FAQ
- When is the next Integrated Flight Test (IFT-2)? Booster 9 + Ship 25 launched Saturday, November 18 after slight delay.
- What was the result? Successful lift off with minimal pad damage. Successful booster operation with all engines to successful hot stage separation. Booster destroyed after attempted boost-back. Ship fired all engines to near orbital speed then lost. No re-entry attempt.
- Did IFT-2 Fail? No. As part of an iterative test programme, many milestones were achieved. Perfection is neither expected nor desired at this stage.
- Next launch? IFT-3 expected to be Booster 10, Ship 28 per a recent NSF Roundup. Probably no earlier than Feb 2024. Prerequisite IFT-2 mishap investigation.

The fate of S25:
- astroferg on Twitter managed to get a shot of the S25 nosecone after the FTS was triggered
- It is possible that this was what was observed reentering near Puerto Rico
- NOAA weather radar data showing the track of the debris cloud
FAA/SpaceX mishap investigation has been triggered. Given that the FTS seems to have worked, and there is minimal damage to the ground infrastructure, I'm hoping that this investigation will be shorter.
Scott Manley investigation report is already completed: Starship & Superheavy Become The Biggest Rocket In Space.... Before Exploding
- He speculates that B9 engine failure during boostback was due to either fuel slosh, fluid hammer, or a combination of both. It's unclear whether the booster FTS was triggered or whether the Booster RUD happened on its own.
- For S25, he notes that a puff of gas just after T+7 minutes coincides with a drop in the LOx gauge. This indicates an oxygen leak of some sort, which could have any number of causes.

Busy day at Starbase yesterday:
- Inspections of OLM, B9, and S25 continue
- Net was removed from beneath OLM
- Chopsticks raised to lifting position on S25
- "Dance floor" work platform lowered onto an SPMT and removed from under the OLM
- SPMT moves the raptor install stand from near hopper to near sub orbital pad A
- Welding observed on several of the OLM legs
IFT-2 slips to NET November 15th. Road closures for the 13th and 14th have been cancelled, and the Mexican NOTMAR has been updated.
Dear Moon officially slips to NET 2024 :)

Seems launch delayed til Saturday, works out specifically for me!
7 0 ReplyIndeed. Source: https://nitter.net/elonmusk/status/1725231694645461403#m
We need to replace a grid fin actuator, so launch is postponed to Saturday
Will replacing the actuator will require another destack, or will they be able to fix it in place?
4 0 ReplyPretty unlikely that they could fix it in a day if it required destack

Starbase activities (2023-11-21):
- Testing performed on SQD and chopsticks
- S29, S30, and S31 were shuffled in and out of the High Bay.
- Mystery structure rolled into the build site, possibly a new transport stand.
IFT-2:
- astroferg uploaded stabilized tracking video of S25's nose cone after FTS was triggered
- SpaceX has updated their IFT-2 page. Nothing too surprising. They verified that S25 FTS was triggered, but have not said the same for B9.

- S30 moved out of High Bay
- SPMTs then left for the Rocket Garden, possibly to retrieve S28.
- Close-up of S30 and overview of Starships in production.
- Mystery stand moved out of the build site.
- Starbase's cat is still around after IFT-2.
- Lifting squid was removed and reattached to S28.
Could make them faster, but engine production is not the limiting factor.
I’m very excited about the next-gen Raptor engine that is robust enough not to require a heat shield. Will also have more thrust, higher Isp and many other improvements.

New CSI Starbase video: Superheavy’s Massive Fire Suppression System Dramatically Increases Performance
Ringwatchers article: What Changed on Starship 25 & Booster 9?
Elon tweets:
- Four more Starships, the last of V1
- Version 2 of the ship holds more propellant, reduces dry mass and improves reliability
- Re: N1, importance of engine isolation: If an engine failure is isolated, then many engines greatly increases reliability (Starship only loses <3% of thrust). If not, then reliability is terrible. The difference is at least 2 orders of magnitude.
- Starship is intended to carry a lot of people on tens of thousands of flights, so needs to be extremely reliable over time. It will be.
- Re: CSI Starbase: Good video

IFT-3 NET 2024 as per u/space_rocket_builder (a claimed/suspected insider) in The Other Place:
Well… expect a launch sometime early 2024. Findings from the last flight have been positive so far so we are expecting a much shorter turnaround time this time but still have a lot of work to do for the next flight.

- Launched at 07:02 CT.
- Hot staging worked well, but B9
FTS was triggeredexperienced a RUD shortly into the boostback burn. - S25 continued on a nominal trajectory up until a few seconds before SECO, at which point signal was lost, likely due to FTS being triggered.
Starbase activities:
- A couple tanker trucks lined up to refuel the tank farm.
- Workers returned to the pad by 09:00, currently inspecting the launch site and collecting debris.
- Chopsticks lowered.
Edit: Unclear if B9 FTS was triggered or not.

- The hot stage ring transport stand and loadspreader moved back to the launch site, possibly indicating another destack.
- Rainy weather may have precluded additional activities.
SpaceX have announced that IFT-2 is now NET November 17th. Still no FAA launch license yet.
