The Air Force has added a ninth navigation satellite to an orbiting network capable of pinpointing U.S. military units anywhere in the world to within 50 feet.

A Delta rocket blasted off with the $65 million Navstar satellite at 5:56 p.m. Monday. About 25 minutes later, the satellite separated from the booster as planned and settled in an orbit 12,532 miles above Earth."Everything appears to have gone well," said Air Force Lt. Col. Jim Jannette. Two launch attempts late last week were delayed by bad weather.
