Atthiswriting the Cassini spacecraft has ?redits engine and successfully inserted itself andits precious cargoof scienti?c instruments into orbit, the ?rst step of its exploration of the Saturnian system. The suspense is not over, however.

While terrestrial and HubbleSpace Telescope pictures have improvedgreatly over the years, they cannot match the resolution obtainable from orbitabout theplanet, and much of the data issimply unobtainablewithout direct insitu sensing. Volume 1 of this three volume set described the Cassini/Huygens mission, its scienti?c objectives and the Huygens probethat will soon enter theTitan at- sphere. Volume 2 described the insitu investigations on theorbiter. In this, the third and ?nal volume of the compendium, we describethe remote sensing inv- tigations: radioscience, radar, visibleandinfrared spectroscopy, thermalinfrared studies, ultraviolet spectroscopy and visible imagery.
