Live coverage: Kennedy Space Center to reopen Friday

The U.S. Air Force’s reusable Boeing-built X-37B spaceplane returned to Earth early Sunday with a touchdown at NASA’s Shuttle Landing Facility runway at the Kennedy Space Center in Florida, a few miles away from where it launched 780 days ago atop a SpaceX Falcon 9 rocket.

SpaceX is gearing up for the first commercial launch of its powerful Falcon Heavy rocket as soon as early April with a communications satellite for Arabsat, and the U.S. Air Force hopes the two side boosters from the Arabsat mission can be safely landed and reused for the military’s first Falcon Heavy mission this summer, an exercise officials said will help certify previously-flown hardware for future national security launches.

A malfunction during a drop test over Nevada last month for SpaceX’s Crew Dragon program has engineers re-examining the crew capsule’s parachutes, and Boeing has also encountered parachute failures during testing for its commercial crew capsule, a senior NASA official confirmed Wednesday.
