From Viking 1’s first close-up in 1976 to today’s breathtaking views captured by HiRISE, Curiosity, Perseverance, Ingenuity, ...

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

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 ...

Until recently, Mars was studied only through telescopes and some data that was recorded from early spacecraft. It was thought that Mars' polar regions were the only significant reservoirs of ice, ...

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 ...

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 ...

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

Scientists have found that ancient Martian lakes could have survived for decades despite freezing air temperatures. Using a newly adapted climate model, researchers showed that thin, seasonal ice ...

A schematic of temperature measurements shows how it is 40 degrees Celsius colder inside the north polar vortex (indicated by the yellow line) compared to outside the vortex. A rare glimpse into the ...
