SpaceX Rolls Out Ship 28 for Third Starship Flight Test Campaign

and here we go we have LIF off propulsion continues to be noral R 68 chamber pressure looks good probably not water tow fly yes he go down pH nominal [Music] it's orange 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 me it be exiting in the flare correct re we don't need any more of [Music] these good early morning here from Starbase even though it is 1 a.m. in Texas we know that tank Watchers never sleep I am Sawyer Rosenstein I'll be your host this evening as ship 28 rolls out on its way to the launch site so we've got some excitement happening and of course I'm not the only one excited and that will be joining in on the excitement that includes my co-host which tonight is Trevor snic Trevor how's it going you know as I said yesterday whenever we see flight Hardware going to the pad it's easy to be excited so this is hopefully the last roll out of ship 28 before if3 so I'm doing pretty good darn good I already see a drone flying in the air you know it's going to be a good night and also joining us tonight is Ryan Weber Ryan how's it going oh dude fantastic soer how are you we got a got an awesome uh stream ahead of us here ship 28 rolling out can't wait for flight three it's finally feeling real with uh booster 10 now on the orbital launch Mount and ship 28 rolling out to the launch site it's getting real it's getting real again I love that excitement so we are going to be tracking ship 28 as it rolls and of course answering your questions along the way so a reminder if you have any questions you can tag us at NASA space flight and we will do our best to answer as many of them as we can tonight so uh I was kind of just asking this a little bit before we get started I guess the question now is the launch campaign here so ship 28 heading out to the launch site you think maybe suborbital pad b or we go in full send here you think uh Ryan I'll start with you uh I think it's going to the olm I mean the the a lot of people have been speculating on whether or not we'd get a static fire or not since they might have replaced some engines but as we've said in the past couple of streams we don't actually know if they have replaced engines um they may have just taken off the ones they had on done something to them or they took the engines off to get access to the apome a little bit easier that's Pro could be one of the things they tried to do um we'll just have to wait and see where goes and that's that's what all the excitement is out just wait and see with this program exact I mean yeah that's pretty much Starship in a nutshell right there is honestly wait and see and it's always excitement for sure uh so in terms of the role itself tonight uh getting out to the launch site at least uh Trevor what does that involve here yeah so this is pretty typical at this point now that SpaceX is quite familiar with this operation uh as they they done this a lot of time so uh we'll see them roll on the spmt uh out from the production site and just all the way down the highway to um the launch site and this on in general takes about 45 minutes um there have been times where it's been taking longer like I know Sawyer we've had wonderful nights stuck on stream together when an spmt breaks down um but hopefully none of that happens tonight and yeah yeah let's let's definitely hope that doesn't happen tonight uh it looks like they may have been struggling a little bit with uh getting it off of the cranes a little bit earlier tonight but I think that we're on track now as you can see right there in that shot on top of the spmt behind those Bright Lights of the police cars there uh here's an interesting question from Eileen saying do you know if SpaceX has designated night Crews and day Crews or they just designated for roll outs I don't think we know exactly but we know that Starbase is 24 hours right Ryan uh yeah star Starbase runs at pretty much 24 hours they mostly get like uh Sundays off these days it's not like back in the old Elon days when they would be pushing hard for a launch where you'd be seeing them work almost non-stop every single day of the week they get uh they pretty much get Sundays off and you know Saturdays are are a lot slower um I know they work in shifts and there are specific teams that work on shifts that work on the ships themselves and their teams that work on the boosters um there's specific people who deal with the cranes who deal with the spns so they definitely have specific people for specific things um I don't know if like they plan on when they plan on doing a roll out if they actually call a team in to do that I actually don't know if they do that or not or if it's just who's on hand that night gets taken care of it so there you go and I mean you always see the one you know the people that are watching as it does the turning and my favorite part is you know when you think back to at least for me for the old shuttle days the person in front driving as the uh shuttle gets brought over from the orbitor processing facility to the Vehicle Assembly Building Trevor here it's it's like a joystick it's like a video game yeah it really is um you know this is one thing that we've seen SpaceX do over and over uh where instead of Designing some really expensive Machinery to transport uh these vehicles they just see like what's out there and see if they can modify it to their applications so um spts you know they're not super common but they're also by no means uh exclusive to SpaceX and the Starship program they're used to transport all sorts of large U Machinery uh so with that it's just a little control box and like Sawyer was saying it's basically just a control stick that they use uh to to uh roll this what 70 M tall vehicle down the road um which is pretty awesome and that must be a pretty cool Flex like oh what did you do at work today oh I took the Starship for a walk or whatever they say yes this is the the best part where you get to say you take your uh ship for a walk it's a good workout too you just uh when when they're just driving the spms around just on their own without anything on them or if there's small things on them there's a chair they can sit in right next to the power pack in the back and they just kind of ride along with it but when they do large transports like this they can't really see around that so basically the guy just walks in from behind with a remote control joystick and just moves the spns in unison as it goes down it's pretty cool so just watch them do that we'll also have to see what beverages they may have left on the back of the spmt for them to drink cuz they drive down Highway 4 uh what did we see we've seen some Gatorade in the past we've seen some sodas so who knows it it's the fun little things about these I mean the role itself is amazing but it's all the fun little quirks and you know the the time when they dressed it all up for Christmas that was still one of my favorites too yeah Trevor was there for that me and Trevor for there for that stream that was fun yeah that was ship 208's first roll out right right after3 yeah that was its first roll out with all the Snowman the Snowman the lights the Christmas trees all and the Santa uh it was kind of funny someone had uh tallied it up all of it was from Home Depot apparently and someone had Ted it up I think it was it was like like a couple thousand dollars or something along those lines of lights and just stuff or something along the I think it was that much it was I wonder who made that Home Depot trip to do that yeah uh what' you need uh every single holiday decoration you have how big of a tree are you talking yes yes you have 70 meters yeah oh boy anyway it looks like tonight the only lights we're getting are the blue lights from the escort in the front there mhm Oh I thought Starship got pulled over for speeding uh that' be funny yeah the spmt does a hole whopping what 3 miles an hour I believe is around the top speed I don't remember what they can do they can I'll actually here let me let me look I don't remember off top of my head yeah it's about three miles an hour um which I know Sawyer's about to bring it up so I'll beat him I believe the shuttle uh all of those mobile platforms moved at around 2 m an hour correct or uh so it's like 50% faster than those which it may only be 1 mph but it makes a difference wait wouldn't that be 1/3 not 50% Mr math well 50% more than two is three okay fair enough I I thought yeah that's why I'm not a math person but yeah the top speed of the crawler transporter is 2 miles an hour it's typically about 1 and a half when it had an Orbiter on top and uh once it got to the incline at 39a and or B uh it slowed down to about a half mile an hour and uh thank you Kevin that is very true Sawyer does not math and apparently now randomly speaks in third person again Kevin Michael Reed yeah when empty the spts can move uh 10 kph when fully loaded it's 5 kph so yeah like 3 miles an hour that's still pretty good yeah considering it's these two spns are hauling 150 150 160 tons give or take it's hard to really know what the weight of Starship is these days probably somewhere around there and boosters or 240 250 o and you're not just talking the way the vehicle too you're also talking the counter balance as well and the transport stand yes like I mean the booster transport stand got way beefier uh which means as as I don't know if you guys have noticed especially since with with the last roll out but there's less counterweights off for booster moves now because well they made the booster stand heavy enough that they needed less counterweights which helps in the long run there but yeah I would say that's counterintuitive but it's actually not oh my gosh oh Sawyer it's too late for these oh come on I I so do you want me to start I did see a viewer question asking have you uh brushed up on any of your movie knowledge since last night um I have been doing model Theory homework all day so if you have any questions about model Theory shoot them my way but about movies I don't think I'm your guy questions about movies you can probably ask me or Sawyer can probably answer