Six experimental military satellites are circling the planet today after a late-night liftoff aboard a United Launch Alliance Atlas 5 rocket that blasted off from Cape Canaveral Air Force Station.
The stunning launch came at 10:10 p.m. -- or about 33 minutes late. A radio signal transmission problem and a sticky propulsion system valve prompted a delay in plans to launch at 9:37 p.m.
