Photos: More shots of Delta 4 liftoff

The United Launch Alliance Atlas 5 rocket with the NROL-52 spacecraft aboard moved to the launch pad this morning for liftoff Saturday to serve the national interest. Liftoff is scheduled for 3:31 a.m. EDT (0731 GMT).

This photo gallery includes a series of spectacular pictures of the launch of an Atlas 5 rocket Nov. 13 from Cape Canaveral with a classified payload for the National Reconnaissance Office.

After tropical weather passes through Florida to start the week, meteorologists say there is a 40 percent chance of acceptable conditions for the United Launch Alliance Delta 4-Heavy rocket to fly Thursday from Cape Canaveral with a reconnaissance satellite payload for the U.S. government.