a good chunk of them don't even ask him what TV Guide is although he may know now but anyway uh I do want to thanks some support before the stream even started we had Tom gifting five red team memberships airor attac gifting 20 red team memberships very nice thank you so much and Joy Ride becoming a launch director Member One of the high levels there of support which we really truly appreciate so thank you it's because of this support that we get to have all these cameras running 247 and deploy out the special ones for uh you know these rollouts it it's really fantastic so thank you uh along with Christopher saying breakfast time in Norway and this just completes it h normally with these they end up being lunchtime uh roles here in the US at least uh and then Sheriff Tracy thank you for gifting a red team membership love seeing that name in chat as well now I've seen a couple of questions about this um they're asking about the removal of the engine that we saw previously on ship 28 uh do we know if it's the same one that was previously static fired before if they fully replaced it if it's a new engine number what do we know about that engine replacement Trevor yeah unfortunately not a whole lot and like Ryan was saying at the start of the show we don't even know if the engine was replaced uh it's very possible that they may have just removed the engine done a little bit of work on it and reinstalled it or as Ryan said maybe they just needed to access something behind the engine um so I think we'll probably get a good indication of that tonight uh if ship ends up rolling to suborbital pad uh we can assume that it'll conduct another static fire in which case I think it's a good indication that they did work um or they either did major work on the engine or it's a complete new engine alternatively if it goes to uh the orbital Launchpad uh then you know one could possibly make the argument that they didn't uh do any significant work on it uh but that's all conjecture uh so hopefully we'll learn more at some point from Elon or other SpaceX Affiliates it's that's the Hope because the other part to that too is um we're still we still don't really know when when the FAA will be ready uh or even SpaceX will be ready cuz I mean they're they're still scaffolding on the olm and on the QD arm so they're still not ready themselves and what they could do is they could roll it to the orbital Launchpad do possibly a wet dress um or whatnot and then they could daack it and then they could roll it over and do a static fire with it that's en entirely within the r possibility um so especially if they have the time so we'll just have to wait and see uh what they do and if they do stack it uh hopefully we'll get to see the serial numbers of the engines as then that'll give us a clear indicator whether or not they uh they changed them out or not because we've already seen which serial numbers have gone in uh cuz thanks to Jack and Shawn were able to capture all the numbers before uh SpaceX closed remedios so and my thought on the whole thing with that would be we've seen it in the past where they have done uh booster and uh ship testing basically the same day within hours of each other of I know wet dress for sure and I think it was actually a static fire they had two in the same day uh I could see them doing something like that again they do have the time but it's SpaceX they like doing things quick and as you know why not do both while you're at it kind of deal I could see them rolling it out to the suborbital pad and then having a static fire of uh 10 and 28 within the same day yeah my thought and one thing that you know is important to keep in mind is even though right since the last launch was in November it'll be on the order of five to you know 4 to five months between launches that doesn't mean that SpaceX may not want to demonstrate that one once they have the vehicles ready they can get into a launch position really quickly and some of that may uh involve doing some very uh or uh backtack tests really quickly and I don't think that would probably include a static fire in that situation but it may include say like we saw last time a mini wet dress into a full wet dress or rapidly stacking getting into position for wet dress or her so or something like that so I wouldn't be surprised if we see SpaceX even if they don't need the time really trying to get these events done as quickly as they possibly can or even throwing a spin Prime in there that would be fun as long as it doesn't repeat what we saw in August of what 2022 yeah let's not repeat that they fixed they they have definitely learned from that lesson and fixed a few um fixed a few things that was July 11th of 2022 is when that that lovely explosion happened happen um they they definitely learned their lesson as to not let methane build up under a vehicle while it's and then introduce a bunch of liquid oxygen to it methane ignite in the flare stack if that would be methane it would be igniting right yikes you bet there we go we don't need any more of these um uh here's actually a really interesting question kind of going along the lines with that uh James here is asking do we know when SpaceX will put that fancy cladding on the towers that we've seen in the renders cuz I mean Ryan it looks like they've been adding additional cladding as is especially with all the scaffolding still up any thoughts so they haven't added anything to the ship QD arm or even up this up the tower what they've been adding is basically large Steel Ste plates to the concrete of the base of the tower cuz um before before they added all those if you go look back to pictures all the two flights plus all the static fires really started to erode that concrete away and they realized that they need something more to protect it so they added a bunch of Steel plates which will just take the brunt of it at this point um I don't know if they're going to add that clading maybe that's something that happened s with the next launch Launchpad um it' be kind of cool if they did the whole if they did the whole thing like the renderings and made it painted it all black like the FSS at uh at 39a um I don't know if they'll do it it'll look cool but I don't know if they'll do it or not I mean yeah I wouldn't put it past them because Aesthetics even over at pad 40 the same thing you've got that really cool black and white aesthetic with the crew access arm now so why not make it practical and stylish I guess that goes into this uh very generous support that we also got not from Kevin Michael Reed but from Michael Kevin Cil uh with a $50 Super Chat saying is a second olm being built or do you think the second tower will be just for practicing catching it first appreciate all yall do and your amazing coverage also model of theory sounds fascinating so Trevor will get this one to you because of that but well let's start with the Starship part first second being built do you think it's just for catching at first or full-on flight right away no it'll be for full-on flights uh almost certainly it really wouldn't make that much sense to build a whole second tower uh purely for catch attempts because uh right the two things that you want to keep in mind is that uh first of all they'll be landing thankfully not over the orbital launch ring um so in theory they should be putting the ring under minimal um risk of damage then on top of that at time of Landing there won't be that much propellant left on the vehicle right in fact you want your um propellant res residuals to be as little as possible um so between those two things you know there'll obviously be a lot of energy in the vehicle but there won't be a lot of like potential chemical energy that could cause it to go boom and uh cause uh damage severe damage to the launch sign um so I think I just got to say really quick I'm sorry to interrupt you but this thing is moving fast as it gets closer here to us uh as ship 28 rolls out sorry I just had to point that out yeah so this is actually we should briefly talk about this we'll soon get the really cool shots uh of the new heat shield um that we see which does to me look a little bit better than what we saw on ship 25 and ship 24 and then also if we get lucky we may be able to peek up the skirt and see those uh six Raptor engines so you can kind of see the middle three right now those are the sea level and then on the left uh there's one of those nice Raptor vacuum engines yeah also don't make call HR for looking up skirts I I can see all six I see the arax and that unfortunately I don't think we can see serial numbers get out of the way light I was going to say it's tough at night yeah yeah p h that light is like not helping no I think we could have almost seen a serial number on the center right there almost had it but the light was was kind of just was kind of getting away camera it's moving away from the light let's see what we can see now maybe not no I think the stand is in the way at this point yeah we'll have to see when they uh when they stack it what what we can get but it does have all six engines again so there there is that yeah that's a good [Laughter] start well while we're here I do have a uh question about this I don't know if either of you know the answer but are the tires on the spmt pneumatic or forklift style solid tires do we know I have absolutely idea a nice good closeup of them driving by my conjecture would be solid rubber cuz yeah yeah but yeah it appears almost tank Style with the Treads there so sorry it's just mesmerizing still watching this giant thing Roll by and it feels like someone's playing in a fast forward like in the intro but no it's that this is just normal they're getting good at this uh that is very true so what are some of these trucks behind it yeah uh that is the pressurization truck behind it to help keep the vehicle pressurized and whatnot and stuff yeah to add a little extra rigidity and strength as it rolls down right they don't have to do it to uh to the boosters anymore the boosters have more than enough stringers and structural Integrity To Roll without needing press lines on anymore um and the uh the ships well