here because it is live for whatever reason it's been a little wonky for me but I'm gonna start pulling it up here for you guys um feel free to ask questions you know as always if if there's a good question I see it in chat our mods will pull into the queue the comment section is working on our stream but that's the only thing that's for some reason like I said the overlay is not actually working um so let me get that all pulled up for you guys here and I'll start trying to pull up some questions and answer them when I think it's an appropriate time to do so but that said let's listen in here very resilient and it can resist even the most extreme jamming and that's exactly what the military need for their operations let's take a closer look at Syracuse for will be and that seems like a perfect time to answer some of your questions because normally they have music that's copyrighted okay so uh this is uh a great question here from Eric souter Eric uh supporter of the channel as well I believe and uh see that name often Eric thank you for for the good question here um asking anything after Ariana five yeah there the Ariane 6 should have been ready by now it's darn close to launching um really hoping there's not a big overlap between the Ariane 5 and Ariane 6. um I don't know what the exact latest is but the um last the last that I saw it was something like um um they're still hoping for by the end of this year but I don't know if something has changed recently by the way hang on I'm gonna put a little uh I gotta put a little thingy in here and fix this I think our overlay is going to be working now let me try um okay hopefully hopefully it comes back and we do have our overlays for you guys um but I'll let you know if they are okay the next question here um yeah I absolutely this is the same sentiment you know um rum kit boy the rn5 has been pretty darn reliable it's had a few you know early on it had some some failures and then a handful of years ago I don't remember when that was four or five years ago it did suffer a partial failure um you know it's kind of had it's it's done well and it it's really performed like you know when it launched the uh James Webster Space Telescope is arguably the most expensive single launch in history and um yeah it's just crazy to think that you know it's delivered on on one of the craziest Rockets or one of the craziest payloads ever okay let me see if I can um let me see if I can refresh this and get this working again maybe we're going to yeah we're getting there cool okay hopefully that that works out and uh hopefully hopefully yeah it looks a little like we're missing a few things or whatever but it's okay we'll get it figured out at least you have a t0 clock here for us okay um yes Paul exactly like we're talking about there there was an explosion on the was it the very first one that had the integrated problem that the integer where is like calculating something wrong and it just basically made the rocket go huh and it was absolutely wild um yeah uh let's see here does the rn5 have different configurations like the atlas 5 does um not like it's not oh hold on preparing these two satellites for their Journey today and of course the Ariane 5 Launcher we call this preparation progress but process the launch campaign either they're talking about a the current okay sorry um but yeah there really aren't like huge different configurations for the most part it's going to be the same Center core the same boosters um you can ride with they can have two full-size satellites kind of ride sharing almost with this really interesting payload adapter thing it's like a it's almost like a cup sitting you know upside down inside that fairing that has a satellite underneath it and a satellite on top so they can deploy the first satellite release that cup thing and then deploy a second satellite um yeah okay cool it looks like our overlays are working perfectly now thank you so much to our everyone in in uh in chat right now to say thank you to Colton and Mary Liz and Jeffrey and all those that just say thanks everyday astronaut team for helping get those overlays back up and running uh I just having a t-zero clock is always a good thing um let's see even though ours does appear to be quite ahead hmm I'm gonna move this because there actually is one now that I see I wasn't even paying any attention and now that I see there is actually one behind my face I'm gonna move that out of the way real quick here and then uh hopefully Mary Liz can line that up and we'll have a nice clean t0 time and the funny thing about this rocket by the way at t0 it will sit there for like eight seconds and it always feels like nail biting like is it still going and that's just as they ramp up that Volcan 2 engine it just sits there it's a sustainer engine it gets up to full power and then they light the solid rocket boosters it is crazy um let's see this is from Robert uh Robert Frank thank you so much for the Super Chat have you started on dear moon training if so how is that going if not do you know possibly when uh I I can't really talk about exact timelines on things but I can say that we have not begun um any official training yet but I think we're probably getting pretty close but honestly a lot of you know dear Moon's going to be relying on um the progress of Starship so they're not going to solidify training programs until the Rockets uh more solidified as well so it's it's uh yeah it's getting there and I'm really excited I think that's going to be a a huge uh you know huge part of my life that's gonna be like holy crap and it'll feel very different and real when it starts to happen um one thing that I'm doing on my own personal account is by the end of August I'm going to finish my pilot's license um I'm 30 some hours into my my private pilot's license already most of those hours are over 10 years old but that is something that I've wanted to finish for a long time and I actually think it'll be really good and healthy to get into that Groove before training so that's something I'm going to be doing kind of for myself and for fun and as a challenge obviously