Opportunity approaches the 'Twin Craters,' sol 2191
Opportunity approaches the 'Twin Craters,' sol 2191 As of sol 2191 (March 23, 2010), only two weeks after departing Concepción crater, Opportunity had drawn within about 120 meters of a doublet crater. The shape of the double crater indicates that it was likely formed in a single impact event by a body that split into two pieces as it was falling through Mars' atmosphere.
