Live coverage: SpaceX launches 56 more Starlink internet satellites

United Launch Alliance called off the launch of a Delta 2 rocket from California’s Central Coast early Tuesday after boats ventured into a restricted safety exclusion zone and engineers ran out of time to resolve a technical problem on the launcher.

This is the launch highlights reel from United Launch Alliance of the Atlas 5 rocket carrying the fourth mission of the Air Force’s X-37B spaceplane.

Crowned with a European-built communications satellite designed to broadcast television over the Americas, a SpaceX Falcon 9 rocket with a previously-flown first stage booster lifted off Kennedy Space Center’s launch pad 39A Wednesday at 6:53 p.m. EDT (2253 GMT).
