After testing at some of the harshest climates on earth, including the Atacama Desert in Chile, urey, a new sensor for detecting life, has been selected to go to Mars. This instrument will be more powerful than any sent so far, and will be able to detect more sensitively for life on Mars as well as if products were produced by living organisms. Urey is expected to launch in 2013 aboard the European Space Agencies ExoMars rover.
