SpaceX Falcon 9 Launches HTS-113BT (Merah Putih 2)

and here we [Music] go we have LIF off propulsion continues to be nor R 68 chamber pressure looks good probably enough water tow [Music] fly go down to [Music] nominal it's orang my [Music] God 343 unfolds to go inde we rise together back to the moon and and Beyond M me to be exiting in the flare [Music] correct you we don't need any more of [Music] these good afternoon from Florida Space Coast you are taking a live look at space launch complex 40 at the cape canaval space force station in Florida where in about about an hour from now we will hopefully see the launch of the mirati 2 mission I will be your host Sawyer Rosenstein and I see all the 5x fives in chat which I appreciate meaning that you can hear me but it won't just me that you'll be hearing of course joining me with the uh co-hosting duties here is Alex how's it going Alex I'm doing fantastic we have another launch from the cape and of course it's another Falcon 9 so I had to be here got to show that Falcon 9 love and also here with us with more Falcon 9 coverage out in the field is Max how's it going Max hey good afternoon everybody and welcome to a very Blustery Day on Cape Canal space force station for rejoice a daytime Falcon 9 launch yes it's been nice seeing more of those lately what isn't so nice is seeing that camera Shake because the winds are indeed quite Gusty so will'll have to see if they stay within limits for liftoff but before we talk about that let's talk a little bit about the mission itself so we've seen it as uh Telcom HTS d113 BT is the official name but we've also referring to it as meuti 2 so what exactly is this yeah this is a communication satellite uh that is is essentially uh owned by the by by the state-owned company Telcom set they're basically the ones that tend to provide the the communication services for Indonesia so this one has been built by T selenia you can see sort of the the um the logo on the side there of that company and and and then so this is sort of a fourton communication satellite it'll it's supposed to go to the 113 um degree East location out in geost stationary orbit falcon9 will not drop it off directly into geost stationary orbit though it'll be on a geostationary transfer orbit that it'll be dropping it off and then the satellite will do its own thing and it'll go into its final position and and all those things with its own propulsion and and so that's why the name of the satellite has that 113 BT thing I don't know what BT means or stands force to be fair uh might have some uh significance or or something uh but the 113 it stands for that orbital position at 113° East over Indonesia basically and so yeah this is supposed to to be able to provide about 32 gabyt per second of connectivity uh to all all of the uh you know customers uh over o over Indonesia and and that's sort of the the the main goal of this is just basically a communication satellite now you may remember for those that have been following Falcon 9 for a long long time that maruti is like a familiar name uh and that is because SpaceX already launched another satellite which was uh it was the Telcom for uh or Telcom set for uh satellite which was also nicknamed maruti but that was merti one and this is the two so this is the second one that is called like that I really don't remember I'm I'm trying to to to look through here what is the the meaning cuz it's like some kind of meaning in in uh Indonesian so I'm I'm fast uh fastly going here quickly going through uh the the significance uh of the satellite name but I cannot find it I had it I had it somewhere okay well uh I'll look it up and then uh I'll try to to to talk about it later but yeah it's one of these other satellites that they have built uh and and that you know they they are developing uh for for Telcom set and so in that case that one was with Space Systems Laural it was a different company um for for mer1 it was also the first reuse of a falcon 9 block 5 booster but I'm sure you all know by now this is certainly not the first time they are using any Falcon 9 block 5 booster um in this case this is the B10 67 it is flying for the 17th time there's a lot of launches so yeah just to speed through to speed run through all of the launches it was ser22 crew 3 tur up 5B crew 4 CRS 25 stuning 434 hotbird uh 13g 03 BM power one starlink 52 Starling 55 staring 59 Satria Starling 610 Starling 6 22 starlink 629 and starlink 635 and as always it'll be landing back on on on Earth but instead of you know uh on land like we've had in the in the last few weeks it'll be on a drum ship just with the instructions which is about 650 km down range in the uh Atlantic Ocean and the fings are being recovered by Bob so there you go hi Bob hi Bob oh boy so meanwhile I'm going to be looking through here well you're looking through that uh we've been looking at the camera kind of shaking a little bit Max how are the winds out there um you know it is uh pretty blustery out right now um I don't have the exact wind measurements on me right now but I last I heard we were around the limit of what Falcon 9 can handle in this configuration um it's currently blowing not quite directly south but more so Southeast and upwards of around 20 or so miles an hour so it's it's it's it's blown pretty good some of the white water or excuse me some of the water over here in the river uh here in the space Forest station is white and so but other than that it is a remarkably clear day there is not a single cloud in the sky and there's next to no Haze in the atmosphere at all which is wonderful to see and a great change of pace compared to what the weather has been recently as well um but hopefully these winds stay within limits and we can get falcon9 off at the opening of the window that's what we're hoping for here they do have a 2hour launch window uh that they can go within but we are as mentioned currently hoping and targeting for the opening of the window which is scheduled for just about 53 minutes from now and uh I know there's people asking about the wind conditions and the constraints and things like that um at according to NASA for crew d Dragon flights keeping in mind that's crew Dragon not necessarily the same for a mission with a fairing or from slick 40 uh but those wind constraints are within 30 knots of sustained wind at the 162t level of the launch pad uh is it a little bit higher do we know Alex for UNCW how strong again uh 30 knots at the 162t level of the launch pad boy 30 knots yeah that that does sound a little bit high for liftoff winds well those are the yeah yeah that's NASA when they launch uh crew Dragon that's their constraints oh the constraints yes I thought you meant like the what what is the wind right now no uh I meant in terms of what the constraints are of what falcon can and can't launch in yeah 30 knots that kind of sounds about right all right uh let's see here uh we have a question from raw saying is the abort wind speed higher for drone ship recoveries compared to our TLS recoveries Alex is there a difference well for left off wins uh or or or upper level wins I guess it kind of uh just is all about the asent portion of the of the flight rather than the than the uh lending it is also true that you kind of have to account for the for the winds at the Drone ship side and and those can differ from the launch side when you have an rtls normally the win conditions are pretty much the same as the launch launch wind conditions uh so it it kind of differs in terms of the of the uh conditions obviously because they are different locations but the the uh criteria I don't really know if it's that much different because when you calm down actually a faster win I guess could be a bit uh uh the stabilizing for for the booster when it comes down under a single engine and just the Griffin and things like that rather than when it's going up and trying to go like away from that wind I don't know like I'm I'm I'm not really that that bright right now trying to explain this but I will think that perhaps during a during lending the TRS a little bit higher because you're trying to to Target the Ling location and the wind moving it out uh with a mostly empty booster that will probably be uh easier to move right with with high winds and things like that so I'm guessing there's probably some some differences on the way up and the way down but in in general the conditions are obviously different when you are on on a drone ship because it's way out in the ocean so yeah right and uh with just read the instructions down range for this one uh I think this is the perfect time to bring up the uh announcement that was kind of made about the Bahamas saying hey come here and uh watch The Landings what are your thoughts on that Alex yeah so that that is an interesting one because apparently what they're trying to do is be east of a certain Island which I think it's called Exuma uh within the the bamas archipelago or like the the group of islands of the bahas and and so it looks like given the location that what they're trying to do is sort of try to land the the booster right in the middle of the archipelago or of you know this group of islands and if you look at a map what is that that location compared to the current one that they use it looks like it is a a little bit of a higher inclination orbit that they're trying to Target and I'm thinking this might be so that a SpaceX doesn't have to go around the Bahamas for a launch to a 53 degree inclination orbit cuz the ones that we're seeing Lately from well lately for like the the past 40 staring launches from the cape right uh the the past 40 launches from the Cape of starlink have been to a 43 degree inclination which is not really that high inclination it's sort of like Midway through between Z and 40 uh and excuse me in 90 so it's it's almost at 45 so yeah 43 is almost there to uh halfway through that that Midway point and so that uh inclination allows them to just do like a