Someone post that pic of Michoud celebrating the first bolt of SLS

>>12582882
Aaahah I was just about to post this image. I wanted to talk about how like maybe 10 or 15 years ago it would have been such a cool picture. But now it just elicits no emotion from me. I look at these SRB's and feel nothing but hatred for contractors and cost plus bloat

>SN9 launch and SLS 8 minute static fire both happening this weekend
>one of them's probably going to blow up

>>12582882
Alright guys it’s RealisticWarshipAnon here. I’ve been thinking. If a Nuclear Salt Water engine can fly a brachiostome trajectory with a lot of thrust....why even bother with a fusion engine?

Dubs and SN9 explodes on ignition

>>12582900
I blame you, Anon.

>>12582900
Dubs and it lands on Tim Dodd’s house

>Boing never works on a NASA program again

>>12582918
Either way it'll be a heck of a fireworks show.

>>12582900
I will find you motherfucker.

Dubs and SN10 goes kaboom too

>>12582923

>>12582918
>Boing never works on a NASA program again
Pure fantasy. You and I both know that a Senate-lead commission would find no fault on Boing!

SN9 wont be flying until about Q2 2021, only because it fucked the raptor on shutdown and they have to redo the test campaign

>>12582939
No dubs so not true

Enter the immunity dog

Do we know what kind of hydrocarbons are on Titan?

>>12582951

Yes

>>12582943
When they replace an engine you will apologize

>>12582956
I apologize to no man

>>12582957
That is no man.

>>12582939
This isnt SLS where a minor fuckup results in a 1 year delay.

>>12582956
This is not Boing. They don't need half of year to replace an engine.

>>12582964
You will NEVER be a woman

Come on, the sight of those big-data boosters rolling out on the ML doesn't get your blood pumping even a little bit? You can still think the SLS is a waste of money and nonetheless appreciate a bigass rocket rolling out.

>Next planned rocket launch: Electron on Jan 16
>Next planned Falcon 9 launch: Starlink on Jan 17
>Also planned on Jan 17: Virgin Orbit with LauncherOne
>SLS status: overbudget and behind schedule

>>12582993

I wonder how fast they'd accelerate. Would probably shoot off like an ICBM.

trips and SLS explodes instead

Is the landing flip maneuver actually attainable? It's never been done before, and the maths behind are borderline insane. I think Musk, for one, might be over his head here

>>12582994
Knowing the time and money that have already been blown on it kinda takes the wind out of my sails in terms of being excited. It's like getting a birthday present after catching your mom giving head to afford it. Sure you got a new gameboy but at what cost?

>>12583002
>"Rudimentary creatures of blood and flesh. You touch my mind, fumbling in ignorance, incapable of understanding."

Dubs and Musk cancels the starship program tomorrow

>>12583004

Anon... SN8 nailed the entire maneuver, it worked nearly flawlessly. If the engines have gotten their fuel, it would have landed.

>>12583014
That big explosion at the end says otherwise

>Today’s @BlueOrigin landing and the epic view from above the Kármán line. #NeverGetsOld #GradatimFerociter

>>12583017
It's true. I've been saying it since day 1. SpaceX is a fraud bankrupt joke. Simply the only thing keeping it up is simple hype, plain and simple.

>>12583017
>If the engines have gotten their fuel, it would have landed

>>12583020
What the fuck is it doing for a second there? It's just letting itself hover away from the pad, meaning it has to correct more aggressively just to get back.

>>12582918
>Boing never works on a NASA program again
never going to happen. boing at this point is a nationalized business. its only private by name. government uses it as a slush fund for themselves and can get away using it as a guise of a private company to sell shit overseas for influence and not being weapons. large part of the world depends on boing aircraft and because of that, america.

>>12583020
Someone said in the last thread, but you would think that after so many flights they would actually innovate towards an actual hoverslam.

uhhhhh

what happens if there's a lot of rain or a hurricane?

>>12583004

I'm slightly surprised he was even on site for the launch

>>12583023

>>12583045
well when you start making about $1k a month you can start affording stuff called soap.

>>12583017

You are either a moron or baiting but I'll bite regardless:

1: The skydiving Starship fell in a controlled, stable manner. This worked flawlessly.

2: The wing flaps in combination with RCS thrusters kept the Starship under controll and contributed with the flip. This worked flawlessly.

2a: The engines relit successfully and contributed to flipping the Starship. This worked flawlessly.

