On August 5, 2012 (PDT), NASA’s Curiosity rover touched down on the Red Planet. Aboard was the Sample Analysis at Mars instrument, or SAM, the most sophisticated chemistry lab ever sent to another planet. Now, on the first anniversary of the landing, engineers at NASA’s Goddard Space Flight Center are using SAM to “sing” Happy Birthday to Curiosity.
