This is a good idea. There will be one thumb for the whole video but in their analytics they can see additional thumbs up and at what point in the video. This is a great missed opportunity for analytics. The additional thumbs could be a different icon, could be called something else. It's too bad they don't data mine the comments for great ideas. I suppose they can monetize it later if they get to it... if they're allowed. Is there an agreement somewhere that says they own all the comments? insert lol somewhere.

[@mannygee005]

I was on the starliner chat and it was amazing. Not only were the comments super funny, what was amazing was that it was not censored - people were calling for moderators on the chat but like Scott said, being open and showing it all live showed very high confidence not only in the technology but in the process of being transparent. Let's say there was a lot of spirited debate in chat... lol. But the "new kids" were in a great mood after starship test flight. The "old kids" let's face it will never accept anything new so... that's how it has to be. We should not expect any seeing eye to eye. Agree that there will always be disagreement. What was amazing was that chat was not shut down. I think they got a lot of views! The hours of delay just added more views, so that was a win.

Just waiting for Starship launches to be as routine as the falcon 9s are.

[@rRekko]

Same. The payload version (the one currently being tested and developed) is relatively close, say they learnt a lot, and i mean a lot from the falcon project, they're showing it already with how quickly and effective they've been at fixing stuff. Not to mention they already knew the flaps hinges were faulty, hence why they put the camera right there in a prime position and angle to capture what happens to them, there really is no other reason why they focused so much on it being how much "boring" it looked compared to what we could've watched from the other camera.

I haven't realize that the ring ejected have a mass of almost 10 little cars... And this is huge! People still have no idea on the scale of the stuff we are talking about... By the way, thanks for all you guys for spending time explaining us how fantastic is the time we are living in, regarding space exploration! :-"

[@revmsj]

Yeah, buddy! This is a huge beast! Remember what IFT-1 did to stage zero! Of course Ship only blasts it with a total of 6 engines, and three of them don’t ignite until it’s a few feet away, but still! It’s a steel ring almost 30ft in diameter, over 6ft tall, it has to hold up something like 1,400 metric tons of Ship and future payload plus the weight of Max Q pushing down on it, and finally has to absorb the kick in the balls of 6 Raptor engines @ up to about 1,380 tons of cutting touch-like exhaust! Not to mention their plans of increasing all of these figures by stretching tanks etc. and adding another 3 engines and Raptor 3’s proposed increase in thrust… TBH, in my mind this will be their long term theoretical point of failure. As in like an integrated hot staging ring on Super Heavy Booster will be the deciding factor on just how many launches they get per booster before having to either strip it off and replace it, or retire the booster all together. I wouldn’t be at all surprised if initial tests show a 2nd flight with integrated ring isn’t feasible as they will necessarily have to substantially bring down the weight to provide a proper center of mass and ballistic coefficient and not lose control @ boost back, reentry, etc. I also wouldn’t be surprised if 1st hot staging w/ a 6 engine variant cuts right through the shield on the ring and blows up Super Heavy which would then kill Ship… That said, I really hope I’m wrong, and I have tons of faith that they will figure out what needs to be done then do it! History dictates that this is exceedingly probably and I am so got-damned here for it all! 💪🏾😃👍🏾

[@SebSN-y3f]

Well said. He knews what looking for and why. It's just great!

[@THX..1138]

IMO all the extra task they loaded into IFT 3 were really because they didn't think either vehicle would make it to a soft landing anyhow. So they wanted to add things that could be successful into a mission that was likely to end in a double RUD....Different story with IFT 4. Now they had enough confidence it would be successful that then they didn't want to add extra test cuz failure of one of those addon task could cause a RUD.

[@737smartin]

Sounds like nonsense to me. 🤷‍♂️

[@michaelstoliker971]

Can we focus on the fact that they were confidant enough in the control of this rocket to place a buoy with a camera in the ocean where they planned to land so that they could video the landing! That's amazing!

[@THX..1138]

@@737smartin Well on IFT 3 had the door not closed it would have caused a RUD. Had the propellant transfer only partially completed it would have caused a RUD. Neither of these test had anything to do with IFT 3's primary mission which was demonstrating Starship can make orbit and a controlled reentry with a soft water landing of both vehicles. It would have been stupid to risk LOV and failure of your primary mission to conduct either the door or fuel transfer test. If however you're confident the vehicle will RUD at reentry regardless then there is technical, economic and public relations value in conducting the secondary test. As in they collected valuable data without risking a vehicle. They turned public perception of IFT 3 which failed most of it's primary mission goals into a perceived success. And they fulfilled their NASA contract to demonstrate propellant transfer earning SpaceX $250 million dollars...Roughly the price of the vehicle expended in IFT 3.

[@737smartin]

@@THX..1138 You go too far when you make it sound like they were sabotaging flight three, though. There was certainly more risk with running ancillary testing, but I really don’t think they were going nearly that far. We can most certainly agree they decided that flight four was time for a no-nonsense, sure check of the Ship reentry, so ALL focus was there.

