re: SpaceX Starship Full Stack Test Flight Thread | Cleared Tower, Thru MaxQ, then RUD

I’m really curious as to the reason for the spin out after max Q. Some are theorizing blown out engines destroying the hydraulic gimbaling. I can imagine losing 4-7 raptors didn’t help with the slow ascent.

3 engines out at launch, and I heard they were launching at 80-90% engine throttle as well.
Here is good view of how slow it was.
The smart people keep talking there is a flip manoeuvre before booster/SS separation, but we will know more tomorrow I am sure.
They were technically launching an out-dated rocket, so some issues may have already been addressed in new booster versions.

This is like saying LSU basbeall is a failure because we lost a mid week to USL.
It’s more like WBB winning the natty this year instead of next year.
Overwhelming success. Clearing the tower was a win. Max Q gives them huge real world telemetry data. Elon will make Mars before nasa does.

That one engine "backfire" towards end of gif, was huge!

Well, NASA has already made it technically.
You are correct though, NASA will never put a human on Mars. Elon will though.

Was actually a success in their eyes as defined by their minimum goals prior to launch. They already have a new design in the factory being readied now.
I totally agree that they had success with the booster performance, and this booster is already 2-3 versions out of date.
The pad, orbital launch mount, and tank farm are destroyed though - and that is where I will say that they failed. It’s going to take months to get that repaired. Maybe they planned on the pad, but I don’t think they expected that damage to the tank farm.

This is going to buff out, do not worry

Nina Turner was reminding everyone that the government has given Musk $3 billion.
WTF do you think is resupplying the ISS?

Pour one out for the minivan. Do not know if insurance will cover this

Odds that they build a deluge system with a flame trench before the next launch?

I'd say 7/10 overall. Booster 9 will have electronic vector control which will solve the HPU issues that doomed Booster 7. I think a lot of engines went under from damage from debris at launch, so an upgraded, more reusable Stage Zero should solve a lot of that.
It was already going to be a couple month delay till next launch to get the water deluge system in. I think they'll need a flame diverter trench as well, and may have to look into making the orbital tank farm tanks all horizontal instead of vertical. Lots to consider there design wise.... But to iterative improvement and clearing the launch pad....

Now we know what happened

I would put strong money on that they cheaped out on all of these because they weren’t even sure if it would make it off the ground or not.
No need to build a state of the art full launch pad if you’re worried about it being destroyed. A MUCH smaller rocket took out the launch pad at Wallups Island in Virginia. I think it took them over 2 years just to rebuild.
I’m sure a lot of money was saved building it this way on the off chance it was destroyed. I can’t imagine SpaceX doesn’t know how to build a proper launch pad

That must be where NSF had their van too. They were checking on it but couldn't get to it. Hell, that might be there's. They mentioned it had cameras on it and from where they were it looked like the back window was toast.

That is probably a sound theory. The launch pad design was always suspect for what they were trying to do.
Mechazilla is solid, but the OLM seemed half-baked. It was probably the bare minimum they could do for the rocket.
They are now probably - Yeah that thing flew, what do we do next. The water deluge will be there for next, but it would seem that is not enough. Diverting flames and pressure will probably be needed.

I also have a bit of a theory about the rockets that failed. I don’t think all of them did….I’m sure some did….but not all.
They “failures” occurred with oddly accurate symmetry for me to think ALL of them failed. My theory is a couple failed and the systems shut off thrusters on the opposite side to help counterbalance. Too many thruster failures on one side and the rocket takes a bit of a hard turn.
I’m also willing to bet they’ll be launching these from Florida once they’re proven ready to go. No need to build a new launch pad if those are still functional. I think Starbase Texas is just for testing purposes much like how NASA used Huntsville back in the Apollo missions.

I would agree this is likely the case... but Boca Chica won't be where this thing takes off from when the missions get real
They're already building Starship/Super Heavy launch stands at the Cape where I imagine the vast majority of launches will take place once testing is done... obviously the Cape is well versed in what rockets need to reach space without destroying everything nearby
I believe Boca Chica is solely for testing

Well NASA can’t even land on the moon without Elon so I’d say this is true.
