The Cryogenic Infrared Spectrometers and Telescopes for the Atmosphere-Shuttle Pallet Satellite-2 (CRISTA-SPAS-2) payload for the STS-85 mission are hoisted for installation into a payload canister in the Multi-Payload Processing Facility (MPPF). There the payload will join the Technology Applications and Science-1 (TAS) payload prior to the trip to Launch Pad 39A. Once there, both will be installed into the payload bay of the Space Shuttle Discovery in preparation for the STS-85 mission. CRISTA is a system of three telescopes and four spectrometers to measure infrared radiation emitted by Earth's middle atmosphere. During the 11-day mission, the CRISTA-SPAS-2 free-flying satellite will be deployed from Discovery and retrieved later in the flight.
