Mars Dry Surface

Mars may have seen dry and wet season cycles and thus, may have been habitable at some point in its past, according to scientists. Analysis of mud crack patterns on the early Martian surface, observed by NASA's Curiosity Rover, suggest an irregular or episodic presence of water, meaning water could have been present for a time and then evaporated.

Mars is a primary target in the search for life outside Earth, and liquid water is the most important pre-requisite for life. But a team of international researchers has found that Mars is incredibly dry, and has been that way for millions of years.

A US space agency rover tooling around on the dry surface of Mars has for the first time uncovered direct evidence of what used to be a freshwater lake, scientists said on Monday.
