Photos: Atlas 5 rolls out for launch

United Launch Alliance said Monday it did not submit a proposal in a competition to launch a U.S. Air Force GPS navigation satellite, apparently relinquishing the contract to rival SpaceX, the only other company certified to launch the mission.

With a 2-to-1 thrust-to-weight ratio, the million-pound United Launch Alliance Atlas 5 rocket unleashed two-million pounds of ground-shaking thrust to power away from its seaside launch complex at 2:13 p.m. EST (1913 GMT) Sunday with the EchoStar 19 satellite.
