Photos: Delta 4 lights up the sky for night owl launch

A United Launch Alliance Delta 4-Heavy rocket climbed into orbit Monday from a military base northwest of Los Angeles, delivering to space a classified U.S. government spy satellite as large as a school bus and leaving just three Delta rockets left to fly before retirement.

SpaceX has launched a Falcon 9 rocket with a previously-flown first stage booster carrying the SES 12 communications satellite, an all-electric, multi-band video and data relay platform to serve the Asia-Pacific region. Liftoff from Cape Canaveral occurred at 12:45 a.m. EDT (0445 GMT), and SpaceX did not plan to recover the first stage.

A United Launch Alliance Atlas 5 rocket put on a display of power, sound and light Friday evening at Vandenberg Air Force Base in launching a clandestine national security payload, then successfully debuted a new upper stage engine as it flew over the horizon.
