This image, combining data from two instruments aboard NASA's Mars Global Surveyor, depicts an orbital view of the north polar region of Mars. The ice-rich polar cap (the quasi-circular white area at ...

Mars has never looked more like a world in transition, with ice emerging as the quiet architect of its past and a crucial resource for its future. A new wave of NASA data is sharpening the picture of ...

Changes in Mars’ axial tilt (obliquity) drive shifts between polar ice caps at low obliquity and widespread mid-latitude glaciation at high obliquity. These cycles result in ice accumulating inside ...

An artist's impression of the Mars Express spacecraft probing the southern hemisphere of the planet. Using a satellite to peer beneath layers of dust and ice at Mars’ south pole, scientists have ...

Advances in technology have reopened the debate over terraforming Mars, shifting it from an impossible dream to a long-term scientific and ethical question.

Mars is tantalizingly similar to Earth in many ways, but especially in its surface features, which often resemble Earth deserts to an eerie degree. Both Earth and Mars share features such as valleys; ...

Oklahomans might have had little nice to say about ice when they were slipping and sliding around last week. But when it concerns Mars, ice is nice. A recent study detailed in Science magazine show ...

UNIVERSITY PARK, Pa. — Frozen in time, ancient microbes or their remains could be found in Martian ice deposits during future missions to the Red Planet. By recreating Mars-like conditions in the lab, ...

Using a satellite to peer beneath layers of dust and ice at Mars’ south pole, scientists have detected a 12-mile-wide span of briny water, a large, stable reservoir akin to lakes buried beneath the ...
