24 Saturn ’ s Exploration Beyond Cassini - Huygens
For its beautiful rings, active atmosphere and mysterious magnetic field, Saturn is a fascinating planet. It also holds some of the keys to understanding the formation of our Solar System and the evolution of giant planets in general. While the exploration by the Cassini-Huygens mission has led to great advances in our understanding of the planet and its moons, it has left us with puzzling ques...
متن کاملMagnetospheric and Plasma Science with Cassini-huygens
Magnetospheric and plasma science studies at Saturn offer a unique opportunity to explore in-depth two types of magnetospheres. These are an ‘induced’ magnetosphere generated by the interaction of Titan with the surrounding plasma flow and Saturn’s ‘intrinsic’ magnetosphere, the magnetic cavity Saturn’s planetary magnetic field creates inside the solar wind flow. These two objects will be explo...
متن کاملTemperature variations in Titan’s upper atmosphere: Impact on Cassini/Huygens
Temperature variations of Titan’s upper atmosphere due to the plasma interaction of the satellite with Saturn’s magnetosphere and Titan’s high altitude monomer haze particles can imply an offset of up to ±30 K from currently estimated model profiles. We incorporated these temperature uncertainties as an offset into the recently published Vervack et al. (2004) (Icarus, Vol. 170, 91–112) engineer...
متن کاملAnalytical pyrolysis experiments of Titan aerosol analogues in preparation for the Cassini Huygens mission.
Comparative pyrolysis mass spectrometric data of Titan aerosol analogues, called "tholins", are presented. The Titan tholins were produced in the laboratory at Cornell by irradiation of simulated Titan atmospheres with high energy electrons in plasma discharge. Mass-spectrometry measurements were performed at FOM of the solid phase of various tholins by Curie-point pyrolysis Gas-Chromatograph...
متن کاملPhotochemical Enrichment of Deuterium in Titan’s Atmosphere: New Insights from Cassini-huygens
Cassini-Huygens data are used to re-examine the potential sources of the D/H enhancement over solar, measured in methane, in Titan’s atmosphere. Assuming that the system is closed with respect to carbon, the use of constraints from the Huygens probe for the determination of the current mass of atmospheric methane and the most up-to-date determination of D/H from Cassini/CIRS infrared spectra al...
