FAQ
- When next launch? IFT-3 is NET Feb 2024, and after completion of the IFT-2 mishap investigation. Candidate vehicles are Booster 10 and Ship 28.
- When previous launch? (IFT-2)? Booster 9 and Ship 25 launched on 2023-11-18.
- What was the result? Successful lift off with minimal pad damage. Successful booster operation with all engines to successful hot stage separation. Booster destroyed by AFTS after attempted boost-back. Ship fired all engines to near orbital speed then destroyed by AFTS. No re-entry attempt.
- Was IFT-2 a complete failure? No. As part of an iterative test programme, many milestones were achieved. Perfection is neither expected nor desired at this stage.

These vertical "methane" tanks never ultimately held methane, did they? Just water and (maybe?) some LN2 or LOx?
I recall something about Texas regulations stipulating that the tanks were too close together to safely hold fuel...
It's been asserted that they were used for water but I know of no evidence that they actually were.
Texas regulations require that the design for a methane storage system be done by a registered professional engineer certified to do methane storage systems in Texas and be submitted for approval before construction starts. Thus it's unlikely that they were "too close together". More likely they just didn't work right. Perhaps they had an excessive boiloff rate or too high a leakage rate.
Speculation: Perhaps they decided to build their own tanks because lead times for purchased tanks were too long. It worked out for LN2 and LOX.
I wonder why they have not recycled the suborbital tanks?
