SpaceX’s Xmas Sleigh for the Air Force delivered the goods just now.
Today’s launch of the GPS III upgrade satellite marks the beginning of a SpaceX contract to send national security payloads into orbit for the US government.
The solar panel arrays will unfold from the top and bottom, and that little rocket engine you see on the boxy satellite will take it up to a 20K Km orbit and help it stay there for a long time. Details: https://www.gps.gov/systems/gps/space/
