Return to the Saturnian System On the Cover: The Huygens probe descends through Titan's murky, brownish-orange atmosphere of nitrogen and carbon-based molecules, beaming its findings to the distant Cassini orbiter. The probe is equipped with a variety of scientific sensors to measure the physical properties of the moon's atmosphere; it also carries an imaging device to return pictures of Titan's possibly hydrocarbon-lake-dotted surface. The Cassini-Huygens mission is scheduled to reach the Saturn system in 2004.
