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 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.

This movie clip shows a global map of Mars with atmospheric changes from Feb. 18, 2017, through March 6, 2017, a period when two regional-scale dust storms appeared. It combines hundreds of images from the Mars Color Imager (MARCI) camera on NASA's Mars Reconnaissance Orbiter.

NASA's Mars Reconnaissance Orbiter has been observing Mars since 2006, enabling it to document many types of changes, such as the way winds alter the appearance of this recent impact site. The orbiter's HiRISE camera took the four images used in this animated sequence in 2007, 2008, 2010 and 2012.

This photograph from Shiprock in northwestern New Mexico shows a ridge roughly 30 feet (about 10 meters) tall that formed from lava filling an underground fracture then resisting erosion better than the material around it did.

This stereo view shows an area on Mars where narrow rock ridges intersect at angles forming corners of polygons. It combines two observations from the HiRISE camera on NASA's Mars Reconnaissance Orbiter and appears three-dimensional when viewed through red-blue glasses with the red lens on the left.
