Live coverage: Three-man crew docks with space station

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.

NASA Administrator Jim Bridenstine says he is “fairly confident” that astronauts can fly to the International Space Station aboard SpaceX’s Crew Dragon spaceship at the end of May or early June, pending final parachute tests, data reviews and a training schedule that can escape major impacts from the coronavirus pandemic.

Targeting a resumption of Antares cargo launches to the International Space Station as soon as July, Orbital ATK plans to roll out an upgraded Antares rocket to a launch pad in Virginia this week for a 30-second firing of the booster’s new engines.