they've been able to add enough structural Integrity to to where they can go inside the tanks without having to hook it up to a crane which is a big bonus over what they used to have like if you go all the way back to like ship 20 and booster 4 or even heck like sn9 uh in order to get inside those tanks they had to hook up to the crane cuz they didn't have as many stringers on inside um so yeah just the evolution of the vehicles themselves and the support it's just it's amazing how much the vehicle has changed let's even from uh booster 7 which I know right away they're like well we've already made improvements for booster 9 but we're still going to fly seven anyway but from 7 to 10 is quite a lot of uh improv thank gosh those hpus are gone yes thank electric TV electric yeah just as a viewer I got sick of it felt like every other week they like fried an hpu and they're being sent off for repair and it's like oh my gosh yes electric TVC FTW okay uh while we see it Rolling On by there uh we've got a couple more support that I want to hit here Jim Chapman thank you for becoming a Capcom M reminder Capcom and above gets access to the NSF Discord and pictures of Jack's lunch um I promise there's better selling points than that uh James CER asking hey Trevor Who's Sean connory uh he was the one who is really bad at playing James Bond whoa okay whoa I I heard a disconnect sound and I thought that disconnected me yeah server mute you or put you down into another room where we can't hear you I mean in in all seriousness like I didn't think I I've only watched one of the old James Bond I think it was it was the one where they like robbed the um national uh treasure um Fort Knox I think Fort Knox yeah and I don't know it was just like too unsophisticated for me to enjoy that said I do really I have really enjoyed the ones with um uh who was the latest Bond Daniel Craig Daniel Craig he is such a good actor spoiler he's not bond anymore but yeah yeah the last Bond was good uh it goes along with Brendan Brown who saying did Jack sent Trevor back to school after yesterday's lack of knowing what things are in this world yeah I got yelled at don't worry oh boy uh the nerdy one 9:00 a.m. in Romania perfect breakfast stream yeah we getting uh Europe waking up here which is really nice so uh good morning to those who are and uh you crazy night owls in the US that are still awake I don't know what you're doing but you've joined the cool stream what are you doing it's like almost 3:00 a.m. for you yes it is I'm a night owl and an insomniac so why not talk about starter ship right uh and normal time for anyways yeah bford coming in with the generous support as well saying we need the wake up puns from Sawyer to keep us here in the states awake keep them coming absolutely oh you asked for it fair warning hey I don't mind them they're funny oh go oh um all right here's a question while we were talking about the Chopsticks I do want to go back to you know the second tower things like that uh we have a question here from Deborah asking will they try risk will they risk trying a chopstick catch before they have a second orbit a launch Mount operational cuz I was hypothesizing earlier during NSF live which is now 700 p.m. on Fridays Eastern um that they might be building the second tower so that if something does go wrong with the catch on the first Tower they have a backup but Trevor what are your thoughts do you think they would try and catch before they have the second tower done yeah I think if um you know on this flight they are able to successfully demonstrate that they're able to make it through re-entry of the booster uh and demonstrate controlled splash down in the ocean um like I was saying a bit ago there's not that much risk uh right the worst comes to where he may damage your Tower a little bit and the Chopsticks and whatnot but in the grand scheme of things you know that's nowhere near as complex to build and replace as uh the orbital launch ring itself um and all of the GSC surrounding the tank farm um so I I don't think they'll shy away from it especially because they really need to um if they want to start increasing launch Cadence Beyond you know a launch every two to 3 months uh they'll really need to start reusing uh these boosters because they take so long to build and they're so complex um and the other thing to keep in mind is this second orbital launch Mount minor standings are going to need to do fairly significant reviews again uh so need to go through fish and wildlife service and um some of the environmental uh legislation that they had to go through for the first Ora launch site all over again so it may be a little while until they're actually able to use that pad yeah all of that should be covered under the current PA paa I'd have to look at it again but I'm pretty sure they can still do that under the current one um there may be some modifications here and there they need to make to it but it should be covered cuz like the uh the whole fish and wildlife thing on the water Deluge will still apply to that pad once it's built it'll just have to be applied for that slightly different location um the the biggest issue is depending on where that pad is built so if they build it say at the suborbital side they can pretty much just build it because they don't have to go through anything with the Army Corp of Engineers a public comment period or anything along those lines in order to get it built now if they go to the South they have to get approval from the Army Corps of Engineers to take a section of land out of the wetlands that then that Wetlands basically has to get replace somewhere else um they kind of have to like acre for acre replace it somewhere else and then that enters a public comment period it's like 30 or 90 days uh where people can give their public comments on the plans to do that specific setup and then they can go ahead and build it so there's extra steps if they build to the South compared to if they were to build behind the curtain pad so you're saying if they ask if they can build to the South the response is Go Fish pretty much no one okay that's fine um along those lines I think the silence is sometimes funnier uh so while we're talking about the fish people Captain McLaren's asking I'll put this one over you Trevor who's responsible for issuing the safety notices before all these launch site activities that we're seeing here who's the land people yeah so there are a bunch of different um departments that uh go for these notices depending on what testing they're exactly doing so for these roll outs where um they just need to shut down the road for a little bit and there's no real danger to anyone right I mean there are people walking right next to the vehicle um they just need the uh Cameron County to issue a road closure to them um then there's a 24/7 standing TFR that comes from the FAA uh and then the Marine H Hazard zones all come from the Coast Guard if I remember correctly uh so there's there's a lot of different agencies that have to come together especially on a launch day where they need to make sure that the land is clear that the sea is clear that the air is clear um and that the village is evacuated and all of that so it's a lot of different departments that come together it really is so I mean you can always check the road closures that we get but there's so much more that goes into it for all the rest of the testing too yeah uh let's see here another question that we have here from Noland asking is there a payload inside ship 28 or does it even have a Pez dispenser Ryan uh there is not a payload inside and yes it does have a Pez dispenser it has a working one I might add the door also works uh this is a newer uh payload bit design compared to 24 and 25 where those doors were welded shut um this they actually were doing some uh door actuation tests after the static fire uh way back in um way back in what was it December at this rate been that long a long time well Che yeah back in back at the end of December um yeah so my guess is they'll go ahead and try to test that system uh during the flight uh just to see you know how it works in Flight in in a vacuum that kind of stuff I don't think they're going to be loading anything on board um if they were going to do that they probably would have done it in the high Bay I I don't know if they have the capability to load it cuz they haven't used their starlink box in like a year and a and a half or something like that and the satellites in that payload processing facility aren't really very usable they'd be usable as a dummy payload to just reenter but that's all they're really used useful for yeah at this point they're those satellites are over a year old it feels like the and then or more than that even I think I think some of those V2s were even from the like original Tim tour like 2 years ago or something like that it's been a while but they've also they haven't really been in a clean room like they've been exposed to dust and particles and they're probably if they were once operational they surely aren't anymore yeah and if I recall even the building that they were being housed in which wasn't super clean is now torn down and is already serving a different purpose now I believe for welding of some kind so well the the building is actually torn down uh if we if we go back to that shot um real quick Patrick well this is the good part of the rooll we'll get to it okay but we can go back to the shot that was before you could see the payload processing facility still there but they kind of yeah the white building right there that's about to pass the big one uh they kind of keep it for storage and stuff right now and there're still sat still held in there but that's that's about it now yeah yeah thank you for cutting back like we've been saying the SATs are um very out of date at this point uh those were there before SpaceX launched even any of the V2 mini satellites and I believe when those satellites were there we didn't even know that V2 mini was a thing um so that's one goes to show how ridiculously quickly SpaceX developed those V2 mini satellites um but also just goes