Near-infrared spectral mapping of Titan's mountains and channels

Sotin, Christophe; Barnes, Jason W.; Rodriguez, Sebastien +17 more

We investigate the spectral reflectance properties of channels and mountain ranges on Titan using data from Cassini's Visual and Infrared Mapping Spectrometer (VIMS) obtained during the T9 encounter (26 December 2005). We identify the location of channels and mountains using synthetic aperture radar maps obtained from Cassini's RADAR instrument du…

Predictions of the electrical conductivity and charging of the aerosols in Titan's nighttime atmosphere

Tripathi, S.; Whitten, R. C.; Borucki, W. J.

The electrical conductivity and electrical charge on Titan's atmosphere are computed for altitudes between 0 and 400 km on the nightside for which the main source of ionization is galactic cosmic rays (GCR). Unlike the dayside, electrical charging of the aerosol particles at night is not only negative but also time-dependent. Hence a time-dependen…

Modeling quasi-specular scattering from the surface of Titan

Tyler, G. Leonard; Sultan-Salem, Ahmed K.

The Cassini spacecraft obtained several scattering observations of the surface of Titan. Four data sets, TA-Inbound, TA-Outbound, T3-Outbound, and T8-Inbound, include scatterometer data for small angles of incidence. Analysis of these data sets provides an example use of a new generalized fractal-based quasi-specular scattering law that gives the …