slight small dog leg around the balas to be able to go into 43 degrees but if you want to go to 53 degrees which is where they're going to be launching their direct to cell uh satellites for example then you want to you want to have to go a little bit more south and you can't because the the Bahamas is just right there but if you can actually overfly and land in the Bahamas then that's easier right uh you don't need to do a dog leg or anything like it and lost and lose performance and so that is precisely what I think they're going to be doing uh in the near term where they're going to have the Drone ship right there in the middle of those islands and then be able to go into 53° inclination I know there's a fight in the back channels of who's going to get to go down to the Bahamas to go watch The Landing uh I volunteer his tribute as well uh let's see here uh let's talk a little bit about the uh Landing itself you said it's going uh down range for something like a starlink but for a mission like this uh it's a little bit more simple than that so Max uh what is the trajectory for today's launch so Falcon 9 today is heading straight on into a geostationary transfer orbit so essentially if you locate or if you put yourself on the Space Coast of Florida it is essentially launching straight East um as opposed to a starlink as we just talked about launching Southeast or an ISS trajectory launching Northeast at about 51.6 de geostationary transfer orbits or or just geostationary orbits in general tend to launch directly straight East so it'll be a lot easier to see if it was at night because of course it would be a nice wide Arch whe whether you were North or South the pad regardless uh but for orbits uh heading heading out to GTO they are always heading straight East awesome do kind looks yeah and and in that map kind of looks like it's curving a little bit that's because that's sort of like the trict Tre that you do when you go into orbit that kind of Curves a little bit South it is not that it's sort of doing a dog leg there or anything like it's just that that's sort of the the overal mechanics of of things it's uh what is it the coris effect or something like that but anyways yeah when you go into orbit since it's like a circle right so uh when you project that onto a map it kind of looks like it's curving South but that's pretty much what an orbit looks like when you try to project that but yeah looking up from the cape it should be straight away to the east there we go uh here's a question from Jeff and this is probably a perfect technical type question for you Alex uh at T minus one minute we always mention that the tanks are pressed to flight pressure uh Jeff's wondering what are the tanks flight pressures oh uh I don't think they have talked about this uh like what is the actual number of bars and and things like that I know for example for Starship Elon has talked about the pressures cuz there was a point where that was an issue and and he was concerned about the quality of the tanks and things like that that that was four years ago by the way just to make us everyone here old yeah that was four years ago when they were having troubles with that uh how things have changed right um but yeah it on on Starship is about six bar I don't think it really needs to be that high for for for Falcon though cuz I believe it's it the the tank pressure kind of relates with how the engines work and also what else is going on inside of the tank and so if you have like a engine like like Raptor where you have like full flow stage combustion things like that you probably need a bit of a higher tank pressure but in order and also for the structural concerns as well cuz it's like thinner stainless steel alloy if you have a even an even thinner body then you probably need a much higher pressure like Centaur for example uh but we really don't know for Falcon 9 though uh that's that's sort of like the the issue here that um yeah we don't we don't get to know those those numbers that's all right no pressure oh wait I knew you here we go I'm sorry I had to someone take the bingo carard already Sawyer makes a pun that should be the free space uh uh but in terms of actually pressurizing it why do they pressurize the flight tanks for those who don't know yeah so that is that is a great question because you could think of of it well if it it's it's on the ground right why do you even need to to bring it to flight pressure like why does it have a flight pressure all right and the thing is when you pressurize the tanks it kind of gives it a more structural uh stability it is not that they cannot stand by themselves without the the pressure right um but what it does is that when it's flying it kind of gives it gives it more uh more rigidity and more uh strength so to speak right and so the difference between on theground and onlight is because during flight is experiencing tons and tons of force from every from everywhere else right like as it goes up it's getting uh hamic pressure on the top that sort of tries to compress the rocket it is also getting bending loads from side to side from different winds uh being you know uh hitting on the rocket differently on one side of the other the the the torque of the engin like there's so many forces acting on the on the rocket compared to when it's on the ground where it's just gravity right and so you kind of need it to bring up to to a flight pressure because it kind of gives it a more structural strength to be able to support that a similar thing we see for example when they move uh things at Starbase and just to connect a little bit with a recent move that we have had at Starbase uh right now uh where they pressurize the the tanks on the booster or the ship to be able to basically the the transport uh of going from the launch site to the production site or the production site to the launch site it is not a flight environment right but you kind of want to have it pressurized so that it can support the the different loads that you see during a a transport o of of that nature uh and it is definitely not flight pressures but it's higher pressure than you can see probably when it is sitting just on its own there you go so now we know why they are pressurized for flight thank you Alex uh here's a question for Max and I'm going to regret asking this but Mark wants to know stby today you know I love how this has become a fairly regular question so thank you very much Chad that means that means that means a bunch to me against all the stubby nozzle haters um I I think given the performance needed between the upper stage and the booster today I think this calls for the full-size nozzle unfortun um not much more to say than that I'm heartbroken oh no heartbroken uh I do want to thank some support here just a fair warning we're working on getting it so we can actually see your name on screen but I still want to shout everybody out uh we've got Josh zero thank you for the support saying Falcon 9 strap with two Starship boosters that that sounds like the most cursed Falcon heavy in existence Blas yeah yeah that just no and then uh we've got musical wol saying what's the highest win during a falcon9 liftoff I know we were talking before I believe it's about the max suain it can take is 30 knots which is I believe 35 M an hour 50ish kilom an hour if memory serves me right and that's a lift off cuz then altitude it will take more uh I remember I don't know max if if you even remember some of these launches but I do remember a while ago we had like a few launches where it was like 120 knots at like 40,000 ft or something like that it was very high up it's like upper level winds but they can be stronger cuz the air is thinner um so it was like 120 knots or something and and again 40,000 or 50,000 ft up in in the air that was that's bunkers yeah it's also worth noting that Falcon 9 is actually one of the more vulnerable Rockets uh for compared to wind because not only do you have to deal with launch wins you also have to deal with Landing wins which unfortunately uh for one of the most I can't remember which Mission it was exactly I think it was either USS ussf 124 or Pace I think Pace yeah I think the the actual launch attempt was scrubbed because of Landing winds because because of course the the first stage coming back back it's missing a a vast amount of of of propellent and thus and thus Mass compared to compared to how it was for liftoff which means it's much more vulnerable to a crosswind and being blown left or right which means it's that's a lot more work for the for the uh grid fence to to put in to keep it aligned uh because the last thing you want is for falcon9 to hit a gust of win on the way down it be blown sideways or blown to a point where the the grid fins cannot um compensate and correct for before you the you can initiate the landing burn so launch and Landing winds are a high priority for Falcon 9 yeah and even during asent because it's like super long and super thin like the the finest ratio I think it's called right it's somewhere around 20 or something like that like the the ratio of how tall it is compared to what is the diameter of the of of of the rocket is like a lot compared to other Rockets like at or or even the most recent Vulcan and things like that like it's just super long and so with with that when you go up and you have like WIS it in that case it's not like the intensity but more like the share you have the the wind hitting on one side the wind hitting on the other side you have a lot of um bending forces that are trying to to bend the rocket uh at the at the inner I I think actually for the inflat abort test one of the reasons why it broke up I I I think I saw like the second stage broke off from the inter stage and the booster broke off but the second stage came intact to the to the ocean like I remember one photo I think it was from Jon Krauss that he captured the impact of the second stage and the second stage as it came back down so