"The NASA Mars Exploration Rover Opportunity is beginning its 10th year roving Mars, completing nine years of "shocking" performance and historic discoveries that began with a bouncing airbag roll into tiny Eagle crater on Jan. 24, 2004."
"It's amazing, we never expected these kind of results!", says Pete Theisinger, the original MER project manager at the Jet Propulsion Laboratory in Pasadena. Calif. He also led JPL's Curiosity rover development in the same role."
