Live coverage: Space station crew safely returns to Earth

SpaceX launched a reduced two-man crew on a flight to the International Space Station Saturday, along with supplies and a pair of empty seats for two Starliner astronauts waiting to hitch a ride home in February after an unexpected eight-and-a-half-month stay in orbit.

These are artist’s concepts and press conference briefing slides from the United Launch Alliance unveiling of its new Vulcan rocket to debut in 2019.

Three veteran space fliers rode a Soyuz rocket into orbit Wednesday from the Baikonur Cosmodrome in Kazakhstan, heading to the International Space Station for a five-month stay.
