Mineral alteration in water-saturated liquid CO₂ on early Mars

Aqueous mineral alteration on ancient Mars may have been mediated by reactions with water-saturated liquid CO₂, a hypothesis inspired by carbon sequestration experiments for Earth.

Transient liquid water and water activity at Gale crater on Mars

Liquid water on equatorial Mars is inconsistent with large-scale climatic conditions. Humidity and temperature measurements by the Curiosity rover support the formation of subsurface liquid brines by hydration of perchlorates during the night.

O₂ solubility in Martian near-surface environments and implications for aerobic life

Despite little O₂ in the Martian atmosphere, concentrations of dissolved O₂ in near-surface brines on Mars may be sufficient to support aerobic life, according to solubility calculations.

Methane bursts as a trigger for intermittent lake-forming climates on post-Noachian Mars

Bursts of methane stored in the Martian subsurface may explain intermittent warm climates on ancient Mars, according to numerical simulations. Sedimentary evidence for palaeolakes requires infrequent, yet sustained, lake-forming climates.
