Forgotten rovers

With Pluto not being a planet, SMART-1 crashing into the moon and the latest shuttle mission gearing up, don’t forget about these little guys. Originally guaranteed for 90 days, Spirit and Opportunity have notched up around 950 and 930 Martian sols, respectively and are still going strong. In that time, they’ve travelled between just seven to nine kilometres! Opportunity is now just 200 metres or so from Victoria Crater, a deep, wide crater with at least 30-40 m of exposed bedrock to examine. The rock was spotted by another forgotten craft – Mars Global Surveyor, now the oldest active craft at Mars with 3284 days (9 years on September 12) in orbit.
