The terraced rim of the large crater named Urvara can be seen at the upper left in this view from Ceres. This image from NASA's Dawn spacecraft shows terrain in the southern hemisphere of the dwarf planet.
This image from NASA's 2001 Mars Odyssey spacecraft shows the northern margin of Tanaica Montes. These hills are cut by fractures, which are in alignment with the regional trend of tectonic faulting found east of Alba Mons.
This graphic depicts paths by which carbon has been exchanged among Martian interior, surface rocks, polar caps, waters and atmosphere, and also depicts a mechanism by which it is lost from the atmosphere with a strong effect on isotope ratio.
This image from NASA's Dawn spacecraft shows cratered terrain in the northern hemisphere of Ceres. Ikapati crater (top) appears with several flat plains filled by flows, smooth material and ejecta from the crater interior.
This image from NASA's 2001 Mars Odyssey spacecraft shows a portion of Granicus Valles. This channel system is located west of Elysium Mons and likely was created by both lava and water flow related to the Elysium Mons volcanic complex.
This view of Ceres from NASA's Dawn spacecraft shows a fresh impact crater with a flat floor. The crater is surrounded by smooth, flow-like ejecta that covers adjacent older impact craters. The crater is about 16 miles (26 kilometers) in diameter.
This image, taken by NASA's Dawn spacecraft, displays a linear structure trending from northeast to southwest (lower left to upper right). The graben might be interpreted as a chain of collapsed pits or secondary craters.
Curiosity Rover's Traverse, First 1,163 Sols on Mars
This map shows the route driven by NASA's Curiosity Mars rover from the location where it landed in August 2012 to its location in mid-November 2015, approaching examples of dunes in the 'Bagnold Dunes' dune field.
Curiosity Rover Will Study Dunes on Route up Mountain
This view from the Mast Camera (Mastcam) on NASA's Curiosity Mars rover shows a dark sand dune in the middle distance. Mount Sharp will be the first in-place study of an active sand dune anywhere other than Earth.
Dantu crater on Ceres, seen in this image from NASA's Dawn spacecraft at left, reveals structures hinting at tectonic processes that formed the dwarf planet's surface. Linear structures are spread over the crater floor.
This image of Ceres, taken by NASA's Dawn spacecraft, shows a giant, ancient impact crater with smaller craters in its interior. The large crater shows partial terracing on its southeast rim, whereas the north part is almost fully degraded.
This view from the Mars Hand Lens Imager (MAHLI) on the arm of NASA's Curiosity Mars rover shows a combination of dark and light material within a mineral vein at a site called 'Garden City' on lower Mount Sharp.
