CAPE CANAVERAL, Fla., Dec. 10, 2007 -- A United Launch Alliance Atlas V rocket successfully launched a National Reconnaissance Office (NRO) payload at 5:05 p.m., EST, today from Space Launch Complex 41. This launch marks the fourth Atlas V EELV mission this year and the 12th ULA mission in 2007.

"ULA is proud to have played a critical role for this important NRO mission, ensuring that our nation has the technology and spaceborne assets needed to acquire intelligence worldwide," said Jim Sponnick, ULA vice president of Atlas programs. "Close teamwork with the NRO Office of Space Launch, the U.S. Air Force Launch and Range Systems Wing and the 45th Space Wing at Cape Canaveral made today's successful mission possible."
