Two 2001 images from NASA's Mars Global Surveyor orbiter show a dramatic change in the planet's appearance during a dust storm.

A cross-section of a thick sheet of underground ice is exposed at the steep slope (or scarp) that appears bright blue in this enhanced-color view from NASA's Mars Reconnaissance Orbiter.

At this wedge-shaped pit on Mars, the steep slope (or scarp) at the northern edge exposes a cross-section of a thick sheet of underground water ice in this image from NASA's Mars Reconnaissance Orbiter.

This inner slope of a Martian crater has several of the seasonal dark streaks called "recurrent slope lineae," or RSL, that a November 2017 report interprets as granular flows, rather than darkening due to flowing water. The image is from the HiRISE camera on NASA's Mars Reconnaissance Orbiter.

This diagram illustrates an interpretation for the origin of some deposits in the Eridania basin of southern Mars as resulting from seafloor hydrothermal activity more than 3 billion years ago.

The Eridania basin of southern Mars is believed to have held a sea about 3.7 billion years ago, with seafloor deposits likely resulting from underwater hydrothermal activity. This graphic shows estimated depths of water in that ancient sea. The map covers an area about 530 miles wide.

This view of a portion of the Eridania region of Mars shows blocks of deep-basin deposits that have been surrounded and partially buried by younger volcanic deposits. The image was taken by the Context Camera on NASA's Mars Reconnaissance Orbiter and covers an area about 12 miles wide.

The feature that appears bright blue at the center of this scene is NASA's Curiosity Mars rover on the northwestern flank of Mount Sharp, viewed by NASA's Mars Reconnaissance Orbiter. Curiosity is approximately 10 feet long and 9 feet wide (3.0 meters by 2.8 meters).

NASA's Mars Reconnaissance Orbiter arrived at Mars on March 10, 2006. Over the past decade, the mission has shown how dynamic Mars remains today, as well as how diverse its past environmental conditions have been.

This graphic shows the route that NASA's Mars Exploration Rover Opportunity drove in its final approach to "Perseverance Valley" on the western rim of Endeavour Crater during spring 2017.

The bright landing platform left behind by NASA's Mars Exploration Rover Opportunity in 2004 is visible inside Eagle Crater, where "Opportunity Lander" is indicated in this annotated, April 8, 2017, image from NASA's Mars Reconnaissance Orbiter.

The bright landing platform left behind by NASA's Mars Exploration Rover Opportunity in 2004 is visible inside Eagle Crater, at upper right in this April 8, 2017, observation by NASA's Mars Reconnaissance Orbiter.

This map shows the footprints of images taken by the HiRISE camera on NASA's Mars Reconnaissance Orbiter as part of advance analysis of the area where NASA's InSight mission will land in 2018. The final planned image of the set will fill in the yellow-outlined rectangle on March 30, 2017.

In early 2017, after more than a decade of observing Mars, the Context Camera on NASA's Mars Reconnaissance Orbiter (MRO) surpassed 99 percent coverage of the entire planet. This mosaic shows that global coverage. No other camera has ever imaged so much of Mars in such high resolution.

The Context Camera on NASA's Mars Reconnaissance Orbiter has been taking images of Mars since 2006. This animation shows, at one frame per month, how these observations have accumulated to cover more than 99 percent of Mars. No other camera has ever shown so much of Mars in such high resolution.
