These beautiful Absolute Natural Color views of the Saturnian moon Hyperion reveal crisp details across the strange, tumbling moon's Surface. Differences in color represent differences in the composition of the Surface Materials; both views (CTX Frame and EDM) were obtained during the Cassini's close Fly-By that occurred on September, 26, 2005.
The images were taken by the NASA - Cassini Spacecraft's narrow-angle camera at a distance of approx. 62.000 Km (about 38.500 miles) from Hyperion and at a Sun-Hyperion-Cassini Angle (a.k.a. "Phase Angle") of 52°. The image scale is 362 mt (about 1200 feet) per pixel.


These two frames have been colorized 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 Hyperion), by using an original technique created - and, in time, dramatically improved - by the Lunar Explorer Italia Team.
