Titan-PIA22481-1.jpgThe Great Seas and Lakes of Titan172 visiteCaption NASA:"During NASA's Cassini mission's final distant encounter with Saturn's giant moon Titan, the Spacecraft captured this view of the truly enigmatic moon's North Polar landscape of Lakes and Seas, which are filled with liquid Methane and Ethane.
Punga Mare (about 240 miles, or approx. 386,2 Km, across) is seen just above the center of the mosaic, with Ligeia Mare (roughly 300 miles, or about 48,3 Km, wide) below center and vast Kraken Mare stretching off 730 miles (such as approx. 1.174,8 Km) to the left of the mosaic. Titan's numerous smaller and still Unnamed Lakes can be seen around the seas and scattered around the right side of the mosaic. Among the ongoing mysteries about Titan is how these Seas and Lakes are formed.
Another mystery at Titan has been the weather. With its extremely dense Atmosphere, Titan has a Methane Cycle much like Earth's Water Cycle of evaporation, cloud formation, rainfall, surface runoff into Rivers, and collection in Lakes and Seas.
During Titan's Southern Summer, the Cassini Spacecraft also observed Cloud activity over the South Pole.
However, typical of observations taken during Northern Spring and Summer, the view here reveals only a few small clouds. They appear as bright features just below the center of the mosaic, including a few above Ligeia Mare.
The images in this mosaic were taken with the ISS Narrow-Angle Camera, using a spectral filter sensitive to wavelengths of Near-InfraRed Light centered at 938 nanometers.
They were captured on Sept. 11, 2017, during Cassini's last encounter with Titan. Four days later, Cassini was deliberately plunged into the Atmosphere of Saturn.
The view was obtained at a distance of approximately 87.000 miles (a little less than 140,013 Km) from Titan. Image scale is about 0,5 miles (approx. 800 meters) per pixel.
The image is an Orthographic Projection centered on 67,19° North Latitude and 212,67° West Longitude.
Note: an Orthographic View is most like the view seen by a distant observer looking through a telescope".MareKromium

Titan-Regions-Adiri-PIA12621-PCF-LXTT-IPF.jpgThrough the Fog: Adiri (Absolute Natural Colors; credits for the additional process. and color.: Dr Paolo C. Fienga/Lunar Explorer Italia/Italian Planetary Foundation)112 visiteThe NASA - Cassini Spacecraft peers through the Dark and Hazy Atmosphere of Titan, this time looking at a Region called Adiri, and located to the West of the Landing Site of the ESA - Huygens Probe, on the Anti-Saturn Side of the moon. This view is centered on Terrain at 22° South Latitude and 209° West Longitude. North on Titan is up and rotated 36° to the right. The dark Circular Feature visible slightly on to the right of the image center, at about 2 o'clock (and that looks like a well preserved Impact Crater seen from atop), could actually be an Image-Artifact.
The image was taken with the NASA - Cassini Spacecraft Narrow-Angle Camera on December 12, 2009, using a spectral filter sensitive to Wavelengths of Near-InfraRed Light centered at 938 nanometers. The view was obtained at a distance of approximately 130.000 Km (such as about 81.000 miles) from Titan. Image scale is 766 meters (such as 2513 feet) per pixel.
This picture (which is an Original NASA - Cassini Spacecraft b/w frame published on the NASA - Planetary Photojournal and identified by the n. PIA 12621) has been additionally processed and then colorized, according to an informed speculation carried out by Dr Paolo C. Fienga (LXTT-IPF), in Absolute Natural Colors (such as the colors that a human eye would actually perceive if someone were onboard the NASA - Cassini Spacecraft and then looked outside, towards the Saturnian moon Titan), by using an original technique created - and, in time, dramatically improved - by the Lunar Explorer Italia Team. Different colors, as well as different shades of the same color, mean, among others, the existence of different Elements present in the Atmosphere and on the Surface of Titan, each having a different Albedo (---> Reflectivity) and Chemical Composition.
Note: it is possible (but we, as IPF, have no way to be one-hundred-percent sure of such a circumstance), that the actual luminosity of the Albedo Feature seen in this frame would appear, to an average human eye, way lower than it has been shown (better yet: interpreted) here.MareKromium

Titan-Regions-Adiri_Region-IMG002645.jpgAdiri Region72 visiteCaption NASA:"Bright mid-latitude clouds near the bottom of this view hint at the ongoing cycling of Methane on Titan. These cloud streaks are near the same latitude as similar clouds observed above different longitudes on Titan.
The view is centered on Titan's Trailing Hemisphere, over the 1.700 Km (such as about 1050 mile) wide bright Region known as "Adiri".
North on Titan is up and rotated 15° to the right.
This view was created by combining multiple images taken using a combination of spectral filters sensitive to wavelengths of infrared light centered at 939 and 742 nanometers
The images were taken with the Cassini spacecraft wide-angle camera on May 13, 2007 at a distance of approx. 104.000 Km (about 65.000 miles) from Titan. Image scale is roughly 12 Km (about 8 miles) 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
