Employees of Daimler-Benz Aerospace in the Multi-Payload Processing Facility install insulation on the Cryogenic Infrared Spectro-meters and Telescopes for the Atmosphere-Shuttle Pallet Satellite-2 (CRISTA-SPAS-2) payload for the STS-85 mission. The CRISTA is a system of three telescopes and four spectrometers to measure infrared radiation emitted by the Earth’s middle atmosphere. During the 11- day mission, the CRISTA-SPAS-2 free-flying satellite will be deployed from the Space Shuttle Discovery and retrieved later in the flight. Also onboard the satellite will be the Middle Atmosphere High Resolution Spectrograph Investigation (MAHRSI) to measure ultraviolet radiation emitted and scattered by the Earth’s atmosphere
