Animation of MAVEN orbiting Mars

The MAVEN Electra UHF Transceiver Flight Model is shown here.

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.

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

At Cape Canaveral Air Force Station's Space Launch Complex 41, the Mars Atmosphere and Volatile Evolution, or MAVEN, spacecraft is encapsulated atop an Atlas V rocket.

This is an artist's conception of Mars Atmosphere and Volatile Evolution Mission (MAVEN) Mars orbiter.

The MAVEN spacecraft structure is placed into a reaction chamber, where it completed a static loads test to ensure that it will withstand the extreme forces of launch.

This artist's concept shows the MAVEN spacecraft in orbit around the Red Planet, with a fanciful image of her home planet in the background.

This animation shows the sudden appearance of a bright aurora on Mars during a solar storm. The purple-white color scheme shows the intensity of ultraviolet light over the course of the event, from...

The Neutral Gas and Ion Mass Spectrometer (NGIMS) measures the composition and isotopes of thermal neutrals and ions.

These profiles show the brightness of auroras in Mars’ atmosphere at different altitudes. The solid black profile on the right is from a September 2017 solar storm. Barely visible along the vertica...

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...
