NASA has taken Spirit off life support. After not hearing any communications from the rover since March 2010, NASA has decided to relocate the resources to a new Mars project. Cian O’Luanaigh of the New Scientist has an obituary for Spirit, the robot geologist, detailing many of its contributions — images of minerals associated with water, temperature sensing, all kinds of rocks and meteorites. Originally planned as a three-month mission that landed on Mars on January 3, 2004, Spirit had a surprisingly long, scientifically rich and successful road. It is survived by its twin Opportunity, which is still operational on Mars.
