Video: Delta 4 launch highlights

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.

United Launch Alliance technicians were allowed to return to the Atlas 5 pad Tuesday as firefighters continued to wage air and ground campaigns against the wildfire burning at Vandenberg Air Force Base in California.

SpaceX test-fired a Falcon 9 rocket for the second time Saturday after replacing a valve following an earlier static fire test Wednesday. The move has postponed the Falcon 9 rocket’s launch with the Amos 17 commercial communications satellite to no earlier than Tuesday.
