Personnel from the 45th Operations Group, Detachment 3, simulate astronaut rescue and recovery operations, Dec 12, 2018, off the coast of Cape Canaveral Air Station, Fla. As the U.S. prepares to return to human spaceflight, Det. 3 in coordination with NASA and commercial partners, will play a direct role in rescue and recovery of astronauts because they are the only Department of Defense unit responsible for all aspects of human spaceflight recovery including planning of rescue tactics, real-world execution, and overall command and control of the human spaceflight mission.
