SpaceX originally planned to fly NASA’s Crew-5 crewed mission in early September, but the Falcon 9 rocket that was planned to be used for this mission was inspected and found to have problems with parts, and the launch was delayed for several weeks.

NASA and Roscosmos just agreed to use each other’s rockets.
