Working Group on Finding Signs of Past Rock-Hosted Life

Motivated by the suite of habitable environments available to Mars-2020 for in situ exploration and sample collection, we are convening a set of 4 web-hosted telecons, open to the community. The first two telecons are

Telecon 1: Martian Environment: Evidence for Rock-Hosted Waters
What is the evidence for ancient Mars environmental conditions? What is the likelihood of habitats for rock-hosted life?

Telecon 2: Metabolisms and Niches for Terrestrial Rock-Hosted Life
Where rock-hosted life found on earth today? What are its metabolisms and products?
December 20, 8:30AM PST // facilitated by Tullis Onstott, Jeff Marlow
