NASA's MAVEN (Mars Atmosphere and Volatile EvolutioN) spacecraft, inside a payload fairing, is hoisted to the top of a United Launch Alliance Atlas V rocket at the Vertical Integration Facility at ...

Mars presents intriguing questions to scientists: How did the Red Planet become so desolate? Did Mars once look like Earth? How has it changed? The Mars Atmosphere and Volatile Evolution Mission (M...

This is an artist rendition of NASA"s Mars Atmosphere and Volatile Evolution, or MAVEN spacecraft orbiting Mars.

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.

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...

Ultraviolet images from NASA's Mars Atmosphere and Volatile Evolution mission, MAVEN, were used to make this movie of rapid cloud formation on Mars.

NASA's MAVEN spacecraft underwent acoustics testing on Feb. 13, 2013 at Lockheed Martin Space Systems' Reverberant Acoustic Laboratory.

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...

Inside the Payload Hazardous Servicing Facility at NASA's Kennedy Space Center in Florida, engineers and technicians prepare the Mars Atmosphere and Volatile Evolution, or MAVEN, spacecraft for enc...

Artist’s concept of Comet Siding Spring approaching Mars, shown with NASA’s orbiters preparing to make science observations of this unique encounter.

MAVEN observations of a proton aurora. In the top panel, natural variability of the solar wind results in occasional dense flows of solar wind protons bombarding Mars. 

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 ...

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

This graph shows how the amount of water in the atmosphere of Mars varies depending on the season.

MAVEN positioned atop Atlas V rocket.

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. 

Mars was once on track to become a thriving Earth-like planet, yet today it is an apparently lifeless wasteland. A NASA spacecraft named MAVEN will soon journey to Mars to find out what went wrong ...

The MAVEN Electra UHF Transceiver Flight Model is shown here.

At Cape Canaveral Air Force Station in Florida, the United Launch Alliance Centaur second stage is lifted for stacking atop its Atlas V first stage at Launch Pad 41 in preparation for the Mars Atmo...

This artist's concept depicts the early Martian environment (right) - believed to contain liquid water and a thicker atmosphere - versus the cold, dry environment seen at Mars today (left).

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...

Two days before the scheduled launch to Mars, the United Launch Alliance Atlas V rocket and NASA's Mars Atmosphere and Volatile Evolution (MAVEN) spacecraft rolled out of the Cape Canaveral Air For...

Following liftoff of the Mars Atmosphere and Volatile Evolution, or MAVEN, spacecraft from Cape Canaveral Air Force Station, NASA Administrator Charles Bolden congratulated the agency and contracto...

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