After a final attempt last week, NASA has stopped trying to make contact with the Mars rover called Spirit, which was last heard from in March 2010 as the Martian winter was setting in. Hopes of hearing more from Spirit were slim even then, but there is a difference between not hearing and no longer listening. Spirit was a spectacular success. A three-month mission, beginning in 2004, turned into six years of exploration. Even the accidents were profitable. When Spirit bogged down, permanently, at a location called Troy, efforts to free it revealed unexpected subsurface sulfates, which scientists believe are part of the Mars water cycle.
