Payload Assist Module (PAM)

A solid motor developed for the Space Shuttle program. Its purpose is to lift a satellite from the parking orbit into which it is placed by the Shuttle to a higher, designated orbit from which the spacecraft will actually operate. A special PAM, known as PAM-D, was adapted for use with Delta launch vehicles.
