Murray Buttes Mesa


This image, taken with the High Resolution Imaging Science Experiment (HiRISE) camera, shows a mesa within the "Murray Buttes" area on Mars showing a complex fracture pattern (black arrow) protruding from the eroding rock. This mesa, which likely represents a remnant of crater floor sediments, lies on top of the sedimentary rocks of the Murray Formation. NASA's Curiosity rover will be exploring this formation.

Strata Thickening in Amargosa Valley


This portion of a color mosaic taken by NASA's Mars Curiosity rover shows strata exposed along the margins of the valleys in the "Pahrump Hills" region on Mars. The scale of layering increases upward, providing what's called a "thickening upward" trend. This is consistent with a variety of ancient environments, in particular those that involved water.

This image was taken by the rover's Mast Camera (Mastcam). It has been white-balanced to show how the scene would appear under Earth's lighting conditions.

Amargosa Valley


This image from NASA's Mars Curiosity rover shows the "Amargosa Valley," on the slopes leading up to Mount Sharp on Mars. The rover is headed toward the "Pahrump Hills" outcrop, seen above the scale bar. This area represents a boundary between the plains of Gale Crater, named Aeolis Palus, and the layered slopes of Mount Sharp, or Aeolis Mons. Curiosity has recently crossed into this terrain and now is on the Mount Sharp side of the transition zone.

This image was taken by the rover's Mast Camera (Mastcam). It has been white-balanced to show how the scene would appear under Earth's lighting conditions.

Aeolis Mensae


This VIS image shows a small portion of Aeolis Mensae, a complex region of hills, plateaus and graben. The prominent channel in the lower half of the image is a fault bounded graben.

Opportunity's Tracks Along the Western Rim of Endeavour Crater


This scene from the panoramic camera (Pancam) on NASA's Mars Exploration Rover Opportunity looks back toward part of the west rim of Endeavour Crater that the rover drove along, heading southward, during the summer of 2014.

The vista merges multiple Pancam exposures taken on August 15, 2014, during the 3,754th Martian day, or sol, of Opportunity's work on Mars.

The high point on the rim in the left half of the scene is the southern end of "Murray Ridge." Tracks from drives from mid-July 2014 are faintly visible near there, and tracks from subsequent drives advance to the foreground. For scale, the distance between Opportunity's parallel wheel tracks is about 3.3 feet (1 meter).

The most distant visible tracks are from nearly half a mile (more than 700 meters) prior to Opportunity's arrival at the viewpoint from which this scene was recorded.

This version of the image is presented in approximate true color by combing exposures taken through three of the Pancam's color filters, centered on wavelengths of 753 nanometers (near-infrared), 535 nanometers (green) and 432 nanometers (violet).

A false-color version, at http://photojournal.jpl.nasa.gov/catalog/PIA18605, makes the tracks more visible. A video at http://www.jpl.nasa.gov/video/?id=1325 places the scene into context of the rover's entire route of more than 25 miles (40 kilometers) since its 2004 landing. A map indicating the rover's Sol 3754 location (as the location reached by a Sol 3752 drive) is online at http://mars.nasa.gov/mer/mission/tm-opportunity/opportunity-sol3757.html.

Ma'adim Vallis


This VIS image shows a portion of Ma'adim Vallis, which is a large channel that enters Gusev Crater from the south. Gusev Crater is the "home" of the MER rover named Spirit.
