This image show a fan-shaped deposit where a channel enters a crater. This suggests that water once flowed through the channel into a crater lake, depositing material in a similar manner to river d...

This image from NASA's Mars Reconnaissance Orbiter (MRO) shows the permanent polar cap of Mars, encircled by sand dunes and looking like pulled threads. These dunes march across a fabric of pattern...

This is the 3-D anaglyph showing a microscopic image taken of soil featuring round, blueberry-shaped rock formations on the crater floor at Meridiani Planum, Mars. This image was taken on the 13th ...

Engineers install the SuperCam instrument on Mars 2020's rover. This image was taken on June 25, 2019, in the Spacecraft Assembly Facility at NASA's Jet Propulsion Laboratory, Pasadena, California.

This color view of a mineral vein called "Homestake" comes from the panoramic camera (Pancam) on NASA's Mars Exploration Rover Opportunity.

NASA and the European Space Agency are developing plans for one of the most ambitious campaigns ever attempted in space: bringing the first samples of Mars material safely back to Earth for detaile...

These three views of the Martian moon Phobos were taken by NASA's 2001 Mars Odyssey orbiter using its infrared camera, THEMIS. Each color represents a different temperature range.

A proposed helicopter could triple the distances that Mars rovers can drive in a Martian day and help pinpoint interesting targets for study.

These images show changes in the dust accumulation over the course of four days on the rim of the collection tube containing Perseverance’s 14th sample. The images were acquired on Oct. 22, Oct. 26...

The long, sinuous raised ridges on this fan of material are thought to be inverted stream channels. These ridges may have been low-lying streambeds that hardened and then turned into ridges when th...

Researchers used the panoramic camera (Pancam) on NASA's Mars Exploration Rover Opportunity to capture this view of comet C/2013 A1 Siding Spring as it passed near Mars on Oct. 19, 2014.

Side-by-side images depict NASA's Curiosity rover (left) and a moon buggy driven during the Apollo 16 mission.

How does a rover keep driving on a planet with no gas stations? Shonte Tucker, Sabah Bux and Rob Manning power us through the ways Mars rovers keep going.

Faire atterrir une sonde sur Mars est l’une des choses les plus complexes à réaliser. Cette vidéo de 60 secondes explique comment cela est possible, et illustre les trois systèmes d'atterrissage ut...

The electricity for NASA's Mars 2020 rover is provided by a power system called a Multi-Mission Radioisotope Thermoelectric Generator, or MMRTG. The MMRTG will be inserted into the aft end of the r...

Rover 2 is driven over staggered ramps to test the suspension's range of motion.

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 blink comparison aids evaluation of a drive by NASA's Mars Exploration Rover Spirit during the rover's 2,099th Martian day, or sol (Nov. 28, 2009).

NASA's InSight arrives at Vandenberg AFB and readies for launch, Opportunity uses its abrasion tool for the first time in 300 sols, and Curiosity celebrates 2,000 Martian days on the Red Planet.

NASA Associate Administrator for Science Thomas Zurbuchen addressed the Opportunity rover team inside Mission Control at NASA’s Jet Propulsion Laboratory in Pasadena, California, a few hours before...

As Opportunity crept farther into "Endurance Crater," the dune field on the crater floor appeared even more dramatic.

Members of the NASA Mars Helicopter team inspect the flight model (the actual vehicle going to the Red Planet), inside the Space Simulator.
