Live coverage: Falcon 9 disintegrates after launch

SpaceX launched the X-37B military spaceplane onboard its Falcon Heavy rocket late Thursday night. Liftoff of the USSF-52 mission from NASA’s Kennedy Space Center occurred 8:07 p.m. EST (0107 UTC) on Thursday at the opening of a ten-minute launch window.

A SpaceX Falcon 9 launcher boosted a 4.7-ton military-grade communications satellite for SES and the Luxembourg government toward a perch 22,300 miles over the equator following a spectacular late afternoon liftoff Tuesday from Florida’s Space Coast, clearing the last mission off the launch company’s manifest before the long-awaited debut of the massive Falcon Heavy rocket.

SpaceX began erecting a new hangar at a former space shuttle launch pad in Florida last week, moving the historic facility closer to launching astronauts again.
