Storm Chaser on Mars

This series of images shows warm-season features that might be evidence of salty liquid water active on Mars today.

This image shows a portion of the central mound in the impact crater Gale that is of interest to scientists because it is composed of light-toned layered deposits. 

This is a close-up of the area in the vicinity of the Pathfinder landing site. Major features are named. The white box outlines the area of the image, where hardware is seen.

The High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter captured winter images of NASA's Phoenix Mars Lander surrounded by dry-ice frost on Mars.

A small channel cuts across the floor of a gigantic 1100-mile (1780-kilometer)-long set of flood-carved channels in a region on Mars called "Kasei Valles."

This HiRISE image shows fractured mounds on the southern edge of Elysium Planitia.

This area of Mars is shaped by lava flows from volcanic eruptions.

The largest crater in this mosaic of images taken by the Context Camera on NASA's Mars Reconnaissance Orbiter is Endeavour Crater, which is 22 kilometers (14 miles) in diameter.

This image from NASA's Mars Reconnaissance Orbiter shows many new ice blocks compared to earlier images in 2006. One of the most actively changing areas on Mars are the steep edges of the North Pol...

NASA's Mars Reconnaissance Orbiter shows bright ripples line the topography in this region, formed within a past climate. Dark dunes and sand streaks, composed of basaltic sand, have moved and fill...

This map traces where NASA's Mars rover Curiosity drove between landing at a site subsequently named "Bradbury Landing," and the position reached during the mission's 130th Martian day, or sol, (De...

This series of images shows warm-season features that might be evidence of salty liquid water active on Mars today.

In this Mars Reconnaissance Orbiter view of the Curiosity rover mission's waypoint called "the Kimberley," the red dot indicates the location of a sandstone target, "Windjana," selected for close-u...

NASA's Curiosity Mars rover can be seen in this image taken from space on May 31, 2019, by the HiRISE camera aboard the Mars Reconnaissance Orbiter. In the image, Curiosity appears as a bluish speck.

This image acquired on August 20, 2018 by NASAs Mars Reconnaissance Orbiter, shows remnants of a deposit, composed of dry ice layered together with dust and water ice, that form the south polar res...

Artist's concept of Mars Reconnaissance Orbiter

The South Polar residual cap (the part that lasts through the summer) is composed of carbon dioxide ice.

Artist concept of glacier on Mars.

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.

This image from NASA's Mars Reconnaissance Orbiter shows blocks of layered terrain within the Olympus Mons aureole. The aureole is a giant apron of chaotic material around the volcano.

Wind is one of the most active forces shaping Mars’ surface in today’s climate. Wind-carved features such as these, called “yardangs,” are common on the Red Planet.

This map shows the route driven by NASA's Mars rover Curiosity through the 43rd Martian day, or sol, of the rover's mission on Mars (Sept. 19, 2012).

This HiRISE image shows a portion of interior layered deposits (ILD) in Juventae Chasma. Juventae Chasma is a large depression near the equatorial canyon system Valles Marineris.

What triggered a Martian landslide? Landslides are common features in canyons on both Earth and Mars, and they happen the same way.

A comparison of two radargrams from the SHARAD instrument on NASA's Mars Reconnaissance Orbiter shows effects on the Martian ionosphere from the close passage of a comet.
