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.

Ship Location Status Comment
Pre-S24 Scrapped or Retired SN15 and S20 are in the Rocket Garden, the rest are scrapped.
S24 In pieces in the ocean Destroyed April 20th: Destroyed when booster MECO and ship stage separation from booster failed three minutes and 59 seconds after successful launch, so FTS was activated. This was the second launch attempt.
S25 Launch Site Testing On Feb 23rd moved back to build site, then on the 25th taken to the Massey's test site. March 21st: Cryo test. May 5th: Another cryo test. May 18th: Moved to the Launch Site and in the afternoon lifted onto Suborbital Test Stand B.
S26 Rocket Garden Resting No fins or heat shield, plus other changes. March 25th: Lifted onto the new higher stand in Rocket Garden. March 28th: First RVac installed (number 205). March 29th: RVac number 212 taken over to S26 and later in the day the third RVac (number 202) was taken over to S26 for installation. March 31st: First Raptor Center installed (note that S26 is the first Ship with electric Thrust Vector Control). April 1st: Two more Raptor Centers moved over to S26.
S27 Rocket Garden Completed but no Raptors yet Like S26, no fins or heat shield. April 24th: Moved to the Rocket Garden.
S28 High Bay 1 Under construction February 7th Assorted parts spotted. March 24th: Mid LOX barrel taken into High Bay 1. March 28th: Existing stack placed onto Mid LOX barrel. March 31st: Almost completed stack lifted off turntable. April 5th: Aft/Thrust section taken into High Bay 1. April 6th: the already stacked main body of the ship has been placed onto the thrust section, giving a fully stacked ship. April 25th: Lifted off the welding turntable, then the 'squid' detached - it was then connected up to a new type of lifting attachment which connects to the two lifting points below the forward flaps that are used by the chopsticks. May 25th: Installation of the first Aft Flap (interesting note: the Aft Flaps for S28 are from the scrapped S22).
S29 High Bay 1 Under construction April 28th: Nosecone and Payload Bay taken inside High Bay 1 (interesting note: the Forward Flaps are from the scrapped S22). May 1st: nosecone stacked onto payload bay (note that S29 is being stacked on the new welding turntable to the left of center inside High Bay 1, this means that LabPadre's Sentinel Cam can't see it and so NSF's cam looking at the build site is the only one with a view when it's on the turntable). May 4th: Sleeved Forward Dome moved into High Bay 1 and placed on the welding turntable. May 5th: Nosecone+Payload Bay stack placed onto Sleeved Forward Dome and welded. May 10th: Nosecone stack hooked up to new lifting rig instead of the 'Squid' (the new rig attaches to the Chopstick's lifting points and the leeward Squid hooks). May 11th: Sleeved Common Dome moved into High Bay 1. May 16th: Nosecone stack placed onto Sleeved Common Dome and welded. May 18th: Mid LOX section moved inside High Bay 1. May 19th: Current stack placed onto Mid LOX section for welding. June 2nd: Aft/Thrust section moved into High Bay 1. June 6th: The already stacked main body of the ship has been placed onto the thrust section, giving a fully stacked ship.
S30+ Build Site Parts under construction Assorted parts spotted through S34.
Booster Location Status Comment
Pre-B7 & B8 Scrapped or Retired B4 is in the Rocket Garden, the rest are scrapped.
B7 In pieces in the ocean Destroyed April 20th: Destroyed when MECO and stage separation of ship from booster failed three minutes and 59 seconds after successful launch, so FTS was activated. This was the second launch attempt.
B9 High Bay 2 Raptor Install Cryo testing (methane and oxygen) on Dec. 21 and Dec. 29. Rollback on Jan. 10. On March 7th Raptors started to be taken into High Bay 2 for B9.
B10 Rocket Garden Resting 20-ring LOX tank inside High Bay 2 and Methane tank (with grid fins installed) in the ring yard. March 18th: Methane tank moved from the ring yard and into High Bay 2 for final stacking onto the LOX tank. March 22nd: Methane tank stacked onto LOX tank, resulting in a fully stacked booster. May 27th: Moved to the Rocket Garden. Note: even though it appears to be complete it currently has no Raptors.
B11 High Bay 2 Under construction March 24th: 'A3' barrel had the current 8-ring LOX tank stacked onto it. March 30th: 'A4' 4-ring LOX tank barrel taken inside High Bay 2 and stacked. April 2nd: 'A5' 4-ring barrel taken inside High Bay 2. April 4th: First methane tank 3-ring barrel parked outside High Bay 2 - this is probably F2. April 7th: downcomer installed in LOX tank (which is almost fully stacked except for the thrust section). April 28th: Aft section finally taken inside High Bay 2 to have the rest of the LOX tank welded to it (which will complete the LOX tank stack). May 11th: Methane tank Forward section and the next barrel down taken into High Bay 2 and stacked. May 18th: Methane tank stacked onto another 3 ring next barrel, making it 9 rings tall out of 13. May 20th: Methane tank section stacked onto the final barrel, meaning that the Methane tank is now fully stacked. May 23rd: Started to install the grid fins. June 3rd: Methane Tank stacked onto LOX Tank, meaning that B11 is now fully stacked. Once welded still more work to be done such as the remaining plumbing and wiring.
B12 High Bay 2 (LOX Tank) Under construction June 3rd: LOX tank commences construction: Common Dome (CX:4) and a 4-ring barrel (A2:4) taken inside High Bay 2 where CX:4 was stacked onto A2:4 on the right side welding turntable. June 7th: A 4-ring barrel (A3:4) was taken inside High Bay 2. June 8th: Barrel section A3:4 was lifted onto the welding turntable and the existing stack placed on it for welding. June 9th: The next 4-ring barrel (A4:4) was taken inside High Bay 2, later in the day the incomplete LOX tank stack was hooked up to it and placed on the welding turntable for stacking and welding.
B13+ Build Site Parts under construction Assorted parts spotted through B17.

So relieved to see a Starship Tech thread here. It's the only thread I check daily without fail. Thanks @[email protected]

Steel sheathing going up on the tower at 10:40AM CDT on Starbase Live.

[–] [email protected] 5 points 1 year ago (1 children)

Are they replacing sheathing that was damaged during the first integrated flight test, or are they adding sheathing to part of the tower that never previously had sheathing?

[–] [email protected] 6 points 1 year ago

New. They already took a few of the old panels off and then put them back.

I think most of us had a general sense of this already, but Elon stated next flight in "6 - 8 weeks":
