Paper Abstract

The Cassini spacecraft will carry eighteen scientific instruments to Saturn. After it is inserted into Saturn's orbit, it will separate into a Saturn Orbiter and an atmospheric probe, called Huygens, which will descend to the surface of Titan. The Orbiter will orbit the planet for four years, making close flybys of five satellites, including multiple flybys of Titan. Orbiter instruments are body- mounted; the spacecraft must be turned to point some of them toward objects of interest. Optical instruments provide imagery and spectrometry. Radar supplied imaging, altimetry, and radiometry. Radio links contribute information about intervening material and gravity fields. Other instruments measure electromagnetic fields and the properties of plasma, energetic particles, and dust particles. The Probe is spin- stabilized. It returns data via S-band link to the Orbiter. The Probe's six instruments include sensors to determine atmospheric physical properties and composition. Radiometric and optical sensors will provide data on thermal balance and obtain images of Titan's atmosphere and surface. Doppler measurements between Probe and Orbiter will provide wind profiles. Surface sensors will measure impact acceleration, thermal and electrical properties, and, if the surface is liquid, density and refractive index.
