The Space Test Program is a Department of Defense activity under executive management of the Air Force, created to provide spaceflights for DOD experiments not authorized their own means of spaceflight. This regulation prescribes the policies, procedures, and responsibilities for STP management. It provides potential sponsors,experimenters, and space craft designers with the information needed to prepare and submit spaceflight requests, and defines the relationship between sponsors, experimenters, and the STP management. It also describes the procedures followed in ranking STP experiments, selecting experiments to be included in a space mission, developing payloads, and managing payloads once they are defined.
