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.