I've seen this you know Scott maley's done it in the last year and it's like and I have hung out with some of the you know the fighter pilots and stuff from Polaris and Jared eisenmann seeing all those guys and it's just like oh man I I gotta do this I have to finish my pilot's license um so yeah it it I definitely am excited for that um let's see here um this is uh yeah Mars 2028 and this is a true statement from Mars 2028 um in less than an hour Europe will lose independent access to space for at least the next six months yeah I mean it's it's interesting though even even now with the Ariane 5 there's been times where there's been tensions with French Guiana and it's actually been hard um and that's more of a local you know obviously French Guyana is a French territory but there's still politics in play that have even prevented launching from happening down there but that you know any launch site could have those problems so I'm not saying that's you know not something inherent to this but like it is it's all all the eggs have been in one basket for a long time is basically what I'm saying and it's going to be good when there's some private you know we have RFA we've got um orbex and a handful of other rocket companies working on getting um at least you know polar orbit capable launches launching from European soil which would be really really cool um she started 11 hours ago and there's a whole succession of operations that happens during that time coming up now to an important moment which is the final weather check of course all lights on the weather here in the European Spaceport um yesterday we did have a delay delayed launch we can control most things but of course the weather's down to Mother Nature isn't it yes exactly but what we typically check is um the wind at high altitude the wind around the launch pad and the risk of lightning that could damage the electronics during the launch rain is not so much of a problem and that's a good thing because it's been raining quite a lot in the past days um we are in a tropical weather here in French Guyana and we are actually in between the rainy and the dry season yes it's not cool the Amazon rainforest for nothing but it's actually a very good place for launching Rockets from isn't it oh yes it's an ideal location for launching satellites into space in front of Guyana there is no big tropical storm no hurricane no earthquake and more importantly we are located five degree north of the equator which give us a maximum slingshot effect given by the rotation of the earth French Guyana has also an amazing wildlife and sometimes we see some animals wandering around the preparation buildings but let's say that in more than 40 Years of activity nature and Technology have learned to live in harmony here in French Guyana oh that's very very true we see some beautiful animals here I actually saw recently a sloth crawling very slowly across the main road I should I should point out for a second that yes the YouTube stream that they're providing is occasionally glitching out um and there's not anything I can do about that obviously um yeah I've got all the patients in the world for that I understand how hard it is to to stream uh cleanly I wanted to answer this one this is a great question from Merrick Stern when was the first Ariane 5 launch the first Aryan 5 launch was in 1996 um and then uh I think it was like June someone fact checked me I think I feel like I read that a minute ago I don't remember um but the boosters and engines so the boosters on the side are solid rocket boosters and they're pretty darn close in scale and power output I mean not exactly but similar to the space shuttle's solid rocket boosters on the sides there um I love that they taper inward I think that's a beautiful design feature it's similar to you guys know I love my old Soviet rockets and of course the the soyuz kind of tapers in like that the proton has tapers in like that for the nose cones I always use those when I'm building rockets and Kerbal Space Program I just think it's cool to attach it there instead of having like a freestanding nose cone um the center core is hydrogen and it uses the Volcan 2 engine which is an open cycle hydrogen hydrolux engine so it's actually uh so as far as uh hydrogen engines go it's not super efficient but it's still it's great though I mean still that obviously gets the job done it's a very reliable engine um and what the what it does is it lights at the beginning just like very similar to SLS how SLS is hydrogen power it has you know relatively efficient hydrogen engines but in order to get that big heavy tank because don't forget hydrogen is super sparse it's not dense at all so the tanks need to be six times bigger than an average tank for you know say rp1 or methylocks and so the tanks and the rocket just is monstrous gets very large so to get it off the ground in the first place you have to use big powerful solid rocket boosters and then those uh you know will literally lift the center core while it's running so together they'll all provide a lot of thrust and of course the center core is helping at the beginning but it's very marginal compared to everything else and by the time the booster is detached it's burned through enough fuel uh to be able to to continue on they're doing something here better and the synchronized sequence has begun Raymond Boyce the range operations manager or DDO in French has announced it and Aaron 5 Standing Tall for a sunset liftoff what's happening in the synchronized sequence so there is a complex set of operations leading us to the launch and giving more and more autonomy to the rocket so just to name a few we have the topping up and the pressurization of the tanks of the main stage and of the upper stage at the onboard computer will receive the exact time for liftoff it's located right here and that's the brain of the rocket if you want I'm at one minute to launch the power supply will switch from the ground to the rocket the launch we will see it only when the two lateral boosters ignites believe me this is going to be spectacular she's had a fantastic career let's have