Biogeochemistry, Planetary Protection, and Astromaterials Curation: A Story of Environmental Microbiology at NASA

The astromaterials curation office at the NASA Johnson Space Center is responsible for curating and allocating all of the extraterrestrial samples collected by NASA. This includes lunar samples, meteorites, cometary material, asteroid samples and individual atoms of the solar wind. Some of these collections are susceptible to biological alteration by terrestrial microbes. I will describe the microbial monitoring of the clean rooms used to store these samples and the ecology we find therein. This research is helping NASA design better cleanrooms for even more sensitive samples like those currently being collected on Mars. I will also discuss our group’s research on improved identification methods, biological alteration of meteorites, and efforts to sample microbes on the outside of the International Space Station.
