Live coverage: Space station crew safely returns to Earth

A three-minute test flight Tuesday morning over Cape Canaveral will help ensure NASA’s Orion crew capsule — the vehicle being built to carry astronauts back to the moon — can safely escape from a catastrophic failure on launch.

The Falcon 9 booster for SpaceX’s next mission fired up briefly on a Cape Canaveral launch pad Sunday in a routine pre-flight test before a scheduled launch Friday night to kick off the final flight of the first version of the company’s Dragon cargo capsule to the International Space Station.

SpaceX test-fired a previously-flown Falcon 9 rocket Monday evening on pad 39A at NASA’s Kennedy Space Center in Florida, setting the stage for a launch later this week carrying the Japanese-built, Qatari-owned Es’hail 2 communications satellite to orbit.
