ESA announcement of opportunity for NASA MARS 2020 returned sample science - Participating Scientist
This Returned Sample Science Participating Scientist (RSS PS) AO of ESA seeks individuals whose addition to the mission's science team will enhance the value of the samples to be selected, characterized, and cached by the NASA Mars 2020 Rover. The selected investigators should anticipate the needs of future investigators who may analyse these samples for a very diverse range of studies in Earth‐based laboratories. Selected RSS PSs are expected to contribute collaboratively to any and all aspects of the surface science mission.

Deadline for mandatory LOI submission: 15 April 2020
Deadline for proposal submission, including letter of endorsement of financial support: 30 April 2020

NASA Astrobiology Program FAQs
The NASA Astrobiology Program has announced a new programmatic infrastructure. Known as Research Coordination Networks (RCNs), and first deployed as the Nexus for Exoplanet System Science (NExSS), RCNs bring together researchers who are funded from a variety of sources into interdisciplinary, topically-focused research groups. By early 2020, the NASA Astrobiology Program will have activated five RCNs -- four new ones plus NExSS -- each organized around a key research topic identified in the 2015 Astrobiology Strategy: prebiotic chemistry and the early Earth; early metabolism, evolution, and complexity; life detection on other worlds; habitable worlds (initially focused on ocean worlds); and exoplanet system science.

This document contains answers to Frequently Asked Questions about the Astrobiology Program organized by topical areas.

Heller (2020): Habitability is a continuous property of nature

Response to "Habitability is a binary property" by Charles S. Cockell, Adam H. Stevens and R. Prescott

Nature Astronomy 2019, 3, 956–957, DOI:10.1038/s41550-019-0916-7

In their recent Comment, Cockell et al. argue that the habitability of an environment is fundamentally a binary property; that is to say, an environment can either support the metabolic processes of a given organism or not. The habitability of different environments, they argue, may have different degrees that could be determined at least in theory by answering the question: 'is this environment habitable to a given organism?' 'More' or 'less' habitable environments could then be related by the number of yes or no answers given to what is fundamentally a series of binary questions and decisions.