3: When there was enough fuel available for the Raptor engines, the Starship was deaccelerating in a similar fashion of a Falcon 9 booster. This worked flawlessly.

The only part that didnt work was fuel pressure in the header tanks and since they know the issue, they can fix it.

>>12583020
this is not good practice if new glenn is to hoverslam jeff's mom

>>12583023
That's right, we should all go to our state representatives, if they're democrat that is, and demand for them to push for the cancelation of the whole starship program
Musk is not the right person at the wheel when it comes to these sorts of things, he knows cars and paypal and thats about it
All of spaceX's scheduling thats made public is completely unrealistic, yet he will not face due consequences for setting such an unrealistic timeline for his ambitions, no matter how deluded they may sound

>>12583045
He actually had some dirt on him in another picture in the set. Even then, it's like he showed up for photo ops and left.

>>12583035
The place really should have been raised before construction but Elon is from C*lifornia and doesn't believe in weather. The monetary losses wouldn't be significant and most stuff could be carted out but the big loss would be time

>>12583059
Listen here you big virgin, this starship thingy is going nowhere
Mars is already taken, and it belongs to oldspace
The jobs NASA creates keep it afloat, and barely at that
We can cut funding and end all of your precious fantasies if we don't like how things are looking over at the agency, and we sure as hell can pull some strings to ensure spaceX takes the same route

>>12583078
No, all boaters. Indiscriminately.

you're mentally ill. you can keep denying reality like trump denying he lost but it won't change reality. like trump isn't your president anymore, starship is going somewhere. if you against one man spending money and the government funding projects to advance humanity then quite frankly you are the scum of the earth that needs to go back gagging on trumps orange cock.

Not anon but that type of talk is really disgusting and dangerous. Evolution gave us the greatest gift, the ability to protect ourselves. Capable of having the opportunity to not go extinct on this planet like all species before us. Along with the added ability to save the other creatures evolution made by bring them with us.
A cat will never fly. Will never ride a rocket into space. A cat without us will go extinct on planet. We don't have to. We can save ourselves while also spreading life on this planet to other planets.

We need to honour evolutions gift to spread not only our species amongst the stars but the other species on this planet. We owe it to them for everything we have done and the sacrifices they have made to benefit us. We cannot slow down or stop our advancement. We cannot let the greatest gift evolution has ever given to a species go to waste because a bunch of idiots who only care about themselves in the now for short term benefits.

We are the dominate species on this planet because of our technology. We are not an organic species. The moment we picked up a spear to hunt to artificially increase our range and deadlyness we became artificial. We cannot forgo that. We cannot stop. We have to get off this rock and do everything we must. Or our evolution was a waste and pointless.

Historical records show only 1 small overflow of water that destroyed the original boca chica village. I've wondered about it myself, but I think they've got most of their hardware above a certain water level that they can ignore it.

Why do you think Elon is going to fucking Mars of all places? It’s the one place in the solar system you can build a future on with a bunch of long nosed gentleman showing up to destroy you with their golem.

Hopefully spacex accelerates even faster in their operations as things back home are becoming increasingly unstable. Once he gets that colony and it becomes sustainable then all will be well.

>>12583176

>>12583020
I'm kinda mixed. One one hand it was literally going to miss the pad. Had momentum in the wrong direction and it failed to compensate for that. The only reason it didn't miss it entirely was because it pulled that severe tilt maneuver. On the other hand it's kinda impressive that it managed to do correct course so hard without eating shit

>>12583027
the way its landing algorithm is written?
when altitude =< x && v = 0
{ appraise location, make corrections, bring altitude down to 0}

You can see it have an "oh shit" moment when v = 0 and it clearly moves into a new decision-making tree. It apparently failed to "see" the fact that it was drifting.

I guess once the adrenaline wore off and you came to terms with it, it could be pretty relaxing. Just shooting the shit with Mission Control and whatever family members they can get on the radio before calmly passing away and eventually becoming one hell of a shooting star.

>>12583225
SLS is real. You've seen it down at Michoud. We're building the core stage. We have all the engines done, ready to be put on the test stand at Stennis... I don't see any hardware for a Falcon 9 Heavy, except that he's going to take three Falcon 9s and put them together and that becomes the Heavy. It's not that easy in rocketry."

