Figure 1: Diagram of the scientific equipment on MER-B Opportunity Mars Exploration Rover Launches Press Kit, June 2003, p. 41 [i] I mentioned in a blog last week that Mars Exploration Rover B (FIgure 1), more affectionately called Opportunity, recently celebrated the 12th anniversary (in Earth years) of its landing on Mars.  12 years without maintenance on the hostile surface of another planet is incredible, considering the original operational time was planned for only 3 months.  Mars Science Laboratory Curiosity currently gets the most press, with its larger tool library and fancier cameras, but there are still scientists and engineers at JPL piloting Opportunity from one scientific site to the next.  In the last blog, I mentioned [...]
