A solid-fueled Minotaur 4 rocket lifted off early Saturday from Cape Canaveral with a U.S. military payload designed to monitor satellite traffic in geosynchronous orbit.

Receiving a boost from a modified decades-old Peacekeeper missile originally built for nuclear war, a U.S. military space surveillance satellite streaked into space early Saturday from Cape Canaveral to help the Air Force track threats and debris in orbit.

A U.S. military satellite awaiting launch Friday night from Cape Canaveral is small enough to fit on a coffee table, but it will punch above its weight, scanning a region more than 20,000 miles above Earth to catalog spacecraft movements and space junk.
