Pad Damage Inspected after Booster 7 Static Fire​


After firing 14 Raptors 2 motors at the same time something had to feel the effects. 14 is more thrust than Falcon Heavy, and that's less than half the motors they'll launch with 33 is going to be a hell of a show.

that's great news, i had a really bad feeling about that launch.
Ain't over yet.
We won't know until December 11 whether the heat shield can withstand reentry at trans-lunar velocities after being in deep space for 26 days.
Probably good to go... that technology got ironed out pretty well 60 years ago, to the point that some Apollo crew members indicated that they were uncomfortably cold during reentry.

Biggest concern is RCS hardware, and navigation programming issues like those encountered on the Starliner.

fully realize this is just, it made it into space is all. any missile can do that. :D

well, yes and no. Any ordinary missile can do that. This is a bit more than ordinary. It is the most powerful flying bomb ever launched. It performed its function, to direct the slow motion explosion out its arse. This had so many ways it could have gone tits-up. It performed brilliantly. Nothing of this power has ever been launched out of our gravity, not even the venerable Saturn V-5.

yep, and so far it's performed better than the ordinary missile.

it has a long way to go, and i'm hopeful for it's ultimate success. the data from the cabin will be interesting both in G's and temps. that capsule finished "testing" many years ago and never went to orbit iirc.

Using very old engines and very old SRB tech...with one extra segment. Hardly revolutionary.

Exactly.
Legacy hardware from the shuttle, just added another engine and enough fuel to extend the burn time.
Add an Atlas 2nd stage and that's all she wrote.
Impressive machine, but technologically, not that impressive... it could have been done in 1984 with off-the-shelf hardware.

What pisses me off is all of that legacy hardware was and is reusable, and much of it has already flown on shuttle missions.
So it's all integrated into Artemis, and will hopefully launch a manned crew to repeat the current mission, but at that point, the legacy hardware is gone, and an entirely new SLS will need to be built.

Given how long it took to get the current SLS off the ground, we're going to be lucky if Artemis-3 flies before 2030.

Artemis 2 has been pushed to 2025.

Yep... The current SLS project has been a big waste of resources that should have been directed at a long-term sustainable project.
How much of the current systems will be able to be integrated into the final revision? Maybe the core stage tanks can be used? Most likely the thrust structure will need a complete revamp.
The original concept called for liquid fueled strap-on boosters, a/la Delta IV Heavy.
Still the plan for the final version?

The Delta's have been amazing, but we need to be reusable. I really hope Starship (in some form) takes off...pun intended.

Dropping those motors in the ocean 4 at a time. Oh well, don't have to worry about the next 4 till 2025.
And no attempt to recover the SRBs, which were also reusable on the shuttle, though I don't believe these lower sections had flown before.
