Exposure to sunlight creates telltale patterns in the polar ice cap that change over time, potentially providing insight into the climatic history of the Red Planet.
Ice avalanches may have traveled at speeds of up to 80 meters per second.
A new study ties layers in the polar deposits of Mars to changes in climate driven by orbital variations, constraining accumulation rates and further deciphering the climate history of the Red Planet.
Laboratory experiments that indicate rock particles can impede sliding along grain boundaries in ice may help researchers more accurately determine the composition of planetary ice masses.

Shallow Radar correlation of discrete units in one of the Red Planet’s largest ice reservoirs suggests that its material was emplaced as a single, regional deposit.
New radar observations and refined illumination maps reveal uneven water ice deposits twice the size of those found around the planet’s north pole, suggesting the source may be a recent comet impact.
Orbital wobbling shaped the dome of ice and dust at the planet's north pole.
