Cryogenic origin of fractionation between perchlorate and chloride under modern martian climate

The high perchlorate (ClO4−) to chloride (Cl−) ratios observed at the Phoenix landing site, northern polar region of Mars, have been puzzling since detection. However, a lack of understanding of

Chlorate as a Potential Oxidant on Mars: Rates and Products of Dissolved Fe(II) Oxidation

Oxychlorine species are globally widespread across the Martian surface. Despite their ubiquitous presence, the ability of oxychlorine species to serve as oxidants on Mars has largely been unexplored.

Water Vapor Adsorption Provides Daily, Sustainable Water to Soils of the Hyperarid Atacama Desert.

Water is necessary for all life on Earth. Water is so critical that organisms have developed strategies to survive in hyperarid environments. These regions with extremely low water availability are

Physicochemical Parameters Limiting Growth of Debaryomyces hansenii in Solutions of Hygroscopic Compounds and Their Effects on the Habitability of Martian Brines

The availability of liquid water is a prerequisite for all lifeforms on Earth. In hyperarid subzero environments like the Dry Valleys in Antarctica or the near-subsurface of Mars liquid water might

Alkaline lake settings for concentrated prebiotic cyanide and the origin of life

Mimicking the Martian Hydrological Cycle: A Set-Up to Introduce Liquid Water in Vacuum

A system that simulates the environmental conditions of the red planet including its hydrological cycle and created a layer of superficial ice that protects the sample against external radiation and minimizes the loss of humidity due to evaporation to maintain a moss sample in survival conditions in this extreme environment.

Multiple subglacial water bodies below the south pole of Mars unveiled by new MARSIS data

The detection of liquid water by the Mars Advanced Radar for Subsurface and Ionosphere Sounding (MARSIS) at the base of the south polar layered deposits in Ultimi Scopuli has reinvigorated the debate

The archaeal class Halobacteria and astrobiology: Knowledge gaps and research opportunities

Water bodies on Mars and the icy moons of the outer solar system are now recognized as likely being associated with high levels of salt. Therefore, the study of high salinity environments and their



The origins of perchlorate in the Martian soil

Perchlorate (ClO4−) has been detected on Mars, but its production and distribution are unclear. Mechanisms requiring atmospheric chlorine are insufficient for measured concentrations. We conducted
