MAVEN Solar Panel

MAVEN selfie composite, unannotated

This is an artist's model of an early Mars - billions of years ago - which may have had oceans and a thicker atmosphere.

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

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 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 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...

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

The Solar Wind Ion Analyzer (SWIA) is a part of the Particles and Fields (P & F) Package and measures the solar wind and magnetosheath ion density and velocity.

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.

This artist concept depicts NASA’s Space Launch System, which will be the most powerful rocket ever built. It is designed to boost the agency’s Orion spacecraft on deep space missions, including to...

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...

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.

About 1000 Viking Orbiter red- and violet-filter images have been processed to provide global color coverage of Mars at a scale of 1 km/pixel.

This photo taken on March 3 shows the large hydrazine propellant tank prior to integration with the core structure of the MAVEN spacecraft at a Lockheed Martin clean room near Denver.

The MAVEN spacecraft is shown here in testing for Electromagnetic Interference and Electromagnetic Compatibility.

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. 

MAVEN Launching.

This illustration shows the MAVEN spacecraft and the limb of Mars.

This image is from a scientific visualization of the electric currents around Mars.

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.

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...

Inside the Payload Hazardous Servicing Facility at NASA's Kennedy Space Center in Florida, engineers and technicians test deploy the twin solar arrays on the Mars Atmosphere and Volatile Evolution,...

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...

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...
