Methane Background Levels at Gale Crater, Mars

This mosaic of four images from NASA's Mars rover Curiosity shows detailed texture in a ridge that stands higher than surrounding rock. The rock is at a location called 'Darwin,' inside Gale Crater.

This image from NASA's 2001 Mars Odyssey spacecraft is of Lismore Crater. This crater, located in Chryse Planitia, is relatively unmodified, meaning it appears very much like it did when it first formed.

This observation from NASA's Mars Reconnaissance Orbiter shows the edge of a dark dune field on the floor of Proctor Crater in the Southern highlands of Mars. The dark dunes are composed of basaltic sand that has collected on the bottom of the crater.

Could This Be the Mars Soviet 3 Lander?

This image from NASA's Mars Global Surveyor and Mars Odyssey spacecraft shows the context for orbital observations of exposed rocks that had been buried on Mars. The area is dominated by the Huygens crater, which is about the size of Wisconsin.

This non-circular pit seen in this image from NASA's Mars Reconnaissance Orbiter is due to a low angle impact from an asteroid or comet. The raised plateau west of the crater was where most of the impact debris landed.

This image demonstrates how engineers place the drill carried by NASA's Mars rover Curiosity onto rock targets. They first set down the drill's two stabilizing prongs near the target, as shown by the dashed line.

This image shows the topography, with shading added, around the area where NASA's Curiosity rover landed. An alluvial fan, or fan-shaped deposit where debris spreads out downslope, has been highlighted in lighter colors for better viewing.

This picture of a heart-shaped feature in Arabia Terra on Mars was taken on May 23, 2010, by NASA's Mars Reconnaissance Orbiter. A small impact crater near the tip of the heart is responsible for the formation of the bright, heart-shaped feature.