to show that um outside of getting data from Starship um uh in terms of deployment they wouldn't be that helpful um so I don't know we'll we'll have to see if V2 ever gets launched on Starship because I wouldn't be too surprised if at this point they would be ready to just launch like V3 or whatever yeah I could see that and again it we have the operational payload Bay finally it's just a question of when they'll actually decide to use it uh again right now I think the priority as they mentioned for this one is going to be the fuel transfer and oh yeah completing the uh full flight trajectory Minor Detail as we see ship 28 continuing its rooll out to the launch site here with these awesome up close views I I love when you get the people for scale as cool as bananas for scale are there's something about people for scale that's also just really cool with vehicles like these again we're talking the vehicle itself is about 70 M and that's not counting the extra height from the spmt here well this one is 50 chip is 50 booster is 70 so so it is about 70 with everything combined on this is what I meant yeah yeah give or take and maybe maybe around H maybe around 60 I I'd say 60 total or maybe 55 60 somewhere around that range either way it's tall it's it's crazy that it's almost as tall as Falcon 9 which is a very capable rocket and it's just the second stage this is the second stage of it that that's just a payload deployment mechanism in this case yeah basically yeah and this is the shortest to ship will ever be like right elon's on many occasions talked about um lengthening the ship a bit and it seems I don't want to say probable but uh possible if not likely uh that the Starship V2 variants which we're expecting uh to be in what three or four ships from now we're expecting those to possibly be a little bit longer um based on a pretty vague tweet that Elon post or post Elon made on a well it was the um the All Hands meeting that he had he had mentioned that V2 was basically going to be like reliability improvements or something along those lines and that V3 might be the one being stretched now but you know Elon just likes to make up numbers these days um and I'm think I think V2 will be the same height they may they may end up making it taller but I think the biggest thing with version two uh revision the next revision I would say which is looking to be ship 36 or 37 at this rate um will be it it's just going to be more reliable it's got a lot it'll have Plumbing improvements valve improvements engine improvements shielding improvements probably improvements to the heat shield you know just small things here and there that they've learned over the course of these orbital flights plus the orbital flights into making much more robust and uh more reliable vehicle going forward head over get the potential of adding more engines now too oh yeah three more three more racks would be nice to see yeah that's very nice so we get this very nice closeup look now kind of looking down at the skirt area where the three Raptor seil three Raptor vacuum under ship 28 she is a be I'm just enjoying the The View I apologize for not asking questions for a moment here if you guys see anything that jumps out to you as you're watching it call it out please you know you say that 28 is a beauty but I I still think the ships by themselves look kind of horrible to be honest especially the back of it you me the part that we zoomed in on yeah well let's listen to the sound [Music] [Music] good decals here little spmt ASMR for you just waking up or trying to fall asleep in the US and there's the payload Bay of 28 that Ryan was talking about a little earlier it almost looks like it's flopping in the breeze oh it's got door locks on it is what it has those the red things are the are the locks for the door so make sure it doesn't move and it's not supposed to all remove move before flight uh I would hope yeah again it's we still don't know if they're actually going to use said payload Bay dispenser in flight but at least it's it's there I would guess that they will since they finally have an operational one they'll want to test as much as they can with all these vehicles which that goes along with the question that we got here from Jamon nose saying do we you think we'll ever see a Starship with a shuttle like payload door Trevor what do you think in terms of the future of pale bay doors besides just Pez dispensers cuz let's be honest we're not going to be able to deploy an entire space station in a single go from a Pez dispenser yeah um shuttle style I don't think so um R shuttle had the advantage if you will of having all of the uh crew rest areas and cockpit and all of that up front um so dur in the pointy section of the vehicle they were kind of able to get away with it not being usable payad space but on Star set when that's not the case uh you kind of want to be able to take advantage of that volume as much as possible um so I think we'll see more of the chomper style door as we've seen in renders before at the front of the nose cone uh and then POS probably be able to like tilt the payload up to push it out a little bit um but this will be very interesting to see because dealing with a door design that is able to uh survive re-entry is definitely not an easy engineering problem then again nothing on this rocket is easy no well said uh we have Gordon row who became a pad rat member we had who also gifted a red team membership thank you very much uh F Haman I I'm saying that right thank you for gifting a red team membership uh that go that guy pointing out it's the speeding it up and slowing it down that's the tricky part yeah constant speed is one thing stopping is a whole another thing uh which goes along with a question from that guy while we're at it saying uh how do they stabilize the vehicle on transport Ryan do you want to take that uh so to stabilize as it's rolling as you can see they have counter weights on it which helps alleviate and keep the center of mass as far down as possible because the ship still weighs a decent amount up top with the nose cone header tanks and everything like that um and then along with that the spmt are self-leveling so uh kind of like the crawler transporter uh that's used for SLS shuttle and was used for Saturn um the spns can selflevel themselves to to keep whatever they are transporting level uh which helps make sure things don't tip over cuz from this angle it looks like it's leaning backwards but it's obviously might be the road yeah or the camera it's it's level cuz I know there were people that was like well this thing's leaning back quite a bit it it it's just an illusion uh Blackhawk thank you for gifting five red team memberships Sheriff Tracy thank you for giting another red team membership uh and then averto coming in with two generous supports here the first one Trevor are you scalan I don't know what that means let me look this up I hope this is a safe search oh man and while Trevor is saying that I just want to thank Shawn for putting out cp11 for us so we could get get those awesome views as was coming down remedios um yes so yeah shout out to Sean great work sea with that and uh I know he'll be back out for the full lift as well so get some good sleep so wikip it took me to a Wikipedia article about winking like the wink of an eye so I have absolutely no idea oh that's a Star Trek episode oh oh yeah wow that's a call back yeah um anyway with the second message which uh I would hope you would get this one but they say uh to me roundabouts are never straightforward that's a good one I like that that's a good one yeah a good one I mean while we're talking about the payload Bay when is a door not a door when it's a jar nice thank you I wouldn't be surprised if Patrick just UPS the volume on the spmt sound to drown me out from more of those I wouldn't blame him I don't think he can it's not near a mic so you're going to get away with it uh Aaron CH thank you for the support and there it is and I'm hillan uh at asking doesn't the rust that ships and boosters are accumulating compromise structural integrity that's a really good question cuz keep in mind that you're right along the Gulf of Mexico here but at the same time with all Falcon 9 that's also right along the Atlantic there and they're the ones that are landing on top of the Drone ships so Trevor what do you think yeah it absolutely can um right there's the I think we all have the image in our head of like a Jung car um after it's been spent some time in the um like outside where it just is rusting and falling apart um so you know the chemical reaction that occurs when rust forms uh does weaken the underlying metal um I suspect that SpaceX is probably largely able to get around some of the more structural issues by uh the way that the ships are assembled and for all I know um you know they may have some coating on some of the more sensitive areas I'm not entirely sure uh but also I think that's something you can just get around by um doing enough reviews so long term when they're actually reusing these uh have a fleet of these boosters and uh are flying them regularly they may need to be doing pretty substantial um maintenance on them to make sure that the rest doesn't uh compromise structural Integrity too much but uh Ryan probably could give a far better answer to this question since he actually works in a very similar field so um on stainless steel stainless steel will still rust uh you give it give it enough uh humidity and Salt Air it'll definitely still rust uh if you need any indication to that just look at booster 4 at this point it is not a Happy Booster um now a lot of times though it's stainless steel if you're able to keep it inside and keep it in a controlled environment like um uh like the like The Bays where they're adding the doors it'll definitely help a lot and cleaning it um I don't think they can go ahead and just add cic or corrosion inhibiting compound to it um I work on I work on 737s and when we if we do like a wheel well wash you take a couple of cans of that and you spray a nice big coating inside the wheel well cuz I I mean Starships don't get this