told you so

Gas old space, rocket wars now!

I am just going to say it, Boeing and ULA wouldn't have lost SN8 in a crash. Controversial, but you know it's true.

>>12444257
Scheduled disposal > RUD

>>12444257
You're right, but they would've tentatively launched SN8 in 2025 with 2 more years until SN9 flies.

they legit got all of the data they needed, didn’t they? Only the last .5 seconds of flight were anomalous. And they already know what the problem was.
Like 96% success. Relight, flip, aligning with the pad, coming in with little to no horizontal velocity. Great job SpaceX!

I cooomed so hard during the test, and it'll get even better with future starships

>>12444257
correct, they'd have lost it in shipping

>>12444257
I doubt that Boeing and ULA would even have a SN1 by this time

How does Raptor ignite if it doesn't use Ttab?

>>12444257
Why bother? It's going to get scrapped anyway. Might as well go out with style.

>>12444280
I competely missed it live and when I read about the crash I kept expecting it all to go wrong at every point. Extremely surprised at how successfully it failed desu

>>12444245
They seemed to use that to crab it out for some horizontal flying during the freefall.

Not gonna lie my onions levels peaked when it flipped up from the bellyflop and almost landed.

This went perfectly. I want to suck Elon's cock.

Shame Tom wasn't in the air to record this.

>>12444310
Uh, winnie the pooh?

>>12444257
Yeah, because they wouldn't even launch it.

That last second rotation would probably feel sick as fuck when riding it.

>>12444204
Disappointed she crashed, but not entirely unsurprised. I thought the Raptors would fail but no, low pressure in the header tank.

>>12444332
Yeah, I'd love to see some g-loading data from the flight. I'm curious what the peak g experienced on impact was at the nose. It looked almost survivable, explosion notwithstanding.

I wish I were part of the clean up crew, so I could take a piece of SN8 home with me.

>>12444339
yes. 3 engine raptor flight, shutdown of 3 sequentially, perfect control on ascent. fallover; passive stability, flaps moving perfectly. Aimed guided flight towards landing flight. switchover to header tanks; DOUBLE raptor relight DURING flight; pitchover; roll control; aim remained perfect to landing pad.

it was amazing.

Why aren't they re launching it
I thought they were re usable

Meanwhile in other space news

>>12444339
Yeah, they got lot of things right.

Also agreed >>12444359

So the limiting factor is how quickly they can build raptors, right? And I don't know how you scale that up like 13x for what they need for even one starship.

>>12444339
1000%
Literally everything went right, proving all their methods, except for one small glitch that they already figured out and can fix easily, meaning it's exactly as valuable as a totally successful test would have been except we still got to see some kickass explosions

>So the limiting factor is how quickly they can build raptors, right?
Nope, they're already building Raptors at an insane rate, one of the ones that just got fed to a concrete pad was #42, which means they're probably building something like #60 by now.
The bottleneck is actually the rate at which they can get permission to fly these things, and I'm not joking. If SpaceX were written a permit for indefinite range clearance they would be testing shit much more often, and at that point they'd be limited by Starship production rates more than Raptor production rates.
For example one of the big ticket testing milestones coming up is going to be the first Booster prototype, which is only gonna need two or three engines to do all the testing it needs to do before being able to be used to launch Starship prototypes. This means that as long as SpaceX can get enough inventory for one fully loaded Booster stage they're pretty much golden. Remember that the Booster will be even easier to recover and land than a Falcon 9 first stage, due to having a greater range of throttle control and some other improvements.

Not really, the implication is that the test was a failure when things went really good and milestones that had never been performed by a vehicle were performed

>>12444280
hard to say since one of the raptors gave out, might be that they could've nailed the landing with full thrust, maybe not.

Yeah, they would have delayed the launch for another year, then canceled it due to ((insufficient funding)).

