Q: If the RTG (radioisotope thermoelectric generator) can generate power for about 14 years, what were the limiting factors driving the 2 year mission estimate? What components might fail first?
A: The length of the mission is currently set for 23 months to achieve mission success, but it could be extended just like the Mars Exploration Rovers. They had a prime mission of 90 days but Opportunity is still operating over 8 years later. -VM
