NASA | Need To Know: Sample Analysis at Mars Findings

There’s big news coming out of the Sample Analysis at Mars instrument suite (SAM) on NASA’s Curiosity rover. For the first time, organic matter has definitively been detected on Mars. In addition to finding organic compounds in rocks, SAM has also detected sharp increases and decreases in methane levels in the atmosphere. MSL participating scientist, Danny Glavin, explains these findings and what they tell us about our search for life on the Red Planet.
