Animation of MAVEN orbiting Mars

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 ...

The MAVEN spacecraft core structure is successfully lowered and mated to the hydrazine propulsion tank and boat tail assembly at Lockheed Martin, Denver.

This infographic shows the various sources of carbon dioxide on Mars and their estimated contribution to Martian atmospheric pressure.

Comet Siding Spring is about to fly historically close to Mars. The encounter could spark Martian auroras, a meteor shower, and other unpredictable effects. Whatever happens, NASA's fleet of Mars s...

NASA is preparing to launch a spacecraft to study the upper atmosphere of the planet Mars. It's called MAVEN or the Mars Atmosphere and Volatile EvolutioN.

Members of the Mars Atmosphere and Volatile Evolution (MAVEN) team celebrate at the Lockheed Martin operations center in Littleton, Colorado, Sunday night, after getting confirmation that the space...

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.

This is an image of the ultraviolet “nightglow” in the Martian atmosphere over the south pole. Green and white false colors represent the intensity of ultraviolet light, with white being the bright...

Billions of years ago when the Red Planet was young, it appears to have had a thick atmosphere that was warm enough to support oceans of liquid water - a critical ingredient for life. (Audio: music...

NASA's MAVEN spacecraft measured light and heavy isotopes of argon in the Martian atmosphere, allowing scientists to determine that the majority of the planet's air was lost to space.

The engineering model of the Extreme Ultraviolet (EUV) sensor that is part of the Langmuir Probe and Waves (LPW)/EUV experiment on MAVEN and will measure the solar EUV input to the atmosphere.

To receive the same amount of starlight as Mars receives from our Sun, a planet orbiting an M-type red dwarf would have to be positioned much closer to its star than Mercury is to the Sun. 

In the Launch Control Center at Cape Canaveral Air Force Station in Florida, agency and contractor managers and engineers monitor progress in the countdown to launch the Mars Atmosphere and Volatil...

NASA's next mission to Mars will carry a DVD containing over 1,100 entries selected as a result of the University of Colorado at Boulder's Laboratory for Atmospheric and Space Physics Going to Mars...

MAVEN's Imaging UltraViolet Spectrograph obtained this image of Mars on July 13, 2016, when the planet appeared nearly full when viewed from the highest altitudes in the MAVEN orbit.

How did Mars, a once wet planet, lose its early atmosphere? One possibility is through a process called "sputtering," in which atoms are knocked away from the atmosphere due to impacts with energet...
