Video: Change of command aboard International Space Station

As expected, NASA announced Wednesday that the first unpiloted test flight of a SpaceX Falcon 9 rocket and a Crew Dragon astronaut ferry ship has slipped from later this month to March 2. The first unpiloted flight of Boeing’s Starliner capsule is now targeted for the April timeframe.

Astronauts Doug Hurley and Bob Behnken undocked from the International Space Station Saturday aboard a Crew Dragon capsule, heading for a parachute-assisted splashdown Sunday in the Gulf of Mexico to wrap up a 64-day test flight of SpaceX’s commercial human-rated spaceship.

The 15th resupply mission to the International Space Station by a Cygnus cargo freighter lifted off at 12:36 p.m. EST (1736 GMT) Saturday aboard an Antares rocket from Wallops Island, Virginia. The Northrop Grumman-owned spacecraft is carrying more than 8,000 pounds of experiments and provisions for the space station and its seven-person crew. Capture by the station’s robotic arm occurred at 4:38 a.m. EST (0938 GMT) Monday.