a little look at some of her highlights was highlight reel running the background light continue to answer I'll finish up that other question the upper stage by the way we talked about it the core stage being hydrogen the boosters being solid rocket boosters the upper stage is also using hydrogen so hydrolux so liquid hydrogen liquid oxygen um it's it's offers the highest potential for efficiency but at the cost of being again not dense at all so the Rockets are just physically very large so this is almost like a baby SLS rocket it has a very similar configuration where it's got solid rocket boosters to get the core and the rocket off the ground as we'll see in this beautiful montage I'm sure a few times and then hydrogen throughout the rest of it so quite efficient and I just looked it up here I was curious what the upper stage uh how efficient the upper stage engine is and it's um the hm7b it's regeneratively cooled gas generator so it's open cycle so it's normally you know kind of consider that oh this is a beautiful shot dang it I wanted to see more of that um but it's it's pretty impressive it actually is 444 seconds of specific impulse which that's pretty fantastic for open cycle um because open cycle don't forget you're dumping some of your exhaust some of the the gas or the propellant you're dumping it completely overboard it's not aiding in the direct thrust of the rocket so um it's harder to achieve extremely high efficient rocket engines when it's open cycle so hitting 444 you know we you only get about 10 more seconds when you do like an expander cycle um like the rl10b2 uh which is gets I believe it's like 454 or 460-ish or something like that if I remember right off the top of my head might get it's 464. I don't remember it's it's not like you know it's not where it gets 20 better or something it's it's just marginally better um yeah let's uh let's keep going here with a few more questions look at how I I hate solid rocker boosters and I love solid rocket boosters um I just think they're primitive but at the same time it is I kind of enjoy that you it makes such an obvious streak and unfortunately that streak is high of Highly pollutant um but it is just fun to be able to see exactly where the Rocket's going um but yeah I'm I'm ready for us to move away from those in the in the future uh Max E I'm one of his max Evans glad to see you back on stream and hope to see you back at the cape soon watching from KSC awesome thanks for saying hi Max I really appreciate it um and um Absol absolute uh celebrating 10 months of membership thank you so much ooh ooh ooh I have a fun announcement for um first it'll be for all supporters you all gain access to what I'm about to talk about here in a second um if so if you support on Twitter Youtube or patreon um get ready I'll be sending a link out probably right after the streams or later tonight um we are you need to take out a survey we're planning and working on trying to get everything ready for the first live Astro Awards next year so in 2024 we're going to do it's going to be a small uh mini conference with speakers and tons of fun live stuff very public facing it's going to be meant to bring you the public and US enthusiasts together it's not focused on the industry like you know some of the other uh conventions out there you know like um like what's it called uh IAC and you know space Symposium things that are a lot more focused on the industry professionals this this is focused on the public on Space enthusiasts and we're getting some data from you guys and getting your opinions on what types of things you want to see all that stuff so oh that's um okay cool they're they're I'm gonna listen in here and shut up but just be aware if you are a supporter look for that and then we'll do that pull again uh with the general public here next week so get ready for that as well um I'm really excited for a lot of hard work's already going into it so I'm gonna shut up and I'm gonna listen because we're down to T minus one minute 45 seconds this will happen seven seconds later so we won't see the launcher moving during these seven seconds this is just a little warm-up before the very last Aryan 5 rocket takes off to the sky can you imagine Katie that next time the satellites will see the outer World it will be in the emptiness of space one minute and 17 seconds now minutes enjoy the show here we go who's ready to watch History everybody send uh your final thoughts and prayers and good luck well wishes we are about to see the last Ariane 5 launch ever oh that's a cool shot of the crowd and T minus 45 seconds so get ready and I'll stick around for a little bit afterwards to answer questions and hopefully uh hopefully just celebrate with you guys and and we'll get through as many questions as we can and uh yeah I can't wait here we go T-minus 30 seconds I think I just saw a little uh remember it'll sit here for a long time so it's okay here we go yes what a beautiful rocket it just leaps off the pad so crazy fast here comes the sound nominal metabolism normal Syracuse 4B and Heinrich Hertz satellite blazing a trail on board the last ever Ariane 5 across the equatorial skies and we can hear the rumble okay as she flies over it's it's very impressive and we are you know 11 kilometers from the pattern the delay of the preparation is a bit amazing it's we can just kind of get tired of it and we have a very good view of the launcher nominal he's telling us that the trajectory is nominal everything is going a plan one minute and 56 seconds into the launch fantastic view of Ariane 5. well we have a very good view I'm sure we will see the booster separation nominal so the the proportion is working perfectly nominally as we say in the space Jacob and here we will see a booster separation we have confirmation from the range operations manager yes that's absolutely amazing there's two boosters on the right and the left being jettisoned the white dot in the middle the Vulcan engine so they are providing 90 percent of the overall thrust and so they have been jettisoned there are 240 tons each the launcher on the ground was 771 tons and