Opportunity's Rear-Facing View Ahead After a Drive
NASA's Mars rover Opportunity captured this view southward just after completing a 338-foot (103-meter) southward drive, in reverse, on Aug. 10, 2014. The foreground of this view from the rover's Navcam includes the rear portion of the rover's deck.
This image from NASA's 2001 Mars Odyssey spacecraft shows dark slope streaks in an unnamed crater in Terra Sabaea. These features are believed to be formed by material moving downslope, removing the dust cover and revealing darker material.
This mantle observed by NASA's Mars Reconnaissance Orbiter is thought to be deposited as snow during periods when the angle of the tilt of Mars' rotational axis-called obliquity-is much higher, which last happened around 10 million years ago.
A Possible Landing Site in Aram Dorsum for the ExoMars Rover
This image captured by NASA's Mars Reconnaissance Orbiter is of an area called Aram Dorsum (also known by its old name, Oxia Palus) that has been suggested for the 2018/2020 ExoMars Rover because it contains an ancient, exhumed alluvial system.
This image from NASA's 2001 Mars Odyssey spacecraft shows a landslide deposit within a complex crater (note the ejecta to the top and bottom of the image). There is a smaller complex crater on the ejecta to the north of the larger crater.
Candidate Drilling Target on Mars Doesn't Pass Exam
This image from the front Hazcam on NASA's Curiosity Mars rover shows the rover's drill in place during a test of whether the rock beneath it, 'Bonanza King,' would be an acceptable target for drilling to collect a sample.
Curiosity's Brushwork on Martian 'Bonanza King' Target
NASA's Curiosity Mars rover used the Dust Removal Tool on its robotic arm to brush aside reddish, more-oxidized dust, revealing a gray patch of less-oxidized rock material at a target called 'Bonanza King,' visible from the rover's Mastcam.
This Aug. 12, 2012, image from the Mastcam on NASA's Curiosity Mars rover shows an outcrop that includes the 'Bonanza King' rock under consideration as a drilling target. Raised ridges on the flat rocks are visible at right.
This July 29, 2014, panorama combines several images from the navigation camera on NASA's Mars Exploration Rover Opportunity to show the rover's surroundings after surpassing 25 miles (40.23 kilometers) of total driving on Mars.
