Shumann resonances and electromagnetic transparence in the atmosphere of Titan

Molina-Cuberos, G. J.; Eichelberger, H. U.; Schwingenschuh, K. +6 more

Among the multiple questions that the CASSINI/HUYGENS mission tries to answer is the likelihood of electric discharges in Titan's atmosphere. The instruments ``Huygens Atmospheric Structure Instrument'' and ``Radio and Plasma Wave Science'' will probe the electromagnetic emissions during the Huygens descent and Cassini flybys, respectively. Althou…

Simulating Titan’s tropospheric circulation with the Portable University Model of the Atmosphere

Keller, H. U.; Grieger, B.; Rodin, A. V. +4 more

The Portable University Model of the Atmosphere (PUMA) is a general circulation model of intermediate complexity. In the model setup used herein, the dynamics is driven by restoration to a prescribed temperature field. Given an observed three-dimensional field of restoration temperatures, the feedback of aerosol distribution to the radiation schem…

Sicily 2002 balloon campaign: a test of the HASI instrument

Fulchignoni, M.; Colombatti, G.; Ferri, F. +9 more

A mock-up of the probe descending in the Titan atmosphere as part of the Huygens Cassini Mission was successfully launched and recovered on 30th May 2002 after a stratospheric balloon launch from the Italian Space Agency Base "Luigi Broglio" in Trapani, Sicily. To simulate the Huygens mission at Titan, the probe was lifted to an altitude of 32 km …

Some comments on the F ring-Prometheus-Pandora environment

Winter, O. C.; Giuliatti Winter, S. M.

The system formed by the F ring and two close satellites, Prometheus and Pandora, has been analysed since the time that Voyager visited the planet Saturn. During the ring plane crossing in 1995 the satellites were found in different positions as predicted by the Voyager data. Besides the mutual effects of Prometheus and Pandora, they are also dist…
