Home This image shows a 3D model of a carbonate molecule next to a 3D model of an oxalate molecule. The carbonate is made of a carbon atom that’s bonded with three oxygen atoms. The oxalate is made of two carbon atoms bonded with four oxygen atoms.

This graphic depicts paths by which carbon has been exchanged among Martian interior, surface rocks, polar caps, waters and atmosphere, and it also depicts a mechanism by which it is lost from the atmosphere. (Lance Hayashida/Caltech)
