Video: Change of command aboard International Space Station

The Falcon 9 rocket set to launch the SpaceX’s Crew Dragon capsule on a test flight in February briefly ignited its Merlin main engines on pad 39A at NASA’s Kennedy Space Center in Florida on Thursday. The Crew Dragon test flight to the International Space Station is a precursor to the spaceship’s first mission with astronauts later this year.

Leaving crewmate Peggy Whitson behind in orbit for an extended mission, a Russian cosmonaut and his French co-pilot undocked from the International Space Station early Friday and plunged back to Earth, landing on the steppe of Kazakhstan to close out a 196-day mission.

Boeing’s Starliner crew capsule accomplished an early at White Sands Space Harbor in New Mexico at 7:58 a.m. EST (5:58 a.m. MST; 1258 GMT) Sunday to conclude an abbreviated two-day unpiloted test flight after a timing error on the spacecraft shortly after launch prevented it from linking up with the International Space Station as planned.
