TL;DR: It is shown that even the hyperarid Atacama Desert can provide a habitable environment for microorganisms that allows them to become metabolically active following an episodic increase in moisture and that once it decreases, so does the activity of the microbiota.
Journal ArticleDOI
Deliquescence-induced wetting and RSL-like darkening of a Mars analogue soil containing various perchlorate and chloride salts.
TL;DR: It is shown that the JSC Mars‐1a analogue soil undergoes a darkening process when salts dispersed in the soil deliquesce, but forming continuous liquid films and larger droplets takes much longer than previously assumed, and electrical conductivity measurements correlate well with the deliquescence rates.
Journal ArticleDOI
Methanogenic Archaea Can Produce Methane in Deliquescence-Driven Mars Analog Environments
Deborah Maus,Deborah Maus,Jacob Heinz,Janosch Schirmack,Alessandro Airo,Samuel P. Kounaves,Samuel P. Kounaves,Dirk Wagner,Dirk Schulze-Makuch,Dirk Schulze-Makuch +9 more
TL;DR: It is shown here for the first time that water provided by deliquescence alone is sufficient to rehydrate methanogenic archaea and to reactivate their metabolism under conditions roughly analogous to the near-subsurface Martian environment.
Journal ArticleDOI
Bacterial Growth in Chloride and Perchlorate Brines: Halotolerances and Salt Stress Responses of Planococcus halocryophilus.
Jacob Heinz,Annemiek C. Waajen,Annemiek C. Waajen,Alessandro Airo,Armando Alibrandi,Janosch Schirmack,Dirk Schulze-Makuch +6 more
TL;DR: It is suggested that high-concentrated perchlorate brines on Mars might not be habitable to any present organism on Earth, but extremophilic microorganisms might be able to evolve thriving in such environments.
Journal ArticleDOI
Enhanced Microbial Survivability in Subzero Brines.
Jacob Heinz,Janosch Schirmack,Alessandro Airo,Samuel P. Kounaves,Dirk Schulze-Makuch,Dirk Schulze-Makuch +5 more
TL;DR: Findings have important implications not only for the habitability of cold environments on Earth but also for extraterrestrial environments such as that of Mars, where cold brines might exist in the subsurface and perhaps even appear temporarily at the surface such as at recurring slope lineae.
