Japetus-PIA08377.jpgCraterland... (HR - possible natural colors; elab. Lunexit)58 visiteThis HR view shows a vast range of crater sizes in the dark terrain of the Leading Hemisphere of Saturn's moon Japetus.
Across the scene, a few small bright spots indicate fresh, rayed craters where impactors have punched through the thin blanket of dark material to the cleaner ice beneath.
The slight elevation on the bottom half of the image is part of the giant Equatorial Ridge that spans a wide fraction of Japetus' circumference. The numerous craters on top of the ridge indicate that it is an old surface feature.
The mosaic consists of three image footprints across the surface of Japetus.
The view is centered on terrain near 0,5° North Latitude and 141,6° West Long.
Image scale is approx. 22 meters (72 feet) per pixel. Illumination is from the left.
The clear spectral filter images in this mosaic were obtained with the Cassini spacecraft narrow-angle camera on Sept. 10, 2007, at a distance of approx. 63.000 Km (such as about 39.000 miles) from Japetus and at a phase angle of about 125°.MareKromium

Saturn-PIA09734.jpgTurbulences59 visiteCaption NASA:"The Cassini Spacecraft has a peek beneath the hazes in Saturn's Upper Atmosphere at the swirling vortices that lurk below.
Many vortices can be seen in this image, varying in size from small to large.
The largest one in this image exhibits a collar of bright clouds surrounding the central dark core.
The view is centered on a region about 46° South of the Planet's Equator.
The image was taken with the Cassini spacecraft narrow-angle camera on Aug. 12, 2007 using a spectral filter sensitive to wavelengths of infrared light centered at 750 nanometers. The view was acquired at a distance of approx. 4,1 MKM (such as about 2,5 MMs) from Saturn.
Image scale is roughly 24 Km (about 15 miles) per pixel".MareKromium

Japetus-PIA08375.jpgThe "Voyager" Mountains58 visiteCaption NASA:"Cassini zooms in, for the first time, on the patchy, bright and dark mountains originally identified in images from the NASA Voyager spacecraft taken more than 25 years earlier. The image was acquired during Cassini's only close flyby of Iapetus, a two-toned moon of Saturn.
The terrain seen here is located on the Equator of Japetus at approximately 199° West Longitude, in the Transition Region between the moon's bright and dark Hemispheres. North is up.
The image was taken on Sept. 10, 2007, with the Cassini spacecraft narrow-angle camera at a distance of approximately 9.240 Km (5.740 miles) from Japetus. Image scale is 55 meters (180 feet) per pixel".MareKromium

Japetus-PIA08373.jpgThe "Transition Region" of Japetus: Coated Craters60 visiteCaption NASA:"Cassini surveys a bright landscape coated by dark material on Iapetus. This image shows terrain in the Transition Region between the moon's dark Leading Hemisphere and its bright Trailing Hemisphere. The view was acquired during Cassini's only close flyby of the two-toned Saturn moon.
The image was taken on Sept. 10, 2007, with the Cassini spacecraft narrow-angle camera at a distance of approximately 5.260 Km (3.270 miles) from Japetus. Image scale is 32 meters (105 feet) per pixel".MareKromium
