The Mars Exploration Rovers are wrapping up another year of exploring their seventh -- having experienced both the best of times and the worst of times: Spirit continued a 10-month struggle to endure its coldest, harshest Martian winter yet; Opportunity set a new record for driving despite an arthritic front wheel and a broken shoulder, putting more miles on her rocker bogie in 2010 than in any other single year.
