The planet Mars shares many landforms and weather patterns with the Earth, including changing seasons, volcanoes, canyons, dust storms and dust devils, and water ice. But one feature that Earth and Mars share among the eight planets in our solar system are polar ice caps. Both are one of each planet’s striking features, but the major difference is while Earth’s polar ice caps are both comprised of water, Mars’ north polar ice cap is only compris…
The comparison of long-term orbital images shows that light ice deposits at 32 out of 36 crater sites studied have changed near the Martian North Pole. The extent to which they grow or shrink seems to be closely related to the frost conditions in their surroundings. The changes thus provide new clues to the water cycle of the polar region, but not yet a balance sheet for the entire ice cap. [...] The article Ice in polar Mars craters changes fro…
A recent study revealed new information about seasonal changes in the ice of the polar craters of Mars, focusing on the dynamics of ice in the northern polar cap of the planet.