>>12444463
launch 2 rockets, mommy lets you have two

>>12444384
NGL when I first watched the ascent it looked super violent and pretty scary but on re-watching the only violent part was the fast gimbal of the engine to point it out of the way. Look at the ground cam pointed at the vehicle and you can see it hardly even wobbles.
What's interesting is how Starship didn't just burn full throttle and then coast to apoapsis, it pretty much burned at a lower and lower throttle until it reached apoapsis and was almost just hovering there. My guess is that they wanted to eliminate the complexity of having it assume its aerodynamically stable position while still ascending, then do a sort of lazy flip passing through apoapsis before coming back down.

Controlled demolition! SN 8 was an inside job! Its destruction was just a cover up to mask the destruction of the nearby sprung tent. Don't you think it's odd that the tent only caught fire way after SN8 exploded?

>>12444408
Probably the chamber throat, since it's usually the point of maximum thermal flux in any rocket engine. Also, if it were the preburners the engine would not have continued firing, it would have instantly shat its guts out

They need to pressure test it. Who knows how much they need to fix after the touchdown.

Somewhere in January/February. They have to analyze SN8 data, apply changes to SN9 wherever they can be applied to, install the rocket onto the pad, pressure test, static fire test and then finaly the high altitude flight test.

There's also Christmass and New Years when work is halted for the holidays.

Yeah totally. Any other rocket company that doesn't want to be rendered utterly irrelevant (whilst remembering the heat shield is still unproven) would redirect its entire effort to reusability and a rapid iteration approach first thing tomorrow morning. The writing was already on the wall with Falcon 9 but now surely, surely the idiotic inertia of oldspace must start to change? If they wait until full stack Starship is flying surely it's over at least for competing for commercial launches?

I recall that raptor burns green when it is fuel rich and eats away the engine bell. The flop makes starship have a larger cross-sectional area to its velocity vector, meaning more energy is scrubbed away by atmospheric pressure differential (not friction as most people think)

if it were to just slam into the ground without turning back over and burning, it would only be going like 50 m/s. Survivable with a crash cage

>>12444596
It looked really fucking flow before it did the flip. I’m not sure how fast it was going, but it definitely wasn’t in free fall.

I don't wanna like gatekeep emotions or anything but this stuff is just kind of the nature of the business in both industry and research, wait till you get a payload on a launch vehicle or are a part of a longer term mission.

Raptor spitting green flames for 3 whole seconds before the rocket just plopped down and slowly burst was a really kino failure. Not quite an SRB inflight failure kino, but still pretty far up there. More engines need to spit weird colors before they die.

I can confirm that even the ones that get hired as SDEs at west coast FAGMAN companies are total pinheads.

So with this test, they've essentially proven most of the risky part of Starship. Landing will be had in the next one for sure. Now all they need to do is prove out the heatshield, orbital refueling and superheavy.

I just realized that SpaceX demonstrated the reliability of Raptor big time here.

1) 3 Raptors firing for a minute and a half together
2) Ability to shut down a Raptor mid flight.
3) 2 Raptors burning for THREE MINUTES!
4) 1 Raptor burns for 4 minutes straight.

>>12444845
Yes, successful ascent, successful flip, fuel header tank pressure issue, green flame on relight and crater – but the crater was on the landing pad!

>>12444845
yee, feel bad for you

>>12444845
Flew great, flopped great, RUD'ed great as it almost stuck the landing when it ran out of oxidizer on the landing and started running engine rich. 10/10 all in all.
Shit was awesome.

>>12444841
>orbital refueling
This is a potential hurdle why exactly?

>>12444530
How the fuck is it falling so slowly? Anyone know approximate speed? Looked like a fat feather.

>>12444305
0/10 wrong angle

So the Raptor shutoffs during ascent were expected?

>>12444852
Not just during the ascent, but both Raptor that attempted to restart during the flip did so perfectly, and if it weren't for the header tanks losing pressure we would have had a successful touch down. Literally spotless reliability for Raptor, only issue of minor concern is a bit of gimbal jank during ascent.

>>12444862

It'll probably be fine but it might take a couple iterations to work consistently

SpaceX planned for explosions so each setback is about three weeks

>>12444862
No real exact hurdle except that no one has really done it yet on the scale of Starship.

