Live coverage: Delta 2 launches

A threatening layer of clouds stayed away from SpaceX’s launch pad at Vandenberg Air Force Base in California on Tuesday, allowing for clear viewing of a spectacular Falcon 9 launch carrying commercial and scientific satellites into polar orbit.

The United Launch Alliance Atlas 5 rocket lifted off Thursday night at 10:44 p.m. EDT (0244 GMT) with NASA’s four formation-flying MMS satellites.

After scrubbing a countdown Saturday to review sensor data, Rocket Lab launched its first mission of 2021 from New Zealand at 2:26 a.m. EST (0726 GMT) Wednesday. The company’s light-class Electron rocket carried a super-secret payload for OHB, a German-headquartered satellite manufacturer.
