Paper Abstract

For the infrared astronomy and earth atmosphere survey helium-cooled telescope and instruments are used since over 15 years. As a national program MBB (now DASA) had developed the GIRL (German Infrared Laboratory) - cryosystem from 1977 to 1985. Bases on the experience from there, the 'Infrared Background Signature Survey' (IBSS) -sensor was built, which flew successfully on Space Shuttle (STS39) in May 1991. Based on GIRL and IBSS DASA built the Payload Module (PLM) for the 'Infrared Space Observatory' (ISO) under ESA-contract. The basic designs of the GIRL-, IBSS-, and ISO-cryostats are described. Besides essential IBSS- flight data, important functional aspects of space cryostats are illustrated at the example of ISO. The flight hardware acceptance status of the ISO-PLM, which shall be launched for its 18-months IR-astronomy mission on an Ariane 4 - launcher in September 1995, is described together with important hardware elements and the total PLM.
