Live coverage: SpaceX cargo ship arrives at space station

Carrying more science research gear to the International Space Station than ever launched before by U.S. commercial logistics vehicles, the next Orbital ATK Cygnus freighter takes flight Tuesday.

A United Launch Alliance Atlas 5 rocket is set to carry Boeing’s Starliner crew capsule into space on an unpiloted test flight to the International Space Station. This timeline shows the major mission events planned from liftoff through Starliner’s orbital insertion burn about 31 minutes after launch.

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.
