Live coverage: Soyuz crew capsule departs station, lands in Kazakhstan

NASA has announced that veteran astronauts Joe Acaba and Ricky Arnold will launch on nearly six-month expeditions aboard the International Space Station starting in September and in March 2018, filling seats aboard Russian Soyuz spaceships recently acquired in a commercial arrangement with Boeing.

The mission will be the 14th time that a SpaceX Dragon spacecraft carries humans to the International Space Station. The mission launched on Friday, March 14, at 7:03 p.m. EDT (2303 UTC).

Two U.S. astronauts and a Russian cosmonaut, all spaceflight veterans, launched from Kazakhstan aboard a Soyuz booster Wednesday to begin a two-day pursuit of the International Space Station. The crew docked with the orbiting research complex Friday at 1940 GMT (3:40 p.m. EDT) to begin a five-month stay.
