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 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.

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...

MAVEN was launched into a Hohmann Transfer Orbit with periapsis at Earth’s orbit and apoapsis at the distance of the orbit of Mars. The spacecraft will travel more than 180 degrees around the Sun i...

For optimal performance, it’s important for the high-gain antenna to maintain a consistent temperature while the spacecraft experiences large temperature swings from being exposed to the Sun or in ...
