[Closed] SpaceX starship high altitude test

Planned on having 2 on the way down, but didn't look to be running right.

I think it lost 2 on the way up, and only 2 re-lit on the way down

Deliberately switched off and moved to the side I believe

Got to be something like that. To the uneducated (me) it just looks like they hit the brakes too late, but that would be far too simple an error for the brains involved in this stuff!

I’ve had a few landings like that playing Elite Dangerous.

That was amazing to watch. Even the first flip and the way the ship descended in a stable manner before they rotated it again was incredible.

There was bigger all pressure in that for the landing. Amazing performance overall though

Great tele. A take off, flight, controlled descent the muckle big explosion!

From the Apollo stuff I've read, rockets are not so easy to turn on and off or throttle - you wonder how it would have gone if all three fired up on request.

Still cool! 🙂

I believe that those raptor engines are actually designed to shut down and refire repeatedly. It’s basically methane & oxygen lit by a spark plug

Assumed 1 engine on landing was as planned given a falcon 9 can only land on 1 engine albeit 3 can restart

Those poor kerbals 🙁

Good viewing though. Lots of succesful operations, the rotations were cool, it damn nearly makes it down and then, a satisfying explosion to close. Pretty ideal.

It's **** all compared to UK Space Command.

The "spkunk works" is working on a project featuring a repurposed Sinclair C5.

2022 son you better believe..........

Fuel header tank pressure was low, that'd do it when you're needing fuel for your brakes

I wouldn't have known about it, if it hadn't been for this thread; STW delivers again!
It is properly impressive stuff......however.......the landings I've seen always look a little fishy, like cameras turning off at JUST the right second, in this case, the camera position seemed to switch exactly at the moment it exploded, so it just looked badly edited, then the comment about "Great work everybody". I'm not one for conspiracy theories at all, it just looked a little odd, that's all.

I think you're talking about the landings on the drone ships. That's because just as the boosters land they make the drone ship move which breaks the microwave link between the drone ship cameras and the other manned vessel nearby. They've since improved the robustness of this link so that the video link is no longer broken and you can see the actual landing. All the touch downs they have made on land you can see the actual moment of landing.

Probably more to do with editing out something they don't want people seeing. Bear in mind there could be a lot of proprietary stuff in testing. Either that it's a glitch from a rocket blowing up right next to it.

Someone needs to play some more Thrust.

Just watched. Indeed great telly. Skip to 25mins for the action.

however…….the landings I’ve seen always look a little fishy, like cameras turning off at JUST the right second,

You could go to Florida and watch it if in doubt (not sure of this one was Florida admittedly, probs want to check that in advance)

It was in Nevada

Musk is one of our greatest living humans

no, he’s a terrible ****

It was in Nevada Texas

God, don't suggest that to Musk, if he decides a project's too hard he'll just blow up a power plant then fly off into space.

Delta 4 launch was pretty impressive 🚀

Revisiting this as SN9 is up for test launch for today although suggestions already that now postponed to Friday?

Yeah, sounds like still waiting for approval from FAA

Looks like tonight.

I'm looking forward to this launch.

Live stream from SpaceX, so should be on

NASA spaceflight.com stream for me, then I'll look at the other feeds later.

Hasn't blown up yet!

Nearly!

Bang

Boom

Oof ! Fire the boosters earlier.....

Awesome stuff. Brilliant flight, massive explosion. Perfect

Amazed they landed so close to the second rocket, that send a risk not worth taking.

Incredible camera shot in the last few seconds of flight

Also love the Spacex commentator. “Successful flight, need to work on the landing a little bit!”

Spacex showmanship innit.

So what happened there, only one booster relit? Seemed to go pretty well otherwise

It was to warn SN10 what would happen if it misbehaved.
Oi, rocket. See what happened to your mate there? Yeah, well no ****ing around when you come into land, OK?!

Oh well, they'll get there... Send up sn10 😬

2nd raptor engine failed to relight correctly if i heard right

Ah I got caught off guard after all the cancelled launches last week I forgot about this!

That was a great watch! Big boom at the end!

Yep looks like the second engine didn’t fire up fully, you can see the 2nd engine burping a few times trying to light up properly and the single engine didn’t have the power to fully straighten up and land.

I’m guessing SN10 must be pretty much ready to go if it’s sitting so close to the launch pad. I wonder how quickly they will try to launch that?

Exciting times, makes me feel like a kid again and takes me back to when the shuttle was launching. Appeared like interest in space was higher then and we’ve had a 15/20 year lull. Great to see so many space programs happening at the same time!

SpaceX commentator said SN10 would launch 'this month'. But that was before SN9 'landed'.

I wonder how quickly they will try to launch that?

Depends on how many holes the shrapnel from SN9 punched in it

Looks pretty reliable...where do I buy a ticket?😂

Aw, missed it again! That landing pads eye view though!

"SpaceX starship" aka, Titanic.

At least there's no stowage passengers to drown this time.

Wouldn't like to be amongst the first passengers, even if I could afford a trip. Everything about space is danger danger danger.

Maybe another attempt tonight.

I hate this guy's presentation but I do like his enthusiasm. So excited just watching nothing happen

Looking good, SpaceX feed is on.

BOOOOOOOOO. Failure without explosions is the worst failure

Aborted at 0 seconds!

Boring

Damn it

Looks like it's back on. 1hr 40mins to second launch attempt.

I'll be watching

Ooh good show. Any bets?

Got to love their attitude really.  Thrust is outside limits, well just up the limits then

Yee and ha. That's how it's done

Due to try again at about 23:15 uk time

I like watching the engines gimballing about (or is it kerfing?) Very satisfying

Yes..

Agreed, it’s very bloody clever.

Nailed it! Didn't look exactly textbook but still pretty bloody impressive

Brilliant 🥳🥳🥳🥳

...bit of a lean 😬

Just awesome really

Legs collapsed apparently

Oh......

Damn, she blew ☹️

... methane leak ignited. Still, she landed.... success in my book

It went up again!

Always give the audience what they want...

"Starship to the moon" 🙂 WSB will be getting excited

From the NasaSpaceFlight stream: "Starship SN10 landed on the landing zone; then burned off the excess propellant in a rapid fashion."

Fastest launch turn around ever

Eventually got the space-x steam working and I thought I could see a little bounce at touchdown, so perhaps a little bit to fast. No springy legs like on Falcon.

The turn to vertical looked well suss on the feeds.  Who filmed that?

Still, she landed…. success in my book

Uh huh...This is success in the same way that a postie driving the van through the front of your house to deliver a letter, is success...

Almost as good as the NASA comment “ As if the flight test was not exciting enough, SN10 experienced a rapid unscheduled disassembly shortly after landing”

SpaceX website

"RUD" has been in the spacex vocabulary for a number of years!!

So what's the advantage of flipping back to vertical so close to the ground before landing?
Why not give yourself more wriggle room and do it 500 higher giving time to get all your ducks lined up?

I watched the landing this morning and thought "what are they going to do now, it doesn't look safe to go near it".

So what’s the advantage of flipping back to vertical so close to the ground before landing?

Maybe they just haven't sorted the flip fully yet? Or still needing to be horizontal for the extra drag? Difficult to know how fast it's actually going when the camera stays on it and there's no background.

As a friend described it- ‘SN10 was so happy to have landed it backflipped to celebrate’

I don't think you can throttle the engines enough to slowly descend to the ground. You have to leave it to the last second otherwise you'd start to go up again. Requires perfect timing.

Well I'm not saying you're wrong - but they hover on one engine at 10km.
(and it seems that the Raptor engine can be throttled down to about 40% thrust)
