ZZ-Mercury-Terminator-PIA10939.jpgSveinsd髏tir Crater and Beagle Rupes (natural colors; credits: Lunexit)59 visiteNamed for J煤l铆ana Sveinsd贸ttir, an Icelandic painter and textile artist, Sveinsd贸ttir Crater superimposed by Beagle Rupes is a distinctive feature on Mercury's landscape. Unusually elliptical in shape, the Crater was produced by the impact of an object that hit Mercury鈥檚 Surface obliquely. More than 600 Km (about 370 miles) long and one of the largest fault scarps on the Planet, Beagle Rupes marks the surface expression of a large thrust fault believed to have formed as Mercury cooled and the entire planet shrank. Beagle Rupes crosscuts Sveinsd贸ttir Crater and has uplifted the easternmost portion (right side portion) of the crater floor by almost a kilometer, indicating that most of the fault activity at Beagle Rupes occurred after the impact that created Sveinsd贸ttir. Crosscutting relationships such as this are used to understand the sequence in time of the different processes that have affected Mercury鈥檚 evolution.

ZQ-Mercury-PIA10984.jpgCraters "Deformed" and "Shortened" on Mercury59 visiteNumerous examples of craters that have been deformed and shortened by younger faults have been identified on images returned from MESSENGER鈥檚 first flyby of Mercury. In three cases shown here (arrows), portions of the floor and rim of a crater were buried when a large block of crust was thrust over the crater during the formation of a prominent fault scarp or cliff. By comparing the estimated size and shape of the original, undeformed crater with the crater鈥檚 current geometry, scientists can infer the amount of movement between the two crustal blocks on either side of the fault. This figure was recently published in Science magazine.
For each of the three examples of deformed and shortened craters shown here, movement on the faults buried at least a kilometer of the original crater. A: 17-Km (11-mile) diameter crater (arrows) shortened by Beagle Rupes. B: 5-Km (3-mile) diameter crater deformed near the rim of an older, larger crater, shown enlarged in the box on the lower left. C: 11-Km (7-mile) diameter crater (arrows) shortened by a North/West-South/East-trending fault scarp.MareKromium

The_Rings-PIA10454.jpgOut of the Darkness (natural colors; credits: NASA)59 visiteCaption NASA:"Saturn's rings burst out of shadow and curve gracefully around the Planet.
Prometheus (86 Km, or 53 about miles across at its widest point) appears as a bright speck touching the inside of the narrow F-Ring. Atlas (30 Km, or approx. 19 miles across at its widest point) is also visible, faintly, upward and to the left of Prometheus, just outside the A-Ring edge. Saturn's shadow cuts across the Rings at top right.
Several dark, narrow spokes are faintly visible near the B-Ring ansa, left of center.
This view looks toward the unilluminated side of the Rings from about 13掳 above the Ring-Plane. Images taken using red, green and blue spectral filters were combined to create this natural color view. The images were obtained with the Cassini Spacecraft wide-angle camera on July 4, 2008 at a distance of approx. 1,2 MKM (about 775.000 miles) from Saturn.
Image scale is roughly 71 Km (about 44 miles) per pixel".MareKromium
