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.