dirty but in there you get dirt oil Sky draw you know anything that's coming off the Runway that comes off the tires rubber all gets just shoved in there um I I don't think that's a solution for Starship in the long run um the best they can really do is to try to keep these vehicles inside when they're not using them as much as possible um to keep them as clean as possible and that's really the best they can do to it uh cuz you're when you add that kind of stuff you also add uh you also add more weight to it and I really don't know how a compound like that would interact with the Plasma on re-entry I don't know how that would work out or how that would even work in space for that matter in in a vacuum but yeah pretty much there you go great insight uh Trevor I do want to point out that aack clarified in chat saying it's because you like to play Back YouTube videos at 1.75 to 2x speed oh yeah that's just the correct way to watch YouTube oh God this is this is going to be more of an argument than the best ship here right um also during that uh I had to look up cuz I actually wasn't even you know I I I tried to forget the two chemistry classes that I took in college because I do not like chem um but I forgot that chemistry was or not chemistry rust is just the oxide the oxidation of iron um and then it allows it to react with um uh hydroxide M uh so yeah I don't see how this would happen during reent at all I suspect that um it wouldn't be too big of a problem but I'm not a chemist don't listen to any chemistry I say I'm sorry did you say something I wasn't listening to your Chemistry uh all right I have two really good questions here and I want to ask them back to back as we see it getting closer and closer to the launch site here um Mr Kiren asking what if do you think will be the first one with a catch and kyus with another question here that kind of goes with it how many ifts do you think there will be before the first commercial flight so think of your predictions Ryan I'll start with you I'll I'll start with this so first catch um the real the real question is is I think by the time they catch a booster it's not going to be an if which is Alex's favorite term um it's not going to be it's not going to be if anymore I think it'll be a starlink 10-20 whatever uh for when they do a catch um it it will no longer be a flight test it'll be an operational flight uh and to say that um yeah I and to say the first commercial customer um hm I know Spa I know Starship already has a couple of contracts under under wraps I don't remember them all I don't remember them off top of my head but I I could be I I could see the first commercial customer end of even end of 2025 but the the thing is is it that entirely depends on them having their actual payload Bay built um first commercial customer I don't I don't count starlink Kevin as first commercial customer it's basically internal customer I don't count that maybe it's just me but I don't count starlink as a commercial customer for Starship all right your turn Trevor um how many yeah so if is like somewhat of a non-official name right I think internally the name that SpaceX calls it at least on their website and whatnot seems to just be Starship flight you know one Starship Flight 2 uh and then the emphasis on the first launch was that it was the first integrated flight of Starship and that's where if came from um so in terms of like how many integrated uh flight tests will there be I really have no idea cuz you know I I think at maybe five or after five or so launches they'll start start moving on to um more uh commercial Mi or at least more uh starlink missions and then I wouldn't be surprised if it's like flight 15 or so before it flies a customer outside of starlink and that's purely uh in my opinion uh because as we were discussing earlier the chomp the chomper uh payload Bay will be quite difficult to get working now now I would I guess I could ask this question to both of you cuz then I kind of have this thing myself this year could we could could see if that is if they want to deploy SATs off of um off of their version one of ship uh we could see a starlink mission from Starship this year by the end of the year and it wouldn't be so it wouldn't be called a flight test anymore it would just be called whatever starlink Mission they decid to name it again depends on if they count that as a test payload true cuz if it's their first payload flight test I mean again we've had in the past we've had a wheel of cheese for Falcon we've had uh Tesla Roadster for Falcon heavy so I mean yeah those are technically uh sorry the PA there would it's saying I those technically payloads that they launch but I don't know if you would consider those they're spacex's own things so uh I think this still would be the a flight test and I think once they get that first start that would be the end thank forting that that would be the end of the flight test good morning everybody hope you're awake I guess that's what PA was for according to Alex that was the PA was to warn everyone for loud venting so we got lot of venting oh boy yeah uh everyone that was asleep uh good morning everyone that was trying to fall asleep apologies oh boy okay anyway oh vent away Sawyer is being interrupted by Starship which is pretty rude it's rude rud how [Music] rude yeah that that was uh someone pointed out just went anyway vent looks like it's almost around the bend here should be coming up on the SpaceX sign do I try talking nope I don't the vent timing is just it's too perfect you're disg gracious words try to talk over the venting I think the Vets are telling me to shut up here yeah according to Kevin Michael Reed that's what they're saying I saying Sawyer be quiet I will not be silence no okay here it comes up uh near the SpaceX sign near the entrance to the suborbital site it's coming around the corner that is a cool view to see the I mean it right now it's xaps it's backwards but yeah I deserve a venting after that let's continue oh GE I don't know how you do it you just get like that uh it's something in your brain you're just able to pull those those puns out I I cannot do that I just can't I don't have that kind of the wiring I just don't I don't I don't know where you get that from it's a blessing and a curse it's a b uh it's yeah x x caps x e c a PS backwards okay real questions here uh let's see looking for a good one here uh space I like that space asking how long does it usually take to launch something after roll out I mean sure it's probably going to be a little bit longer here I guess it's different for something like a falcon 9 where they rolled out within 5 hours and launched um well I can give you the examples of the last two flights so the boot booster 7 was the last the last roll out it had um to the pad was January 8th of 2023 and it didn't launch you know until for 20 uh bo ship 24 wasn't rolled out until uh April 1st and if you look at ship 25 and booster 9 booster 9 was rolled out and put onto the orbital pad on August 22nd and it didn't launch till November 18th um and then you have ship 25 which was rolled out on September 4th and then they proceeded to do what then they proceeded to do seven stacks and D Stacks no eight stacks and D stacks if you count hot staging is the last D stack thanks to Alex um so yeah it's not really there really isn't any good indication of when the launch will be it's an indication that they're getting close that's that's really what it is is they're getting close they're going to probably stack the vehicles they're going to do they're going to do wet dress testing they're going to test the changes to the tank farm you know make sure all the ship stuff works uh they might have a change to the countdown because of all the changes to the tank farm um and you know get the vehicles fully ready and finish off the the Launchpad so the the thing is there just really is no good indication on when it'll actually go but I think the thinking is is like 3 to four weeks or something along those lines is where we're at right now yeah I I could see that it makes sense of you know they wouldn't roll out if they weren't confident that they were close yeah uh along those lines here we got that guy going back to the uh payload dispenser I believe here saying I think uh what it come what it will come down to uh compact most bang for the buck containers that have to be unloaded in Orbiter zg in response to how to build the space station question about space shuttle doors for palads that's what they were saying okay I can kind of see that but again I think the the chomer definitely works best and all I think of is that uh James Bond movie with that oh man which one was that for your eyes only or oh man no it was cuz yeah the the base inside the volcano where they launched the vehicle they went up took a spacecraft and then landed it like like a Starship back inside the the the base which one was that you only lived twice will it surprise you guys if I said I don't know no I I remember it it's aan connory one too I remember it I just couldn't remember the uh the uh yeah well they they say You Only Live Twice or or so they say or so they say anyway uh yes and then the moon raker space shuttles just saying anyway who doesn't love a good space shuttle I mean theirs weren't bad considering that the US space shuttle was still 3 years away from officially flying and all they really had to base it off of was the reveal of Enterprise yeah not bad see even James Bond can get some space stuff right also just Jaws at the end and Trevor has no idea what we're talking about and that somehow makes it better it's not Taylor like how am I supposed to know it if it's not Taylor I mean I could talk Taylor but then then Sawyer wouldn't know so that is true I can't wait for her to win the Super Bowl oh my gosh uh let's see here AAC coming in with another pun let's let's change the subject here with puns I they said my friend Tony Told Me Not to say his name backwards I replied why not oh my gosh it's it's on the screen it makes it even better we can get that off the screen who cleared that off my panel come on that was bad that was really