Photos: Pad cameras capture Atlas 5 launch

Taking advantage of available astronaut time, the International Space Station’s crew will cast off the commercial Orbital ATK Cygnus freighter on Sunday morning nearly six weeks ahead of schedule.

The Atlas 5 rocket emerges from the Vertical Integration Facility for rollout to Complex 41 at Cape Canaveral in preparation to launch GPS 2F-11 on Friday at 12:17 p.m. EDT.

A United Launch Alliance Atlas 5 rocket made its third trip to a Cape Canaveral launch pad Thursday, rolling into position for liftoff Friday afternoon with a classified payload for the U.S. government’s spy satellite agency.
