Session 52 - First Results from the Infrared Space Observatory.
Oral session, Wednesday, June 12
ESA's Infrared Space Observatory (ISO) satellite was launched successfully by Ariane flight 80 in November 1995 into an elliptical 24-hour orbit. The satellite essentially consists of a large cryostat containing superfluid liquid helium to maintain the 60-cm aperture telescope, the scientific instruments and the optical baffles at temperatures between 2K and 8K. A pointing accuracy at the arc second level is provided by a three-axis- stabilisation system. ISO's instrument complement consists of four instruments, namely: an imaging photo-polarimeter (2.5--240\mum), a camera (2.5--17\mum), a short wavelength spectrometer (3--45\mum) and a long wavelength spectrometer (43--196\mum). ISO's Mission Operations Centre is located at Villafranca, Spain and ISO is used scientifically for the nearly 17 hours a day that it spends outside the Earth's radiation belts. Following completion of a highly successful commissioning and performance verification phase, ISO is now in its routine operations phase. An overview of the scientific mission, including details of the in-orbit performance of the spacecraft and plans for observing time, will be given.