that was sort of a a view of what it would look like if you were to to bend a falcon 9 so that is that is sort of the the kind of bending uh forces that it has to fight against during asent so yeah hi wind saying hi Shar of of when that that is not good for the rocket yes and it's also worth noting that Falcon 9 as it currently stands in the block five configuration the tank structures are as tall as it can be for how wide for how wide Falcon 9 is is exactly so Falcon is pretty much is as big as as as it's going to get at least when it comes to the tank structures we are now about oh sorry I just want to mention that we are about 36 minutes away from launch now at this point so we should be getting hopefully the verification from the launch director that we are go for propellant load and if that's the case they will start loading in about 30 seconds beginning with the stage one rp1 load rp1 being rocket propellant one a refined form of kerosene and the stage one locks load also Begins the liquid oxygen or Loxy as we like to call it here the same time on the second stage the rp1 loading will begin there so notice that the uh rp1 and locks are simultaneously loaded into the first stage but loaded separately during the second stage which will lead us to our favorite uh T-minus 20 minute 20 second vent a little bit later in the count that's something that I was actually going to ask Max cuz usually about 2 minutes before they start Propel load but usually they vent the Falcon n tanks ahead of that but I don't know if the win might have been conducive to Max hearing that I don't I don't really know because I know most of the time he's like oh I hear Falcon 9 venting and it's like tus 38 minutes and I'm like oh yeah that's that's the Falcon n tanks are venting for propell Lo that's actually the call out yeah one one of the cooler parts about watching on the cave side for like 40 is if if the winds are right especially with our two primary reviewing locations you often times can hear Falcon 9 venting before they begin prop load unfortunately with the winds peing like they are today it might be difficult to hear over but I am looking feverishly through uh my other camera here at the te to see if you can see any uh signs of prop load yeah normally we start seeing that Frost appear on the booster around tus 32 tus 31 30 seconds more or less so that's so basically in about 2 minutes we should probably start seeing something if they have begun propad or maybe SPX uh tweets about it so yeah for reference the last tweet from SpaceX was that they rocket was vertical at the pad and that they the 2hour window open 3:11 p.m. Eastern with 95% favorable weather and as of now they are still targeting uh 311 p.m. Eastern for liftoff so about 33 minutes from now here's a question from Soul 24 and uh this is always a fun one asking uh why are there four lightning towers that slick 40 which we can actually see all four of them today uh whereas there's only one at 39a and star base Alex what at Star base is is there a Lightning Tower at Star cuz I haven't seen any I think that's just called the launch Tower itself at this point yeah or Star itself yeah uh at 39a I believe it is because so the reason why you see those Towers it's not that the lightning hits those Towers is that they are there to sort of be able to connect the cables that are actually acting like um like basically the the points where the lightning will try to hit instead of hitting the rocket right you're trying to sort of cover the rocket in those cables or try to have like a like a electronically uh insulated uh cover around it right and so at 39a what you have is like just a single one because from there you you can extend all of the cables around the the launch complex and protect the rocket so you don't really need a like a set of four Towers but for example at 39b which is where SLS launches from um most of the time there's no there's no launch Tower there cuz it's a mobile launcher right so what they do is they have uh fixed um lightning Towers right and in that case it's actually three rather than four it's a bit more weirder but it's okay and they actually much larger uh lightning towers that the ones that we see here at 40 and the same thing they are just there to be able to to hang all of those cables that they eventually are used to be able to protect the ruget in case of lightning uh we are getting confirmation that the vehicle is venting visibly at this point which means they are proceeding onto the uh fueling but while we're talking about those Towers uh I think they're listening I'm sure they're telling us that they're talking about us again which is indeed quite shocking I love the pun and I love even more so that the pun is on a shirt that we actually have in the shop at shop. nasaspace blake.com so yes we have The Four Towers merch available so you can get that on a shirt you can get it on a coffee mug it's I love it I I love the pun part of it and just The Four Towers with catary wires so just selfishly any gear that has puns on it is one of my favorites I have to ask though like is it is it too soon for Four Towers because technically over at 40 now there's five technically speaking we're just talking lightning Towers though I don't think the creu access Tower counts as a lightning Tower but it's still a tower oh my gosh but but then the joke doesn't work the whole point is that it's uh shocking because of the lightning it's almost a joke it's it's almost within it's almost a joke within a joke because there's four lightning Towers but technically there's five Towers but the four Tower joke you get it now that my head hurts let's continue on with some questions here but first I do want to thank uh Nigel for gifting one membership as well as RC Horseman gifting five memberships thank you very much for that and uh Max this one is for you from i' rather be flying an X-Wing saying the best thing about today is it's a real nozzle the best thing about a stubby launch is that there's one less stubby nozzle in existence I mean they make new ones it's the same with it's the same with with the fullsize uh Merin vacuum nozzle I reject your reality and I substitute my own thanks Adam Savage appreciate it I'm glad you got that reference soyer I'm really glad you got that reference oh no I I appreciate a good MythBusters reference uh let's see here some other questions we can tackle uh CG was asking any word on what the first crew mission from slick 40 will be perhaps Polaris Dawn uh Max have we heard anything about that well if you rewind a few months we were under the impression that maybe it would be axium 3 and then after axum 3 was slotted for LC 39a then we were we were wondering oh maybe it'll be Polaris Dawn but but from pois Dawn's website or Polaris website uh they have historic LC 39a selected or typed out on their site maybe they could swap it over um or it could be a n crew launch honestly at this point it's it's all up in the air well no it's still on the ground that's the problem oh jeez but uh yeah so that will be interesting the next crew launch crew 8 is also scheduled out of LC 39a and that by the way is coming up in about 9ish days you know if if we could I'll take bets you for a second which one of you thinks um or which crew or what mission do you think will be the first CRI Mission out of 40 um that's interesting I'll put my bet in I I'm going to go with crew 10 I know that's way down the line that's like a year down the line so maybe crew nine um but if I had to guess that before that they might do a CRS Mission from there use the crew access arm as a loading mechanism into cargo Dragon like they do with 39a but in terms of actual people launching from it I I think crew 9 would be the earliest any Alex any thoughts yeah I have thoughts I'm I'm kind of waiting for for a thing but uh yeah it it kind of looks like they're going to try first with a crew uh especially if it uh uh not a crew a cargo Mission excuse me um if the crew mission is going to be like the first crew mission is going to be a NASA Mission I believe NASA wants them to try first with a cargo mission that or maybe they they try with a with a private uh crew mission which in that case will either be polar stone or axium 4 but polar Stone right now is earlier than the summer uh we'll see when it actually launches because it's a very complicated Mission let's be fair uh so there's a lot of development going on there but also the the axium for mission is like October of this year right now so it's going to be a little of time if they wait for a private Mission I'm thinking that we may see first a NASA Mission going from there uh perhaps maybe crew nine which is the next one after crew eight obviously wait that's how numbers work yes numbers right it it's definitely going to be interesting to see I think right now one of the big holdups that we've noticed at least is they have not done a full test of a launch Escape system from the tower so at LC 39a you've got the uh slide wire baskets similar to what they're all also doing a 39b unfortunately no roller coaster but we haven't fully seen the system yet we haven't seen the system in use or being tested and that is obviously critical before actually launching people from there so that's something that we're going to have to keep an eye on too yeah and that's exactly what I'm what I was waiting for here CU I we actually have pictures of the system from Max uh he was out there uh sing remotes and while taking pictures of the FAL 9 you know in the way that kind of tower kind of gets in the way uh right so you can see some of these systems in there as well but yeah yeah at last check from what we saw from Max it kind of looks like a box like uh you hop inside a little box on the slide wire but that is something that we will absolutely keep an eye on and holy cow this is unbelievable support coming in even so much that Jake jumped up to say wow here uh we have we have wilbo tiberious with the 500b Super