I really wish they'd stop putting Musk's name on things like this. He didn't design the engines, he didn't plan the flight path, he did nothing but throw a bunch of money at a company because he's obsessed with Mars.
This just false. Sure, he did not do everything alone but he has a huge hand in engineering concepts and design decisions. Lots of hate and complete misunderstanding how spaceship, spaceX and Musk work in this thread.
Anyone who writes code knows that is not a practical way to review.
Maybe in his time he got book smart about some physics/rocket concepts. That's the least I would expect anyway. But that doesn't mean he really has any expertise to offer to the product.
This is literally rocket science. The process to put humans into space is literally done this way, for this exact reason. They had two key primary objectives for this launch:
Successful ignition and control of 33 raptor engines in first stage.
Successful hot separation into second stage.
The first stage separated entirely and gained plenty of distance before it did explode.
The second stage flew for several minutes before the automated emergency flight termination kicked in and destroyed it.
All of the data that they were recording will pinpoint the failures in the return of the first stage, and the destruction in the second stage. They would not have that data if they did not do this test and nothing went wrong.
All of the data that they were recording will pinpoint the failures
Do they need data like last time with the launch pad? Where it was clear that it will desintegrate? Did that give them additional insights into how the engines react to debris doing back into them? Was that the goal all along?
Seriously, they are iterating, sure. But we already know they ignore known problems. So it is not like every explosion is necessary or helps in any way.
I'm not a rocket scientist, but I research complex systems. Failure is the best way to improve something, even if you know it's going to fail, you want to see how and what are the repercussions. I've done so many experiments that I knew were doomed, but I still have to do them just because I wanted to see how the system is would react.
Not a fan boy of Elon by the way, not trying to defend him or anything.
Primary objective was things not to explode, which they did. Everything else you just said was repeated PR. Yes, it was a success, they wanted to throw hundreds of millions for no reason. More to the point, second stage blew up in low earth orbit, which is within reach of satellites. So your so called success is yet to be proven. It's going to be weeks and months before we see the real effect of explosion propelled debris around the planet.
Primary objective was to get further than last time, which they absolutely did. Not only were all the engines reliable for their first burn, they tested a successful hot separation, in flight ignition, and effective flight termination system. All of this was on top of the achievements they made last time and allowed Starship to reach space for the first time, making it reach past the N1 in only two attempts.
It was a great success.
PS. No it did not explode in orbit. The actual rocket scientists did think about this you know. The flight plan featured a suborbital track, and it splashed down safely in the ocean somewhere along it's predicted path at most about an hour after launch.
Actually kinda really successful 👍 All 33 engines were firing, the hot staging was successful. On both the first and second stages, it looks like the automatic FTS (flight termination system) was triggered. That would happen if it veered too far off of it's approved flight path (don't need it coming down over a populated region.) The only thing that didn't happen that I was hopeful for was atmospheric re-entry - we really need to see how that heat shield works in practice.
The launch achieved most of its objectives, but it was supposed to fly farther and splash down near Hawaii. It was a success in that the 32 engines fired together, and the ship achieved separation, and there will be plenty of data about what went wrong.
But some things did go wrong, so you can't say it was an "absolute" success. Both the superheavy and the starship were lost. Rocket science is slow and expensive progress. It's only a failure if we abandon the project. But it is disingenuous to say that everything worked out as intended.
On test flights, having something go terribly wrong is expected. This is the second test flight of a brand new vehicle system which also happens to be the largest and most complicated vehicle ever made. They also have half a dozen more vehicles already made and waiting to fly, each with improvements learned in manufacturing the previous one. They are behind their original schedule, for sure, but this mission was a huge success for SpaceX considering all of the things that did work.
It would be very weird, if we could verify they weren't shills or bots. Insane and desperate people. It was only "interesting" years ago, before he exposed himself as a fraud (and tortured animals during failed testing).
eh... it looks like hot-staging still has some bugs to work out, but the 2nd stage worked just fine (and since that's the part that matters, the end fate of the first stage is irrelevant)
What bugs? At this point we don't have an explanation for the first-stage RUD, looking at the overlay it seems there were issues re-lighting the Raptors which could be for any reason.
From what I saw, the hot-staging went perfectly with the RUD happening when the ship was already in space.
If the simulation showed a problem, they could have fixed it before launch. I'm guessing they don't have a enough data to make a super high fidelity integrated model for all phases of fight, so they'd break down the sections individually. But integration always brings extra challenges.
So they don't have a physicist on staff? Or several? We have known the math for rocket science for some time. What data is it they need? When even NASA in the sixties has simulators.
