The National Aeronautics and Space Administration (NASA) is an independent agency of the US federal government responsible for the United States' civil space program and for research in aeronautics and space exploration. Like most U.S. government agencies, it is authorized to create awards and decorations for its employees, U.S. citizens and foreign nationals who have shown exceptional service to accomplishing the agency's goals.

The National Advisory Committee for Aeronautics (NACA) was a United States federal agency that was founded on March 3, 1915, to undertake, promote, and institutionalize aeronautical research. On October 1, 1958, the agency was dissolved and its assets and personnel were transferred to the newly created National Aeronautics and Space Administration (NASA). NACA created two awards in 1954 to recognize the distinguished/exceptional service of NACA employees. The medals are similar with the seal of NACA as the medal device and were approved by President Eisenhower in 1953. Only seven medals were awarded between 1954 and 1958 when NACA was transferred into NASA.