bad I know it was fantastic um let's see here we go some questions in terms of catching uh kale is asking how will they catch the booster uh is it by the lifting points or do we know what the current plan is for that Trevor yeah so as of rain for okay I'm going to preface this with my usual conversation I think catching is a really horrible name for uh what SpaceX is attempting to do so what they're attempting to do is land the booster but just have the landing legs on the top of the vehicle uh and that allows them to have smaller ones that are less massive allowing them to increase Mass to orbit um and that said the current plan seems to be for them to use those pins uh for lifting uh for catching as well however to me that seems just like an extraordinarily small surface to Target so I wouldn't be surprised if uh we see at least at the start um them having uh larger pins or a larger surface of some kind uh that said it definitely seems like SpaceX has not begun working on that too hard um as we haven't even heard any official information about when they are expecting to uh do the uh conduct the first catch attempt there you go another great view here of the Roll coming up close those tight turns oh I I love it that turn there uh someone described it perfectly that guy saying this is like watching the Washington Monument being relocated that's an interesting one yeah uh here's a question from Bruno as well uh Ryan I'll put this one to you saying how come there's no Spotlight on the front of the transporter don't know well well actually I'll put it this way they usually have a spotlight that points on the road in front of everything so that they can see if there's anything on the road that they have to go deal with or or whatever it's so the spnt operator can see the road behind him and the road in front of him so he knows where he's going and everything so they don't point it at the ship they point it in front is what they do and I also imagine that the one on the back uh is convenient for seeing the pressurization lines for any work that they're doing when setting those systems up which probably aren't uh anywhere near as useful on the front of the ship where the heat shield is that' be another gas of mine yeah and that light truck is directly in front of the pressurization vehicle yeah so that would make sense and again you can kind of see the people walking around it as they do that tight turning one of those people is literally out there with a little yellow box steering the thing now comes the Moment of Truth does it go to pad b or does it go to the olm we need a poll in chat to see what people think oh such a great view with booster 10 there it's ride waiting for it it's like come closer come to me I want to launch [Laughter] you you know it's late when looks like a good chunk of people are thinking ol I'm here yeah I mean that's the hope as much as the static fire is awesome it'd be nice to kind of skip it you know this shot right now just has to brings up the Nostalgia in me remember when Star Hoppers seemed huge and we like oh my gosh that thing is so big you know I can't believe that thing's going to fly and now it's just so tiny in the landscape that is current star base even like sn5 and sn5 and six with the the hilarious massim on top I I remember when they went to launch those I I thought those would tip over during flight I'm going to pull Mr Jack bu and bring up tribalism here it's not a mass simulator you can't simulate Mass bo boo I know what you mean though but yeah and um if we're really going to do that then I'm going to call it hoppy and say that we still need to get Jack to wear a kilt nose cone Sim then I don't know what what would you call it Trevor um it's just Mass just Mass but here here's here's my argument for this I I just say this for using the name Mass Sim is that um and it looks like it's rolling towards the olm um the the mass Sim like cuz the nose cone has mass but you don't have a nose cone on it you have that block there to simulate the mass that a nose cone would have yes but it's just Mass oh whatever I mean Kevin in the back panel says payload simulator yeah payload simulator would be fine um be you know that that name actually makes sense but calling it a mass simulator makes it seem like it's somehow simulating Mass but no it just is mass and you know the center of gravity and everything is you know I assume they design it way that it's basically the same anyway so it's just like it's it's Mass okay this is a massive off topic here [Laughter] so you you can't get rid of mass now yeah hey look it's ship it's ship 28 looks like we're going to get a full stack folks as I mean there is uh potential for testing [Music] tomorrow oh no Monday's are Monday yeah tomorrow is a 2hour Clos which I don't know if that was a backup closure or if they're going to use it to stack which is kind of odd CU they don't really need a closure to stack it they've stacked a lot of times without them if we all remember the the multiple times they stacked and D stacked 25 and N for no reason um and then there were people asking as well of the position of the Chopsticks which we can kind of see now they're not are they in the lift position uh no they're not in the lift position but in this kind of case all they really need to do is open the ship will go in and then the Chopsticks will go will open up and around it they don't they don't really have to go up any higher unlike with the booster they can sit down like that with the ship in between there we go uh Philip dery uh asking how will Starship boil off cryogenic methane and locks on a six- Monon Journey to Mars I don't know if they even know the answer to that Trevor any ideas um how will they manage boof uh the good thing about the header tanks is they're pretty darn good vacuums uh or pretty darn darn well insulated um right there's basically just a bunch of vacuum uh well I guess it's not a vacuum a bunch of gas surrounding them and gas is a pretty good um thermal insulator so uh they will be able to um you know spaces very hot but also very cold so using the cold side of it they'll be able to make sure that there's not too much heat going to those tanks um especially when they're pretty well insulated as I was saying uh Jason thank you as well for the support no message but still appreciated A's the Space Cat I don't know where my space cat is at the moment but um saying after seeing emis and Vulcan launches SpaceX utilize solid rocket boosters attached to the booster to save on potential orbital refills and if not why Ryan kbal Kerbal style um SpaceX and I'm pretty sure I don't know if elon's everever talked about it or if he's ever said it but I I don't think SpaceX is really that big of a fan of solid rocket boosters they're not reusable really um unless unless they they were the shuttle ones very can I go into I I I think this is a good time to go into a little bit of an interesting physics conversation about why srbs make sense on a launch system like Vulcan but not as much on a launch system like Starship um so there the two things that we need to keep in mind when going uh when discussing these systems is first of all Delta V which right the um how you calculate Delta V is Delta V is equal to exhaust velocity uh of the uh gas times the natural log of the uh Mass ratio so um uh then Additionally you have this gravity drag piece where um when you are going up uh lifting off right gravity is pulling you down at 9.8 m/s squared times the mass of your vehicle and that's the force it's going down so the first 9.8 m/s squar of acceleration that the engines would give just goes to canceling out gravity um and that's what uh hovering just is so uh after you go to um above uh thrust weight ratio 1.1 is when you actually start getting useful work from the vehicle and that's when the you know Delta V stops going from wasted uh against the gravity well of Earth and actually going to uh your uh orbit so um when you start looking at a system like a Vulcan it makes a lot of sense to have srbs not because the srbs add that much Delta V to the vehicle in fact if you do the math of the amount of Delta the SBS add it's very very little however what they give you is a significantly higher thrust to weight ratio which allows you to more efficiently use the Delta V that the vehicle already has when for Starship this is very very much not the case um R Starship already has a high thrust to weight ratio so they're able to already efficiently use the Delta v um that's in those tanks so adding on srvs wouldn't give them that much sorry for the long explanation but everyone's like really 2:30 in the morning for this like be the physics Trevor says ni everyone perfect response AST knuckle has said and this is the guy that never saw the Matrix okay well here's here's my answer to that SRB is funny on uh Kerbal haha but also that's a lot of things that are going to be needed in orbit for refueling so at that point it's not you're not getting enough of a savings TLD oh God ew not to mention I I was they're cheap easy thrust but uh liquid boosters is better better way better any who yeah hopefully um that rant was at least or not rant that explanation was at least somewhat helpful for uh answering the question and Patrick is asking if this is going to be on the exam if you look at the ticker Trevor will this be on the exam for after the stream uh yes uh also on the exam Patrick will be the difference between your and your just for [Laughter] you oh man oh man oh that's a little uh fun behind the scenes there but yes we love to make fun of spelling oh boy uh which by the way today is the first day I learned that you can like people's super chats in chat new thing apparently with YouTube yeah looks new yeah along those lines that guy saying uh don't stand in the door dude I guess that was earlier in the role uh Lonnie thank you for becoming upgrading to a Capcom member uh see you in the Discord don't forget to pop in and say hi Jason tyin thank you for becoming a pad rat member oh all right arber talk only because you've been so generous tonight I'll I'll say this to Trevor is Taylor Swift good at taking