Snapshots from Atlas 5 launch

The United Launch Alliance Atlas 5 rocket lifted off from Cape Canaveral at 7:05 p.m. EDT (2305 GMT) today to send NASA’s OSIRIS-REx spacecraft on a seven-year, 4.4-billion-mile mission to rendezvous with Asteroid Bennu and bring a sample of the primordial object back to Earth.

A United Launch Alliance Atlas 5 rocket is set to roll to its launch pad Wednesday at Cape Canaveral, a day before liftoff with a new-generation NOAA weather satellite. The launch of a SpaceX Falcon 9 rocket with a Spanish communications satellite is expected to be shuffled after the Atlas 5 flight in a rapid-fire launch sequence at the Florida spaceport this week.

The first of up to seven United Launch Alliance missions lifted off Jan. 19 from Vandenberg Air Force Base in California, where a Delta 4-Heavy launcher fired into orbit with 2.1 million pounds of thrust from three hydrogen-fueled RS-68A main engines with a U.S. government spy satellite.
