A new analysis of Mars "Special Regions": findings of the second MEPAG Special Regions Science Analysis Group (SR-SAG2).
TLDR
Significant changes in knowledge of the capabilities of terrestrial organisms and the existence of possibly habitable martian environments have led to a new appreciation of where Mars Special Regions may be identified and protected. Expand
Survival of rock-colonizing organisms after 1.5 years in outer space.
TLDR
Evidence is provided of the differential hardiness of cryptoendolithic communities in space, which some-but not all-of those most robust microbial communities from extremely hostile regions on Earth are also partially resistant to the even more hostile environment of outer space. Expand
Survival potential and photosynthetic activity of lichens under Mars-like conditions: a laboratory study.
TLDR
It is presumed that, in any region on Mars where liquid water might be available, even for short periods of time, a eukaryotic symbiotic organism would have the ability to survive, at least over weeks, and to temporarily photosynthesize. Expand
Microbial rock inhabitants survive hypervelocity impacts on Mars-like host planets: first phase of lithopanspermia experimentally tested.
TLDR
A vital launch window for the transport of rock-colonizing microorganisms from a Mars-like planet was inferred, which encompasses shock pressures in the range of 5 to about 40 GPa for the bacterial endospores and the lichens, and a more limited shock pressure range for the cyanobacterium. Expand
Transitory microbial habitat in the hyperarid Atacama Desert
TLDR
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. Expand
Sustainable life support on Mars – the potential roles of cyanobacteria
TLDR
Insights are given into how and why cyanobacteria could play a role in the development of self-sustainable manned outposts on Mars, and a wide range of life-support biological processes based on Martian resources. Expand
Resistance of Antarctic black fungi and cryptoendolithic communities to simulated space and Martian conditions
TLDR
Results clearly suggest a general good resistance of all the samples investigated, and suitable candidates to withstand space flight and long-term permanence in space on the ISS in the framework of the LIchens and Fungi Experiments (LIFE programme, European Space Agency). Expand
Survival of Antarctic Cryptoendolithic Fungi in Simulated Martian Conditions On Board the International Space Station.
TLDR
High stability of the DNA in the cells was demonstrated and data contribute to assessing the stability of resistant microorganisms and biosignatures on the surface of Mars, data that are valuable information for further search-for-life experiments on Mars. Expand
Aerobiology Over Antarctica – A New Initiative for Atmospheric Ecology
TLDR
A consortium of polar aerobiologists is established to bring together researchers with a common interest in the airborne dispersion of microbes and other propagules in the Antarctic, with opportunities for comparative studies in the Arctic. Expand
Metabarcoding of the kombucha microbial community grown in different microenvironments
TLDR
Environmental DNA sequencing revealed a complex and flexible composition of the kombucha microbial culture (KMC) constituting more bacterial and fungal organisms in addition to those found by cultural method, including cultured and uncultivable microorganisms. Expand
