5 Years on Mars Trailer

NASA rovers Spirit and Opportunity may still have big achievements ahead as they approach the fifth anniversaries of their memorable landings on Mars.

Spirit landed safely on Jan. 3, 2004, and Opportunity followed suit three weeks later. The twin rovers have worked 20 times longer than their expected warranties and made important discoveries about wet and tumultuous
environments on Mars.
