Just watching the live-stream, does SpaceX only hire young guys in their 20's?

>Just watching the live-stream, does SpaceX only hire young guys in their 20's? Basically. It's a rough work-life balance at SpaceX and as people get older, they want to live their lives and not live at work.

Summary: almost, but not quite entirely successful. Launch successful. Booster separation and boost back burn looked good. Booster failed to relight some of its engines and hit the water hard. Successfully deployed the 20 starlink satellites. Successfully reignited an engine in flight to prove potential for de-orbit burn on future flight. Re-entry looked good and less spicy that some previous attempts (subjective). S…

Speaking of which, are there any fan theories on why the boosters seem to have persistent issues? Or is the plumbing still churning fast enough that we keep seeing N=1 issues for successive designs?

Until the past couple launches it was the ship that had the issues. Had to be blown up a couple times, failed to relight in vacuum, lost an engine and nearly failed to get to the suborbital trajectory last time. Meanwhile the booster had the most spectacular success in the catch, and has yet to result in a catastrophic failure.

I guess they also failed to explode it

from what i understand it kind of is a failure. It's suppose to tip over, explode, and sink. That way you don't have all this ITAR regulated tech floating around in international waters.

They actually said they’ve been trying different techniques to not have it explode like rolling.

This way they got way more heat shield data, which is, I think, their most critical item they need to learn from and iterate.

Yup. Some of the Youtubers (like NASA Spaceflight) had video of it hitting the water pretty fast and hard. That said, this is the only test failure so far. I'm cautiously hopeful they get Ship to touch down. (it will explode after it does because of physics but stepping lightly onto the ocean will be a win)

How many times have they managed to catch it in the last 8 or so missions? There have been a few misses like this already with the boosters

They only tried to catch it twice, and they caught it twice.

Whoa the acceleration from the start surprised me. It’s huge and it just … zipped off the pad like a bullet (ok not real bullet but still).

Given how little payload is onboard at the moment, what an empty can starship is, i sure hope for their sake there is a lot a lot a lot of zip to spare right now.

Yet here you are, doing it. Reminder: > "pedo boy" sounds like an insult, not a charge... This is evident from you changing his word from "pedo boy" to "pedophile".

I don't consider "pedo boy" to be slander any more than someone in the west calling another a "motherfucker". It's not actionable, and the lawsuit alleging it to be libel failed for that reason.

>I don't consider "pedo boy" to be slander any more than someone in the west calling another a "motherfucker".

'motherfucker' is a common phrase even outside of strictly english - speaking countries , and very few people go on to explain how the person had sex with a mother.

'pedo boy' is impossibly uncommon, regardless of what the singular defending belligerent claims, and furthermore he went on to publicly accuse the person of actual pedophilia.

yeah : i'm sure it didn't fail in court due to unlimited deep pockets and lawyers on retainer.

is there anything beyond willful ignorance ? You and I have had differences of opinion before, but yeesh -- talk about a hill to die on, defending elons' shite behavior during that phase.

Lots of missing tiles still. Best case is it's all infant mortality and replacing just those tiles will result in a durable heat shield for many more flights. Worst case is every flight loses that many tiles and the ablative underneath can't be reflown until replacement. I wouldn't be surprised if we end up seeing a heat shield refurbishment attachment to the launch tower that allows technicians to access the side of…

Musk tweet: “We got all the heat shield data we needed and then some! ” https://x.com/elonmusk/status/2080812297694409014

Also they plan to catch the ship next time! Excitement guaranteed!

and costs taxpayers billions compared to our working models 60 years ago. Great innovation

I remember the Saturn V being caught by chopsticks in mid air too. Starship is fantastic value for money compared to Artemis!

Saturn V didn't take 8 launches and 9 orbital fueling operations to get to the moon.

>> Stainless steel is just such a terrible choice for a rocket this large. Honest question, but what do they usually use?

Aluminum alloy and carbon fiber, because both have high strength to weight ratios. Steel is denser, so its specific strength isn't as high. But it retains strength at both lower & higher temperatures, and it's much cheaper. It's also cheaper/quicker to modify a steel design, as welding is easier than aluminum (at least for low carbon steels used in Starship). And if the same structure were made of carbon fiber, it wo…

you should come back to this comment in 10 years. stainless steel starship will not have left LEO.
