Curious Mars

Mars: July 2019

Ancient hydrology is recorded by sedimentary rocks on Mars. The most voluminous sedimentary rocks that formed during Mars' Hesperian period are sulfate-rich rocks, explored by the Opportunity rover from 2004-2012 and soon to be investigated by the Curiosity rover at Gale crater.

This paper presents a case study of microbe transportation in the Mars-satellites system. We examined the spatial distribution of potential impact-transported microbes on the Martian moons using impact physics by following a companion study (Fujita et al.).

The processes behind the release and consumption of methane on Mars have been discussed since methane was measured for the first time for approx. 15 years ago.
