Second Opportunity For Mars Rover
An anonymous reader writes "The Mars Opportunity rover faces a challenging survey around the rim of the stadium-sized Endurance Crater. In addition to what was previously described as the critical choice to go into the steep crater at the risk of not being able to get back out, this "most spectacular view we've seen of the Martian surface" may aid in answering how deep an ancient sea or lake might have been and how long it lasted. Endurance Crater appears much older and thus may pre-date arrival of significant standing water."
True, but didn't we know that there was history of water on Mars? Just look at any detailed picture of the surface. The markings of liquid are unmistakable. The ice caps are water.
