  Partial funding for this research was provided by the NASA Astrobiology Institute. The NASA Astrobiology Institute, founded in 1997, is a partnership between NASA, 16 major U.S. teams and five international consortia. NAI's goal is to promote, conduct, and lead integrated multidisciplinary astrobiology research and to train a new generation of astrobiology researchers.
