Video: Soyuz MS-01 leaves the space station for landing

Running nearly a month late because of work to repair a damaged cable, a Russian Soyuz spacecraft was primed for launch early Wednesday to carry two cosmonauts and a NASA astronaut to the International Space Station, boosting the lab’s crew back to six.

SpaceX is likely to land the first stage of the Falcon 9 rocket set for launch April 30 on a drone ship just off the coast of Cape Canaveral, not at the company’s onshore recovery site as originally planned, after a ground test of the company’s Crew Dragon capsule at the landing pad ended in an explosion Saturday.
