FAQ

  1. 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.”
  2. Where can I find streams of the launch? SpaceX Full Livestream. NASASpaceFlight Channel. Lab Padre Channel. Everyday Astronaut Channel.
  3. 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.
  4. 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.”
  5. 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.

I’ll attempt to keep this post current with links and major updates, but would be greatly helped by information supplied by the community. I hope this can be an alternate place to discuss Starship development. While the Starship Development Threads on Reddit are not party threads, Lemmy is still small enough that I don’t imagine that strict moderation will be needed in the short term.
