After splashing down safely in a SpaceX Dragon spacecraft off the coast of Jacksonville, Florida early Monday morning, NASA’s SpaceX Crew-6 completed the agency’s sixth commercial crew rotation mission to the International Space Station.

The Crew-6 mission is part of NASA’s Commercial Crew Program, and its return to Earth follows on the launch of NASA’s SpaceX Crew-7, which docked to the station Aug. 27, beginning another long-duration science expedition.

The international crew of four spent 186 days in orbit.
