FAQ
- When (first) orbital flight? First integrated flight test occurred April 20, 2023. "The vehicle cleared the pad and beach as Starship climbed to an apogee of ~39 km over the Gulf of Mexico – the highest of any Starship to-date. The vehicle experienced multiple engines out during the flight test, lost altitude, and began to tumble. The flight termination system was commanded on both the booster and ship."
- Where can I find streams of the launch? SpaceX Full Livestream. NASASpaceFlight Channel. Lab Padre Channel. Everyday Astronaut Channel.
- What's happening next? SpaceX has assessed damage to Stage 0 and is implementing fixes and changes including a water deluge/pad protection/"shower head" system. No major repairs to key structures appear to be necessary.
- When is the next flight test? Just after flight, Elon stated they "Learned a lot for next test launch in a few months." On April 29, he reiterated this estimate in a Twitter Spaces Q&A (summarized here), saying "I'm glad to report that the pad damage is actually quite small," should "be repaired quickly," and "From a pad standpoint, we are probably ready to launch in 6 to 8 weeks." Requalifying the flight termination system (FTS) and the FAA post-incident review will likely require the longest time to complete. Musk reiterated the timeline on May 26, stating "Major launchpad upgrades should be complete in about a month, then another month of rocket testing on pad, then flight 2 of Starship."
- Why no flame diverter/flame trench below the OLM? Musk tweeted on April 21: "3 months ago, we started building a massive water-cooled, steel plate to go under the launch mount. Wasn’t ready in time & we wrongly thought, based on static fire data, that Fondag would make it through 1 launch." Regarding a trench, note that the Starship on the OLM sits 2.5x higher off the ground than the Saturn V sat above the base of its flame trench, and the OLM has 6 exits vs. 2 on the Saturn V trench.

New comment from /u/santacfan on Reddit:
Starbase live-
1:54am- LR11000 disconnected from the y pipe
2:51am- Little crane lifts what appears to be a stand out of the pit
2:57am- What looks like a short piece of pipe is lifted into the pit
3:51am- Stand lowered into the pit
4:00am- LR11000 swings over and lowers it’s hook into the pit
4:39am- Grover lifts more rebar over for the cryo pit lid
4:50am- Another load of rebar is moved over
4:58am- 3rd load of rebar moved. That’s going to be one beefy lid
9:42am- Grover lifts what may be one of the extra deluge plate extensions over to the gap by the new stairs
9:59am- Swung back over to the side and sat down
10:07am- Grover lowers
11:14am- Concrete being cut
11:15am- Grover shows off and swings the extension plate back over to the OLM while lowered.
11:38am- Plate lowered. Lines go slack.
11:40am- Raised back up
11:47am- Lowered back down
11:57am- Picked back up and swung off to the side again
12:53pm- Generator removed from the pit
1:24pm- Basket goes up
1:31pm- LR11000 unhooks from whatever it was attached to (Most likely the Y pipe)
1:33pm- Basket goes down
2:07pm- Grover starts to remove it’s counter weights to move (Maybe to Masseys to lift B10?)
2:13pm- Grover removes more weights
2:18pm- More weights moved over to an SPMT
2:23pm- There goes another
2:24pm- LR11000 takes tension on its lifting straps
2:38pm- LR11000 lifts another deluge pipe. Grover removed 4 more weights
2:41pm- Pipe is raised higher and swung over OLM
2:48pm- Pipe starts lowering
2:58pm- Pipe is sat on the ground and the LR11000 is unhooked
2:59pm- Small crane hooks to the pipe
3:05pm- Pipe is swung over towards the left most manifold. So looks like it’s the left side of the Y. If the piece lifted early this morning was the right side, this should be the last piece to go around the OLM. Now we need the 2 feed pipes from the concrete bunker over.
3:05pm- At the same time, Grover lowers.
3:38pm- Grover drives away
4:43pm- The LR11000 drives away from the OLM
5:35pm- Small crane moves into the area that the LR11000 was sitting
7:34pm- Chopsticks lowered. Indicating all of the big lifts on the right side and behind the OLM are finished
8:04pm- Extension piece (?) lifted back over towards the OLM.
11:00pm- Pretty quiet evening from what we can see. I’m sure the welders are hard at work. I’ll be watching for more rebar to go in the pit to signify that they are done and the pipes are ready to be buried.
