The NASA - Cassini Spacecraft, once again, used its special InfraRed Glasses to peer through Titan's Haze and monitor the Always intriguing Surface of this Saturnian moon. Here, Cassini has recaptured the Equatorial Region of Titan dubbed "Senkyo". The Dark Surface Features so very well visible here are thought to be vast Dunes made of Hydrcarbon Particles that precipitated out of the Titanian Atmosphere. Also visible, at about 1 o' clock of Titan's disk, you can see the largest body of Liquid Hydrocarbons which has, so far, been discovered on this moon: the beautiful (and mysterious) Kraken Mare.


This view looks toward Saturn-facing Hemisphere of Titan; North is up and rotated to the left (Sx). The image was taken with the NASA - Cassini Spacecraft Narrow-Angle Camera on June 16, 2013, using a Spectral Filter that was sensitive to Wavelengths of Near-InfraRed Light centered at 938 nanometers.


This frame (which is an Original NASA - Cassini Spacecraft b/w frame published on the NASA - Planetary Photojournal with the ID n. PIA 17134) has been additionally processed, contrast enhanced, magnified to aid visibility of the details, Gamma corrected and then colorized, according to an educated guess carried out by Dr Paolo C. Fienga/LXTT/IPF, in what they should be its 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 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 Titan - as it is in this frame - would appear, to an average human eye, a little bit lower than it has been shown (or, better yet: interpreted) here.
