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-Senkyo_Region-PIA11636-PCF-LXTT-IPF.jpgThrough the Fog: Senkyo (Absolute Natural Colors; credits for the additional process. and color.: Dr Paolo C. Fienga/Lunar Explorer Italia/Italian Planetary Foundation)107 visiteThe very low Albedo Feature (---> Region) known as Senkyo, is slightly visible here, through the haze of Titan's Atmosphere. Prominent dark areas found in Titan's Equatorial Region appear to contain vast and continuous Dunefields, discovered by the Cassini Radar Experiment and likely composed of Dust Particles that drop from Titan's unique, smoggy Atmosphere. The almost circular Feature visible to the left of the image center appears to belong to the Surface of Titan, but it could also be the result of either a peculiar configuration of some low Clouds, or a bizarre-looking image artifact. This view looks toward Saturn-facing Side of Titan and is centered on Terrain at about 1° South Latitude and 345° West Longitude. North on Titan is up, and rotated 10° to the right.
The image was taken with the NASA - Cassini Spacecraft Narrow-Angle Camera on October 12, 2009, using a spectral filter sensitive to Wavelengths of Near-InfraRed Light centered at 938 nanometers. The view was acquired at a distance of approximately 296.000 Km (such as about 184.000 miles) from Titan and at a Sun-Titan-Cassini Spacecraft, or Phase, Angle of 11°. Image scale is roughly 2 Km (such as a little more than 1 mile) 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 11636) has been additionally processed and then colorized, according to an informed speculation carried out by Dr Paolo C.

Titan-Shangri_La_Region-PIA08971-PCF-LXTT-IPF.jpgThrough the Fog: Shangri-la (Absolute Natural Colors; credits for the additional process. and color.: Dr Paolo C. Fienga/Lunar Explorer Italia/Italian Planetary Foundation)106 visiteThis view of Titan's Surface highlights a small portion of the North-Western Region known as Shangri-la: a large, Equatorial, Dark Region that radar observations revealed to be covered by Longitudinal Dunefields. The bright, Circular Feature visible right of center is a potential Impact Crater (one of the very few Impact Craters that have been spotted on Titan so far).
North on Titan is up and rotated about 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 938 and 619 nanometers. The images were taken with the NASA - Cassini Spacecraft Narrow-Angle Camera on May 13, 2007, at a distance of approximately 125.000 Km (such as about 77.000 miles) from Titan. Image scale is roughly 1 Km (such as approx. 0,6 miles) per pixel. Due to scattering of light by Titan's hazy Atmosphere, the size of the Surface Features that can be resolved is a few times larger than the actual pixel scale.
This picture (which is an Original NASA - Cassini Spacecraft b/w image-mosaic published on the NASA - Planetary Photojournal and identified by the n. PIA 08971) has been additionally processed and then colorized, according to an informed speculation carried out by Dr Paolo C.

Titan-PIA10243.jpgUnder the Fog...103 visiteCaption NASA:"This graphic depicts a cross-section of the Saturnian moon Titan. Cassini scientists speculate there may be a layer of liquid water mixed with ammonia about 100 Km (approx. 62 miles) below the surface of Titan.
The assumption that Titan contains an internal ocean was generated from data gleaned from Cassini's Synthetic Aperture Radar during 19 separate passes over Titan between October 2005 and May 2007. Using data from the radar’s early observations, the scientists and radar engineers established the locations of 50 unique landmarks on Titan's surface. They then searched for these same lakes, canyons and mountains in the reams of data returned by Cassini in its later flybys of Titan. What they found was prominent surface features seemed to shift from their expected positions by up to 31 Km (about 19 miles). Since the features could not have really moved, the apparent shift told the scientists and engineers that Titan was spinning about its axis in a previously unsuspected manner. The pre-Cassini model of Titan's spin accounted for the gravitational fields of Saturn and other nearby planets and moons but omitted other smaller less well understood effects. Since the observed spin of Titan does not fit this model, other influences, such as the seasonal changes in the motion of its atmosphere must also be important. It is difficult to explain how such relatively low energy phenomena could have such a pronounced influence on Titan's spin unless the moon's icy crust was decoupled from its core by an internal ocean. If the crust were decoupled from the core, atmospheric fluctuation alone could account the observed spin".MareKromium

Titan-Clouds-North_Polar_Clouds-PIA10434.jpgPolar Clouds on Titan (IR View - False Colors; credits: Lunexit)103 visiteCaption NASA:"Frigid Titan continues to prove itself a remarkably complex and dynamic world. Here, bright clouds are seen encircling the moon's North Polar Region.
The Cassini Spacecraft has revealed the presence of great lakes and seas of liquid hydrocarbons on this part of Titan's surface (see PIA08365 and PIA08930).
An extended, high-altitude haze hovers above the limb of Titan at top of the image.
The image was taken with the Cassini Spacecraft narrow-angle camera on April 26, 2008 using a spectral filter sensitive to wavelengths of Infrared Light centered at 938 nanometers. The view was acquired at a distance of approx. 786.000 Km (such as about 488.000 miles) from Titan.
Image scale is roughly 5 Km (a little more than 3 miles) per pixel".MareKromium

Titan-PIA12320.jpgCrescent Titan (Natural Colors; credits: NASA/JPL/Space Science Institute & Lunexit)103 visiteCaption NASA:"Titan's golden, smog-like atmosphere and complex layered hazes appear to Cassini as a luminous ring around the planet-sized moon. The world beneath that haze has become slightly less mysterious under the gaze of Cassini and its Huygens probe, but many new discoveries await.
This mosaic view of Titan represents "Target 3" in the fall 2009 edition of the Cassini Scientist for a Day contest. (See http://saturn.jpl.nasa.gov/education/scientistforaday8thedition/.) The contest is designed to give students a taste of life as a scientist by challenging them to write an essay describing the value of one target choice among three for Cassini to image.
Images taken using red, blue and green spectral filters were combined to create this color view. Six images -- two sets of three colors -- were combined to create the mosaic. The images were acquired with the Cassini wide-angle camera on Oct. 12, 2009 at a distance of approx. 145.000 Km (such as about 90.000 miles) from Titan".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-Senkyo_Region-PIA11577-PCF-LXTT-IPF.jpgThrough the Fog: Senkyo (Absolute Natural Colors; credits for the additional process. and color.: Dr Paolo C. Fienga/Lunar Explorer Italia/Italian Planetary Foundation)102 visiteThe NASA - 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, that is centered at 28° South Latitude and 334° West Longitude, shows us a small part of the Albedo Feature named Senkyo (actually it is a very large Region that the Planetary Scientists consider like a true Continent) which is located on the Trailing Hemisphere of Titan.
The image was taken with the NASA - 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 approximately 251.000 Km (such as about 156.000 miles) from Titan and at a Sun-Titan-Cassini Spacecraft, or Phase, Angle of 27°. Image scale is about 1 Km (such as 3281 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 11577) 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
