{{quote|Finding evidence of extant life on Mars would be a watershed event. We have evidence on Mars for many environments that may have been habitable in the past, but the range of possible biogeochemistries those environments allow, the co-evolution of those environments with life, the specific niches that are most likely to host detectable biosignatures, and the path forward to explore those environments are still key unknowns. We invite contributions that (1) explore the succession of physical and environmental processes and their combination on Early Mars, (2) evaluate (ideally quantitatively!) the geo/environmental context of potential sites for biological exploration of Mars, (3) detail the most promising locations, instrument concepts, and strategies for investigating these ecosystems, (4) define the relevant objects, substances or patterns that could serve as definitive biosignatures for martian life, and (5) investigate metabolisms, survival strategies, and energy sources that may be relevant to the search for biosignatures on Mars.}}

There were two main topics,
{{quote|Recent discoveries on Mars, including recurring slope lineae, ground ice, and active gully formation, have been interpreted as indications for the transient presence of water. The potential for liquid water on Mars has profound implications for the habitability of the modern Mars environment. This session solicits papers that examine the evidence for habitable environments on Mars, present results about life in analogs to these environments, discuss hypotheses to explain the active processes, evaluate issues for planetary protection, and explore the implications for future explorations of Mars.}}▼