we don't need them anymore everybody is completely nominal so next step is the separation of the fairing that's coming up trajectory on the left hand side is the planned route for the vehicle and separation there of the fairing is what it looks like I did want to point out the animation we're seeing is just an animation I don't believe it's tracked okay nominal 117 kilometers above the ground when we separated the fairing so we so I I uh correct me if I'm I'm wrong but I'm pretty sure it's a pre uh made animation so if something is off nominal we wouldn't actually see it in the animation it's not like um when Ula launches and goes to kind of an animation that's actually taking real-time Telemetry and showing you a graphic of what's happening I don't believe uh Aryan space does that I'm pretty sure this is all just a pre-made thing but I did want to point out um right below the main satellite on top you see what I kind of described as a cup you know it's almost like a make sure there's nothing in here like an upside down cup there's another satellite inside there so first we'll deploy the top satellite then they'll deploy the payload adapter which has another satellite inside of it so it's a really cool way to get two full-size satellites you know the the fairing of the rn5 is absolutely enormous so um it's easy for them to fit two full-size satellites inside there everything's still looking great and by the way the booster runs for a long time I think it's nearly it's like nine minutes or something ridiculous so we still have rev t plus like you know almost five minutes the the core of stage will still be running for like four more minutes it's absolutely incredible but let's listen to what they're saying again see Heinrich Hertz satellite for the first time he said that they were gonna see space the next time they saw the outside world well now Henry hurts can see space that's the that's the case for the upper passengers the lower passenger Syracuse Bobby needs to wait a minute a little longer in order to meet space for the first time what we see is the black structure this is the Dual launch structure called silda so it's used to accommodate the two satellites under a single fairing yep that's what we're talking about it's a very clever piece of Kit because it allows you to attach one satellite at the front and then in the lower birth he's just told us that we have about three minutes roughly right left on the on the main stage so thanks to the Vulcan engine that's the engine of the main stage we are gaining lots of speed right now so in less than two and a half minutes we will go from four to seven kilometers per second which is very fast obviously and this is a huge structure it's a 30 meters high filled with approximately 160 tons of cryogenic properties stored in two different compartments one for liquid oxygen one for liquid hydrogen you definitely don't want to touch it because it's extremely cold it's 100 degrees below zero incredible when you think that the two boosters boosters on the side when they are burning and of course that's just such remarkable feat of human engineering isn't it side by side so everything is going perfectly right now now as I mentioned again the the graphic thing on the right is pre-made you know it's just an animation of what is expected to happen but at the Telemetry here in the top left that is real-time Telemetry telling us that we have now picked up the signal at the ground station in Natal which is on the northeastern coast of Brazil and we're tracking the launcher using Telemetry yeah so the launcher sends signals back to Earth all along the flight which are recorded by a network or Telemetry stations so that the teams can make sure that the mission is performing nominally again that's a word that we will hear very often during this flight it's like a really race with one Telemetry station passing the Baton to the next one by the way the trajectory today is a little bit different than usual we will release the telecommunication satellites on an orbit with an inclination and it's also three degrees with respect to the equator instead of six degrees as it's usually the case for this kind of missions so it will be easier for the satellites to reach their final geostationary orbit we were able to do so because we had some remaining performance on the rnn5 and when we have some margin we just give it to the customers and so the first station to pick up the signal was galio here in Kuru now it's natal and then we will have other stations all along the flat path coming up on the next sequence of events separation technique so he's done three very important events there yes so the extension of the main stage engine the successful separation of the main stage from the rest of the launcher and just now the ignition of the upper stage it's super important step because you know there are three engines on the Rockets four engines sorry three are ignited on the ground and this is the only one which is ignited in space at 200 and almost 40 kilometers of altitude so it's a very delicate operation and it's imperative that we succeed in order to continue the mission so we should point out too you know I have that video about how you start a rocket engine and starting in space is substantially you know it has a lot more uh things to overcome problems to overcome compared to lighting an engine on the ground you know one of the biggest things about lighting an engine on the ground is if it doesn't look good you turn it off and the Rocket's still on the ground you don't get a second chance uh when it's in space if something doesn't go right you can't bring it back down be like well let's fix that engine and launch it again it's like if it doesn't light that thing's going to re-enter and burn up on re-entry so the upper stage engine is even more difficult and so the the another big challenge is not only getting like you know the engine up and running and spinning and cryogenically you know are thermally prepared for all the credit propellants inside of it but another big thing is it actually needs to settle all the propellant because as soon