 ===Special minerals on Mars===
-'''''(background information):''''' Opportunity discovered manganese oxygens on Mars. These require oxygen to form. Some researchers have suggested they formed in an early Mars atmosphere that was thick and oxygen rich (which doesn't require life; it could for instance be oxygen rich due to ionizing radiation splitting water).

-Their research gives an alternative explanation for the presence of these minerals such as  manganese oxides which require conditions of water and oxygen to form.  This new reseach shows that these minerals could also form without an oxygen rich atmosphere.
+Their research gives an alternative explanation for these minerals, by concentrating the minute traces of oxygen in the atmosphere into the water.
