Responses of the Black Fungus Cryomyces antarcticus to Simulated Mars and Space Conditions on Rock Analogues
The BIOMEX (BIOlogy and Mars Experiment) is part of the European Space Agency (ESA) space Mission EXPOSE-R2 in Low-Earth Orbit, devoted to exposing microorganisms for 1.5 years to space and simulated Mars conditions on the International Space Station. In preparing this mission, dried colonies of the...