Chat holy smokes wow oh my goodness saying so nsf's Cornwall to Yorkshire just down the road past the chemist wow um I mean that is unbelievably kind to support we'll have to get uh Chris B on that to get that corn waly Yorkshire there I know Chris would prefer it Point too with Starship but that that the kindness and wow words it's it's rather difficult to find words after um after receiving a support like that because it is the ultimately the the generosity of those who keep coming back and keep supporting us they are the reason why we we we are able to keep going um and for support like that it just it means more than than any words can say so thank you very much Absolut yeah a massive thank you that it's because of your support that we can do what we do and have all these cameras out there both at the Launchpad and on the rocket here and having all the stuff following the uh booster 10 roll at Star base all at the same time while they're doing Raptor testing and McGregor if we could do this without support from Members like you so a major major thank you for that and it's not just the big support which is obviously greatly greatly appreciated it's you know just the support that we get from you guys watching sharing liking that really means a lot as well so thank you we also have Brian Green saying hit that like button for NSF they're awesome which thank you and appreciate I always appreciate when people say that in the messages so I can read it and it's not like me begging people to like but it again it's all appreciated and uh J Keegan a name we know here as well with a punk token for me so thank you I appreciate that that's because he's not uh operating so he cannot put it on the [Laughter] side yeah exactly we get not putting it on screen for that and I don't blame Patrick for it cuz uh I don't necessarily deserve all the punt tokens here hey oh wow thank you Patrick I I will take that punt token happily oh boy we are coming up on the best vent just about a minute from now so we're getting close uh so what exactly is the 20-minute vent I guess we can kind of hit that here while we wait for it to begin Alex yeah so um as we usually know already by now what they what they do right now at this point in the count they finished that rp1 load on the second stage and now they transitioned into the LIC auction load part of the countdown for the second stage and so in order to to get into that dep in the countdown to load that liquid auction liquid auction is a very cold liquid and the lines right now are basically at ambient temperature more or less and so you need to FL a little bit of liquid oin through it so that uh first of all you don't get a flash boil off of that uh liquid auction when you're trying to to flow it through at full uh flows and things like that and most importantly as well the materials just deteriorate if you actually go through with a full cold fluid like this one in when that happens you can see that venting coming off from the te they have that sort of relief file on the side that allows them to be able to um vend that gas is suction overboard um as they chill down those lines to the second stage on the Falcon 9 so that is what it what the T-minus 20 minute vent is all about just chilling down those lines that go up to the second stage uh in order to prepare for the start of liquid auction load in about four minutes from now and Max we always see the T-minus 20 minute event as a great way not only to clear the lines but also to get an idea of the weather this is quite a unique look at the uh at the venting here what are you making of that weatherwise yeah sure is I mean we it's rare that that that we ever get this perspective for launch anymore uh at least on the cape side um but with the vent doing what what it's doing now at least from our perspective is just showing that the winds are essentially blowing right back toward us if we were looking at like 40 from the price site or maybe even our other spot here at the Cape Canal space force station it might be a longer I guess you could say I promise it's not a pun but a cape that that Falcon might be wearing but from this perspective but from from this perspective it looks like it's blowing right back toward us and that's appropriate because the wind is still howling over here but uh spaceex still shows to be having some confidence in the wi either uh calming down below the limits or they they are already below the limits and they and they are obviously feeling confident enough to proceed with prob with for hopefully a launch in just under 20 minutes minutes so keep your keep everyone keep your fingers crossed oh they are indeed crossed and I'll keep my Towers crossed too although actually that would be a bad thing um so at this point cross crossing your Towers that's a new one I I mean yeah I'm trying to come up with something unique cuz yeah you can cross your fingers uh I don't really cross my toes so maybe cross the towers just don't cross the streams anyway um back to the actual Mission itself here um so this is a pretty big satellite is it one of the heavier satellites that they've uh carried up here Alex I believe it's what 5,000 kog uh I thought it was more closer to 4,000 um the mer putu one was 5,800 kilograms that that is true cuz that was that was a little bit larger in that sense or at least a little bit heavier um but yeah it is definitely not the the one with a with a sort of largest size or largest mass uh the heaviest that they have launched on Falcon 9 is about 7,200 kg and on Falcon heavy which is the big one uh that was about 9 tons with the with the echostar 24 satellite back in July I believe of last year so yeah it is definitely not uh the the largest it's somewhere in the middle for a G stationary satellite normally the lower end tends to be about 3 tons middle end it's like the middle of the range is four five tons and then there's a few that are like six or seven tons and the outlier is like echostar 24 at 9 tons but yeah yeah just just a little out outlier there uh okay I love this username if that was methane five memberships we now know Jack's alt account it might be for all we know honestly oh gosh thanks MX Max E I'm honestly I'm I'm still I'm still I still laugh at how long it took you guys to pick up on that it didn't take me too long I I think it's more like Jaz when when he reads your super chats he's like oh we have Max E and I'm like don't you realize that's our Max E yeah that's right yeah that's right it was I think it was one of the Raptor sides but regardless it was still funny oh boy yeah we should you should come up with something like uh passing Max E instead of passing Max Q something like that to yeah really throw him off that could be the moment that could be the moment in in our live stream where we throw it throw it to him so he so that he can prepare with a with a launch that'll be in about 10 minutes right so we we'll get to Max E [Laughter] later oh boy and uh you could see now that the uh T-minus 20 minute event has basically come to a stop which is what we are hoping for at this point everything so far continuing right on time that means that they are now into second stage locks loading that is liquid oxygen going into that second stage it is fully fueled on the second stage with rp1 at this point and the rp1 which is the rocket propellant one refined form of kerosene Rocket Fuel is also still continuing to be loaded along with the oxygen into that first stage as well which for those who missed it Max uh which first stage is this uh the first stage on the docket today over at SL 40 is B1 67 and this would be its 16th flight uh during camera set up this morning actually it didn't look all that soy but maybe we're just jaded uh from from from higher fown boosters but um it's it's honestly wonderful to see that uh many uh commercial entities are are trusting higher higher flown boosters um to to fly their their their their payloads on so um yeah this will be it hopefully it's 16th and uh next flight oh yeah no it hasn't flown that many times only 15 actually I believe it is the 17th and it has flown 16 times either way at least that's that's what I have on my spreadsheet still oh it hasn't flown that much just 15 three flights it's yeah after after 15 or even after 10 it it all Blends together it's amazing just how how how how blah or or how quickly that's become just so blah oh yeah Falcon falcon9 first a has fall over 10 times yeah you know it's fine it'll work it's amazing I think at this point we're more shocked when it's like only flowing flying for it second or third time as opposed to its 15th or 16th yeah yeah that's rare that's very rare and you know uh even if what happened to 1058 didn't happen uh I think we were told I think Elon said one of the present that they were pushing for what 40 flights or so 60 flights on on a falcon 9 first stage beon 20 H yeah yeah they're going to go and push those boosters to the max oh jeez it's it's rubbing off I'm telling you everyone at NSF starting to make more puns even uh even NASA space flight official with some puns in chat the other day so it's a high stakes that's a good one yes I I do appreciate that one now uh as we're getting closer as mentioned for those who may just be joining can you kind of give a quick recap well quick Alex recap of uh the satellite that actually is launching and what its purpose is yeah the the satellite for this mission is the meuti uh 2 satellite that is also known as the hts3 BT HTS stands for high satellite uh the BT I don't know what it means and the 113 it's it it's basically because that's where it's going to be located uh it's going to be going to the 113 degree East location over Indonesia this is uh a satellite built by a tail Salen space or space I don't really know how they pronounce because it's it's an Italian company with a with an English name it's a bit complicated but um yeah and so this is going to be uh Falcon 9 will be dropping it off on G transfer orbit