While NASA's twin rovers, Spirit and Opportunity, garner all the headlines, the European Space Agency's satellite, Mars Express, is poised to deliver just as much science, including important clues in the hunt for Martian life, at a far lower price. NASA spent more than $800 million on its project, while Mars Express cost a mere €150 million, or about $190 million.
