The original mission was scheduled to last 90 Martian days, but that estimate has proved to be far short of the rovers' capabilities. A Martian day lasts 24 hours and 37 minutes of Earth time while a Martian year lasts 686.98 Earth days.
Opportunity traveled almost five miles over nearly three Earth years before it arrived at Victoria Crater and took this photo (left) of a rock outcropping named Cape Verde.
