Martian Winds Give Opportunity Rover Big Power Boost Atop Red Planet Mountain Science Goldmine

NASA’s Opportunity rover was imaged here from Mars orbit by the MRO HiRISE camera on Feb. 14, 2014. This mosaic shows Opportunity’s view while looking back to vast Endeavour crater from atop Murray Ridge by summit of Solander Point. Opportunity captured this photomosaic view on Feb. 16, 2014, (Sol 3579) from the western rim [...]
