Live coverage: Kennedy Space Center to reopen Friday

A second unpiloted test flight of Boeing’s Starliner crew capsule — ordered after an initial demonstration mission fell short of reaching the International Space Station — is now scheduled for launch from Cape Canaveral in August or September, leaving little margin to conduct the spaceship’s first flight with astronauts before the end of the year.

One of SpaceX’s Falcon 9 rocket boosters made its second trip into space Friday, lofting a Bulgarian television broadcasting satellite from launch pad 39A at NASA’s Kennedy Space Center in Florida, then landing on a platform in the Atlantic Ocean. Liftoff occurred at 3:10 p.m. EDT (1910 GMT).

Loaded with supplies to keep the International Space Station’s crew fed, clothed and busy with new science projects, a Cygnus cargo vessel sped into orbit today atop an Atlas 5 rocket.