You ever have a moment where something happens and in an instant you know it's fucked and will require a lot more effort to repair/clean? I imagine it'd be like that, maybe with a few desperate minutes of hoping someone else finds a solution to your predicament.
That part would suck balls, absolutely. Resigning oneself to fate after, not so much, depending on the person I guess.

>Martians actually become the most prolific shitposters because they spend 14 minutes posting into the aether before checking for (You)s

>>12583252
Probably want to do extra checks. I think SpaceX really doesn’t want SN9 to crater, too, after getting so close the first time. If SN8 failed on ascent or something SpaceX could just say “Oh well we tried and now we have data :)” but now that SN8 went so well the bar is a bit higher.

I like how the webm you posted is the complete opposite of the clusterfuck you call your political ideology. Starship is based, but so was raiding the capitol. It wasn't even for the orange man anymore, it was because the legislative branch was being too jewish.

>>12583193
>On the other hand it's kinda impressive that it managed to do correct course so hard without eating shit
You're not wrong, but the massive issue with the landing system is that it has no smooth transition. It comes screaming in, goes to a hover, then settles down. BO has huge issues with controlling the flight path down to the pad, so they rely heavily on NS being able to get close, come to a hover, then land. You got to see today what happens when the falling pattern is really messed up, it has to regain control and drift back to the pad.
Don't get me wrong, it is impressive and it works. But if BO thinks they can do the same thing with New Glenn, they are going lose a lot of boosters.

>>12583401
>But if BO thinks they can do the same thing with New Glenn, they are going lose a lot of boosters.
Good. Maybe they'll learn from their mistakes faster than from endlessly studying models

>>12583383
Neither of them killed anyone personally as far as I know, but Stalin might have beaten people a few times, and ran gangs, so probably Stalin.

>>12583383
Arguably Stalin as he is known to have personally killed people. He had hundreds of thousands of his own party members and even some of his friends purged and he fucked up any internal faction or ethnic group that tried any shit like the kulaks or didn’t try anything in the case of the Volga Germans and he would have soldiers or officers killed just for fucking up.

Hitler could match him when it came to brutality at war, but for internal actions Stalin has this one in the bag.

>>12583401
The ship is going to be moving (literally, under power) when New Glenn comes in to land so it literally cannot have any time to hover, it would be hovering right into the manned control deck if it did. So yeah, they absolutely need to fix everything about the landing and NS should have been the test bed for it but they don't care.
It used to seem like a sure thing BO would at least produce the first reusable orbital class booster not under the auspices of SpaceX. As this goes on I start to wonder.

Hovering static relative to the ground is functionally identical to hovering static relative to a moving target in terms of software desu.

>>12583429
No. Next old concept?

>>12583435
How about this one?

>>12583432
So they're gonna pull up alongside, match speed, and tokyo drifto into place? Because that does not at all sound as easy as hovering and putting down without matching lateral velocity with a third party, and just saying it doesn't make it convincing. It'd be pretty sick though, admittedly.

neither and both. everyone will treat earth as 'home' and most will retire there someday. majority of people will never leave the planet and obviously the poor are stuck here, but the rich won't be escaping either (because not earth is going to be shittier than earth for a LONG time)

>>12583443
Hovering relative to the ground is just adjusting to get zero velocity vectors relative to the ground. Its the same for a moving target except for the vertical axis, which for a boat will be variable. If you want to make it sound really complicated just mention that New Shephard is actually cancelling velocity relative to the surface of a massive spinning ball of magma with a thin rock crust hurtling around the Sun at 30km/s.

Well in that case yeah, probably a 0-0 kd ratio on that guy.

>>12582990
they pretty much did already

>>12583491
You can't make matching speed with the ship not an extra step. Well, actually, you could. If you did a proper suicide burn. To do it while hovering, though, means managing an additional velocity during that maneuver. Go re-watch their booster's behavior with absolutely no significant confounding factors and see if you think that same booster is ready to manage even a small tangential velocity vector while handling the same maneuver.

>>12583462
The drop engine half-stage had parachutes. It's the original version of what became SMART. You're "only" throwing away a single engine plus the stage body. With F-1Bs it'd actually be a pretty cheap design.

Ares I was awesome but horribly impractical. It would’ve flown Orion for the first time in 2015...three years after Dragon flew on Falcon 9 for 1/3rd the cost

>>12583536
... on a solid booster that almost guarantees death in the event of a failure

>>12583545
Well I mean they are sending astronauts on starliner which almost guarantees death even without the event of a failure.

