MAVEN Solar Panel

This image is a stereo, panoramic view of various trenches dug by NASA's Phoenix Mars Lander. The images that make up this panorama were taken by Phoenix's Surface Stereo Imager at about 4 p.m., lo...

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

This graphic depicts paths by which carbon has been exchanged among Martian interior, surface rocks, polar caps, waters and atmosphere, and also depicts a mechanism by which it is lost from the atm...

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. 

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...

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.

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

The MAVEN Solar Wind Ion Analyzer will study ions in the Martian atmosphere, a key component for better understanding the planet's evolution.

NASA’s Mars Atmosphere and Volatiles Evolution (MAVEN) spacecraft is seen inside the Payload Hazardous Servicing Facility on Aug. 3. 2013 at the agency’s Kennedy Space Center in Florida.

Computer-generated visualization of the orbital paths (white dots) taken by the MAVEN spacecraft as it mapped winds (blue lines) in the Martian upper atmosphere.

MAVEN will use its Neutral Gas and Ion Mass Spectrometer to study the interaction of neutral gases and ions in the Martian atmosphere with the solar wind, helping scientists to understand how Mars ...

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...

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...

The United Launch Alliance Atlas V rocket lifts off from Space Launch Complex-41 at Cape Canaveral Air Force Station carrying the Mars Atmosphere and Volatile Evolution, or MAVEN, spacecraft on a 1...

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...

Artist’s conception of MAVEN’s Imaging UltraViolet Spectrograph (IUVS) observing the “Christmas Lights Aurora" on Mars. MAVEN observations show that aurora on Mars is similar to Earth’s "Northern L...

The United Launch Alliance Atlas V rocket stands at Launch Complex 41 on Cape Canaveral Air Force Station in Florida during a "wet dress rehearsal."

MAVEN will use a Propellant Management Device (PMD), which is a static, all-metal structure inside the fuel tank that uses surface tension to ensure gas free liquid delivery to the tank outlet.

Engineers work on the MAVEN spacecraft, which is dominated by the high-gain antenna that is crucial to communications with NASA's Deep Space Network.

NASA's MAVEN mission is observing the upper atmosphere of Mars to help understand climate change on the planet. MAVEN entered its science phase on Nov. 16, 2014.

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 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.
