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

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.

Final preparations began this weekend at NASA’s Stennis Space Center in Mississippi to load super-cold liquid hydrogen and liquid oxygen into the massive core stage of the Space Launch System heavy-lift rocket for the first time as soon as Monday.

Three days after high winds scrubbed a launch attempt Friday, Rocket Lab launched an Electron rocket with four satellites from New Zealand at 1212 GMT (8:12 a.m. EDT) Monday.