>>12582898
SN9 is going to explode for sure, I think the 4th or 5th attempt will actually stick the landing.
As for SLS part of me wants it to explode for the oldspace cope but there is not way it gets canned and it exploding just takes more money away from other projects.

>>12583553
What are you thinking, identical failure to SN8 or something else? I have a good feeling about this one but if it fails I'm betting it crumples a landing leg at the last minute and falls over, fulfilling the prophecy of her being Tipper

Protip:

Habitable planets aren't nearly as important as you might think. If you have advanced enough technology to build a fleet of colony ships and send them off at 10% c, you probably have advanced enough technology to turn all the asteroid in your system into a massive amount of O'Neill cylinders. And once you run out of asteroids you can just starlift a ridiculous amount of matter off the sun. The most likely reason you would want to go to another star system, is to get away from the people in your home system.

>>12582899
Getting a fusion engine approved by the gov is maybe doable. a NSWR is so far out of the bounds of acceptable that it boggles the mind. These fuckers have sadly made the use of even HEU in space reactors a nightmare-they'd have a stroke at a machine powered by a continuous fission reaction.

>>12583556
It'll be something new, I'm thinking engine throttling as that never really got tested on SN8 due to it going oxygen lean and engine rich.

>>12583564
>The most likely reason you would want to go to another star system, is to get away from the people in your home system.

The original Ares I/Orion plan was a lot better. In this, Orion was designed to have three variants. There was the manned one we all know and love. There was also an unmanned variant that still has the capsule (think of it like a gigantic version of dragon). The third and final version of Orion had the same service module as the first two but a giant cargo module like Cygnus (but fatter). Ares I was supposed to fly 4-6 times per year.

>>12583580
SRB’s are expensive thought. From what I understand (correct me if I am wrong) SRB’s were used in the early days because they were cheap. But now for some reason they cost a fuck ton. Could a solid rocket motor be made dirt cheap if it was made by someone like spacex?

>>12582898
How many full sized prototypes did they make for SLS?

>>12583593
They made a flight version core stage but never mated it and instead popped the two tanks for pressure tests.

>>12583587
>But now for some reason they cost a fuck ton.
SRBs are still cheaper than cryogenic engines. It's just that reusable liquid fueled rockets are even less expensive.

>>12583587
I'm sure a competent aerospace company could produce super cheap SRBs. Still you are throwing them away every launch since there isn't any real mechanism to reuse them.

>>12583616
>since there isn't any real mechanism to reuse them
Then make one

>>12583623
Solid rocket port tail fin to orbit when bros?

>>12583623
It's not about bringing it back. You can't refuel them like you can a liquid rocket, each time you have to essentially rebuild it. Also I'm no rocket scientist but I bet solid fuel is a shitload more expensive than methalox.

dumb question: when you watch rocket engines fire the flame isn't just a 100% neat flame. There are always streaks that emerge and then quickly disappear. Even very clean burners like the raptor and SSME have periodic orange streaks. Are these streaks combustion instability that quickly resolves itself or what?

Before answering that you should first address the issue of atmosphere.

>>12584001

>>12583995
People are speculating a few things
1) The Raptors are actually in good shape, but Elon and the team want them to be better. Apparently any issues with the Raptors happened after the first burn, but SpaceX was still cool with firing them two more times. This, combined with the delay to announce the Raptors being taken off likely means that there was A LOT of data review. It’s likely that the Raptors are good, but not quite 100%.
2) It seems like SN9 is specifically designed to test the landing. This makes sense because it’s the one thing that SN8 didn’t get quite right. It’s okay to lower the apogee because all you need is a bellyflop. The lower apogee also gives less of a chance for a Raptor to blow up or fail in flight, too.
3) SpaceX is being extra cautious with SN9 BECAUSE of optics. SN8 did so well that anything less would be a disappointment. SpaceX wants the best engines for the job, and they want the highest chance of a successful landing. My personal theory is that SpaceX is trying to show off for the HLS down select because SN9 might be the last Starship flight before the decision of which HLS to fund. You bet your ass they want a successful landing.

Replace matching speed with the ground with matching speed with the ship, you dummy.

>>12583572
>I'm thinking engine throttling as that never really got tested on SN8
The engines were continuously throttling down during the entire ascent, dude. They'd throttle down until they hit minimum settings, then one of the engines would cut off and the other two would throttle up a bit to maintain the same acceleration. This was done because as propellants were used the vehicle got lighter and lighter, but they didn't want to run out of propellant while still moving upwards.

