American military strategic defense satellite.

AKA: Shuttle Pallet Satellite. Status: Operational 1983. First Launch: 1983-06-18. Last Launch: 1997-08-07. Number: 6 . Gross mass: 3,230 kg (7,120 lb).

The SPAS (Shuttle Pallet Satellite) satellite was a reusable free-flying vehicle built by Messerschmitt-Bolkow-Blohm, which could be deployed and then retrieved by the US Space Shuttle's Remote Manipulator System arm.

The original SPAS, with materials processing and SDI-related sensor payloads, was used on several missions (STS-7, STS-11, STS-39). An experiment-carrying truss (USS) based on the original SPAS structure (but without the avionics and attitude control) was flown on the Spacelab D-1 and D-2 missions.

ORFEUS-SPAS, the Orbiting and Retrievable Far and Extreme UV Spectrometer, was a German astronomical satellite. It was be deployed by the shuttle remote manipulating system arm and retrieved after six days of free flight. The main instrument was a 1 meter telescope with extreme ultraviolet (400-1150 Angstroms) and far ultraviolet (900-1250 Angstrom) spectrometers of high spectral resolution. Also carried was the Princeton Interstellar Medium Absorption Profile Spectrograph which studied the fine structure of ultraviolet absorption lines in stellar spectra caused by interstellar gas. The ORFEUS program was managed by the German space agency.

CRISTA-SPAS, equipped for observation of the earth's atmosphere, was flown on two missions.

Subtopics

STS-66 Carried Atlas-3 laboratory; deployed and retrieved CRISTA-SPAS.

STS-85 Deployed and retrieved the CRISTA-SPAS-2 (the Cryogenic Infrared Spectrometers and Telescopes for the Atmosphere-Shuttle Pallet Satellite-2) designed to study Earth's middle atmosphere.
