This picture from NASA's Dawn spacecraft shows a portion of the northeastern rim of Yalode Crater, one of the largest impact features on Ceres. A set of narrow, roughly parallel fractures can be seen at top center.
This image montage features a two-dimensional radar cross section of Mars' north polar cap collected by SHARAD instrument on NASA's Mars Reconnaissance Orbiter spacecraft (top), and a color image mosaic of the polar cap from NASA's Viking project (bottom)
This picture from NASA's Dawn spacecraft shows craters near the equator of Ceres. Faint patches and streaks of bright material can be seen in various parts of the scene. The two largest craters have streaks of material on their walls.
This picture from NASA's Dawn spacecraft shows a network of canyon-like features near the center of Ezinu Crater on Ceres. Ezinu measures about 72 miles (116 kilometers) in diameter and was named for the Sumerian goddess of grain
NASA's New Horizons scientists have spotted an expanse of terrain they describe as 'fretted' (bright plains divided into polygon-shaped blocks by a network of dark, connected valleys) in Pluto's informally named Venera Terra region.
This image from NASA's Dawn spacecraft shows Attis Crater on Ceres, which measures 14 miles (22 kilometers) in diameter. The long shadows in and around the crater reflect Attis's far-southern location.
This image from NASA's Mars Reconnaissance Orbiter spacecraft the valley networks on Mars are terrains eroded by flowing water billions of years ago. Where bedrock is well exposed, a variety of colors due to altered minerals and polygonal patterns.
Bedrock Exposures on the Floor of Bakhuysen Crater
This image from NASA's Mars Reconnaissance Orbiter spacecraft shows an exposure of bedrock on the floor of Bakhuysen Crater, an impact crater in Noachis Terra. The bedrock is highly fragmented and fractured.
This image from NASA's Mars Reconnaissance Orbiter spacecraft shows a roughly 3-kilometer impact crater, formed on the sloping walls of Tithonium Chasma, part of the large Valles Marineris canyon system.
This image from NASA's Dawn spacecraft shows the western rim of Azacca Crater on Ceres. A smaller impact feature sits on its flank. Of particular interest in this scene is the great number of small, bright spots, in the southern part of the image.
