This full-resolution Compact Reconnaissance Imaging Spectrometer for Mars (CRISM) “targeted image” shows the edge of Mars’ north polar cap. The featured region, Chasma Boreale, is a valley several ...

The ice-rich polar cap (the quasi-circular white area at center) is approximately 621 miles (1,000 kilometers) across. The white cap is riven with dark, spiral-shaped bands. These are deep troughs ...

This is Mars, captured in all of its stunning glory over the years by an assortment of high powered telescopes, deep space probes and autonomous rovers. Water-ice clouds, polar ice, polar regions, and ...

Scientists have reconstructed the formation of two curious features in the northern ice cap of Mars—a chasm larger than the Grand Canyon and a series of spiral troughs—solving a pair of mysteries ...

The Chasma Boreale, seen above, is about 350 miles long, cutting deep into the north polar icecap of Mars. With walls rising nearly one mile above the floor and ending at the edge of the retreating ...

A bulletin from Daniel Stolte of UA Communications: A team of planetary scientists has used radar and a high-resolution camera to reveal the subsurface geology of Mars’ northern ice cap. The findings ...

Chasma Boreale, a long, flat-floored valley, cuts deep into Mars’ north polar icecap. Its walls rise about 4,600 feet, or 1,400 meters, above the floor. Where the edge of the ice cap has retreated, ...

The Mars Reconnaissance Orbiter's HiRISE camera captured this intriguing image of a field of stunning dunes known as barchan dunes, as reported first by Universe Today. These dunes were captured in ...