care of plants yeah she's basically covered in Ivy ah I love that song so much I have been obsessed with ever more recently so very good reference uh so yes uh thank you very much for that uh Houston Lucas saying team Trevor's midnight math lessons uh Patrick in the back Channel saying we should make a short out of it the problem is it would be too long for a short okay okay okay just just a question here for chat cuz I'm actually kind of curious about this one so you might be too who would want a video or a live stream of Trevor explaining physics and math who would want that I'm curious I'm going to guess six six all right fa War we wow we've flown past scks already well I was expecting everyone to oh there's one no there we go there's one no I was expecting this to be all NOS apparently people want it well then um Kevin Michael Reed take note for uh future video [Laughter] ideas oh here we go oh yeah everyone better vote Yes that's going to S it I was going to say otherwise it was going to sway it if you had two versions of no so that's better I'm going to silently cast my vote and not say what I put um Mr space repair with an interesting question of uh ship 28 here uh has the Livery been installed yet uh if not could it been installed in the pad or would they return it to the Rocket Garden uh it is not installed yet the SpaceX logo and the s28 logos have not been installed yet um they can easily install it while it's sitting between the chopsticks on his transport stand uh after they do testing with it that is not really anything that's that that requires a roll back um they can do it even while they're doing the FTS install uh it it will only take like an hour or two for them to do that so it it's pretty quick and easy for them to do it it's not really any alarm that they haven't done it yet and uh dunar saying just got back from 40-minute doll walk what I missed missed and and a ship rolling that's what you missed yeah you walk your dog they walk their ship so uh I do not want to have to see the size of the bags though to pick after to pick up after their ship oh my gosh it leaves little tiles as it goes you remember s20 used to do that it tile they would roll it back and they would literally just tiles would just fall off and fly [Music] off oh it actually kind of did you know um apparently it's pretty popular midnight math lessons with wow oh is is the poll still live for you guys 882 82% out of 400 people wow goodness gracious well I guess we're going to have to do this aren't we oh boy someone tell [Laughter] dos if this is going to be done as a short I officially resign oh oh boy now let's uh let's see we apparently pad announcement going on all right Kevin what did it say see if we can uh hear what they had to say although admittedly Trevor would be perfect for brilliant.org yeah thanks Kevin said what of the PA announcement say his response I don't know Sawyer was talking too loud uh let's see Dean Pon saying uh has a booster ship ever fallen over while in transit thankfully no they've done pretty good it sn9 though uh the good old days tipped over in the high Bay um and SpaceX got extraordinarily lucky that day that you know thankfully no one that we know of was uh harmed or anything but that could have been really really bad if I remember correctly I think that was a mess up by fed Jolie I think it's what they're called the company that was doing transports and stuff for Boo for SpaceX for a while I think that was a mess up with the spmt and that's what caused it the tip I don't remember though but that was a while back so at this point as we see the ship is I think it's safe to say that this is not going to the suborbital pad correct uh yeah safe to say so we just need for it to to roll inside the Chopsticks I was going to say the next big deal is going to be a lift at this point which can you believe that we're already that close to a full stack again the stack is back just like mean what at shop. nasaspace life.com we have our brand new patch collection coming soon to bring it up oh coming soon once the full stack is there then maybe we'll be able to debut them hint hint tease teas nudge nudge oops my bad we don't have it yet um leak leak leak I think Adrien just had a heart attack in his sleep right now I'm sorry ad Adrian uh oh I think Adrian oh but uh we do have some uh Last Chance items uh from the second orbital flight test so if you wanted anything from of2 complete your collection going to get everything for all of the flight tests up to this point check it out there's some that are uh getting down to last chance uh stickers as well are also last chance for the first and second excuse me and uh the patches for those first two when they're gone they're gone when that is don't know so you want it now's the chance to get it wow aess plug at 3:30 Eastern 2:30 Central here yeah I'm going to wake up to a DM from Adrian now that's all right I'm probably going to wake up to one from dos from uh earlier comments it's fine uh by the way to the person who asked about out my random ghost guitar string it didn't snap the full string but the string shredded for those who don't know the end of uh NSF live randomly the guitar that behind me um one of the strings just randomly decided to snap or I guess Shear off so I don't know what the heck happened there but it's I don't know the the ghost of uh the ghost of booster nine but never got to see the I don't know uh if that was methane oh that's a great name uh thank you for gifting five red team memberships uh that guy uh thank you for all of the support tonight that guy you've been extremely generous really appreciate it uh saying the greatest problem is the transition from ground to orbit and reverse this consumes a huge amount of energy thus Fuel and always will but we need a better way because of the mass required I may be missing the point this may be a Trevor thing but uh is isn't that what launch and re-entry is the transition from the ground to orbit Trevor m i was muted yeah I think this you know just does a good job highlighting you know how hard of a problem this is right if you look at something like an airliner you know it's a little bit of fuel that's in the wings and then primarily uh you know room for cargo when on a rocket that's entirely opposite you know your mass fraction is only on the order of 8% if you're lucky uh you know it's vastly the vast majority of your mass is fuel um so it's a hard problem and unfortunately physics you know you can cheat many things in life but you can't cheat physics and uh you know there's no way around it it's not too late to cast your votes folks for midnight math lessons with Trevor I mean 700 votes and it's an 80% I mean it it it's especially well fitting since it has a tailor reference in it and math reference like that's like 50% of my personality I think it's more than 50% of your personality knowing you that's more than 50% than that it's like 75% and the other 25 is rock climbing very true yeah for me I I would say it's about 50% yay Rockets uh 40% Bruce Springsteen and 20% math uh it's here it's kind of hard like it's probably 50% Rockets oh no it's really it's really hard it's like rockets rockets and airplanes together kind of thing and then the rest is tayor and other stuff but yeah know as one of my friends always says there that's somewhat related to what so was saying there are one zero types of people in this world those who know binary and those who don't yes thank you to the people in chat that got the joke did did you guys caught it right hopefully well no it was it was 50% Rockets 40% Bruce Springsteen 20% math yeah yeah that's 110% you can have 110% well that was the joke is that I suck at math so that's why the 20% was math and it was over I think I think it's too be funnier when you explain it you know I think it's I think I think it's too late at night for us to catch this kind of thing somewhere I I appreciate the people in chat that did right to the person who said if you have to explain the joke that makes it even funnier just exactly that's how that line ends right I think so okay I see a question in chat by the way asking for an explanation of the rocket equation and I have good news for you that I've actually been working with DOs uh on making this into a video um you know the hard part of this was having it actually be interesting um so that we're not just doing um you know math for 10 minutes straight doing the derivation of the rocket equation but um I I guess the quick uh explanation the quick tldr that I can give you uh for those who are interested is let's say you are on a skateboard uh or on a boat in the middle of the ocean you have a backpack full of bricks and the first thing that you may do is like like throw the entire backpack off the boat at some velocity v um and it's pretty clearly to see that based on conservation momentum uh since you throw the backpack one way it must push you um the other way so then uh immediately from that since uh momentum is just um mass times velocity it's pretty clear to see that the velocity of your exhaust is going to be directly proportional to your Delta V but then additionally uh you have this prop you have this idea that as you throw let say one of those bricks at a time of every brick uh in your backpack it'll be more efficient than throwing the entire backpack off at once and through the uh calculus which need not be gotten into uh you'll see that that's where you get the natural log term um so all the rocket equation is saying is that the Delta V of the vehicle is equal to uh the uh exhaust velocity uh uh times the natural log of the Mass ratio which I believe is the wet mass um over uh sorry the yeah total mass uh with propellant over total mass without propellant why you for the video why are first off why are you carry bricks and second off wet logs too dude you've got a hoarding problem here yeah so yeah there's the there's the tldr um we'll have to do thisr so here that's the tldr i i i my favor was someone who said is it too late to change my vote yeah Al as Alex says in the back Channel that's a long tldr yes uh so the the one final thing I'll say um is