Animation of MAVEN orbiting Mars

Energetic particles from a large solar storm in September 2017 were seen both in Mars orbit by NASA's MAVEN orbiter, and on the surface of Mars by NASA's Curiosity Mars rover.

This ultraviolet image near Mars’ South Pole was taken by MAVEN on July 10 2016 and shows the atmosphere and surface during southern spring.

This graphic depicts the relative shapes and distances from Mars for five active orbiter missions plus the planet's two natural satellites. It illustrates the potential for intersections of the spa...

The Solar Energetic Particle (SEP) instrument is part of the Particles and Fields (P & F) Package and determines the impact of SEPs on the upper atmosphere.

The Magnetometer (MAG) is a part of the Particles and Fields (P & F) Package and measures interplanetary solar wind and ionospheric magnetic fields.

The Langmuir Probe and Waves (LPW) instrument is part of the Particles and Fields (P & F) Package and determines ionospheric properties and wave heating of escaping ions and solar EUV input to ...

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 MAVEN spacecraft is moved into the Thermal Vacuum Chamber (TVAC) at Lockheed Martin on May 16, 2013.

The payload fairing for the Mars Atmosphere and Volatile Evolution, or MAVEN, spacecraft arrives at the Payload Hazardous Servicing Facility at NASA's Kennedy Space Center in Florida.

The Martian surface bears ample evidence of flowing water in its youth, from crater lakes and riverbeds to minerals that only form in water. But today Mars is cold and dry, and scientists think tha...

NASA's MAVEN spacecraft recently completed assembly and has started environmental testing. In the Multipurpose Test Facility clean room at Lockheed Martin, technicians installed the orbiter's two s...

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...

These eight graphs present data from the Neutral Gas and Ion Mass Spectrometer on NASA's MAVEN orbiter identifying ions of different metals added to the Martian atmosphere shortly after comet C/201...

NASA's Mars Atmosphere and Volatile Evolution (MAVEN) spacecraft has obtained its first observations of the extended upper atmosphere surrounding Mars.

This graphic depicts what Mars' atmosphere would have looked like to a viewer with ultraviolet-seeing eyes after a meteor shower on Oct. 19, 2014. It combines an image from the Imaging Ultraviolet ...

Artist's conception of the complex magnetic field environment at Mars. Yellow lines represent magnetic field lines from the Sun carried by the solar wind, blue lines represent Martian surface magne...
