1995 photo of Mars showing approximate size of the polar caps. The planet Mars has two permanent polar ice caps of water ice and some dry ice (frozen carbon dioxide, CO 2).Above kilometer-thick layers of water ice permafrost, slabs of dry ice are deposited during a pole's winter, [1] [2] lying in continuous darkness, causing 25–30% of the atmosphere being deposited annually at either of the ...
Human explorers may be potential carriers back to Earth of microorganisms acquired on Mars, if such microorganisms exist. [45] Another issue is the contamination of the water supply by Earth microorganisms shed by humans in their stools, skin and breath, which could have a direct effect on the long-term human colonization of Mars.

Ice deposits on Mars serve as unique indicators for the climate variability on the Martian surface, due to their status as reservoirs for chemical compounds like carbon dioxide and water. [17] [6] [4] [8] Louth's southerly position of 70 degrees north latitude gives it a unique potential for sensitivity to climatic changes on Mars. [9]
In spring, sublimation of ice causes sand from below the ice layer to form fan-shaped deposits on top of the seasonal ice. [clarification needed] Mars has an axial tilt of 25.2°. This means that there are seasons on Mars, just as on Earth. The eccentricity of Mars' orbit is 0.1, much greater than the Earth's present orbital eccentricity of ...
Such explorers may one day core, sample, and analyze the ice to better understand the record of climatic and geologic change on Mars and its astrobiological potential, which could be revealed through signs of preserved ancient microbial life or even the possibility of living organisms, if Mars ever harbored life. Ice is also a critical natural ...

Research, reported in the journal Science in September 2009, [91] demonstrated that some new craters on Mars show exposed, pure, water ice. After a time, the ice disappears, evaporating into the atmosphere. The ice is only a few feet deep. The ice was confirmed with the Compact Imaging Spectrometer (CRISM) on board the Mars Reconnaissance ...
