The Exploration and Mapping of Saturn’s Moon Titan
Saturn’s moon Titan is the most Earth-like world in the Outer Solar System. Just like Earth, Titan has a thick nitrogen atmosphere that supports an active weather cycle underneath Titan’s opaque organic haze layers. The Cassini spacecraft discovered that underneath Titan’s haze layers are familiar features like rivers, lakes, seas, dunes, plateaus, canyons, and mountains. But unlike Earth, frigid Titan’s rainfall is liquid methane, the lakes and seas are liquid hydrocarbons, the mountains are made of rock-hard water ice, and the dunes, plains, and plateaus are organic sediments. We are preparing a geomorphological map of Titan to identify and inventory the different terrains and features on Titan. We use the Cassini RADAR Synthetic Aperture Radar (SAR) swaths as a basemap and map using common GIS software packages such as ArcGIS (ESRI) or open-source QGIS.
