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 sequence of images shows a blast zone where the sky crane from NASA's Curiosity rover mission hit the ground after setting the rover down in August 2012, and how that dark scar's appearance ch...

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

With the Compact Reconnaissance Imaging Spectrometer for Mars (CRISM) instrument just above his head, a technician at NASA’s Kennedy Space Center works on the Mars Reconnaissance Orbiter spacecraft...

This anaglyph from HiRISE shows erosional features formed by seasonal frost near the south pole of Mars.

This HiRISE image shows diverse layers in a region near Mawrth Vallis, a channel that was probably carved by water in Mars' ancient past. The color subimage shows details of layers exposed in a cra...

This sequence of images shows a blast zone where the sky crane from NASA's Curiosity rover mission hit the ground after setting the rover down in August 2012, and how that dark scar's appearance ch...

This March 20, 2014, image from the MARCI camera on NASA's Mars Reconnaissance Orbiter has a dark spot (at center of inscribed rectangle) noticed while the image was being examined for a weather re...

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 enhanced-color image shows sand dunes trapped in an impact crater in Noachis Terra, Mars.

This image (top) taken by the Shallow Radar instrument on NASA's Mars Reconnaissance Orbiter reveals the layers of ice, sand and dust that make up the north polar ice cap on Mars

This map shows the route driven by NASA's Curiosity Mars rover from the location where it landed in August 2012 to its location in September 2016 at "Murray Buttes," and the path planned for reachi...

A rippled dune front in Herschel Crater on Mars moved an average of about two meters (about two yards) between March 3, 2007 and December 1, 2010, as seen in these images from NASA's Mars Reconnais...

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 ...

HiRISE captured this image of an eroded mesa made famous by its similarity to a human face in a Viking Orbiter image with much lower spatial resolution and a different lighting geometry.

The Cerberus Fossae are a group of troughs in the Cerberus region of Mars that run roughly parallel to one another. They formed due to extension of the crust in the region. Some of the troughs, suc...

NASA’s InSight has been busy. After landing on the Red Planet, the mission sent home pictures and sound, then placed its first instrument on the planet's surface. Plus, find out what the Curiosity ...

This image acquired on November 30, 2018 by NASAs Mars Reconnaissance Orbiter, shows a complex crater, where we see bedrock in several locations from different depths in the crust.

These color-enhanced views of Deimos, the smaller of the two moons of Mars, were taken by the High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter.

This picture of a crater resembling a "happy face" was taken by the Mars Reconnaissance Orbiter's Context Camera. The unnamed crater is almost 2 miles (about 3 kilometers) across That's a BIG smile!

This graphic depicts the Mars Climate Sounder instrument on NASA's Mars Reconnaissance Orbiter measuring the temperature of a cross section of the Martian atmosphere as the orbiter passes above the...

Lucus Planum is a part of the enigmatic Medusa Fossae Formation, a broad, soft, and easily eroded deposit. Here this deposit is thin and considerably rougher than elsewhere, implying that it is hea...

This animation simulates a flyover of a portion of a Martian canyon detailed in a geological map produced by the U.S. Geological Survey and based on observations by NASA's Mars Reconnaissance Orbit...

These examples of one distinctive type of Martian gullies, called "linear gullies," are on a dune in Matara Crater, seen at different times of year to observe changes.

This animation depicts a flyover of a meteoroid impact crater on Mars that’s surrounded by boulder-size chunks of ice. The animation was created using data from the High-Resolution Imaging Science ...
