Live coverage: Kennedy Space Center to reopen Friday

SpaceX’s third Falcon Heavy rocket took off from the Kennedy Space Center in a predawn launch Tuesday, delivering two dozen research and weather observation spacecraft into orbit on a marathon three-and-a-half mission for the U.S. Air Force. The mission included the successful landing of the Falcon Heavy’s two side boosters back at Cape Canaveral, and a SpaceX recovery boat netted part of the rocket’s payload fairing for the first time.

A review team studying software glitches and other miscues that cropped up during an unpiloted test flight of Boeing’s CST-100 crew capsule last December has made some 60 recommendations to make sure all the known shortcomings are addressed before the spacecraft is cleared for another flight, NASA managers said Friday.

Held down by heavy-duty restraints, a Falcon 9 rocket fired up its nine Merlin engines for more than three seconds Thursday evening in a key readiness test before launching with a commercial television broadcast satellite next week.
