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.

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.
Should we now be creating thread #47?
Sounds good. Would you like to do the honours, or shall I?
The Reddit Starship Dev thread is semi-publicly editable by via a Reddit wiki page. Do you know if Lemmy has similar tools? Some way for multiple people to update the post would certainly be useful…
Edit: I have created a new thread.
#To repeat, new pinned thread:
As @clothes on lemmy.world pointed out: for some reason, via lemmy.world, this 46B thread is still pinned and there’s no sign of 47.
Unrolled tweet thread at threadreaderapp.com by Ryan Hansen Space @RyanHansenSpace. It’s a look at the details of the steel plate parts and assembly under the Orbital Launch Mount.
I’m really impressed by how quickly the plate is getting assembled. I didn’t expect the manifolds to get added for another week or so, and now they’re at 2 / 3.
I’m not sure what the bottleneck is at the moment. Once everything is lifted in place they can move B9 over, but they might want to wait until they hit stage adapter is added.
B9 could go through spin prime tests without the plane being ready, and the plate can get tested without all deluge water & gas tanks present. We’re also it sure how far along the other OLM repairs are (cryo pipes are still being replaced). So there’s a ton of stuff happening in parallel.
Musk said that he thought that FAA approval of a new FTS design was likely to be the long pole.

Starbase live-
11:56pm- 2nd manifold is lifted off it’s stand (Who needs sleep anyways)
12:12am- Manifold is going up after some weight was added to balance the load
12:14:40am- Starts to swing over
12:18am- Lowering. This should go to the left of the plate installed earlier
12:23am- Trying to get it aligned
12:25am- Starting to bring it in closer to the OLM
12:31am- Lowered a bit more. (Looks like they’re at the 10ft mark where they paused for quite a while earlier. So I’m off to bed)
12:45am- Lowered into place.
1:21am- Raised again
1:50am- B10 turns into Massey’s

5:30am- LR11000 is disconnected from the manifold section
8:10am- Day shift off to a slow start
9:25am- White pipe is lifted by a small crane over by the berm. RGV’s pictures show that they might be running a new water line from the current vertical tank over to the OLM.

11:04am- Basket goes up
11:21am- Retaining wall goes up where they’ve been excavating

2:11pm- LR11000 lifts another counterweight
2:17pm- Small crane lifts a piece of metal out of the excavation pit
2:53pm- In todays adventure of what’s stuck at Starbase. We have a small bulldozer hanging off the side of a low boy trailer.
2:53:54- Random kid says hi
2:58pm- The excavator wins again. Bulldozer is on the trailer.

5:02pm- Rocket cows hack the stream
5:03pm- Basket goes down
5:37pm- Basket goes up
5:44pm- Basket goes down
6:32pm- LR11000 picks up a deluge pipe
6:51pm- Grover swings out of the way
6:57pm- LR11000 Starts swinging deluge pipe over. Straight pipe with a curve on the end closest to the OLM.
6:59pm- Starts lowering pipe to the back left side OLM
7:47pm- Small crane lifts a short piece of pipe next to the bigger piece the LR11000 lifted over
7:51pm- Short piece swung back away
9:00pm- Looks like some work on the lid for the cryo pipe vault. Some people going in and out of the ring around the OLM. They’re hiding what we really want to see behind the tarps though.
9:15pm- LR11000 moves to pick up Y pipe
9:41pm- Lifting straps connected to the crane
9:56pm- Y pipe lifted
9:58pm- Swung around the OLM
10:06pm- Lowered to just above the OLM
10:08pm- Guide rope got stuck on smaller crane. Had to go back up.
10:09pm- Going back down
10:12pm- Sat on the ground right outside the pit.
10:14pm- Lifted Up slightly and rotated
10:15pm- Lowered into the pit
10:25pm- For those wanting to keep track, In Ryan’s renders, we’ve seen the bottom pipe that goes to the middle manifold and the Y section that goes over it lifted in so far. There should be 2 short pieces next to connect the Y to the other 2 manifolds.
(This gets synced)
Much lifting and lowering and all sorts of craney stuff, but it’s believed that all the manifolds are in place by now. A nice Imgur picture of a manifold being craned.
This is the finest FAQ in the fediverse. I come back to it, just to appreciate just how much data you fit in it, so easily accessible and concise for the experienced and inexperienced alike. It makes up for so many poorly written, ugly, inhuman FAQs across the years.

Heyhey, Decronym for Lemmy, that must be a good sign!
What about it!? @FelixSchlang tweet from 3:03 PM - Jun 29, 2023:
It happened!!!
SpaceX opened the wall to the inventory tent and revealed one of the water deluge plates to us up close and countless other things in there!
High res pictures for supporters on all platforms coming soon!
In a reply, they said it looks to be upside down.
In The Other Place, u/warp99 wrote,
Looks like the segments are around 400mm thick and constructed from 40mm (38mm=1.5"?) steel plate The overall shape is a hexagon about 10m across the flats with each corner notched out.
They also speculated on how to weld the edges together: maybe put them on a stand above the final location, weld them from above and below, attach cranes and remove the stand, lower into place.
Starship Gazer (as seen on Nitter) had more pictures.
“SpaceX launched the most powerful rocket ever built. Its impact is still felt in this Texas community”, a CNN article dated Friday, 7 July 2023.
Musk has repeatedly said he’d like to try to launch Starship again as soon as this summer, but the FAA said in a statement to CNN that SpaceX has yet to take public safety actions or submit a mishap report with corrective actions for FAA review and approval.
This thread is no longer being updated, and has been replaced by:
Starship Development Thread #47
Elon thinks the next launch will be in 6 to 8 weeks
8 weeks to resume testing on the OLM perhaps, but there will be a lot of new stuff to test before launch
Ship 25 completed a flight-like chill and spin of the Raptor engine pumps, stopping just before engine ignition. As a result of the test, cryogenic liquid oxygen formed a visible cloud beneath the ship. This checked out vital systems in advance of the upcoming static fire.
This is great thank you, I started following spacex Reddit in the echologic (was that his name?) Days, but the sub got a bit, I dunno, it started to lack a certain something. Just got too big maybe.
I’m happy to see this here! Thanks for starting it, sorry for the off topic 😂
Looks like the Ship Quick-Disconnect is back!
