About

Jack Farmer is a pioneering astrobiologist whose research bridges planetary science, geology, and the search for life beyond Earth. His key contributions center on understanding the preservation of biosignatures in ancient terrestrial and extraterrestrial environments, particularly through the study of microbial mats, stromatolites, and sedimentary rock records. Farmer’s work has been instrumental in shaping NASA’s exploration strategies for Mars, including the selection of landing sites for the Mars Science Laboratory and the Mars 2020 rover missions. He has also advanced the development of in situ analytical instruments for future lunar and Martian sample-return campaigns, notably through the Lunar Reference Suite, which supports instrument testing for high-grading samples during long-duration missions. With over 1,500 citations across his most impactful publications, Farmer’s research has profoundly influenced how scientists identify and interpret signs of past life on other worlds. His leadership in astrobiology field campaigns and contributions to NASA’s Exobiology program have made him a central figure in the quest to answer whether life exists beyond Earth.
