Live coverage: Atlas 5 blasts off with Navy satellite

Rocket Lab’s Electron rocket, a commercially-developed light-class booster, lifted off at 1:33 a.m. EST (0633 GMT) Sunday, carrying 13 CubeSats into orbit under contract to NASA.

The 8-million-pound mobile service tower is retracted from around the Atlas 5 rocket, revealing the 189-foot-tall vehicle for liftoff from Vandenberg Air Force Base, California, carrying the commercial WorldView 4 Earth-imaging satellite.

Rainy weather at the California launch site is forecast to put a damper on plans to fly an Atlas 5 rocket on Thursday evening.
