The ISO was flown on the Space Shuttle as part of the Atmospheric Laboratory for Applications and Science (ATLAS 1) and on Spacelab 1. The purpose of the ISO on ATLAS 1 was to concentrate on specific scientific issues that were raised with the ISO measurements taken on Spacelab 1. The instrument is composed of five identical spectrometers, each of which is restricted to a given spectral range in the 30- to 1300-nm region. Each module is an imaging spectrometer with coincident 0.65 x 0.01 deg fields of view. Imaging is obtained along the length of the observational field by use of an intensified-solid state array detector developed especially for the ISO. The wavelength resolution varies between 0.2 and 0.6 nm over the spectral range. A scan mirror is used to direct the spectrometer at selected regions of the atmosphere. The experiment also had a solar pointing mode in which observations of the extreme ultraviolet (30 - 125 nm) spectral region of the Sun were made. A dedicated instrument microcomputer located seperately on the instrument pallet was used to interact directly with the ATLAS 1 computer providing a link between the instrument and scientists on the ground.