>>12583601
No they aren't, they're only cheaper than oldspace engines. Raptor blows the fuck out of any solid booster in terms of thrust per dollar, even if you include the structural mass of the tanks etc.

>>12583980
>Since Nitrogen is hard to get at least for now
Mars' atmosphere is 2% nitrogen and any Starship-based colony is going to be harvesting many thousands of tons of that atmosphere annually, which means many dozens/hundreds of tons of nitrogen by-product. Nitrogen is not hard to get on Mars.

>>12584242
Actually in starlifting you're just taking all that material from the star and sifting out the ~1% non-hydrogen-non-helium stuff, then putting the H2 and He somewhere else. It's still retarded.

>>12584263
Yeah it will. Lunar Starship needs the SL engines because during launch from Earth in the first place it needs the thrust of at least 6 Raptors total to achieve orbit in time.

>>12584528
I'm starting to think you have brain damage.
Matching speed with a constant velocity on the Earth's surface while hovering over it means actively maintaining that velocity vector. You don't just "match speed" and suddenly share a frame of reference like it's orbit, at any point in your hover you are actually on a parabolic arc which does not have a constant velocity vector relative to your moving target. Do you understand?

It doesn't unless I'm blind

>>12584582
You know Starship is the second stage, right retard? When it lights it will be practically vacuum. You are a dumb fucking anon

>>12584588
It's literally the same, are you ok?

>>12584599
You know it needs to have enough thrust to accelerate quickly enough that it can circularize before passing apoapsis and falling back into the atmosphere, don't you retard?
This is why launch vehicle second stages need a TWR of at least ~0.8.

Official Lunar Starship render from SpaceX, note the three SL and three Vacuum Raptors on the base. Now fuck off.

>>12584605
Guess what type of engines they will be, retard. Okay okay I'll give you a hint. Ready? Not fucking sea level engines. You mouthbreathing troglodyte

>>12584600
Alright anon, fine. You live in a different world. It must be nice to maintain constant velocity without input energy despite not being in a fucking vacuum.

>>12584614
Uh-oh, pal. I have a render too. Renders are real reflection of what will happen in reality. Fucking destroyed and debunked

>>12584614
>believing official renders

>>12584614
I'm not saying it's gonna have vacuum engines in the final version, I was just complaining about the renders having them.

>>12584605
It'll have a whole lot of speed from the superheavy, will it really need to fire its atmosphere engines as well as its vacuum engines? Wouldn't that just be wasting fuel? Three vacuum raptors firing full blast is gonna produce a lot of thrust.

>>12584622
Wind doesn't matter for a slow moving platform, because wind also exists when you're trying to land on land.

>>12584618
They will be 3 Sea level and 3 vacuum Raptors.
>>12584623
That's from 2016 and shows the ITS landed on Enceladus. I posted a render of HLS Starship landing on the Moon which was posted by SpaceX last year.

>>12584654
It won't be enough thrust, and it won't be moving fast enough. The Booster is gonna separate at a couple km/s, which is enough that if Starship did nothing it would fall back down after about a minute or two of parabolic arc.
Fully loaded Starship masses >1500 tons. Starship with zero payload and enough propellant to reach LEO would mass ~1200 tons. Raptor produces ~200 tons-force of thrust, meaning six of them firing at once would allow Starship to hover (maintain a TWR of 1).
Basically, yeah, Starship will absolutely need all 6 engines firing at once during the burn to orbit. At some point during ascent it's likely that the SL engines will shut down and the rest of the burn will be completed with the vacuum engines, but that can only happen once TWR and gravity loss factors minimize.

>>12584664
>they'll just compensate because it's a trivial problem
Meanwhile BO cannot compensate because it's not a trivial problem, lol. Hovering is so retarded compared to a suicide burn.

>>12584654
>Wouldn't that just be wasting fuel?
It's not wasting fuel vs. not wasting fuel. It's wasting fuel through gravity losses (lower thrust) vs. wasting fuel through inefficiency (underexpansion).

>>12584682
TWR doesn't matter once you're out of atmosphere and going approximately sideways, you only need enough time to burn to orbital speed without reentering

>>12584713
At some point you have to give up and tell a motherfucker to go play KSP. This is that point here.

wait a minute...you're telling me they broke TWO raptors?? so anon was wrong, he said they would only replace one. get fucked doomer anon
