Huge troughs curving outward from the north pole of Mars like the arms of a pinwheel were not carved into the polar ice caps by some mysterious force, researchers have discovered. Instead, the ...

This is Chasma Boreale on Mars, a flat-floored valley (when seen from above) that is approximately 350 miles long, cuttingly deeply into the Red Planet’s northern polar icecap. The walls of this ...

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 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 ...

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 – based on data from SHARAD (the surface-penetrating ...

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 ...

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 ...

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, ...
