Now, NASA is leaning into its uncertainty, and pushed the Ax-4 launch further, to June 22. "The change in a targeted launch date provides NASA time to continue evaluating space station operations after recent repair work in the aft (back) most segment of the International Space Station’s Zvezda service module," NASA Space Operations said on social media late Wednesday (June 17). The fixes to the leaky Falcon 9 first stage, on the other hand, are more definitive. That booster, designated B1094, is one of the newer ones in SpaceX's fleet, with only one previous launch under its belt. The rocket stage supported the Starlink 12-10 mission at the end of April, and apparently showed signs of a leak during that flight as well. SpaceX's vice president of build and flight reliability, Bill Gerstenmaier, told reporters during a June 9 press conference that technicians "discovered that we had not fully repaired the booster during refurbishment — or we didn't, actually, didn't find the leak and didn't get it corrected." But the repairs are complete now. SpaceX announced on June 12 that it has completed a new "wet dress rehearsal," or fueling test, with the rocket, and the launch vehicle is ready for the Ax-4 liftoff. Falcon 9 wet dress rehearsal complete. We’ll continue to work closely with @NASA and @Axiom_Space to determine the best launch opportunity for Dragon and the Ax-4 crew to the @Space_StationJune 12, 2025 Related stories:
