![Physical and chemical gradients predicted to dictate habitability across depth in the martian subsurface. These include (1) constraints on water; although water activity (aw) gradients are not yet known for Mars, predicted liquid brine stability depends on primary ionic composition with perchlorate-rich brines transitioning into chloride- and sulfate-enriched brines with depth and temperature (Chevrier and Slank, 2024; Stevens and Cockell, 2023). It is important to note that porosity is expected to decrease with depth, which may also influence water availability, with any potential brines increasingly localized to pore spaces and fractures (Michalski et al., 2018). (2) Surface radiation exposure is expected to subside to lower background radionuclide decay around 3–5 m depth. (3) If liquid water is present at depth, chemotrophic microbial communities could utilize the products of water–rock interaction including inorganic electron donors/acceptors and simple abiotic organics.
