Titan-Regions-Senkyo_Region-PIA11577-01.jpgLight and dark Surface Features of Senkyo57 visiteCaption NASA:"The Cassini Spacecraft peers through the hazy Atmosphere of Titan for a close view of light and dark Terrain on Saturn's largest moon.
This view is centered on Terrain at 28° South Lat. and 334° West Long. and shows a small part of the albedo feature named Senkyo on the Trailing Hemisphere of Titan.
The image was taken with the Cassini Spacecraft narrow-angle camera on July 9, 2009 using a spectral filter sensitive to wavelengths of Near-InfraRed Light centered at 938 nanometers. The view was obtained at a distance of approx. 251.000 Km (such as about 156.000 miles) from Titan and at a Sun-Titan-Spacecraft, or Phase, Angle of 27°.
Image scale is about 1 Km (3281 feet) per pixel".MareKromium

Titan-W00051746.jpgCrescent Titan (possible True Colors; credits: Lunar Explorer Italia)55 visiteCaption NASA:"W00051746.jpg was taken on December 06, 2008 and received on Earth December 06, 2008. The camera was pointing toward TITAN that, at the time, was approx. 313.546 Km away.
The image was taken using the CL1 and CL2 filters".MareKromium

Titan-PIA09846.jpgAlien Weather (False Colors; credits: Lunexit)102 visiteA bright streak of cloud graces the Northern Skies of Titan.
This is the second time the Cassini spacecraft's imaging cameras have spotted clouds at 60° North Latitude on Titan - the previous occasion being the Feb. 2007 observations during which the cameras saw the dark, hydrocarbon lakes that cover much of the North.
That cloud feature is visible at the bottom of the still image in Exploring the Wetlands of Titan. The circular, 400-Km wide impact feature Menrva can be seen near center.
North on Titan is up and rotated 26° to the right.
The image was taken with the Cassini spacecraft narrow-angle camera on Jan. 20, 2008 using a combination of spectral filters sensitive to wavelengths of polarized infrared light centered at 938 and 746 nanometers. The view was acquired at a distance of approx. 1,3 MKM (800.000 miles) from Titan and at a Sun-Titan-spacecraft, or phase, angle of 58°. Image scale is roughly 8 Km per pixel. Due to scattering of light by Titan's hazy atmosphere, the sizes of surface features that can be resolved are a few times larger than the actual pixel scale".MareKromium

Titan-W00036545.jpgThe "uneven" Haze of Titan (possible Natural Colors - elab. Lunexit)71 visiteNoi osserviamo le immagini e quindi ci poniamo domande. Eccone una, per noi e per Voi: può essere che sia la cosiddetta "super-rotazione" delle nuvole di Titano la (sola o, se non altro, la maggior) causa delle - evidenti - irregolarità che caratterizzano gli strati più alti della sua atmosfera? Avete opinioni al riguardo?

Titan-Huygens_Landing_Site-03-IMG002628-br500.jpgCoastline on Titan54 visiteThe deposits form when solar ultraviolet radiation and charged particles react at high altitudes with Titan’s abundant methane to produce carbon- and hydrogen-bearing (hydrocarbon) molecules like ethane and acetylene, and more complex nitrogen-bearing molecules generally called tholins. These products drift down to the surface as aerosols much in the same way smog particles on Earth form and coat surfaces. On Titan however these deposits may accumulate to thicknesses of hundreds of metres deep.
The dunes are composed of sand-sized material that agglomerated, either during its descent or when reworked by geological processes on the surface. The ice and organic landforms are as different from one another as they are spectacular. To the north of Huygens’ landing site are the bright highlands, displaying channels in a very ramified pattern, branching four or five times as they climb into the hills.
Stereoscopic images from the Descent Imager/Spectral Radiometer (DISR) camera on Huygens have now been analysed and show that some of the ridges between the channels rise to 150 - 200 metres in height, with slopes of thirty degrees. “This is extremely rugged terrain,” says Soderblom. The shape suggests that they are drainage channels, cut by liquid methane falling as rain.
