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.

[–] SkybreakerEngineer@lemmy.world 91 points 11 months ago

He does force them to cut corners for the sake of more headlines though

[–] FlowVoid@lemmy.world 37 points 11 months ago (1 children)

Blame the poster. The CNN article itself doesn't have Musk in the headline and barely mentions him at all (there is one quote near the end).

[–] thatsnothowyoudoit@lemmy.ca 5 points 11 months ago* (last edited 11 months ago) (1 children)

Perhaps it’s time for titles that match the article headlines as a matter of policy here?

[–] stopthatgirl7@kbin.social 5 points 11 months ago

That is already the rule. CNN changed the headline after I posted it.

[–] Agent641@lemmy.world 5 points 11 months ago

He did insist they slap an X on it tho. Thats gotta be worth something, right.

[–] yoz@aussie.zone 4 points 11 months ago

Sadly, Thats how capitalism work hence they keep using Musk's name. Anyone with money is valuable in our economy.

Alright, let me clear something up.

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:

  1. Successful ignition and control of 33 raptor engines in first stage.
  2. 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.

[–] Eheran@lemmy.world -1 points 11 months ago (1 children)

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.

[–] Eheran@lemmy.world 1 points 11 months ago

That was really non of that. It was predictable that and how it would fail. NASA etc. solved that issue decades ago. It also created new issues, like the (protected) water table being affected. All because he wanted a certain date and cheap out.

So, actually kinda successful.

[–] MumboJumbo@lemmy.world 45 points 11 months ago

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.

What a shitty title. The launch was an absolute success.

[–] themeatbridge@lemmy.world 15 points 11 months ago* (last edited 11 months ago)

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.

Did he blame the Jews for it blowing up?

Well that tweet is being composed with the aid of kilos of ketamine as we speak

[–] WhyYesZoidberg@lemmy.world 5 points 11 months ago

The space lasers took it out probably

[–] Illogicalbit@lemmy.world 18 points 11 months ago* (last edited 11 months ago)

lol: “experienced a rapid unscheduled disassembly”. That’s one way to describe it!

[–] Vakbrain@lemmy.dbzer0.com 15 points 11 months ago* (last edited 11 months ago)

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.

It weirds me out how many people want to get a brain implant done by a company of this guy

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

[–] neveraskedforthis@lemmy.world 5 points 11 months ago

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.

Here's the everyday astronaut livestream of the launch: https://www.youtube.com/live/6na40SqzYnU?t=27150

[–] iterable@sh.itjust.works 5 points 11 months ago (1 children)

I wonder what the simulation showed was going to happen compared to the actual flight. Would give you a real metric of progress.

[–] JohnDClay@sh.itjust.works 2 points 11 months ago (13 children)

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.

Explosion at T+03:20

[–] xc2215x@lemmy.world 1 points 11 months ago

Wow. Was not expecting that from the rocket.
