Video: Missile alert satellite launches atop Atlas 5

Up to 24 launches are planned from Cape Canaveral in 2015, thanks to jam-packed manifests for SpaceX and United Launch Alliance to send up satellites for the U.S. military, NASA and commercial telecom operators.

A United Launch Alliance Atlas 5 rocket lifted off Friday from Vandenberg Air Force Base in California with a classified payload for the National Reconnaissance Office. Launch occurred at 7:19 p.m. PST (10:19 p.m. EST; 0319 GMT).

SpaceX chief executive Elon Musk released the first images of his company’s Falcon Heavy rocket Wednesday, showing the massive triple-core booster almost fully assembled inside its hangar at the Kennedy Space Center’s pad 39A, where it is scheduled to lift off some time in January.
