The U.S. military’s next GPS navigation satellite moved to a SpaceX launch facility late Thursday at Cape Canaveral, ready for attachment with a Falcon 9 rocket for liftoff June 30 to take the place of an aging GPS spacecraft launched from Florida’s Space Coast more than 20 years ago.

A problem with a U.S. Air Force tracking radar kept a Falcon 9 rocket crowned with a NOAA space weather observatory grounded Sunday, forcing a long-delayed mission to stay on Earth an extra day.
