What massive geographical feature did Opportunity climb toward during the later phase of its mission?
Answer
Endeavour Crater.
A defining characteristic of Opportunity's extended mission was its methodical, long-distance traverse toward the rim of Endeavour Crater. This feature was deemed highly valuable because its immense size suggested that exploring its rim would expose geological strata significantly older than those observed at Meridiani Planum. By reaching and analyzing the layers exposed on the crater walls, scientists hoped to 'read' older epochs of Martian history, much like examining different pages in a geological book, contrasting the older crust with the younger materials found at the initial landing site.
