Opportunity on verge of new discovery

The Mars rover Opportunity, which was designed to operate for three months and to rove less than a mile, has now journeyed more than seven years crossing more than 21 miles. Today, it is poised at the edge of a heavily eroded impact basin, the possible location of clay minerals formed in low-acid wet conditions on the red planet.
