Photos: Delta 4’s foggy launch

Rocket Lab’s Electron launcher delivered two all-weather radar Earth observation satellites into orbit for Capella Space Thursday night after liftoff from Wallops Island, Virginia, successfully completing the company’s second flight from the U.S. spaceport.

Rocket Lab’s next launch from New Zealand is set for no earlier than June 27 with a bundle of spacecraft including a commercial Earth-observing microsatellite for BlackSky, two CubeSats for U.S. Special Operations Command, a pair of tiny prototype data relay nodes for Swarm Technologies, a student-built payload from Australia, and a satellite whose identity and owner remain a secret.

Juggling simultaneous launch campaigns on both coasts, a team of SpaceX engineers put a Falcon 9 rocket through a customary countdown rehearsal and hold-down firing Tuesday at Vandenberg Air Force Base in California ahead of a scheduled liftoff Sunday.
