Photos: Atlas 5 rolls out for launch

NASA launch commentator George Diller called the Atlas 5 with Cygnus, his final liftoff as the voice of launch control before retirement next month. He has worked at the Kennedy Space Center for nearly four decades and served as the commentator for such memorable launches as Hubble, Cassini, Mars Pathfinder, the Spirit, Opportunity and Curiosity rovers and the final space shuttle mission.