as that booster well done oh my gosh I was about to use a mug again when I've got a rocket here okay so as soon as the engine well they're going to this so I guess I'll go like this so you guys can see why are they doing this in the middle of the launch broadcast okay good we do have some tele training stuff too okay so as soon as imagine these you know are being accelerated ignore the fact that the landing legs are out just ignore that uh the Rocket's accelerating right so all the propellants being pushed down um you know especially near stage cutoffs uh it's gonna be pulling three or four G's of of acceleration maybe five G's depending on the launch profile and that's going to be pushing all the propellant down towards the bottom of the tanks as soon as that engine or engines or whatever the booster engines cut off is going to be coasting you know imagine like if you're jumping up on a trampoline or at the top Arc of a you know a roller coaster or something like that weightlessness feeling so that means all the propellant inside just gonna go and just and blob about right what so what's going to happen is after stage separation even though there's a quick little you know a little a moment of inertia there where it's going to accelerate for just a brief second the second it's done doing that without any other form propulsion it's still more or less just floating so all the propellant inside is going to be uh floating around and if the engine starts in that state it could suck up gas bubbles because they're you know the tanks are still back pressure filled with gas so they're liquid propellants but they use uh gassy as either nitrogen High helium or gaseous versions of uh you know gaseous hydrogen and or gaseous oxygen or whatever in the tanks depending on the rocket and they need to settle that so they might have to use olig thrusters or some other form of propulsion to accelerate it a little bit before they light the main engine so it's all of these like there's so many things that go on just for that one very brief moment of time so lighting an upper stage engine is extremely vital and very difficult so um it's a big milestone it's been fantastic so far the hm7b on the upper stage looks like it's running absolutely nominally following Along on that uh trajectory perfectly so that's why I kind of talk about that and give you some of that perspective it's still going great um yeah I've wanted to actually answer just a few more guys questions here and then I'm actually gonna head out I was really I'm really glad this launched right at five o'clock because I'm trying to do dinner with my family which is a a traditional about once once a week I try to grab dinner with my with my family so um let's see here this okay um this is just I I'm just reading what this person says and I'll comment on it James says I don't think Ariane 6 will last long they need a reusable rocket to start competing um seems that dream they spoke about became reality unfortunately so in in my opinion I I you know there's a lot of concerns about the you know the future of expendable launch Vehicles you know obviously a lot of people are moving into reusable launch Vehicles Ariane space had plans to make um partially reusable components of the Orion 6 including the engine but now they've kind of given up on that um it'll be really interesting this will be um you know a pivotal moment in space flight history when we have new rockets coming online in the early 2020s that are not reusable how many of them will be around at the beginning of the 2030s um we'll just have to find out it's it's hopefully going to be more competitive than the rn5 and the Ariane 5 still has a great place in space flight um the in the industry so want to find out um Kitty thank you so much for 37 months of membership um also Patrick Walls are 46 months of membership these are crazy numbers guys thank you so I didn't even know I had memberships 46 months ago Patrick must have been one of the first people to sign up greetings from Germany can't wait to see you at space Creator day that is correct if you are in Europe if you're watching this and you're a European viewer look up space Creator day I will be going to that I believe it's October 21st so just get ready for that it's going to be amazing and thank you Patrick again for 46 months of membership really appreciate it same with Astro Joe six months um yeah and Jerry wants to know what's going to replace the Ariane 5 as we mentioned the Ariane 6 is the next vehicle in the lineup um oh they're talking about the Ariane 6 right now so maybe on screen we'll see a little bit um talking about the Ariane 6 which is I believe all the components are at the pad so hopefully there's not a huge gap between the two um I have to answer this from corellio of Apollo and yes I'm saying corlev or Corelli of closer it's closer to curlyov than corlev corlev is not the correct way to say it that is just plain wrong it's actually a misinterpretation of how you even spell phonetically than the name so trust me I spent way too much time on this um would I rather fly in the Soviet and one or Aries one um two doomed Rockets I actually think I would probably rather fly on the the RAS one or Aries one because of the fact that it flew was going to fly the Orion capsule so even though it's going to shake you to death because it's riding on a giant SRB at least you'd be roomy while doing it as opposed to being in a tiny tiny tiny spacecraft trying to go to the moon on the N1 just does not seem like a fun idea at all to me so um yeah um and thank you again to uh to pizzek for membership um let's see uh thank you so much to Gramps Izzy for uh the love I appreciate it very much um no way uh this is hilarious Mahler fan going to be riding Ragbrai well certain somebody's going to be riding on Ragbrai too so look for me um any chance of an everyday astronaut cycling Jersey appearing in your store not this year but we're literally working on it believe it or not for next year so stay tuned um Ally from Gravity Coast is has some plans and she's starting to work on that as we speak I can't wait I would I can't