Touching down after 340 days in orbit, astronaut Scott Kelly and cosmonaut Mikhail Kornienko have returned to Earth from the International Space Station aboard a Soyuz crew capsule commanded by Sergey Volkov. Landing in Kazakhstan occurred at 0426 GMT Wednesday (11:26 p.m. EST Tuesday).

Flight controllers at NASA’s mission control center in Houston have completed the robotic swap out of a failed power distribution unit outside the International Space Station, clearing a hurdle ahead of Friday’s predawn launch from Cape Canaveral of a SpaceX supply ship.

A Soyuz rocket climbed away from a historic launch pad at the Baikonur Cosmodrome in Kazakhstan on Friday with three new crew members heading for the International Space Station.
