Fair point - they didn't even plan a landing for the Spaceship, just a splashdown in the Pacific, so the plan was always to "lose" it. And it was well on track for that, it reached target height and already fired about 90% of its fuel. The only thing it didn't get to test was the heat shield, but there'll be plenty of other chances. I'm sorry about the booster tho. But overall it's hard to consider this anything othe…

any footage of the splashdown ?

Did you miss the part where the first stage exploded and they lost communication with the second stage?

There is no footage for that.

I hope that future mission commanders will never ever let control forget that someone mistakenly kaboomed an upper stage.

I believe it was automatic based on a potential course deviation that brought it dangerously close to Hawaii?

Well... that'll teach them pesky nav-bots to threaten populated areas.

Did the Saturn V turn around, come back and land, and then be used again for another launch? Maybe I missed that part?

Did 'Starship'?

Will* Starship? Yes. And doing so is an order of magnitude more complex than Saturn V.

I’m old enough to remember the Apollo program. Not one Saturn V blew up on launch. I guess we had a different notion of “success” back then.

Yes, but the approach is very different. This more of a '(star)ship and iterate' way of working. There's also the cost factor - each Saturn launch was around $1.5 billion in today's dollars. Whereas the projected budget for Starship for the entirety of 2023 was around $2 billion. Once they start launching commercially then Musk expects a launch to come down to around $10 million - even if he's wildly out then it's st…

When an iteration entails 200 tanker loads of fuel and oxidizer, 39 rocket engines, and a giant steel rocket, and the iteration takes 7 months, with Artemis 1 having flown a year ago, this is also why agile everything is a bad idea.

The early history of rocketry was non stop blowups, I mean hundreds of them. You can watch edits of this on youtube. Rocket science is hard hence "It's not rocket science", except it is. Having money and smart people doesn't ensure success. Bezos started his company before Musk did Space X and they still haven't gotten to space.

And it's science that fails spectacularly. If I utterly fail at a Computer Science, there's no giant explosion.

If you use auto scaling services and fail to limit a recursive call to a service. You can create a giant explosion aimed at your bank account.

I'm going to assume you made this comment in good faith. Most rockets (almost all) use just a few engines. The Saturn V had five engines, and the Space Shuttle had a total of five engines (including the Solid Rocket Boosters). The Atlas V uses one engine, New Glenn seven engines, etc. Historically, there has only been one rocket that attempted the 'many engine' approach before now: the N1 by the Soviets, which they n…

Thanks for the genuine response, it wasn't a troll comment.

I was also genuinely interested in your simple question, "what makes the functioning of all the engines so difficult?"

You received a response with many words but I don't think it contains a real answer, other than "the Soviets couldn't do it".

Isn't reentry supposed to be the hard part? How was this a success?

The largest rocket ever built just got to space for the first time. Even without re-entry this is a milestone. They have a production line to build these things. They’ll roll out the next one and try again. It’s not like SLS where everything is expected to work perfectly.

Why is the size a milestone? I don't remember ever hearing NASA measure its achievements by the size of its rockets.
