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.

Congrats to SpaceX for completing & documented the 57 items required by the FAA for Flight 2 of Starship!
Worth noting that 6 of the 63 items refer to later flights.
A readable text version of the 63-item list can be see on Reddit here and a reply.
I copied and pasted it here. Thanks to @[email protected] for pointing me back at the RES extension so I could get the source.

I can’t be bothered to try to make it a table here. (I don’t know if or how it can be done
Reddit and Lemmy markdown are almost identical, so you should be able to copy it over with minimal formatting changes.

Huh, I wonder why they’re removing the hot staging ring. Further upgrades to the ring following the B9+S25 stack test? Better access to the top of B9?
I posted here about the FWS environmental re-assessment due to the booster bidet.