wait to have an everyday astronaut in Jersey um to go along with all my other jerseys so yeah hopefully if you see me say hi um let's see Robert wants to stay with a new hot staging Starship that will probably give a human rated stretch of the ability for crew escape that will be good for you I my biggest problem I made a video about this already though is that you're relying on still a cryogenic propulsion upper stage with too low of a Thrust to weight ratio to even lift itself off of the launch pad if it's uh you know a problem with the booster on on launch um I don't I I still would prefer that the crew module would have would have a fully detachable fully uh independent crew launch abort system um want to see when the time comes if they start to integrate that kind of thing or if they have reason to believe that the vehicle is just indeed that robust and reliable um let's see here I'll try to get through as many um what hot sauce when I compare this rocket to Frank thank you for tuning in much appreciated thanks for the tip well Frank uh I made Frank try um if Frank tried to bomb and this rocket is not that nasty um although it is Big solid rocket boosters kind of nasty if you if you walked into the plume of them after launch you'd probably feel like you um are swimming in Da Bomb hot sauce um that's a great question Frank um I'm gonna say this is the Pablo's um Smoky Chipotle no Serrano you know great all-rounder um been around for a long time delicious there you go thanks Frank uh let's see here um why were the rn5 Rockets not certified for human launch I actually don't know the they they were going to they had the um the the Hermes was it um oh man French space guy is probably going to be cringing at all my answers because you know this is a rocket and program that I really have not studied um but it was originally going to be flying humans and that program I forget what it's called um it was canceled basically but I don't remember there there still was something that was going to need to change between the standard iron five and one that was going to fly humans and I don't remember what the the big change was um maybe we'll someone in the chat will remind me that yeah the hurt the Hermes or Hermes shuttle but yeah let's see here um this is from from Jorge saying it'd be amazing to see me at the first launch of the the mirror rocket um will I be listening to Fly Me to the Moon oh man I'm gonna have quite a Time with playlists I need to remind myself what the mirror rocket is um I know I've seen it um which one is this mirror one oh oh yeah is this the Spanish rocket um yeah um I mean maybe we can we can figure something out if you know uh if it works in my schedule who knows maybe we could try to try to do something I probably don't want to cover it live I'm very not into doing that anymore right now I'd much rather like do a dedicated video on it or something um that might be something we could figure out um well that's awesome from a long name here uh celebrating three months of membership hey Tim I remember meeting you down in Starbucks before sn9's launch been a fan for more than a year and love everything you and your team do well thank you so much to I believe it's Artemis yeah Artemis in lead speak thank you so much I really appreciate that um hopefully hopefully I guess you're still a fan and I wasn't a jerk when you met me in real life so thank you for saying hi and thank you for your support oh that'd be funny if someone's like no I met you and now I'm not a fan I unsubscribed um let's see oh awesome uh thank you for tuning in to think I would have missed this if not for the last check on what's on my subscription list thank you for sharing this historic moment you are welcome I am excited uh to be able to have caught it like I said I'm gonna be heading out here relatively shortly um as the rocket is still burning will it be fun to get through the upper stage Burns we have good confirmation of that almost nine kilometers a second already I don't remember to 70 kilometers high no I don't remember what geostation or transfer orbit is I think it's closer to 10 kilometers per second of Delta V to get into that geostationary transfer orbit that elliptical orbit but I don't remember the exact number offhand um and so Joe pipple yeah so it's it's funny because once they light those solid rocket boosters you saw the law the rocket just leaps off the pad like those solid rocket boosters are so strong and so powerful that it just literally goes boom just jumps off the pad the sustainer engine like they mentioned in the live stream it only provides about 10 of the total thrust so it's gonna going to go nowhere while that sustainer engine gets up to speed but they they light it and it goes about seven or eight seconds to fully get up to speed uh and and produce thrust and be validated and then once everything looks good then they commit to launching and the you know the computers will commit to launching and it'll light the solid rocket boosters and away it goes very quickly then um SLS kind of did a similar thing it's just they did it T minus eight and a half seconds they let the rs35s get up to speed once everything's looking good the computer likes what it sees boom it'll light the solid rocket boosters um yeah um hopefully Ariane 6 has cameras on board like Falcon 9 that would be awesome um this uh yeah um I there's still an exclusion zone for pretty much any rocket launch uh at least I believe for these there's an exclusion Zone down the the ocean so that there aren't any uh there's no air or boat traffic in the way um what are my thoughts on hot staging I have no qualms about it I I think hot staging so it's it's a hot Hot Topic right now uh because uh Elon Musk mentioned that they're going to try hot staging the next Starship launch already which is basically where again it's back to you know rocket time here um that's where they while the first stage is still burning they will light this the upper stage while it's attached to the first stage and then it will separate and it can then shut this down if they want to or keep those engines running and do