Animation of MAVEN orbiting Mars

This radio hardware, the Electra UHF Transceiver on NASA's MAVEN mission to Mars, is designed to provide communication relay support for robots on the surface of Mars.

The Imaging Ultraviolet Spectrograph (IUVS) is a part of the Remote Sensing (RS) Package and measures global characteristics of the upper atmosphere and ionosphere via remote sensing.

The close encounter between comet Siding Spring and Mars flooded the planet with an invisible tide of charged particles from the comet's coma. The dense inner coma reached the surface of the planet...

The places where the red line on this graph extends higher than the blue line show detection of metals added to the Martian atmosphere from dust particles released by a passing comet on Oct. 19, 20...

This artist's concept depicts the Imaging Ultraviolet Spectrograph (IUVS) on NASA's MAVEN spacecraft scanning the upper atmosphere of Mars. IUVS uses limb scans to map the chemical makeup and verti...

On May 1, 2013, followers of the NASA MAVEN mission can begin entering their names to be placed on a specially designed DVD that will accompany the spacecraft on its journey to Mars this November.

This image shows atomic hydrogen scattering sunlight in the upper atmosphere of Mars, as seen by the Imaging Ultraviolet Spectrograph on NASA's Mars Atmosphere and Volatile Evolution mission.

These images from the Imaging Ultraviolet Spectrograph on NASA's MAVEN orbiter show the appearance of a bright aurora on Mars during a solar storm in September 2017. The purple-white colors shows t...

A dust storm continues to envelop the Red Planet and Curiosity’s labs are back in action.

When you navigate with a compass you can orient yourself thanks to Earth's global magnetic field. But on Mars, if you were to walk around with a compass it would haphazardly point from one anomaly ...

The Atlas V rocket carrying the Mars Atmosphere and Volatile Evolution (MAVEN) spacecraft sits at the launch pad at Florida's Cape Canaveral Air Force Station after rolling out from Space Launch Co...

A map of MAVEN's Imaging Ultraviolet Spectrograph (IUVS) auroral detections in December 2014 overlaid on Mars’ surface.

Ancient riverbeds, crater lakes and flood channels all attest to Mars's warm, watery past. So how did the Red Planet evolve from a once hospitable world into the cold, dry desert that we see today?

This animation shows a proton aurora at Mars. First, a solar wind proton approaches Mars at high speed and encounters a cloud of hydrogen surrounding the planet. 

At Cape Canaveral Air Force Station's Space Launch Complex 41 a United Launch Alliance Atlas V rocket stands ready to boost the Mars Atmosphere and Volatile Evolution, or MAVEN, spacecraft on a 10-...

JPL CubeSat clean room is doing big things for space explorations smallest inhabitants.

NASA's Mars Atmosphere and Volatile EvolutioN, or MAVEN, spacecraft, mounted atop a United Launch Alliance Atlas V rocket, rolls out from Cape Canaveral Air Force Station's Vertical Integration Fac...

NASA Goddard hosted a live Google+ Hangout on Wednesday, Nov. 13 at 4 p.m. EST about MAVEN, NASA's next mission to Mars.

At Cape Canaveral Air Force Station's Space Launch Complex-41 liquid oxygen began flowing into the Atlas first stage booster for the Mars Atmosphere and Volatile Evolution, or MAVEN, mission.

This artist's concept shows NASA's Mars orbiters lining up behind the Red Planet for their "duck and cover" maneuver to shield them fro comet dust that may result from the close flyby of comet Sidi...
