SpaceX closes out year with successful GPS satellite launch
A new era in GPS navigation launched Sunday, when a SpaceX Falcon 9 rocket climbed into orbit with a Lockheed Martin-built satellite designed to beam higher-power positioning, navigation and timing signals around the world, providing military and civilian users with more accurate data that is more resistant to growing jamming threats.
Air Force requirements will keep SpaceX from landing Falcon 9 booster after GPS launch
The demands of launching the first in an upgraded line of U.S. Air Force GPS navigation satellites, including a late load of extra fuel for the spacecraft and a military policy of reserving fuel to eliminate space junk, will keep SpaceX from recovering the first stage of its Falcon 9 rocket following liftoff Thursday from Cape Canaveral, according to mission managers.
