Countdown Nears: Final Tests

This image reveals exposed layers in Noctis Labyrinthus which may contain signatures of iron bearing sulfates and phyllosilcate (clay) minerals.

This image of Santa Maria Crater was taken by the High Resolution Imaging Science Experiment (HiRISE) camera on Mars Reconnaissance Orbiter.

The bright feature in this image might be the parachute from a 1971 Soviet Mars lander named Mars 3. The image was taken by the High Resolution Imaging Science Experiment (HiRISE) camera on NASA's...

Planum Australe Region

NASA's Curiosity Mars rover used its Navigation Camera (Navcam) on April 11, 2014, to record this scene of a butte called "Mount Remarkable" and surrounding outcrops at a waypoint called "the Kimbe...

This map shows the thickness of the north polar layered deposits on Mars as measured by the Shallow Radar instrument on NASA's Mars Reconnaissance Orbiter.

This image covers a location that has been imaged several times to look for changes in gullies.

This image contrasts gullies and recurring warm-season slope flows appearing in the same crater, in the middle southern latitudes of Mars.

This image acquired on December 5, 2018 by NASAs Mars Reconnaissance Orbiter, shows ripples in the sand which tell us which way the wind was moving and how it was diverted around these rock formati...

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...

This image acquired on January 20, 2019 by NASAs Mars Reconnaissance Orbiter, shows a chaotic jumble of bright layered sediments, perhaps resulting from large landslides.

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 est...

The Mars Color Imager test view looks northward and includes the large Argyre Basin in Mars' southern hemisphere.

NASA's Mars Reconnaissance Orbiter passes above a portion of the planet called Nilosyrtis Mensae in this artist's concept illustration.

The colorful rocks exposed in the central peak visible in this image probably reflect variations in mineral content that were caused by water activity early in Mars' history. The CRISM hyperspectra...

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...

The High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter snapped this series of false-color pictures of sand dunes in the north polar region of Mars.

This image shows layered blocks tilted at high angles, diverse color and textures and dark dunes. Some of the bedrock may have originated at great depths, uplifted first by Becquerel Crater and lat...

Back-and-forth blinking of this two-image animation shows movement of a sand dune on Mars. The images are part of a study published by Nature on May 9, 2012, reporting movement of Martian sand dune...

The bright linear features cutting the bedrock in the center region of this image look like mineral veins.

Crater in Thaumasia Fossae

This 3D, or stereo anaglyph, view shows the upcoming science destination for NASA's Mars rover Curiosity, a region dubbed "Glenelg," where three different types of material seen from orbit come tog...

Well-Preserved Crater with Central Peak in Chryse Planitia

These images show a 256 x 256 pixel patch of sky at the range to the comet of 8 million miles and when the solar phase angle is 47 degrees.

This map shows the route on lower Mount Sharp that NASA's Curiosity followed between April 19, 2015, and Nov. 5, 2015. During this period the mission investigated silica-rich rock targets includin...
