Video: Change of command aboard International Space Station

An unpiloted test flight of Boeing’s Starliner crew capsule to the International Space Station will be delayed from its previous target launch date of April 2 until at least May, after the arrivals of Russian Soyuz and SpaceX Crew Dragon ships bringing fresh crew members to the orbiting complex, NASA officials said Monday.

SpaceX’s Crew Dragon “Resilience” spacecraft and Falcon 9 rocket — stretching 215 feet long — are ready for rollout to pad 39A at NASA’s Kennedy Space Center in preparation for the launch of four astronauts Saturday night to the International Space Station.

A commercial Dragon cargo capsule will remain at the International Space Station until Saturday, three days later than previously planned due to high sea states observed by the SpaceX recovery team in the spaceship’s splashdown zone in the Pacific Ocean.
