Landed it and blew it up - it's the perfect spectator outcome, really!

I called my wife over to watch this live and said "Wanna see a spaceship blow up?", it landed fairly ok (I knew it was a bit hard) and was sitting like the leaning tower of piza, but it landed. She walks off disappointed...
Yeh she missed it ;p

It was incredible though, and they let it right itself at 500m, in freefall!? Thats insane it managed it at all.

SpaceX is the living embodiment of try, fail, learn, try again, repeat.

They deserve a lot of respect for that.

Yeah, to be clear. NASASpaceflight.com is an independent news site, not a part of NASA. (Starship itself has little to do with NASA, for that matter.) But they do great coverage of these test flights, and don't turn their livestream off right before it blows up, unlike the official SpaceX one!

Yeah I like nasaspaceflight.com, but they're nothing official in terms of NASA or SpaceX etc.

From someone who has no technical knowledge of spaceflight whatsoever.

What exploded here? Hadn't it allready landed again? Is there still so much fuel left after the landing?

I think there's a lot fuel after landing. An by "a lot" I mean "enough to be dangerous". You don't want to have your can empty when you only need a couple turns before finishing an endurance race.

The last thing you want to do is have the thing run out of fuel the second it touches down. What if atmospheric conditions or the like force you to use more fuel during the braking burn? Are you OK with running out of fuel 100m up and just regular crashing? So of course there's going to be some reserve fuel available. In an ideal world said fuel wouldn't explode shortly after landing, but we don't live in that one, unfortunately.

I think, forgetting it didn't quite work this time, the visual impact of seeing a damned rocket do stuff like that still feels like science fiction. It's simply awesome.

And I imagine part of the testing will involve landing it with fuel to see what happens. I don't know how much fuel it burns in a second of flight on its way up, but I'm sure there's always gonna be a few seconds leeway for the upward leg, meaning it's gonna have more than a few kilos of boom fluid still in when it kisses the ground....

...or Glasgow kisses it on occasion.

And then lol.

Damn I wish I could afford this for a hobby :).
You can move to Thailand. They have a yearly rocket festival. Not quite as glamorous and scientific as SpaceX of course, but if you want a lot of smoke, things shooting off platform and explosive landing as a hobby, it'll fit right in. :)

I'm still waiting for Elon to go to Mars. I can think of a few other people who could accompany him.

(I'm thinking Golgafrinchan Ark Fleet Ship B here though.)

The last two live broadcasts seemed to me to be computer graphics. And so many people have also talked about it.
It's great that real tests of space rockets can now be mistaken for graphics.
I wonder what awaits the first manned mission to Mars?

I recall his said he won't be moving to Mars even if he could, but he will allow his kids if they will want to (which I doubt - as a child of billionare I wouldn't want to go to cold desert wasteland of Mars).

Europe is starting to freak out about the launch dominance of SpaceX

What European space companies do you think can create a good alternative for Europe?
Everyone needs to launch satellites. Which companies do you see as the best? Or which ones do you root for?

Literally no knowledge when it comes to rockets, like I allready mentioned plenty of times, but I would assume a big company like Airbus Defence and Space might have an easier time breaking into the market than smaller start ups.

Airbus, Alenia, Avio are the first ones coming to my mind possibly having the know how to attempt something like this. But they're just the "famous" ones, so I'm sure a miss a lot of valid companies.
And I wouldn't exclude some engineering division from automotive.

If you still count the UK as part of Europe then Richard Branson (Virgin Galactic) would be a future candidate.

Arianespace is already there and has an excellent reputation as far as launch vehicles go, so it's really up to them to lead this competition.

SpaceX now has years of lead-time in the development of reusable rockets. Existing established players now have a lot of catching up to do after decades of relative stagnation in the launch industry, while other startups are a long way behind SpaceX's position. Established players have some reputation and reliability positives, but as Boeing has demonstrated, being a long-established, respected company doesn't necessarily mean freedom from stupid errors. And SpaceX's launch cadence means their lifetime reliability stats are rapidly ticking upwards. There's some space (ahem) in the market for, say, small satellite launchers like Rocket Lab's Electron, and big enough government agencies and companies obviously have an interest in preserving some competition in the launch market and/or indigenous capability even if that means paying for more expensive rockets sometimes. But that aside... why would you not fly with SpaceX at this point? And more to the point, how long is it going to take to get to the point that there is realistic competition again? I'm not convinced the legacy launch industry is capable of catching up at all at this point, and it's difficult to see many startups making it until one comes along that figures out how to significantly one-up SpaceX like they have the existing industry.
