Sunset at Gusev Crater

 

In 2002 Mars Odyssey's planet wide survey had found hydrogen rich soil near the Martain poles. The only plausible way of storing hydrogen in the quantities that the data suggested is as underground water-ice.

Over Christmas of 2003, the orbiters were joined by an array of international landers and rovers - 'Spirit', 'Opportunity' and 'Beagle 2'. In May 2004, the Opportunity rover found the first direct evidence, in the layered rock sediments, that liquid water once existed at Endurance Crater, enough water to have sustained life as we know it. Later it's ‘twin’ rover ‘'Spirit' found minerals in the rocky basin of Gusev Crater which can only form in the presence of liquid water.
