Intensive Titan Exploration Begins

  author={Paul R. Mahaffy},
  pages={969 - 970}
The Cassini Orbiter spacecraft first skimmed through the tenuous upper atmosphere of Titan on 26 October 2004. This moon of Saturn is unique in our solar system, with a dense nitrogen atmosphere that is cold enough in places to rain methane, the feedstock for the atmospheric chemistry that produces hydrocarbons, nitrile compounds, and Titan's orange haze. The data returned from this flyby supply new information on the magnetic field and plasma environment around Titan, expose new facets of the… 

Titan observations by the Cassini Orbiter

Because Titan orbits a planet, it is officially a satellite. But it resembles a planet itself in some fascinating ways. Its size, for one thing: Titan is bigger than the planet Mercury. And it has an


Observations by the Visual Infrared Spectrometer instrument (VIMS) aboard the Cassini mission have indicated the possible presence of CO 2 ice on the surface on Titan, in areas which exhibit high

The direct simulation of acoustics on Earth, Mars, and Titan.

DSMC results at a variety of altitudes on Earth, Mars, and Titan including the details of nonlinearity, absorption, dispersion, and molecular relaxation in gas mixtures are given.

Structure of Titan's low altitude ionized layer from the Relaxation Probe onboard HUYGENS

Some of the secrets of the atmosphere of Titan have been unveiled by the Huygens Probe. The Permitivity Wave and Altimetry system detected a hidden ionosphere much below the main ionosphere, that

Astrophysics in 2005

We bring you, as usual, the Sun and Moon and stars, plus some galaxies and a new section on astrobiology. Some highlights are short (the newly identified class of gamma‐ray bursts, and the Deep

The relative cross section and kinetic energy distribution of dissociation processes of methane by electron impact

Electron-impact ionization and dissociation of methane (CH4) has been experimentally studied with a cold target recoil-ion momentum spectrometer. We report data for the formation of CHn+ (n = 0 ∼ 3)

Bulletin of the Geological Society of Greece

Dykes or small stocks of plagiogranitic rocL· occur below the extrusive sequence and in mutually interpenetrating association with the sheeted dyke complex of the Evros Ophiolite, NE Greece. They are



Touring the saturnian system: the atmospheres of titan and saturn

This report follows the presentation originally given in the ESA Phase A Study for the Cassini Huygens Mission. The combination of the Huygens atmospheric probe into Titan's atmosphere with the

Cassini Measurements of Cold Plasma in the Ionosphere of Titan

The Cassini Radio and Plasma Wave Science (RPWS) Langmuir probe (LP) sensor observed the cold plasma environment around Titan during the first two flybys. The data show that conditions in Saturn's

The Cassini UVIS Stellar Probe of the Titan Atmosphere

The Cassini Ultraviolet Imaging Spectrometer (UVIS) observed the extinction of photons from two stars by the atmosphere of Titan during the Titan flyby to determine the asymptotic kinetic temperature at the top of the atmosphere.

Energetic Neutral Atom Emissions from Titan Interaction with Saturn's Magnetosphere

The Cassini Magnetospheric Imaging Instrument (MIMI) observed the interaction of Saturn's largest moon, Titan, with Saturn's magnetosphere during two close flybys of Titan on 26 October and 13

Titan's Atmospheric Temperatures, Winds, and Composition

Early Cassini infrared observations of Titan show a stratopause at an altitude of 310 kilometers (and 186 kelvin at 15°S), and the concentrations of several stratospheric organic compounds are enhanced at mid- and high northern latitudes, and the strong zonal winds may inhibit mixing between these latitudes and the rest of Titan.

Cassini Radar Views the Surface of Titan

The Cassini Titan Radar Mapper imaged about 1% of Titan's surface at a resolution of ∼0.5 kilometer, and larger areas of the globe in lower resolution modes. The images reveal a complex surface, with

Ion Neutral Mass Spectrometer Results from the First Flyby of Titan

The Cassini Ion Neutral Mass Spectrometer (INMS) has obtained the first in situ composition measurements of the neutral densities of molecular nitrogen, methane, molecular hydrogen, argon, and a host

Titan's Magnetic Field Signature During the First Cassini Encounter

The magnetic field signature obtained by Cassini during its first close encounter with Titan on 26 October 2004 is presented and explained in terms of an advanced model. Titan was inside the

Galileo magnetometer measurements: a stronger case for a subsurface ocean at Europa.

The Galileo magnetometer measured changes in the magnetic field predicted if a current-carrying outer shell, such as a planet-scale liquid ocean, is present beneath the icy surface of Europa.
