Abstract: A vast diversity of environments exists within and beyond Earth. To the extent life depends on and interacts materially with its environment, it can be expected that life-hosting potential among these environments varies as much as the physical and chemical properties that define them. To understand this potential demands that we first understand lifes requirements in some detail. Discussion of these requirements is frequently undertaken in considering habitability. Cockell et al. (2016) argue that the term habitability is inherently binary: An environment either can or cannot sustain life. This is an important starting point in evaluating the life-hosting potential of…