the I know a lot of us are used to hearing uh ISP done uh or given in units of seconds we'll say like Raptor has ISP of what 360 whatever seconds and that unit is a little bit weird uh because the way that ISP is calculated is it's actually for Rocket engines where you uh and for Rockets where all of your propellant is stored on board it is directly proportional to your exhaust velocity um so ISP is purely a measure of how quickly each uh molecule is being shot out the back of the rocket first off what did your inter service provider ever du to you to disappoint you that much yeah right um oh yes not specific impulse man to long I I I still haven't processed what you said so that's why I go to pun no it's it's too late at night it's too late at night at this point Trevor it's just too late late for this yeah too late it's interesting but it's too late at night for it first off whoever the person that said I want my ISP to run in a rocket yes um and then uh Mikey saying just remembered I hate [Laughter] math ladies and gentlemen this is why I went to school for journalism for this exact reason because I didn't have to do math but I still get to talk Rockets that's why I'm a mechanic don't really want to deal with math that much I'm happy what planes do you work on the 737 NG okay NG good never mind NGS I don't work on the max the NG fair enough otherwise I was going to say You' got some screws loose for working on that plane exactly in multiple ways we're not going to go there though yes don't want to get me started on that uh Kevin Michael Reed I don't know who this person is super saying here's my tuition payment for today's class thanks Trevor thank you Kevin I for seeing you in my office hours oh yeah you're in trouble now you're going to have to go to office hours um dunard thank you for gifting five rad team memberships apologies to the five people that got gifted in about in regards to math here but hopefully you actually do enjoy the rest of the perks that go along with it with the uh the videos the pictures especially all this stuff from Starbase there are going to be some really cool photos I'm sure coming as we get ready to stack and uh another 20 people just got gifted red team memberships with the thanks of Molly mirams thank you for gifting those 20 red team memberships wow ow holy cow oh no wait that's McGregor but yes if you did get a uh gifted membership from Molly definitely give him a thank you and then uh Drew are also saying stack for hot staging test so uh I think it's a good point to say uh what's next well uh what's next will be is the Chopsticks will open uh the ship will move in between them and uh the the arms will then go up connect to the ship the ship will then get lifted up onto the booster and stacked and at this rate uh there is a closure in the morning from 8:00 a.m. to 10:00 a.m. which could be for the stack but they usually haven't used uh closures in the past and uh but you know with SpaceX it's always hard to tell so but we're probably expecting a stack in the morning uh Trevor's the math person here but I think 50 is a huge number here Matt's gusar I really hope I'm pronouncing that right with 50 5 gifted red team memberships goodness gracious wow uh I I I thank you trying to come up with words at this hour but there are no words it is because of support like this 50 gifted memberships that we're able to bring you all of these views here I mean in fact we're able to get on this late at night deploy cameras that get up close views of the Treads and the engines and all that to have these 24/7 live feeds from three different places with McGregor Starbase and space Co Hast I wow thank you thank you thank you and uh hopefully uh the people that did get the membership maybe some people that might not have been able to get a membership before get a chance to try it out and see what it's like get some of those uh behind the scenes pictures and videos and hopefully the people that got it enjoy it so huge thank you can't be the only one that just words hard and then uh Marte thank you as well for becoming a pad rat member all of our members we love them we really do and uh James cup for asking can Trevor name all six James Bond actors uh I couldn't have even told you there were six so let me see let me see if I remember them so you've got Sean connory you've got George Len be you've got um Roger Moore um Timothy Dalton uh Pierce broen and Daniel Craig yeah got him and I I promise I was not Googling that I have a loud keyboard you would have heard it I promise that was literally off the top of my head do I win anything uh you win up on token ooh you know what I'll actually take that thank you there was seven is there seven who someone said there's something wait who am I missing then I don't know I looked up I I'm talking about like the the the broccoli family ones like the main ones yeah Bing says there were only six and Bing is never wrong so thing is never wrong David nen oh that was oh come on that's a oh that's the original Casino Royale that wasn't an Albert and broccoli one so I don't really think I count that so yeah then again there was also the ones when Sean connory came back for the licensed unlicensed ones so the licensed unlicensed Licensed to Kill yep that's how that works right I think that's how that works anyway um thank you for the pun token I appreciate that on the screen there uh so hopefully we will get to see this thing lift off the ground tomorrow so um we'll hopefully get that going in the Chopsticks what do we have in terms of uh road closures for tomorrow Trevor yeah so there is a nice and short road closure tomorrow from 8: to 10:00 a.m. local uh which you know as always we don't have we don't know for sure what exactly SpaceX is going to be doing during this closure but we can conjecture that it may be for uh stacking purposes and if that is the case make sure you tune in cuz that'll be exciting for more reasons than one as I may have accidentally said too soon and uh yeah the words of a Billy Joel song Tomorrow is today so we're talking tonight it's today today UTC I I will say though this stack been a long time coming so let's H let's let's get it stacked yes yes yes I'm totally on board with that at least Trevor got that one I'm guessing well I mean there's also a Bruce song with that title I'm guessing it was a Taylor song it's not a tailored title it's something she says in a song but yeah anyways the opening of the Aras tour is her popping out and saying it's been a long time coming but and then yeah I I won't sing the rest of the tour yeah that will get us copy right claimed um in the words of Patrick no more Taylor references it's 3:00 a.m. server mute oh gosh he did say he did have a typo in the it's 3: a.m. which is very on brand holding down the shift bar yeah what's even crazier it's yeah it's 10 to 3 Central Time which means we're on the East Coast here it's uh 10 to 4 and no sign language okay no signing for Patrick it was meant to be singing but yeah H anyway um I I I think we're in trouble here that guyy is saying tomorrow will be history soon enough uh speaking of History better than math so no I agree yep and I think all of our new members would agree with that so I do want to give a thank you to all the members that are out there especially the ones who joined us tonight and the generous support from people that allowed so many new members to actually join in tonight so thank you for that and uh I do want to thank the co-hosts that were with me here tonight as well uh thank you very much Ryan Weber ah thanks so it's always fun always love the puns always have a ton of fun here at NSF and uh let's uh let's hope for a full stack tomorrow and thank you kind of as much Trevor sayic yeah no thank you all for dealing with my late night math lectures and Taylor references it's always fun to um get to explain those things so I hope you guys at least didn't find it awful we need your promise folks that if we end up doing this uh math with Trevor segment whatever it ends up being that you'll actually the 80% of you that said you'd watch it will actually watch it so it would be fun like um especially if Alex was on as well I think we could have a good time it would just be you know maybe no man it could it could get boring hi Alex you missed the whole stream not that you were totally muted in the back channel the entire time that we were on but you joined a little late uh and Gage I do want to give Gage a shout out here as well he was helping with some of the uh cameras as well so Gage thank you as always this is the man who's also the Gage is the master of the uh trackpad track so shout out there and uh to of course Patrick hon who's the one pushing the buttons pulling the levers allegedly running a human in a human hamster wheel I it may have just been he might be you know uh and apparently thank you to Gary the grle from people in the back Channel with the Graal fan club showing up there um I'd like to thank myself apparently according to Patrick um yourself that's the list here thank Gage thank Patrick thank yourself so thank me I'm Sawyer Rosenstein I've been your host uh and thank you Sawyer thanks Sawyer hi Bob hi Bob oh um but obviously we still have some things to keep an eye on we'll keep an eye on for the Chopsticks moving we've got that lift coming up hopefully uh in a very short while but you can of course keep an eye on everything that's going on leading up to our next commentary stream over at uh Starbase live which is our 24/7 live feed over there there you can see it we got four different views all watching as we hopefully get ship 28 which is now at the launch site lifted on top booster 10 so we'll send you over there I'm going to send myself to bed and uh send Trevor to go listen to Taylor Swift for two hours have a great night everybody and uh we will see you for Lyft very soon and here we go we have LIF off propulsion continues to be normal r68 chamber pressure looks good probably not Tower [Music] fly go down Toom [Music] off orang 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 Ming it be exiting in the flare [Music] correct we don't need any more of these
