Video: Change of command aboard International Space Station

SpaceX was already tasked with returning NASA astronauts Butch Wilmore and Suni Williams as part of the Crew-9 mission. That departure was delayed by NASA due to unresolved issues with the fifth Crew Dragon capsule that will launch the Crew-10 flight.

SpaceX technicians offloaded a Dragon cargo capsule from its recovery ship Thursday after returning the thrice-flown supply freighter to the Port of Los Angeles, marking the final planned return of a Dragon spacecraft to the West Coast.

SpaceX ran through countdown and fueling procedures with a Falcon 9 rocket at NASA’s Kennedy Space Center in Florida on Sunday, culminating in ignition of the booster’s nine first stage Merlin engines in a customary check of the launcher’s readiness before liftoff Thursday with a Dragon supply ship for the International Space Station.
