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 ...

Are researchers searching in the wrong locations on Mars to find ancient life? This is what a recent study published in Astrobiology hopes to address as a team of researchers investigated searching in ...

Mars today is a cold, dry desert, but its surface tells a very different story. Ancient river channels, lake basins, and ...

In a recent study, a team of researchers from NASA Goddard Space Flight Center and Penn State suggested that future missions to Mars search for microbes or their remains in that planet’s ice, rather ...

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

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, ...

On the flanks of Martian mountains and crater rims, curious shapes sprawl outward like thick syrup frozen mid-flow. But these are not rivers of rock or lava. They’re massive glaciers, hidden under ...
