Abstract

GIRL consists of a liquid helium cooled 50 cm telescope and four focal plane instruments dedicated to astronomical and aeronomical observations. These instruments, a detector array, a photometer/polarimeter, an Ebert-Fastie-spectrometer and a Michelson-Interferometer are under development. They make up an "infrared observatory" having high sensitivity and high spectral and spatial resolution. The full-size "thermal-model" of the GIRL cryostat has now been completed and is undergoing extensive tests. GIRL will be pointed by IPS. It is scheduled to fly on a Spacelab mission in 1986.