>>12444830
no, it's not. They did impact tests for curiosity's RTG for example and a launch failure wouldn't threaten the integrity of it at all

>>12444868
Yes, to slow it down and move it over the water

>>12444870
Why not just push it with a big pusher?

>>12444841
Yeah I thought it was going to lose control and do a few loop-de-loops on the first flop attempt, but it did that part flawlessly.
The flop-turn maneuver doesn't look nearly as zany in real life as it did in simulations and my imagination. Shockingly graceful.

>We are targeting March 29, 2021 for our next #Starliner flight, Orbital Flight Test-2.
https://twitter.com/BoeingSpace/status/1336814329275035648

>>12444868
yes. throttling speed to limit aerodynamic stress. if you look at the shutdowns, the engines gimbal to far-out position. Also, all 3 engines shut down; 2 relit for the landing burn (as expected)

>>12444863
>How the fuck is it falling so slowly?
It's extremely huge, it' high up so points of reference are difficult to piece together, and it actually is falling pretty slowly, due to being a thin steel tube that's mostly empty and falling sideways with big drag flaps deployed.
>approximate speed
9 meters wide and maybe four or five body widths per second, so aroudn 50 m/s, exactly inside their predicted velocity.

>>12444874
Let's hope those iterations won't be quite as explody up in orbit.

i miss her already bros...

>>12444868
Yeah, they shutdown one by one until they reached their desired/controlled altitude of 12.5km. They could've shutdown all 3 slightly earlier, but its probably more efficient to do it slowly.

>>12444846
They are both immortal in our hearts and minds though.

>>12444436
>>12444419
absolute trash. At least BBC's article is more decent https://www.bbc.com/news/science-environment-55239628

>>12444870
Well, people will tell you it's hard. Elon hasn't said he's concerned about it so presumably he's either ignorant of some major issue or he's just not scared of the stuff just because it's cryogenic. In principal their plan of using ullage thrust to settle the propellants and then differential gas pressure to force the liquid across is perfectly sound.

>>12444868
you don't want to suddenly cut off all thrust and send sn8 tumbling upwards, so they did it gradually instead.

>>12444895
We haven't ever tested moving lots of fuel between big tanks though (they could have if they didn't dispose of the orange tanks though LMAO)

It becomes slightly surreal/unnerving to the mind when you also remember that it's the size of a 15 story building.

So how many SN prototypes are they up to now?

They nearly nailed it today, I'm thinking that the engineers are fucking pumped tonight and already thinking about how they can fix the landing.

>>12444930
I don't wanna give him views, TL:DR?

>>12444879
Yeah but solid blocks of plutonium oxide inside of an RTG is not the same mechanically as a nuclear thermal rocket's fuel elements, which by design need to be very thin in order to avoid the temperature in the centerline of the fuel becoming too high at high power levels. The thickness of the fuel is fundamentally limited by the specific power of the fuel and the thermal conductivity. If the fuel is operating at a certain power level and is above a certain area density, even perfect cooling fluid flow around the fuel won't be enough to prevent overheating inside the fuel. Since NTR cores need to operate at huge specific power, that means they need very thin fuel elements, with voids in between for propellant/coolant flow, and of course this entire thing needs to be open on one end to allow the propellant to escape out a nozzle.
I'm not saying it's impossible to fix those issues, but it's definitely not the same as an RTG fuel element slug.

Does an engine nozzle get dented right here? https://www.youtube.com/watch?v=ap-BkkrRg-o&t=6680

>>12444911
>We haven't ever tested moving lots of fuel between big tanks though
I mean, SpaceX has been getting plenty of experience doing that already, albeit in 1g on Earth. Really though, if the tanks are in space and under ullage acceleration, what's the difference? Just pressurize one tank and vent the other and blow the liquids across lol. Simple as.
The reason NASA et al are afraid of propellant transfer on orbit is because they never considered just using ullage thrust and avoiding the zero G problems.

>>12444951
more like execution by rocket engine.

>>12444949
Very cool. So the crash was a nothing burger.

>>12444966
