Abstract

Infrared mapping spectrometry, a new remote sensing tool in which a scene is imaged simultaneously in hun-dreds of wavelengths, will be used on several approved planetary missions. A second-generation visible and infrared mapping spectrometer (VIMS) has been selected for both the Mars Observer and Comet Rendezvous Asteroid Flyby (CRAF) missions. The modular VIMS design can be adapted easily to the differing characteristics of several planetary missions planned through the end of the century. VIMS is a scanning spectrometer with a focal plane consisting of linear arrays of visible and infrared detectors, cooled by a radiative cooler. The foreoptics may be tailored to different missions, according to their field-of-view and resolution requirements. A wide-angle scan is implemented for Mars Observer, using a full-aperture scan mirror. A narrow-angle scan is achieved for the CRAF mission, using a scanning secondary mirror within a Cassegrain foreoptic. A significant on-board data processing capability has been designed to provide software flexibility, thus allowing for varying mission objectives and highly variable telecommunication data rates.
