Congressional Space Medal of Honor

The Congressional Space Medal of Honor was authorized by the United States Congress in 1969 to recognize "any astronaut who in the performance of his or her duties has distinguished himself or herself by exceptionally meritorious efforts and contributions to the welfare of the Nation and mankind". It is awarded by the president of the United States in Congress's name on recommendations from the administrator of the National Aeronautics and Space Administration. The award is a separate decoration from the Medal of Honor, which is a military award for extreme bravery and gallantry in combat.

While the Congressional Space Medal of Honor is a civilian award of the United States government, it is authorized as a non-military decoration for display on U.S. military uniforms because it is awarded by a federal agency. In such cases, the Congressional Space Medal of Honor is worn as a ribbon "immediately preceding the Prisoner of War Medal". DoD policy specifically prohibits wear of any non-military awards for valor or service, but the Congressional Space Medal of Honor only recognizes meritorious achievement, so it does not fall under this prohibition.
