Coinciding with ten years of the NASA Mars Exploration Rover
Project, research published today in Science has found some of the oldest
evidence of past water on Mars – and confirmed it was ideal to nurture life.
Found in ancient mudstones at Mars’ Endeavour Crater, the
geochemical data collected by the Opportunity Rover shows that water was almost
fresh. It would have been, almost four billion years ago, the most liveable mud
on Mars.
