Craters, Slopes and Scarps on Rhea (HR)
|
Craters within craters cover the scarred face of Saturn's moon Rhea in this oblique, HR view of terrain on the moon's Western Hemisphere.
A large, degraded crater lies at the center, filled with rolling mounds and many smaller craters. A couple of linear depressions are visible in the terrain (especially at lower right), possibly marking tectonic faults. The crater is about 90 Km-wide (about 56-miles) and is located at 8,5° South Latitude and 154,9 West Longitude. The moon's icy regolith, or loose surface material, has likely been pummeled into a fine powder over the eons.
This is one of the highest-resolution images of Rhea's surface obtained during Cassini's close flyby on Nov. 26, 2005, during which the spacecraft swooped to within 500 Km of the large moon.
The clear filter image was acquired with the wide-angle camera at an altitude of approx. 620 Km above Rhea.
Image scale is about 85 mt (approx. 280 feet) per pixel.
