Photos: Atlas 5 rolls out for launch

A SpaceX Falcon 9 rocket successfully lifted off from Cape Canaveral at 10:29 a.m. EDT (1429 GMT) Wednesday with two Boeing-built communications payloads for Eutelsat and Asia Broadcast Satellite. A secondary objective to recover the first stage offshore in the Atlantic Ocean failed.

The launch from Cape Canaveral of a top secret spy satellite for the U.S. government was aborted at the last moment early Saturday as its United Launch Alliance Delta 4-Heavy rocket ignited three main engines, a dramatic cutoff of the countdown that will delay the mission by at least one week.

The launch of NASA’s Mars 2020 rover is less than a year away, and the steady pace of work inside the craft’s pristine assembly hall in California is keeping the mission on schedule for liftoff from Cape Canaveral next July, despite growing costs, according to mission managers.