[@rRekko]

@@737smartin there is a reason why they put a camera pointing right at a forward flap covering the entire view and focused so much on it. They knew the flap hinges were a weak point, they were expecting starship to RUD, hence why they didn't prepare any cameras or recovery. They thought the booster would reach the water but break so they only put a camera to check how it would eventually RUD or fail. All of these little details people casually skip for some reason. And Fraser here being skeptic because they took a long time with Falcon, assuming none of the tons of knowledge gained wouldn't translate and be the reason starship is moving so quickly compared to falcon. Should be skeptical about other stuff proposed by spacex instead.

[@animistchannel]

Thank you for another episode of The Aftermath Trio! You three have gotten quite good at tossing the issues around in an entertaining and efficient way. It's not just good information, it's fun to watch. You really hit an important outcome of this test flight. As of now, they now DO have the heavy lift system to put big stuff up in one go reliably, and that gives them chances to do that even while they work on fine-tuning other systems to improve re-usability. Starship could put up a telescope with twice the collecting area of JWST without even playing around with unfolding mechanisms, or put up whole probe ships with their own propulsion systems that would "launch" from the Starship itself when already outside of earth's interferences -- and that could be a HUGE boost of effective payload to outer solar system missions.

28:35 If the thing that visibly shatters here had been the camera lens, we would not have continued to see anything even somewhat in focus, let alone the well-defined sparks visible through the gaps. We don't know for certain what cracked (perhaps a protective casing around the entire camera) but it was not the lens.

[@thedausthed]

Lenses generally still work with the front glass broken, but I highly doubt there was not some protective cover glass over the lens.

[@Ellingmint]

It was probably the buildup of metallic spatter from the steel being liquified and vaporized by reentry. That coating built up and broke away several times between the flap becoming compromised and splashdown. It noticeably fell away at the very end when splashdown occurred, and what remained of the flap almost fell off just a second or two before the videofeed was lost.

[@Asterra2]

@@Ellingmint That's what I've seen others speculate and it does make the most sense. Also the flap did actually fall off from the belly impact and tumble behind the hull. A movie writer couldn't come up with something more cliched.

[@The_Real_Corbin_Dallas]

@@Asterra2 the Little Flap That Could.

[@revmsj]

Most likely a redundant protective lens layer or casing as you say, sure. However it’s a hell of a lot simpler to refer to it as a lens in casual conversation than to say “redundant lens protection layer” or “protective casing around entire camera” every single time you wish to refer to it. Your argument here is pedantic and petty…🙄

[@peterwmdavis]

Best analysis yet. Thanks for bringing these two onto your show.

[@petecomps7260]

If you think orbital re-entry is challenging, imagine how much harder it would have been for Dear Moon to re-enter upon return from the moon. Re-entry from orbit is about 7.8 km/s, whereas lunar re-entry is about 11 km/s. Kinetic energy increase by the square of the velocity, so that extra 3.2 km/s translates into roughly doubles the kinetic energy that must be converted to heat during re-entry.

[@revmsj]

I’ve been telling an “Anti-Elon” friend of mine for a while now that for NASA’s lunar landing mission and several other use cases, they truly don’t need to prove reusability or many of the other firsts that they’re ultimately going for. With as inexpensively and as quickly as they’re able to crank out these rockets and engines, they would still continue to destroy the market even further!🤷🏾‍♂️ It’s crazy how someone’s political ideology can not only manifest into hatred for someone they’ve never met, but to also begin to irrationally attack an entire company that person works for but whatever…

[@debott4538]

@@mutleyeng What do you mean? I think SpaceX would be wise to develop an expendable upper stage for Starship, assuming that upper stage resue will take a lot longer until it's available.

[@kerigpope]

Do we know just how much it would cost to keep destroying 30 Raptor engines? 🤔 It might be economical to keep destoying boosters had it only had 3 or 4 engines, but I doubt SpaceX will make much heavy lifting profit if 30 engines are lost each launch.

Isn't their plan to build one starship per day? They can do expendable by charging the costs. Affordability is part of the plan.

Glad you enjoyed it.

[@nerufer]

@Fraser regarding the "secret payload". Let me shut down that rumour right away; the payloadbay door was bolted shut prior to stacking for launch. So there was no payload. Lastly, about the flaps; if you look closely, the heatshield round the belly of the ship performed very good. Spacex plans to move the fins further up and to 1 side so that the plasma will primarily hit the belly part. I have high hopes for this.

[@erb34]

I love these gatherings. I think SpaceX nailed it as a test. Getting close to failure and all the telemetry through starlink is Christmas for the development of the platform. They even left off some tiles to see what would happen. A giant lab experiment!

[@shuriken4852]

One thing that is a positive for SpaceX for sure, is if I ran an airline or cruiseline, after seeing Starlink be able to keep signal in those horrible conditions, if I was not already convinced of the reliability of Starlink, now I am for sure.

