Abstract

Since 2004 the Cassini spacecraft performed numerous targeted and non-targeted flybys at the major Saturnian satellites. During these flybys the Visual and Infrared Mapping Spectrometer (VIMS) onboard the Cassini spacecraft [1] detects the spectral properties of the satellites’ surfaces in the wavelength range from 0.35 to 5.1 μm with a spectral resolution that allows the mapping of the distribution of major surface compounds like H2O ice as well as discov-ery/identification of minor and/or trace compounds like CO2 as shown for several Saturnian satellites [2-6]. Mapping of these compounds revealed a distinct distribution of most of these surface compounds either related to geological surface features/processes or to weathering of the uppermost surface layer. In order to further our understanding of the Satutnian system we now performed an analysis of the spectral surface properties of Tethys in context of the surface geology as well as topography based on simultaneously ac-quired Cassini ISS images.

Abstract

The near-infrared reflectance of a 73,000 km2 area on Titan changed between July 2004 and March of 2006. The reflectance of the region (latitude 26S, longitude 78W) increased twofold between July 2004 and March-April 2005. It then returned to the July 2004 level by November 2005. By late December 2005 the reflectance had surged upward again to a new maximum. It then declined for the next three months. Detailed analyses indicate that the brightenings are a surface phenomenon, making these the first changes seen on Titan’s surface. The spectral differences between the region and its surroundings rule out the ices of H2O, CO2, and CH4 as possible causes. Remarkably, the change is spectrally consistent with the deposition and removal of ammoniated materials. NH3 has been proposed as a constituent of Titan’s interior but not its surface or atmosphere. This transitory NH3 spectral signature is consistent with occasional effusion events in which juvenile ammonia is brought to the surface. Its decomposition may feed nitrogen to the atmosphere. The size of the region suggests it may exceed the size of the largest active volcanic areas in the solar system.

Abstract

Since its insertion in Saturn’s environment in July 2004, the Cassini spacecraft has realized 20 Titan flybys. Three instruments can see through the haze: the ISS camera thanks to the infrared channel, the SAR (Synthetic Aperture Radar) and the Visual and Infrared Mapping Spectrometer (VIMS) [1]. During the first flyby, the VIMS showed its great potential to map and to characterize Titan’s surface despite scattering by haze particles and strong absorption of light by methane contained in the atmosphere [2]. Six infrared windows provide images of Titan’s surface and its spectral properties. At closest approach, the spatial resolution can be as good as 250 m/pixel, a resolution similar to that of the radar swaths. Because the VIMS capabilities were unexpected before the first observations, the VIMS had never been the prime instrument at closest approach before the T20 flyby that happened on 24 October 2006. This paper reports on the findings of this flyby.

Abstract

The surface of Titan has been revealed globally by the Cassini observations in the infrared and radar wavelength ranges as well as locally by the Huygens instruments. Sand seas, recently discovered lakes, distinct landscapes and dendritic erosion pattern indicate dynamic surface processes. During Cassini’s T20 flyby the Visible and Infrared Mapping Spectrometer (VIMS) [1] observed an extremely eroded area at 30° W, 7° S with resolution better than 350 m. Analyses of the drainage dynamics and comparison with the drainage systems at the Huygens landing site yield high discharge values of the associated channel systems and extreme runoff production rates of 10 to 50 cm/day. In addition, large sandur-like alluvial fans covering ten thousands of square kilometres are discovered at the boundary between high-standing bright and low-laying dark regions. To account for the estimated runoff production and widespread alluvial fan deposits of fine-grained material both frequent recurrence intervals and sudden release of areadependent large fluid volumes are required. Frequent equatorial storms with heavy rainfall of methane and related hydrocarbons might explain this catastrophic erosion. High-energy flow will cause mechanical weathering and large accumulations of sand in alluvial fans that is picked up by winds to form Titan’s vast equatorial sand seas and dune fields.

Abstract

Cassini studies of the surface of Titan are beginning to reveal its nature. In addition to hills, channels, and cobbles seen by the Huygens probe, the Visual and Infrared Mapping Spectrometer (VIMS) and RADAR instruments onboard the orbiter have seen sand dunes , channels , mountains [5, 6], and cryovolcanic candidates. Recently the RADAR team announced the discovery of possible lakes near Titan’s north pole.

Abstract

The Visual and Infrared Mapping Spectrometer (VIMS) aboard Cassini spacecraft allows us to characterize spectral properties of Titan’s surface through the atmosphere in seven narrow windows in the near infrared [1,2]. VIMS acquires images in 64*64 pixels cubes, with a 352 channels spectrum acquired for each pixel. The best resolution obtained so far was 1.4 km/pixel during T4 flyby (31 March 2005). A new observing strategy has been tested during T20 (25 October 2006) in order to observe at closest approach. It consists in acquiring a succession of single lines (using the first scanning mirror), the second dimension of the image being given by the evolution of the groundtrack of the satellite (instead of using the second scanning mirror). This new line mode provides a wider surface coverage than the nominal snapshot mode, and a spatial resolution of ~500 m/pixel at closest approach (which could go down to 250 m/pixel if the double resolution mode is used). We focus here on these new T20 VIMS data which crosses previous observations from the RADAR instrument recorded during the T3 flyby. The radar (in SAR mode) is mainly sensitive to surface roughness, dielectric constant variation and topography, and it can also probe the subsurface materials. Both data sets are therefore very complementary.

Abstract

The joint NASA-ESA-ASI Cassini- Huygens mission reached the saturnian system on July 1st 2004. It started the observations of Saturn's environment including its atmosphere, rings, and satellites (Phoebe, Iapetus and Titan). Titan, one of the primary scientific interests of the mission, is veiled by an ubiquitous thick haze [1]. Its surface is unreachable to ultraviolet and visible wavelengths, but can be seen in some infrared atmospheric windows and for greater wavelengths, in the case of an unclouded low atmosphere [2,3]. Onboard the Cassini spacecraft, the VIMS (Visual and Infrared Mapping Spectrometer) instrument has already proved to be able to successfully pierce the veil of the hazy moon and image its surface in the infrared wavelengths, taking hyperspectral images in the range 0.4 to 5.2 ?m. Since July 2004, VIMS acquired image cubes with spatial resolution ranging from a few tens of kilometers down to less than one kilometer per pixel, demonstrating its capability for mapping more than 70% of Titan's surface and studying its composition and geology [4,5,6,7,8,9,10,11]. Also in the Cassini orbiter payload is the Ku-band RADAR experiment that can operate in altimeter mode. Exclusively dedicated to Titan's observations, this second active mode has been designed primarily to retrieve Titan's surface elevation and study its topography. We present here the comparative analysis of the altimeter track recorded during the first Titan flyby (26 October 2004, tagged TA) and VIMS images over the same regions acquired during the 13th flyby (30 April 2006). In particular, we present here the first nontopographic analysis of Cassini altimeter data along with a tentative correlation with VIMS observations.

Abstract

A marked dichotomy in the density distribution of the Uranian satellites has been observed. The densities of Ariel and Umbriel are similar to those of the inner satellites of Saturn, and are consistent with a composition of 40 percent rock and 60 percent water ice, while Titania and Oberon appears to have much higher densities. It is argued here that the problem posed by this density distribution arises from a misunderstanding of the orbital dynamics and may be imaginary. It is also shown that the observed eccentricities of the inner satellites, Ariel and Miranda, may be partly forced by the outer satellites, and that these forced eccentricities may be maintained despite strong tidal damping.
