The Air Force has launched a rocket carrying a top-secret satellite for the United States.
The unmanned Atlas V rocket rose from its seaside Cape Canaveral launch pad Wednesday morning. On board was a satellite belonging to the National Reconnaissance Office.
The office declined for security reasons to provide any details of the satellite, its mission or even whether it reached orbit.
A launch attempt Monday was foiled by a problem with the environmental control system at the pad. The rocket had to be removed temporarily from the pad, in order to fix the problem.
