It is clear that water on Mars, such as oceans and rivers, were prominent features of Mars billions of years ago. The big question is where did all of this water go. Mars is much smaller then earth and therefore has a thinner atmosphere and less gravity. As water evaporated from these prehistoric oceans and rivers on Mars, much of it escaped in to space, meaning that less and less of it fell back on Mars’ surface thus reducing the amount of
