Surface albedo spectral properties of geologically interesting areas on Titan

Le Mouélic, S.; Rodriguez, S.; Sotin, C. +13 more

We investigate the nature and possible formation processes of three areas on Titan's surface which have been suggested as geologically interesting: Hotei Regio, Tui Regio, and Sotra Patera. We also reanalyze the spectral characteristics of the Huygens Landing Site. We apply a statistical Principal Component Analysis (PCA) and a radiative transfer …

Insights into Titan's geology and hydrology based on enhanced image processing of Cassini RADAR data

Lucas, Antoine; Aharonson, Oded; Hayes, Alexander G. +3 more

The Cassini Synthetic Aperture Radar has been acquiring images of Titan's surface since October 2004. To date, 59% of Titan's surface has been imaged by radar, with significant regions imaged more than once. Radar data suffer from speckle noise hindering interpretation of small-scale features and comparison of reimaged regions for change detection…

Predicting the characteristics of thunder on Titan: A framework to assess the detectability of lightning by acoustic sensing

Petculescu, Andi; Kruse, Roland

The search for lightning is an important item on the agenda for the future exploration of Titan. Thunder, as a direct lightning signature, can be used, together with electromagnetic signals, to corroborate and quantify lightning. Using Cassini-Huygens data and model predictions, the main characteristics of thunder produced by a potential 20 km clo…
