Storm Chaser on Mars

This graphic shows the ongoing contributions of NASA’s rovers and orbiters during a Martian dust storm that began on May 30, 2018.

This image, acquired on January 2, 2014, by NASA's Mars Reconnaissance Orbiter, shows dune fields located among canyon wall slopes.

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 darkenin...

This is an image of Gusev Crater taken by the Mars Reconnaissance Orbiter HiRISE camera and is one of the potential landing sites for the Mars 2020 rover.

NASA's InSight spacecraft and its recently deployed Wind and Thermal Shield were imaged on Feb. 4 by the HiRISE camera aboard NASA's Mars Reconnaissance Orbiter.

Eberswalde Crater was one of the four final landing sites considered for the MSL rover. A channel leads into the crater and the lithified remains of a delta, a fan-like feature formed when sediment...

The HiRISE camera on the Mars Reconnaissance Orbiter is the most powerful telescope to have left Earth orbit. HiRISE is capable of some interesting astronomical observations such as this image of J...

This rainbow-colored map shows underground water ice on Mars. Cool colors are closer to the surface than warm colors; black zones indicate areas where a spacecraft would sink into fine dust; the ou...

These two images show Shallow Radar (SHARAD) instrument data from two tracks in a part of Mars' Utopia Planitia region where the orbiting, ground-penetrating radar on NASA's Mars Reconnaissance Orb...

A portion of a trough in the Nili Fossae region of Mars is shown in enhanced color in this image from the High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Or...

The Mars Reconnaissance Orbiter’s Context Camera, which captured the 110,000 images that make up the interactive global mosaic, is especially useful for spotting impact craters like those seen here.

On this map of Mars, areas indicated in green are where spectrometers on spacecraft orbiting Mars have detected clay minerals and areas indicated in blue are where those spectrometers have detected...

The High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter acquired this image of the Opportunity rover on the southwest rim of "Santa Maria" crater on New...

This image shows the quadrangle where NASA's Curiosity rover landed, now called Yellowknife.

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...

In February 2015, NASA's Mars Exploration Rover Opportunity is approaching a cumulative driving distance on Mars equal to the length of a marathon race. This map shows the rover's position relative...

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 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 image acquired on December 26, 2018 by NASAs Mars Reconnaissance Orbiter, shows the hills that resulted from uplifted rocks due to an impact that formed the 230-kilometer diameter Galle Crater.

This map shows the route driven by NASA's Curiosity Mars rover from the "Bradbury Landing" location where it landed in August 2012 (the start of the line in upper right) to a major waypoint called ...

There are steep scarps facing the poles of both hemispheres that expose thick (up to 100 meters or more) sections of nearly pure water ice.

This composite graphic illustrates the use of the Shallow Radar instrument on NASA's Mars Reconnaissance Orbiter for mapping underground ice-rich layers of the north polar layered terrain on Mars.

This view of layered rocks on the floor of McLaughlin Crater shows sedimentary rocks that contain spectroscopic evidence for minerals formed through interaction with water.

Sand dunes often accumulate in the floors of craters. In this region of Lyot Crater, NASA's Mars Reconnaissance Orbiter (MRO) shows a field of classic barchan dunes on Jan. 24, 2018.
