Delta 4 Heavy Rocket Lifts Spy Satellite

(Vandenburg Air Force Base, California)

The largest rocket in America launched a spy satellite Wednesday from California.

Taking off from Vandenburg Air Force Base, the Delta IV-Heavy rocket lifted off just after 2pm Wednesday afternoon. The highly secretive payload, known as NROL-65, is believed to be the most advanced spy satellite ever launched.

This is a big deal from an intelligence-gathering standpoint.
