Description

Recent missions to Mars have provided new evidence that early Mars was at least episodically earth-like with rivers, lakes and possibly oceans, and high rates of aqueous weathering and erosion. Life appears to have arisen early on Earth. Did some form of life start on Mars when conditions on the two planets were similar? Conditions on Mars subsequently changed to become much less hospitable but life, if started, may have maintained a tenuous foothold in isolated niches.
