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…
Tectonic evolution of the eastern margin of the Thaumasia Plateau (Mars) as inferred from detailed structural mapping and analysis
Di Achille, G.; Ori, G. G.; Borraccini, F. +1 more
The eastern margin of the Thaumasia Plateau (EMTP) is characterized by a diversity of tectonic features, which recorded its complex, and still controversial, tectonic history. A detailed structural survey and analyses have been carried out in order to assess the kinematics and relative age of the main deformational events. Combining results from s…
The 2-µm spectroscopy of Huygens probe landing site on Titan with Very Large Telescope/Nasmyth Adaptive Optics System Near-Infrared Imager and Spectrograph
Drossart, P.; Gendron, E.; Rannou, P. +5 more
Several ground-based telescopes followed the event of the Huygens probe descent through Titan's atmosphere (14 January 2005). We used the Nasmyth Adaptive Optics System Near-Infrared Imager and Spectrograph (NACO) adaptive optics system at the UT-4 of the Very Large Telescope in Chile to perform both spectroscopic and imaging measurements of Titan…
Titan: Atmospheric and surface features as observed with Nasmyth Adaptive Optics System Near-Infrared Imager and Spectrograph at the time of the Huygens mission
Drossart, P.; Gendron, E.; Rannou, P. +5 more
At the time of the Huygens probe descent in Titan's atmosphere, on 14 January 2005, many ground-based telescopes were pointed toward Saturn's satellite. Here, we describe the data collected on 15 and 16 January with Nasmyth Adaptive Optics System Near-Infrared Imager and Spectrograph (NACO) at the Very Large Telescope. We acquired adaptive optics …
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 …
