Enceladus' "crispy & fractured" surface (false colors)
|
Extending through the center of this image is a system of rifts 3 Km wide and lanes of grooved terrain 20 Km wide, which separate 2 distinct geological provinces. To the right of the boundary is older, cratered terrain - a region peppered with craters ranging from 10 Km in diameter, down to craters near the limit of resolution. The region is believed to be old because it has accumulated a relatively high density of impact craters over time and the topography is soft and muted, suggesting that it is covered by a layer of particulate materials. The cratered terrain is cut crosswise by numerous faults and fractures ranging in width from hundreds of meters to a few Km. On the left side of the scene are grooved, icy plains. This broad, relatively flat region is scored by an extensive band of parallel grooves that appear to subdivide the surface into narrow lanes approx. 1 Km wide. The low abundance of impact craters and crisp relief on topographic features here imply that this region is geologically much younger than the cratered terrain at the right.
