    In this interview, Roger Summons explains how the Curiosity rover’s Sample Analysis at Mars (SAM) instrument is geared to detect organic matter on Mars, and even figure out where it came from. Roger Summons is a geobiologist at the Massachusetts Institute of Technology and member of the SAM team. His research focuses on the preservation and characteristics of organic matter in rocks, and is helping astrobiologists understand how organic matter can carry information about the organisms that formed it.
