CAPE CANAVERAL. Fla. - The Air Force has launched a new spy satellite.
The Atlas rocket should have flown two weeks ago. But crucial radar-tracking equipment was damaged a day before the planned March 25 liftoff. An electrical short overheated the unit. Because repairs continue, the Air Force used backup radar to monitor Thursday afternoon's launch.
The radar accident also delayed a private SpaceX launch, now targeted for Monday.
SpaceX has a fresh load of supplies for the International Space Station. NASA is using private companies to keep the orbiting lab stocked.
