Video: Weather causes Atlas 5 countdown hold

A United Launch Alliance Delta 4-Heavy rocket lifted off from Vandenberg Air Force Base in California at 1:47 p.m. PDT (4:47 p.m. EDT; 2047 GMT) Monday with a classified satellite for the National Reconnaissance Office, the U.S. government’s spy satellite agency.

Four clandestine payloads for the National Reconnaissance Office are awaiting liftoff Wednesday from Wallops Island, Virginia, on a Minotaur 4 rocket powered by Cold War-era missile stages stored for more than 30 years until their conversion into a satellite launcher.

United Launch Alliance revealed its visionary approach to space exploration in the next decade courtesy of the Vulcan rocket’s new, long-duration upper stage that can be fitted with as many as four engines to perform cargo resupply and astronaut transportation to far-flung destinations.