[@comediehero]

I feel like sometimes people forget just how fast this program is moving. BFR was announced in 2017. Six years later and we are seeing full scale test flights of the largest rocket ever built. I feel like this is a pace not seen since Appollo. Yes the HLS is not going to be on time for artemis 2024 or even 2026 but thats kinda NASA's own fault for not contracting out the HLS sooner.

At what point does the tower get taller for the next version? At what point the the second stage quick disconnect move to a higher point on the tower?

Yay, its our quarterly tradition of Scott Manley correcting Marcus on various things. But seriously great review again, all star team!

[@tavpierce1880]

I am confused by the lack of payload. Fuel capacity and excess thrust indicate a need for a ballast load of around 150 tons.

Maybe a positive flow coolant system into the hinges.

[@CockatooDude]

Mass and cost is very important. They had been considering coolant systems before but decided against them for those reasons. Likely a slight shuffling around of the tiles or slightly thicker ones in a few places should fix the issue.

[@kindnuguz]

100% Agree with Scott on China's launches. While yes we need to keep paying attention, the transparency isn't there. Nothing goes 100% smooth and how open SpaceX has been shows confidence

[@AnonymousFreakYT]

22:00 - Yeah, "maximum heating" may be achieved early, but it's also not like it's a sudden cutoff after that point. It sustains *VERY HIGH* heating loads for quite a while after. I was just surprised at just how little speed was being bled away at the same time there was ultra-high heating. I mean, I took orbital dynamics in college, so I fully understand the theory, and have seen plenty of simulations; but just seeing it in real time was wild.

[@revmsj]

Yup and after max hearing has thoroughly weakened the structure, you then have denser and denser atmosphere ripping away the softened and weakened materials as you approach reentry Max-Q…

[@Martinit0]

I think Scott is a bit imprecise here with his wording. You have to distinguish "peak temperature" of the plasma (expressed as temperature) vs. "peak heating" as in peak deposition of heat (expressed in Watts, i.e. energy per time). He explains a bit using the example of the oven, where high temperature does not necessarily mean high heating (deposition of heat into an object) since heat transfer depends critically on heat conductivity and whether both objects and in physical contact with each other or not.

[@johanponken]

@@Martinit0 At 22:00 he says first heating, then 'corrects' to temp. Therefore I wonder: do the space techies state "peak heating" like they state "max Q"? And do they do that for what is actually peak temp?

[@ArchieLundy]

Thanks for the breakdown guys. The booster is the real cost to orbit breakthrough in the making. Once it's working you can stick any kind of payload or vehicle on top.

[@elliotsmith9812]

If all else fails, the booster is a major money maker going forward.

[@richardhamilton-gibbs6360]

Thanks for this. Excellent review of Flight $. We're watching history being made in a much more certain and constructive manner than the Apollo methodology in the 1960's (which I lived through as a teenager), and the best part is that it's the beginning of humanity becoming a space-faring species. This is a very exciting beginning.

[@MohammadArifRahim]

At 37:32, I agree with Scott, SpaceX trying to catch the booster. Even I would argue that they should have a dedicated tower to catch the booster with flame diverter and mobile platform to ensure safety of the stage 0.

[@RasakBlood]

The tower might take time to fix. But its the tankfarm that would take the longest. So a tower without a tank farm to practice landings would be the plan in my eyes.

[@MohammadArifRahim]

@@RasakBlood Agreed. More like a dumb tower (without the gas lines) with functional chopsticks and flame diverter.

[@Don_Kikkon]

Wonderful talk, great to see such genuine enthusiasm on the choobs. IFT-4 really did seem to me to be the perfect balance of success and failure. So much learned but still so much to be impressed with. Nice one Spacex!

[@nickamodio721]

There is nothing "reusable" about this thing. This moon mission is so far behind schedule it's embarrassing, and I genuinely feel bad for whoever is going to ride on this deathtrap. They haven't even test launched with a payload yet... and the expected payload keeps getting lowered - it used to be 100 tons... lol Why are people getting so excited about such little progress?!? I'm not just trying to be negative here. This is simply not as impressive as people are saying it is. Nasa did far better with far less during the Apollo missions.

[@fernandosotodecker9182]

Obviously you have no idea at all about spaceflight history, the Apollo program (and how much money it burned) and the amazing achievements we're witnessing right now....and THAT is really embarassing!

[@Spherical_Cow]

During Apollo, NASA was spending more money in a month, than the total of what SpaceX has spent so far on the entire Starship program from its inception until now. "Better with far less"... 🤣 And yeah, why would anyone get excited about the largest - by far - launch system ever built, having just completed a successful test launch just over a year after its orbital test campaign kicked off, and a mere 6 years or so into its development program? Yeah, lots of space programs do that, all the time; /yawn/... 🙄

It looks like super-heavy is really quite close to re-usable (save the hot-stage ring). Which really shouldn't be surprising, since it's roughly an upscale of Falcon-9. Ship is the new challenge. And the heat shield is the really challenging bit.
