- In this image taken by Curiosity's Mast Camera, the Alpha Particle X-Ray Spectrometer (APXS) on NASA's Curiosity rover is pictured, with the Martian landscape in the background on the 32nd Martian day, or sol, of operations on the surface on September 7, 2012, PDT or September 8, 2012, UTC. This image lets researchers know that the APXS instrument had not become caked with dust during Curiosity's dusty landing. Scientists enhanced the color in this version to show the Martian scene as it would appear under the lighting conditions we have on Earth, which helps in analyzing the terrain.

- An image from the Mast Camera (Mastcam) on NASA's Mars rover Curiosity shows the surface of the planet with inclined layering known as cross-bedding in an outcrop called "Shaler" on a scale of a few tenths of a meter, or decimeters (1 decimeter is nearly 4 inches) in this NASA handout released January 15, 2013.

- A view of the surface of Mars released by NASA on March 7, 2017, shows viscous, lobate flow features commonly found at the bases of slopes in the mid-latitudes of Mars, and are often associated with gullies. These are bound by ridges that resemble terrestrial moraines, suggesting that these deposits are ice-rich, or may have been ice-rich in the past.

- Portions of the Martian surface shot by NASA's Mars Reconnaissance Orbiter show many channels from 1 meter to 10 meters wide on a scarp in the Hellas impact basin, in this photograph taken January 14, 2011 and released by NASA March 9, 2011. Scientists have found the first evidence that briny water may flow on the surface of Mars during the planet's summer months, a paper published on Monday showed. Researchers found telltale fingerprints of salts that form only in the presence of water in narrow channels cut into cliff walls throughout the planet's equatorial region.

- NASA's Mars rover Curiosity's hole drilled into a rock target, "Cumberland," on Mars on May 19, 2013 is shown in this NASA photo. NASA?s Mars rover Curiosity has found carbon-containing compounds in samples drilled out of an ancient rock, the first definitive detection of organics on the surface of Earth?s neighbor planet, scientists said on Tuesday.

- NASA's Mars Exploration Rover Opportunity is shown in this handout photo released to Reuters July 29, 2014. Opportunity has set a new off-Earth, off-road distance record, logging just over 25 miles (40 km) on the surface of the Red Planet to surpass the old benchmark set in 1973 by a Russian probe on the moon.

- A billion-pixel view from the surface of Mars, from NASA's Mars rover Curiosity, offers armchair explorers a way to examine one part of the Red Planet in great detail is shown in this composite produced using 850 frames from the telephoto camera of Curiosity's Mast Camera instrument, 21 frames from the Mastcam's wider-angle camera and 25 black and white frames of the rover itself from the Navigational Camera. The photos were taken between October 5 and November 16, 2012. REUTERS/NASA/JPL-Caltech/MSSS/Handout via Reuters (OUTERSPACE - Tags: SCIENCE TECHNOLOGY) FOR EDITORIAL USE ONLY.

- The surface of the planet Mars inside Gale's Crater is shown as NASA's Mars rover Curiosity drives toward a flat rock with pale veins that may hold clues to a wet history on the planet in this NASA handout photo released January 15, 2013. If the rock meets rover engineers' approval when Curiosity rolls up to it in coming days, it will become the first to be drilled for a sample during the Mars Science Laboratory mission.

- A rock outcrop called Link pops out from a Martian surface in this NASA handout image taken by the 100-millimeter Mast Camera on NASA's Curiosity Mars rover September 2, 2012 and released September 27, 2012. Rounded gravel fragments, or clasts, up to a couple inches (few centimeters) in size are in a matrix of white material. The outcrop characteristics are consistent with a sedimentary conglomerate, or a rock that was formed by the deposition of water and is composed of many smaller rounded rocks cemented together. Scientists enhanced the color in this version to show the Martian scene as it would appear under the lighting conditions we have on Earth, which helps in analyzing the terrain.

- The left eye of the Mast Camera (Mastcam) on NASA's Mars rover Curiosity took this image of the camera on the rover's arm, the Mars Hand Lens Imager (MAHLI), during the 30th Martian day, or sol, of the rover's mission on Mars on September 5, 2012. The image shows that MAHLI has a thin film or coating of Martian dust on it. This dust accumulated during Curiosity's final descent to the Martian surface, as the Mars Science Laboratory spacecraft's descent stage (or sky crane) engines were disrupting the surface nearby. Effects of the dust were seen in the first image takenof Mars by MAHLI, on the day after landing. The mechanism at the right in this image is Curiosity's dust removal tool, a motorized wire brush.

- This color image taken August 8, 2012 from NASA's Curiosity rover, and released August 13, shows part of the wall of Gale Crater, the location on Mars where the rover landed on August 5, 2012. This is part of a larger, high-resolution color mosaic made from images obtained by Curiosity's Mast Camera. This image of the crater wall is north of the landing site, or behind the rover. Here, a network of valleys believed to have formed by water erosion enters Gale Crater from the outside. This is the first view scientists have had of a fluvial system - one relating to a river or stream from the surface of Mars.
