Opportunity Runs the First Martian Marathon
Mars rover Opportunity is on track to complete the first extraterrestrial marathon.
A marathon is 26.2 miles. When Opportunity landed on Mars in 2004, NASA’s goal was to have the rover travel a meager 600 meters. However, no one knew what kind of “runner” Opportunity would turn out to be. As of July 2012, Opportunity has traveled almost 22 miles – only 4.2 miles short of a full marathon.
