Saturn-PIA09828.jpgNorthern Latitudes (possible natural colors; credits: Lunexit)55 visiteCaption NASA:"As seasons change on Saturn, and sunlight creeps farther north, the region surrounding the North Pole is steadily coming to light. This scene reveals many features in Saturn's dynamic and beautiful Atmosphere, including a detail largely obscured from the imaging cameras until now: on the Terminator at center right is part of the Polar Hexagon, which was previously observed by Cassini's Visible and Infrared Mapping Spectrometer (VIMS) and Composite Infrared Spectrometer (CIRS).
These instruments used heat radiated from Saturn to observe the Polar Hexagon (rather than reflected sunlight, as is the case in this view). The Hexagon was first imaged by the Voyager spacecraft more than 25 years ago.
The view looks toward the unilluminated side of the Rings from about 38° above the Ring-Plane and is centered on a region 63° north of the Saturnian Equator.
The image has been brightened to show details at high Northern Latitudes, where solar illumination is presently weak.
The image was taken with the Cassini spacecraft wide-angle camera on Jan. 2, 2008 using a combination of spectral filters sensitive to wavelengths of polarized infrared light centered at 752 and 705 nanometers. The view was acquired at a distance of approx. 930.000 Km (about 578.000 miles) from Saturn.
Image scale is roughly 52 Km (approx. 32 miles) per pixel".MareKromium

Saturn-PIA09854.jpgThe Southern Hemisphere of Saturn (natural colors - credits: NASA/SSI)55 visiteCaption NASA:"Saturn's Southern Hemisphere is glimpsed through the Gossamer Veil of its Rings. Ring shadows adorn the low Northern Latitudes.
This view looks toward the unilluminated side of the Rings from about 22° above the Ring-Plane. Images taken using red, green and blue spectral filters were combined to create this natural color view.
The images were acquired with the Cassini spacecraft wide-angle camera on Dec. 16, 2007 at a distance of approx. 1,5 MKM (about 908.000 miles) from Saturn.
Image scale is roughly 84 Km (approx. 52 miles) per pixel".MareKromium

SOL287-1.jpgSpirit's Robotic Arm and Surface in True Colors - Sol 287 (1 - credits: Dr Gianluigi Barca)55 visiteRepetita iuvant: dopo il Dr Marco Faccin, ora è tempo di fare i nostri grandissimi complimenti per la splendida elaborazione in colori naturali della superficie di Marte e del R.A. del MER Spirit ottenuta dal nostro Carissimo Amico e Partner, il Dr Gianluigi Barca (Presidente della Sez. Liguria e Piemonte di Lunexit).
Anche la sua ricostruzione cromatica del R.A. di Spirit - come del terriccio marziano ad esso sottostante - è eccezionale, realistica e di gran lunga migliore rispetto ad analoghe interpretazioni operate dalla (pur grande) NASA.
Congratulations for a job VERY WELL done! (again)MareKromium
