SpaceX’s Starship rocket system reached several milestones in its second test flight before the rocket booster and spacecraft exploded over the Gulf of Mexico.
I wonder what the simulation showed was going to happen compared to the actual flight. Would give you a real metric of progress.
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.
I’m sure they have tons. But we don’t know the full thermo areo dynamics at hypersonic speeds and complex geometries, especially their effect on unconventional control surfaces across huge temperature and speed ranges. Some military companies have even bought flights on electron to get high altitude hypersonic velocity data on how the air behaves in that regime.
So rocket science…the thing the world has been doing since the end of WWII. Weird how other rockets don’t have this problem…
You know of any other companies doing a belly flop maneuver? Or a reusable first stage with hot staging?
How reusable? NASA had recoverable boosters How does math and physics change based on goals?
NASA has never used hot staging.
There’s no shame in highlighting what went right and still acknowledging what went terribly wrong.
Censoring the latter prevents improvements. No need for fanboyism.
Wow. Was not expecting that from the rocket.
What a shitty title. The lunch was an absolute success.
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. Both the superheavy and the starship were lost.
But some things did go wrong, so you can’t say it was an “absolute” success. 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.
Back to the drawing board. Yeah, I know they are with the sliderules.
I bet some of them own slide rules in homage to the people that went before them.
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.
When Elon still wrote code it was so bad they had to scrap most of it.
And the one they did use ended up into a fridge’s firmware.
He certainly didn’t have to be all anti-Semitic to deflect attention from this failure. It’s telling.
And he wasn’t! He was all white power just by hisself.
It weirds me out how many people want to get a brain implant done by a company of this guy
Look, I really want to like SpaceX and enjoy all their successes and so on.
But it’s just not. going. to. happen. And they know why. This isn’t complicated.
Care to explain why Mr. Engineer
Here’s the everyday astronaut livestream of the launch: https://www.youtube.com/live/6na40SqzYnU?t=27150
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)
good test all in all
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.
Thx for the ocean pollution!
You do realize that SpaceX is (currently) the only manufacturer that’s trying not to dump their rockets into the ocean (or wilderness/villages in the case of Russia and China respectively), right?
I was not aware, tho it’s a bit like hanging on to your cigarette butt while coal rolling as you drive from a private jet.