the flip uh it's it's not that unheard of I mean the tightened rocket did in the United States the Soviets did it on the R7 the proton um the N1 although it never got to get to Hot staging um but yeah there's I mean there's a there's a lot of a lot of reasons why hot staging makes sense I am excited to see how it turns out if it doesn't destroy the booster how will you know how it will affect reusability and reusability goals but one of the big things hot staging if you can literally get to your flip sooner imagine when the Rockets traveling it will make up a number 4 000 kilometers an hour away from the launch pad at that point it's pretty well tilted over um you know the longer you coast and wait for the second stage to start before you begin your flip and re-light the more fuel you have to more propellant you have to use in order to get all the way back to the launch site which is something that Starship will do Starship will be returning to the launch site so even those will save seven or eight seconds of coasting away that's a lot of repellent to not have to undo that in the long run so it actually makes a pretty pretty big difference [Music] um let's see here um let's keep going um seven months of membership from Sean Paul Fisher is the esa moving to soyuz launches from French Guiana what's the what's isa's next launch vehicle um pleasure media to the first Falcon heavy launch a lot of people that have uh that I've run into in real life that's awesome ooh they did have a stage cut off though yay pan oh no that is right where the yes so did you confirm that it got successfully cut off that upper stage enrich Earth satellite so really getting now into the next phase of the journey preparing to separate our two satellites from the Mothership right now without the engine we are coasting in the coast phase which we often call the ballistic phase which means I believe that we are traveling without power and we're on trajectory yep we are really awesome studying took everything's looking good I'll answer a few more questions and it looks like we'll be able to see payload appointment and then that's a perfect time for me to get out of here uh which I'm excited about um Louis Rogers says would you mind Milling that rocket we sell these at everydayastronaut.com uh they are metal I I like I always like showing that off because not a lot of like it's a heavy duty beautiful rocket that I'm just it was over it was like 18 months in the making and it's so satisfying like when you click the legs in place and stuff to actually have good you know things that feel good and are of high quality um it was a lot of work that our teams did to to make it an awesome product that I'm super proud of we are in the design phase of our next set of rockets but yeah you can get these at everydayastronaut.com shop um so I don't I don't even have to mail you this one you can just get it yourself so thank you for that um let's see Eric says uh I'm on my way to the to the years I'm not sure what that means Eric but thank you good to see you in here uh we do have some new memberships from Baja truck guy and also Grady Holmes don't forget like I said pay attention we will be doing a survey here um to get your thoughts on our first live Astro Awards and Conference and I want I'm excited to hear from you guys what you guys are looking forward to what you guys want to do what things you want to avoid where you're willing to travel to all of those types of things because even we're at that phase even where we're doing trade studies on like which cities which venues uh type of thing and I'm really the more we plan it the more I'm excited about it uh and it's going to be absolutely amazing so um let's see here um this is a from from Daniel's weather space station nine months of membership thank you so much um how am I doing ever since Starship test flight I've been doing amazing to be honest I've had an awesome summer it's been fantastic I've got to ride a lot of like bike ride a ton um be able to be outside a lot and uh you know get a lot of work done that's things that aren't around live streams which feels really good you know we're working on another video we're doing about one a month that's the that's the goals about one video a month and we're on track and these are some pretty in-depth and highly animated and um really I'm really proud of these videos and the next one's gonna be great the one after that's going to be I can't wait for the next one um and then the one after that is going to be a really cool tour of a place that you'll learn more about in a little bit um yeah I I'm uh really excited everything's been awesome I'm so happy to be home everything is going well they just announced on the legend by the way everything is still nominal uh but the last question the uh on Daniel's and I'm just gonna put it back up on screen So Daniel did ask um when do I think oft2 the second uh orbital flight test of Starship will be how far do I think it will get so in my opinion I'm still going to be quite surprised if it happens in 2023 um it looks like they're making great progress but you just never know there's just I I mean I'm like I'm either between September and March you know like I'm that's my approximate six month window I I have no reason to think that they aren't making good progress okay by the way we're about to see the first payload deployed um and I'll get confirmation for you guys once they do deploy that um one second yeah okay anyway um so yeah in my opinion like I'll be kind of surprised if it happens this year still pleasantly surprised um there we go wait for confirmation here hold on listening and we have separation of Henry Hertz satellite our first satellite has starting its new life in space it needs to climb to 36 000 kilometers and obviously a whole load of things have to happen in the meantime but we still have our second passenger inside the cylinder can't see it right now can we yeah very good news of course but the mission is definitely not over so the teams are extremely focused because we have another passengers to deliver okay we'll keep answering questions we got a good