Space Station conditions are selective but do not alter microbial characteristics relevant to human health

Human space exploration beyond Earth and Moon is a declared goal of NASA, ESA, Roscosmos and other space-faring agencies, with human Mars mission envisioned in the near future. One of the major challenges of the mission is protecting the human crew from illness and infection caused by harmful biological contaminants. To evaluate these challenges in …

Man-made microbial resistances in built environments

Antibiotic resistance has been assessed to rise to dangerously high levels in all parts of the world, and new resistance mechanisms are emerging and spreading globally. At the same time the number of people dying from antibiotic-resistant bacteria is increasing. The World Health Organization considers the spread of antibiotic resistance and appropriate countermeasures as one …

Microbial biodiversity assessment of the European Space Agency’s ExoMars 2016 mission

Determining if life exists or ever existed beyond Earth is one of the most interesting scientific questions. Reports on numerous habitable planets have increased the speculations about potential extra-terrestrial life. However, these theoretically life-supporting planets are far beyond human’s reach – except Mars. In order to explore if there ever was life on Mars, the …

Preparing for the crewed Mars journey: Microbiota dynamics in the confined Mars500 habitat during simulated Mars flight and landing

Human exploration of planet Mars has a long history with number of robotic missions surveying the Martian surface and environment, including  the Viking program (1975), the Mars Exploration Rover Mission (2003), the Phoenix lander (2008), and the Mars Science Laboratory (2012). For the future human space exploration, crewed Mars mission is considered as one of …
