Description
This is the accepted manuscript of the paper: de Vera J.P., Alawi M., Backhaus T., Baque M., Billi D., …… Zucconi L. (2019). Limits of Life and the Habitability of Mars: The ESA Space Experiment BIOMEX on the ISS. Astrobiology 19(2), 145-157. DOI: 10.1089/ast.2018.1897
Abstract:
BIOMEX (BIOlogy and Mars EXperiment) is an ESA/Roscosmos space exposure experiment housed within the
exposure facility EXPOSE-R2 outside the Zvezda module on the International Space Station (ISS). The design of
the multiuser facility supports—among others—the BIOMEX investigations into the stability and level of degradation
of space-exposed biosignatures such as pigments, secondary metabolites, and cell surfaces in contact with
a terrestrial and Mars analog mineral environment. In parallel, analysis on the viability of the investigated organisms
has provided relevant data for evaluation of the habitability of Mars, for the limits of life, and for the
likelihood of an interplanetary transfer of life (theory of lithopanspermia). In this project, lichens, archaea, bacteria,
cyanobacteria, snow/permafrost algae, meristematic black fungi, and bryophytes from alpine and polar habitats
were embedded, grown, and cultured on a mixture of martian and lunar regolith analogs or other terrestrial
minerals. The organisms and regolith analogs and terrestrial mineral mixtures were then exposed to space and to
simulated Mars-like conditions by way of the EXPOSE-R2 facility. In this special issue, we present the first set of
data obtained in reference to our investigation into the habitability of Mars and limits of life. This project was
initiated and implemented by the BIOMEXgroup, an international and interdisciplinary consortiumof 30 institutes
in 12 countries on 3 continents. Preflight tests for sample selection, results from ground-based simulation experiments,
and the space experiments themselves are presented and include a complete overview of the scientific
processes required for this space experiment and postflight analysis. The presented BIOMEX concept could be
scaled up to future exposure experiments on the Moon and will serve as a pretest in low Earth orbit.