then the satellite will use its own propulsion to reach its uh orbital destination out at 113° East inj stationary orbit and so uh we're looking at a fairly normal GTO uh trajectory here where the Falcon 9 launches to the to the east straight East out of the campe it is about uh 8 and a half minutes into orbit then about 20 minutes later it performs a relide of the second stage to drop the satellite into that g stationary transfer orbit so that's more or less what we're looking here for today booster landing on a drone ship just read the instructions and the fairies will be recovered by Bob that is s of the what I did before but um yeah a bit a bit shorter there you go also I was able to find in my notes what me Puti means because I actually wrote it down but I couldn't find it and it turns out you have to scroll down to find more things on your documents and it stands for red and white and it's basically uh about the red uh the red and white white on the flag of Indonesia so that is the the reason why it is called marutti 2 and there we go I saw a question earlier and I think it's kind of fun to bring this up since this is a drone ship Landing uh just read the instructions is Down Range ready to have the booster land on top of it but someone was asking you know if something happens with the booster mid-flight uh and they can't really go for the Drone ship would they go for an rtls which I know for that part the answer would be no because there are special airspace clearances needed for an rtls and Sonic Boom warnings and things like that but I think it's interesting that people don't necessarily realize that for the landing itself the rocket the first stage booster actually doesn't Target the center of the Drone ship until about a or so off the deck right Alex yeah it it even even during the re-entry burn you see that it is actually not going to the Drone ship it just after the the entry burn it steers itself with a like after the the entry burn you see it steering with the Griff Fin and everything it changes the attitude very rapidly to be able to steer into uh you know sort of in the vicinity of the Drone ship cuz even before the reenter bird it is not even targeting near the Drone ship it needs to steer itself to that location and even then as you mentioned when it steers it's not steering actually to the Drone ship just near the Drone ship just closer right and and it sort of targets the the the ocean near the the Drone ship so if it fails it just goes to the drink yeah that's pretty much so it's a way to save the deck if something goes wrong which we've seen before uh thankfully it's been a while but it has happened and even for rtls Missions it's technically the same thing as we saw with crs1 16 where it was going to come in and land on land and then it had a valve problem and so they just splashed it in the water nearby therefore saving your landing pads yeah and also one thing that is interesting it doesn't even Target the Drone ship itself when the Falon n is trying to land on on the Drone ship it just targets a location in the ocean where the Drone should be supposed to be right like there's no um how to say this uh there's there's no like oh I'm sensing the Drone ship or something like that it's just it targets a ling location right and the Drone ship just tries to stay in that Ling location but if it wear off by even two or three meters it will it will then the the Drone ship will not be there and so that will be a very bad day for Falon 9 so also the Drone ship needs to be very stable like I I think there was a a time where they had a drone ship Landing in the Drone ship one of the thrusters wasn't working and with one of the thrusters not working it doesn't mean that it cannot move but it cannot hold uh a precise location on the ocean and so it wouldn't have been a good day for Falcon n to be able to land on that drone ship because then it will not land on the Drone ship right the Drone ship will have drifted or something like that and it is a very important thing to also have the Drone ship in in good condition for a landing yeah that kind of helps uh Max I want to do one final wind check with you before we send you off to go operate all the cameras out there has the wind calmed down gotten any better cuz I know there was concerns that might be on the edge of the go noo limits yeah I don't know if it's the placebo effect or if there has been a a real change of wind wind speed but it seems like it has gotten a little calmer I'm seeing a actually quite a bit less White Caps here on the water in front of us um but I think so far things things are looking good obviously uh we are well almost finished with prop loading now uh but unfortunately it is time to bid both of you a you for a little bit so uh good luck and godsby gentlemen and I will see you on the other side sounds like a plan happy tracking all right we are getting that much closer to launch now we are about T-minus 6 and 1/2 minutes at this point the uh engines should be conditioned ahead of launch so uh what happens at tus 7 Minute Mark there Alex yeah so pretty much like they do with the T minus tournament event where they chill down the lines to the second stage they do a similar thing but with the Merling engines where they chill down the lien turbo pumps on on the Merling engines precisely for the same reasons before to not have flash boil off of your oxygen into gases form and and also because that that liquid auction if you try to bring the metal on on the engine from ambient temperature rapidly to cryogenic temperatures that can make the the metal shrink very fast it makes it brittle and things like that that that is a very bad day for for the engine so what they do is these sort of engine chill where they flow just a little amount of that liquid auction through the engine turo pump to be able to to cool it down ahead of flowing it at full pressures and full flows so yeah that is sort of where we are right now we should also have already loaded uh that rp1 on the first stage so rp1 should already be loaded on the first and second stages and soon we'll see the transport director on the on on on the PAAD there retract a little bit out from the rocket and you can see it on screen as well yep you'll notice right underneath the fairing there they're kind of these little clamps it looks like those will open up and then the you will get a retraction of about 1.8 de so we're not talking it moving back super far which you can actually kind of see the clamps opening up from Max's view there uh but it's just a little bit ahead of liftoff and then at the actual launch itself it will do the throwback maneuver uh where it will lean back a lot farther to get out of the way of the vehicle that also as the vehicle launches the lines that have been connected to it the ones that have been fueling it providing it electricity uh even providing uh conditioning for the spacecraft inside of the payload fairing those will all retract away so that they don't get ripped off and that they can also then be protected and used again especially with the current Caden SpaceX has in say 2 3 days from now yeah in fact the next launch after this is on the 24th so four days from now and that will be another starlink mission but for this one now we are under 4 minutes away uh from from the Mira pouti launch here and you can see now that strong back retracting slightly away from the vehicle keep you mind a minute ago those clamps were around the rocket now they're open there yeah just a little uh way there you go you can see it and vehicle looking Frosty which all of that again is completely normal that is because of the super cooled propellants that are inside of the tanks and the warm ambient temperatures of the Florida Air on the outside we are now approaching the T-minus 3 minute Mark so uh at this point fueling is getting close to wrapping up right yeah the first thing will be first stage lox load complete that'll be when the Falcon n booster is going to be fully loaded with propellant and then about 1 minute later it'll be the same but for the Falcon 9 second stage and then the whole rocket will be already fully Rel loaded with propellant by that point so and after that we're going to see a return of that strongback vent right it's not going to be the T Min minute vent right it's going to be T minus one and a half minute vent and that is when they do those gas Closeouts where they vent out the remaining liquid auction on the line so that you know it doesn't do any boomy stuff at liftoff yeah we definitely don't want that and then again A T minus 1 minute is when the big Milestones really begin with the pressurization of Tanks to flight pressure and Falcon KN entering startup meaning the onboard computers then take control of the countdown hopefully leading to an engine ignition at tus 3 seconds and a liftoff at t0 we are now at 2 minutes and Counting uh as you mentioned we should be keeping an eye out for that final vent a couple seconds from now about the Midway point up the transporter erector that metallic gray structure that's partly blocking the view of the rocket currently there it is and stage two look load is complete Falcon N9 is now fully loaded all right it has all the propellants it needs and uh it's going to be conditioning itself now to get ready for liftoff about 90 seconds from now and again this is completely normal as you mention purging the lines of any remnants of the liquid oxygen that was in there and it's super cooled hence all of the vapors that you see we are now continuing here to T-minus one minute so Falcon 9 entering startup and the tanks pressuring two flight levels the next thing we'll keep an ear out for or an eye out for is the launch director verifying that we are go for launch which will happen at the T-minus 45 second mark and there is T minus 45 seconds we'll let you know as soon as we hear the official word you're now coming up with t- minus 30 seconds we have the confirmation that Falcon 