Abstract

The European Space Agency's ISO satellite is a liquid helium cooled space observatory for infrared astronomy. It will be launched for an 18 month mission in 1995 by the Ariane 4 rocket. The payload module contains a 60 cm telescope and 4 focal plane instruments covering the wavelength range 2.4 to 240 micrometers . During the first cold tests early in 1994, ISO's 2300 1 tank was partially filled with superfluid helium. The main purpose of this test was to check all the functions of the instruments and their compatibility in ISO's cryovacuum environment. In addition the straylight level caused by thermal emission of the cryostat's interior was measured by the focal plane instruments.