three or four minutes before they do the second deployment here so um I yeah I want to go back to still answering you know uh Ryan in our in our Discord says uh Ryan thinks they're on their way for an October launch as of right now I mean I yeah part of me thinks sure if everything goes well at the construction site it does feel like honestly September up to October might be a possible ability um but you know there's going to be a lot of new things going the water delude system you know the shower head plate steel plate thing um you know I wouldn't be surprised if though if they get it done enough and say let's try it again and hope that it goes better than last time um but it seems like the Rockets making pretty darn good progress but even you know once I could see October by the end of October maybe seeing a booster out there doing some test firing but you know you just never know with that stuff will it go well they're going to be installing new methane tanks and a lot of new infrastructure as well is that all going to run smoothly um this is new stuff again you know we're back in that territory of like well they're changing everything and before the next launch so that's why I'm kind of like you know um we'll just have to see we will have to see you uh let's see here this is okay yeah this is from Marius talking about when we're talking about the um Astro Awards live will there be representatives for the missions that win Awards to receive them oh they can't they just confirmed that the the little payload adapter cylinder thing just popped off which is great so they can deploy that next satellite But to answer this question yes that's one of the whole big entire points of this is we are going to fly out representatives for from all of the different uh people that get nominations um out to to you know gather their Astro Awards live and actually be part of something that's big and a big celebration so that you know these people working day and night on these incredible missions and programs and um you know science missions get a chance to have public recognition for their hard work and that's what the whole point has always been of the Astro Awards um yeah that's kind of what I'm most excited for um so there we go um oh and this is from uh Morton saying they're installing a big steel plate under the the orbital launch Mount right now yes they are one of the first ones the first it is the first steel plate now they poured all the the um the concrete out there so by the way here we go we're getting ready for the second satellite on all these operations and sending back the data here to the CVI teams who then uh you can provide that to the range operations manager Raymond Boyce to announce this is the scheduled time for separation and we have separation of Syracuse 4B that's great news Ariane 5 has delivered her second passenger bang on target over the Indian Ocean congratulations to all the Syracuse 4B teams and to the H2 sat teams best wishes to all the teams now on the ground in the two control rooms taking over your new satellites and going through the early phases of the operations happy faces all around here congratulations to all the teams of course we'll see a funny passenger here in the control room with the requisite sunglasses what emotions it's a very emotional time because rn5 has of course performed flawlessly and beautifully and the teams now very very happy of course the work is done for some but for others it's just beginning yes because well my friends you can see it on their faces that uh they're all relieved and happy that the last Ariane 5 launch uh went down in history uh successfully as a as a mission success looks fantastic um what a beautiful send-off to such a historic and iconic rocket as the Aryan fire so everyone in in chat just say your final well wishes and thanks to all those that made this possible I'm going to work on heading out here though uh Lewis Rogers uh we are working on trying to lower the cost though of all of our rockets in the future so um hopefully someday hopefully it can get to a more affordable price that you feel comfortable with but that's gonna do it for me guys um I'm gonna work on heading out here final uh you know final little words here if you guys want to help support what I do head on over to patreon.com everydayastronaut or hit the member button here or you can subscribe on Twitter as well they all have the same you know basic perks like I said we're going to be sending out a thing tonight um a little poll about the Astro Awards if you want to get your opinion heard we're going to wait our supporters as like you know more uh you know those are obviously people that are financially invested and just really serious about uh about this the most likely people to try to come and attend um so we're going to be taking and doing that poll and then do a separate Poll for the general public because it still is extremely important that the general public feels welcome and capable of coming to this and we're going to do everything in our past you know everything we can to uh to make it so that you people can afford to comment and that it's convenient and an awesome event all around I'm really really really excited it's excited for it so all right that's gonna do it for me though guys if you uh stick around there's gonna be a new video hopefully maybe by the end of next week if not the week after that I gotta do it before Ragbrai though that's for darn sure um hopefully we you guys tune in for that video and maybe I'll do another another uh live stream here and or there will be a supporter live stream again in a couple weeks as well so thank you all so much for tuning in uh it was a huge success and congratulations to Ariane space and the Ariane 5. great work out there to all the teams um what a beautiful beautiful send-off that's gonna do it for me I'm Tim Dodd the everyday astronaut bringing space down to earth for everyday people goodbye everybody thank you for tuning in [Music] [Music] foreign [Music] foreign [Music] [Applause] [Music] thank you [Music] foreign [Music] [Music] [Applause] [Music] [Applause] [Music]