9 is in startup as we continue the countdown here about 20 seconds now till liftoff we are go for launch in about 10 seconds from now we will hopefully see liftoff of this Falcon 9 keep an eye at the bottom of the rocket potentially for a green flash followed by the water delue system which there it is ignition and liftoff liftoff of mea py 2 on its way to geostationary transfer orbit and it is is on its [Music] way [Music] I [Music] you can hear a little bit of the wind still there but amazing sound of the launch as you can see there the rocket now passing through the speed of sound and approaching Max Q which is maximum aerodynamic pressure being forced onto the vehicle there so far everything continuing to look great so far for Falcon I's flight fantastic onboard view is always there from SpaceX the next thing that we're going to be keeping an eye out for is three events happening in Rapid succession the first being Mo main engine cut off when the nine Merlin 1D engines which you see there spreading out in the thinner atmosphere will turn off that'll be followed by first and second stage separation and then ignition of the Merlin vacuum engine on the second stage which is SC1 or second engine start one followed about 45 seconds after that by payload deployment or payload fairing deployment excuse me probably too early little too early there yeah you can see the vehicle already about 50 km up and we should be seeing that Mo momentarily the main engine cut off and there it is we have Mo and we should be seeing stage separation there we go the non stubby nozzle on the right is the Merlin vacuum engine on the second stage the good nozzle yes the stiffener ring falling away and we have ignition on that engine we see it's starting to Glow there so for those who don't know what is that ring that falls off there Alex yeah that is a stiffer ring that sort of keeps the structural Integrity of the of the end portion of the mvac uh nuzzle because that is a very thin nuzzle extension that it has and so you don't want to have it during as to vibrate too much and move around and and potentially breaking off and so that is sort of the the the uh protection that it has uh to make it more rigid and we're coming up here on Fair in separation and here's a view inside those fairings and there is the separation revealing the spacecraft now to space and those fairing Hales will be recovered and likely flown again in fact we had confirmation recently that uh fairing one fairing half at least has been flown 15 times with a plan to fly it again for a 16th yep and speaking of the I guess I should say um it does uh have a benefit to have the the stiffener ring on the mvac engine But If You observe our latest uh so this is the current Falcon 9 launch right the previous Falcon 9 launch we covered it it was from Vandenberg and it didn't have a stiffer ring so if you look the footage it didn't have a stiffer ring and uh yeah it seems like maybe SpaceX is doing a best part is no part kind of approach with that uh piece of hardware could be and I love the view on the left again with the uh grid fins extended which don't do much at this point but once we get into the thicker part of the atmosphere you'll start to see them moving and helping to steer the vehicle for now though a lot of those fine movements you could see like from that puff there are using the cold gas jet thrusters to help kind of maneuver it so how exactly do those work Alex yeah so those thrusters are basically uh gas nitrogen that are loaded on on high press copvs on the interest oh actually not in the in the interest stage it's actually on the rp1 tank but um yeah so those uh that that nitrogen and high pressure you release it and you create thrust just like I guess a fire extinguisher kind of thing just with nitrogen rather than CO2 and so you have that that the bottle and you just open up off it's very simple it's not really that uh that complicated to to to use during flight and so that's why they use it on Falcon 9 it's a very simple system there's like I think four thrusters per pod and there's two pods separated 180° on the inter stage of Falcon 9 so that's what they use for for maneuvering as they are out outside of the atmosphere but as you mentioned once they are through the atmosphere they use the the grit fins most of the time the thrusters are still useful but majority of the of the guiding is with those uh gin getting great views of the second stage today there with the Earth behind it now keep an eye on the left we should be starting the entry burn momentarily that will help slow the vehicle down by fighting fire with fire basically using the fire sort of as a heat shield to kind of slow itself down and protect itself as it goes through the atmosphere yeah and there we go we have ignition on that entry bird you see in the bottom left the first stage speed decreasing dramatically the altitude as well continuing to go down this is also how the boosters get syy as you can kind of see the camera getting a little dirty there it is a carbon based fuel so flying through all the carbon based you get soot and that's how the vehicles get syty take a look at the the Griffins now cuz now they're they're trying to steer the thrusters are firing this is what I mentioned before right that after the in burn it tries to guide itself to the vicinity of the Drone ship again it's not fully targeting the Drone ship but it tries to get near it and then during the landing burn it steers all the way to the Drone ship but yeah it's kind of crazy this this part and there's a lot of clouds there so maybe we'll see the the booster flying through the clouds it's going to be awesome right and so we should be seeing the second engine cut off on the right first followed by Landing burn and hopefully touching down on the Drone ship so you can see now 9 km off the deck it is really starting to slow down down to 1300 km an hour and dropping quickly which is what we want to see we should be expecting seo1 second engine cut off one any second on the right side of your screen and you can also start to see on the left side the grid fins are starting to wiggle says the thicker atmosphere they are helping to steer there we go we have SEO one second engine cut off one start there's the Drone ship ah is amazing still sing by for Landing Lake deploy there it is and a little bouncy there but touchdown another successful Falcon 9 booster Landing this time on just read the instructions and the streak continues yep Alex I know you've got all the fun facts about The Landings and things like that how many are we at now since the previous f failure this is the 201st uh since since that uh last failure with b159 and the funny thing is that you probably saw the deck of just through the instruction it was very clean and very well painted that was because for this uh flight this is the first uh flight after it has undergone like a refur a refurbishment process and so it was painted like it's super clean it it doesn't look like all beat up like like before for now I that's going to change I'm sure before the end of the year as it supports a lot more Landings oh boy that beautiful launch there uh I know Max has already had to leave his viewing site but definitely want to thank Max Evans for his camera work and his contributions leading up to this point in the Stream so just want to acknowledge Max and thank him for that even though he likes the stubby nozzle we can forgive him uh we are going to keep an eye out on hopefully the vehicle separating soon uh unlike most missions where we're waiting like 40 45 minutes for separation uh this one is scheduled to separate about 18 minutes or so from now following a short second engine burn of that Merlin vacuum engine it's a roughly four or 5C burn approximately again when we say all these times with approximately uh the issue is that uh no it's a it's a it's an approximate one minute burn oh excuse me one minute thank you yeah uh we say approximate because SpaceX does give us rough numbers but they're actually calculated by the vehicle itself so if for some reason and it's a couple seconds longer or a couple seconds shorter it's totally fine it's just the vehicle is calculated oh was a tiny bit faster a tiny bit slower than I was originally thinking yeah I want I do want to thank some support that we've been getting uh we've got bford gifting five red team memberships thank you very much for that and Coco cats gifting a red team membership as well which really appreciate all of that and a boat kind of blocking the view there but this is where the booster will return hope in just a few days on top of just read the instructions to be taken down and flown again right yep um just read it's it's about to the left of here where it will it will be sort of ducking there and then there's a crane that picks up the booster puts it on a on a stand and then the Drone ship sells off again out to to see I'm guessing that it is going to be like two missions from now so not not the next mission from 40 but maybe the next one after that which maybe I guess a starling 640 cuz the next one might be happening with ASO with a short flow of Gravitas and stalling 639 so yeah yeah it's if you've never seen it from our Fleet cam which is the view you're looking at right now on Space Coast live 24/7 it's kind of crazy how they do it they literally put a cap on top of it not a beanie cap like shuttle but uh lifting cap on it uh raise it up bring it over fold the legs and off it goes to then drive down the roads of the Kennedy Space Center and Cape gaval space force station back to Robert's Road for refurbishment which I I saw a video yesterday of a tour bus that actually happened to be pulled over on the side of the road as one of the Falcon 9s was driving by if you've never seen that it it really gives you a scale of how big this vehicle actually is it is long and rotund and I mean that in the nicest way possible and you can see there that sort of map view um