​SpaceX's Falcon 9 launches a mysterious mission called RRT-1 for the U.S. Space Force from Florida's Cape Canaveral Space Force Station Space Launch Complex 40.

The payload is suspected to be a third-generation Global Positioning System (GPS) satellite manufactured by Lockheed Martin, though limited information is available, and neither SpaceX nor the mission’s customer divulge what the payload was.
