The flight readiness review for NASA’s SpaceX Crew-4 mission to the International Space Station has been completed and teams are continuing to take off at 5:26 a.m. EDT on Saturday, April 23, from the Kennedy Space Center launch complex 39A in Florida. The date adjustment provides time for mission teams to complete the finalization of the Crew-4 mission after the launch of Axiom Mission 1 on April 8 at the space station.

Steve Stitch, Manager, Commercial Crew Program at the Kennedy Space Center, participated in a flight readiness review for the SpaceX Crew-4 mission at the Florida Spaceport on April 15, 2022. International partners also participated. The heads of NASA and SpaceX missions held the FRR to confirm that the SpaceX Falcon 9 rocket and the Crew Dragon spacecraft were ready to be launched.

Mission teams continue to monitor operational schedules with ongoing space station activities, including upcoming spacewalks and the return of Ax-1 crew members. The weather forecast remains a monitoring element to ensure the safe recovery and launch of operations for the crew missions. The Crew-4 date also provides three consecutive backup boot options on Sunday, April 24, and Monday, April 25.