it's about a 20 minute trip from when the second stage shuts down and the moment that the relight the engine to put it into a sort of transfer orbit into G stationary orbit so it that transfer orbits like an x-shaped kind of orbit where the perg is more or less at the same altitudes at Leo sort of around 170 to 200 km up in in above the Earth but then the the APLE the sort of the highest point in that orbit um it could be anywhere from like 20,000 km if it's like a a Subs synchronous that we call it or a super synchronous which is above the the G stationary Bel belt that will be over 36,000 km with this kind of mass though I'm going to go ahead and guess that it's probably going to be super super synchronous it's probably going to be about 40,000 km of Apple for for that one but we will not be able to to see it here on the Telemetry from SpaceX though that's going to be later after um the I think it's the US space forces 18 uh Squadron or something like that they they track things in orbit and they post where what's what's their orbit and things like that that's going to be when we figure out what's the what's the or here is a great question from Papa Hawkeye asking how long does it take for the Octo Grabber to attach we really haven't seen that in action in the sense that it going out it has like a mini Garage on on the I think it's on the back side of the Drone ship and so it goes out and and sort of slides underneath of the of the booster but we don't really know how long it takes cuz we haven't seen it in action so it's a great question but sadly we we we really don't know it will be awesome if SpaceX could put out some video of it in action and and see how it works we see the the the aftermath of it of the Octor Grabber already attached to the to the booster but not the the in between and for those don't know the Octor Grabber as it's known is basically what is used to secure Falcon 9 during its return from out at Sea this case I'll just read the instructions all the way back into the port without the risk of it being knocked over or anything like that although your vehicle unfortunately is weak enough like 1058 it will just snap in half I'm sorry I I I shouldn't have brought that up it brings back bad memories we love b158 yeah I kind of snapped there uh Allan also getting out here from the store saying great stream guys be sure to visit the store for orbital test flight 3 swag getting the of3 patch there designed amazingly by Paul Leen so thank you for getting that and thank you for the Shameless store promotion let's see here Jan is asking have we had a booster been retired after end of life yet I guess you interpret that a couple different ways either I guess ending its flying career as well as sending it off in a place of Glory yeah you're correct cuz you could interpret that as just being retired and put on display or being scrapped at McGregor we've seen some of some of the old uh block to and block three boosters scrap there at sort of what what I call the booster graveyard at McGregor um um but yeah and and and for Block five it's a different philosophy I think where they try to fly them as much as possible and when it is not feasible to to fly them anymore their last flight is s of an Expendable flight right and we have seen that for um so booster 1046 which was actually the one that launched maruti won uh its fourth flight was with the inflatable test and then um B1 51 b14 9 those two were expended on sort of the last mission possible I guess that that is spasic said okay you're not going to fly anymore but instead of you know rotting away in some scrapyard or something you're going to be flying for a last time a a last time uh just of you know achieving something more which is a another excellent launch with another Falcon 9 uh in that case it was two customer missions I think it was udat 10B for 49 and Galaxy 3132 I believe for I'm trying to do that without looking at my spreadsheet by the way uh so yeah th those those two went out on a on a place of Flory right that's that's the expression that that you guys say and yeah um the bking funeral by the way common Alex Flex with the uh without having to look at the spreadsheet well it's it's also because it's like those are the missions where they expended a falcon 9 booster I I guess I should also say b147 was also expended on purpose uh I'm mostly sure that probably someone in the comments was saying 1047 1047 was also and I just remembered it uh but I I I wasn't looking at the chat if if someone was saying that by the way I just remember it when you were saying the spreadshe stuff because it is true that all of the early ones uh Falon 9 block five boosters they were like the early versions of this sort of experience now they have a lot of flights on later boosters right those boosters have been built with the previous experience of these early ones so this early ones probably were not meant to be reuse a lot of times but at least more times than block two and block three cuz those were expended on their second flight so yeah um kind of looks like these early block five boosters they were just not they were just not uh there to be reused a lot of times let's be let's put it that way and there are boosters that you can go see yourself in person there's the Gateway exhibit at the Kennedy Space Center they have one as well at the Johnson Space Center and one in Colorado as well and ironically none of those are block five because of this because where we said that when they try to retire a block five booster they sort of have that biking funeral of just okay okay you're Fly you're flying for the last time and it's going to be Expendable launch you're going to go on a on a bliss of Glory so yeah either that or you are the weakest link goodbye more references uh here's an interesting question from Rory first I do want to say someone in chat named Kevin Michael Reed says Alex doesn't need a spreadsheet Alex is a living spreadsheet nah I do need I I do need this spreadsheet there's so many boy there's so many things I have so many pages in this spreadsheet uh that I I will never be able to remember off the top of my head there are things again things like when certain boosters were expended uh it's easier because it's been like just a handful of of Falcon 9 block fives and let's say that in some occasions it's being a bit traumatic right but but yeah cuz it's like oh they're expending it what and and then all like uh 46 it was actually the opposite it was like oh that's a cool expending of of this Boer cuz it was on info test they actually exploded the wer on purpose so yeah that was a fun one um yep and yes to all the people screaming at me yes there is one as well in Hawthorne at spacex's headquarters uh I have a picture I have a picture of me underneath it yeah that's an early one that was the first landing I believe which they then decided to clean the S off of it and regret it to this day they actually painted over it and recently they they painted over it again cuz it was like five or six years already on this play and and they were there for like a few months painting it and and trying to get it more I don't know looking more Wier or something I don't know but yeah it's also near the coast to be fair so it's probably a bit Rusty as well yeah that's what happens on the worst Coast I mean West Coast sorry there there's no one here to defend the West Coast so I had now now I'm looking at chat in and someone says the highest tier of membership should include access to the spreadsheets oh that's actually not a bad idea oh uh Anonymous promise anything we do have Anonymous with the store message saying can you please say hi to my son Troy he's a channel member and obsessed with Starship well hi Troy thank you for watching thank you for being a channel member for all the love of Starship which obviously we all love here too so happy to share it with you now the the question I was going to ask before I got distracted by Kevin's comments there was um it was asking let me see if I can find it again um they were asking who's piloting the Drone ship the for just read the instructions I know it is a drone chip but who's actually steering it getting it out there and bringing it back well for for the so for the landing obviously no one is on the Drone ship but they have a recovery team that after the landing they send remote uh signals to the booster so it's saved and everything but in between they have a tug I believe for this one was Signet warhorse 2 I believe is the name uh or might have been the other one they they Ed like two different tugs then Bob and dog also can can be used as tugs although lately that's not going to that's that's has that hasn't been the the norm lately um it seems like they have had uh issues when they have used the fair recover vessels as tuck boats but yeah the the Drone ships there's this thing of them having thrusters big enough to be able to pull themselves out to see but they don't seem to be using them cuz they have their own tracker system they they have the tugs also they have their their own truer systems and we have never seen at least so far the tugs like going away and leing the Drone ship Beyond itself uh that is that is something that hasn't happened yet I believe but maybe gav if he's maybe watching he could he could correct me uh cuz he's the boat guy I I know about some some of the boats but I'm not the boat guy by the way you are correct it is signant warhorse the third oh the third okay I was I thought it was the second okay okay but yes uh that left around about the 16th I believe along with just read the instructions for that oo taking a good look on board now uh we are getting that much closer to the ignition again of that engine for one final burn before deployment of the satellite so what is that kind of like venting that's coming out the top of the engine there yeah that is the oxygen bleed line on the on the on the in back engine what they're doing right now is they're uh chilling down the engine sort of the same as we talked about uh when when they do the liftoff portion it has been in space for like 15 minutes coting right so it has its temperature is basically not the same as the one that it was when you flow liquid oxgen through it so they need to chill it down again in order to prepare for that burn in just a few minutes from now and that is sort of why when we see that blob of ice coming out from that pipe there that is uh a blob of of solid oxygen uh a lot of people think oh it's the condensation from the tanks that it that has fallen down sometimes there's a little bit of ice that does fall down there but it's very unusual it's mostly that solid oxgen from the oxgen that is being uh played out of the of the engine right now during during that uh that portion of the of the flight that we are right now so yeah it's a maybe we see it later before the deployment of the the satellite where it's like this Big Blob of ice it's always cool but in the meantime it's snowing oxygen yep that is still so cool to see yeah and you see some of the chunks of it flying by there little piece so this is all normal and expected and yeah but uh don't stick your tongue out and try to eat any of that snow yeah I'm looking to to that that's the of ice that is growing there on the side of the mvac uh once that engine ignites that's going to be flown out and it's going to be burning on that that exhaust that is always so cool when when it's like thrown out and you see it going through the exhaust and you just push I don't know how to explain it you see you'll see it about a minute or so yeah these icicles are good the uh urine cicle that appeared on a space shuttle mission not so good yeah that's not yeah which did actually happen and maybe we'll bring it up on the upcoming shuttle Sundays which be there or B Square Sunday uh 2 p.m. Central 3 p.m. Eastern starting off this week with sts1 little Shameless self- promotion there plus people can now Mark shuttle off on their bingo cards we are getting that much closer as you can see on the bottom to the SC2 that is second and engine start number two the ignition that we were just talking about and a reminder this is to place the vehicle into a geostationary transfer orbit which means the satellite itself once it's deployed will actually maneuver itself into its final orbit right mhm it has it own its own propulsion and own tanks and everything to be able to to move itself to that final position also interesting that you can kind of to see the speed dropping a little bit with the oxygen venting but that should be going up again any moment with that sh fre light here comes and off it goes that ice getting destroyed by the exhaust there got to love that I love it uh of course the video feed drops out there just as the ignition begins you can see how the how the orbit changes yeah you can see that blue line there that was moving as it showing its actual current path the speed in the bottom right increasing and everything glowing a nice beautiful Orange it's orange there it is I was waiting for that continuing so far with the burn as mentioned it's about a minute long so probably about 10 seconds or so left yep we'll keep an eye out on it so far everything looking good now at 35,000 km an hour and continuing to climb in velocity there and we have SEO 2 second engine cut off two that is the final planned burn of the Merlin vacuum engine for this mission in terms of deploying the satellite we will likely see it have one more ignition to intentionally destroy the rest of the second stage to prevent more space junk right no h this is this is one of the weird ones that actually doesn't cuz for G stationary transfer orbits it tries to actually Reserve all of its performance and all of its propellant to be able to push the satell that you see there all the way uh closer to the G stationary orbit cuz uh you also have to take into account that if he did any sort of uh deorbit burn it will have to be at around apley which is 6 hours after after this burn so it will have to take a long time to do all of that and so actually the second stage what it will do is vent whatever residuals remain on the tanks it'll drain its batteries and just stay passively in this orbit uh until so the the pery the lowest point of this orbit it is low enough uh that it can sort of feel the drag of the atmosphere So eventually it'll come back down to to the ground within a few years and so but but it will stay in this orbit for these type of missions the second stage does not Target and control the orbit for stolic Missions they have plenty of performance to do that it's closer to home it's a lower orbit so they can do that but for these more high energy orbits it doesn't happen that way we are actually working on a video about that by the way U just saying um stay tuned yeah we there is a basically a agreed upon rule that all satellites and vehicles that launch need to have some way to to keep thems out of other people's ways again it doesn't mean everyone always follows it but it's supposed to so the typical three ways that you see are uh intentionally burning itself up in the atmosphere by firing its engines into a d orbit eventually letting the force of gravity take over and have it burn up like this one once it the Pary gets low enough and then the third option typically is a graveyard orbit where there are specific orbits that is meant just for dead satellites and stages to kind of stay there and be out of the way yeah like see for example this satellite right whenever it it is its end of Lifetime right which maybe 15 20 years from now we we cannot leave it at the same orbits as the other satellites are in G Station orbit so what they do is they leave a little bit of Reserve propellant on board to be able to push it slightly higher I think G stationary like the graveyard Orbits for G stationary orbit are like 300 km above the the belt of G stationary orbit so they they raise a little bit that orbit and clear it away from the rest of the of the satellites to not have a lot of junk basically on that on that belt so yeah exactly yeah it it lowers the risk of a satellite accidentally crashing into it with it not having any control there uh it also makes room for newer satellites that are actually functioning to go into geostationary transfer orbit to replace some of the defunct ones mhm yeah we are coming up very shortly on the deployment of this spacecraft here as the vehicle now more than 590 kilom in altitude uh I do want to shout out here uh sarin thank you for getting an item from the store saying a fine addition to my collection robotic wheezing getting the new patch and then Bob Thomas saying I live 150 M South I watch you guys and then when it launches I step outside thank you well thank you for watching and is that the mo near the in back oh yeah look at that and of course they cut away bye eyes but yes uh thank you very much for that Bob and it's someone who's also about 150 Mi South you can still get quite the view from down here so how exactly does the spacecraft separate which we should be seeing in about a minute or so what's the mechanism to do that normally what they use is like a spring system where it just you release the spring and the satellite just is pushed off by that elasticity of releasing the spring and so you probably will see that to the right here if they keep that view the you'll see sort of that spring system popping out and the the salite is is pushed out um so that is usually what they use for this kind of separations so let's keep an eye out for that on the right side of the screen there it should be deploying any second now there he goes there we go maruti 2 now on its way soon to be in geostationary orbit at an altitude of about 800 km up at time of deploy that is unbelievable and beautiful view that's another happy customer yes another suia yep mhm uh everyone clapping yay yes all the claps in chat too yeah everyone clap yay you can kind of see sort of the the Lamb of the earth back there on on the bottom I don't know if you if you can see it cuz it's during the night obviously but you can sort of discern it on the on the lower left but anyways yeah there we go yeah as long as we can have this view take a look at that off into the darkness it's also fun comparing it to something like uh Nova CA and that deployment mechanism so as we go from space to back down here on Earth I I want to thank everyone for their absolutely generous and fantastic support during this Mission and of course I want to thank the people that were with me here today uh no longer on comms but Max Evans who's out in the field providing all the tracking cameras which we'll get to show you some of those replays in a little bit fantastic work and also fantastic work from you Alex thank you very much for co-hosting with me here with your amazing knowledge and spreadsheets it's been a pleasure and of course a lot of clapping also for for Max for those views yes keep the claps coming for Max and then we had Patrick behind the scenes pushing the buttons pulling the levers running in the humanized hamster wheel or whatever else what other whatever other wording we come up with there but helping to make this all happen so huge shout out to Patrick thank you very much as always and thank you again to everybody who joined us here today stick around for final launch replay here and we will see you again on the next launch coming up very soon so stay tuned for that keep up to date with those launches at next space flight app I'm so Rosenstein I have been your host for today have a great one [Music] [Music] and here we go we have propulsion continues to be caral R 68 chamber pressure looks good probably not water tower [Music] fly go [Music] down orange oh my God oh my [Music] God put that in the big bag 343 unfolds to go indeed we rise together back to the moon and Beyond if it was messing it be igniting in the flare [Music] correct we don't need anym these
