COVER A 170-km-wide region of Saturn's largest moon, Titan, revealed in synthetic aperture radar imaging from the Titan Radar Mapper instrument onboard the Cassini Orbiter. North is to the right. A complex and geologically young surface is revealed, with few impact craters but many features that may have been formed by cryovolcanism. See page 968.
