This experiment was aimed at establishing, for the first time, the survival capability of lichens exposed to space conditions. [] Key Method The lichens used were the bipolar species Rhizocarpon geographicum and Xanthoria elegans, which were collected above 2000 m in the mountains of central Spain and as endolithic communities inhabiting granites in the Antarctic Dry Valleys.

Figures and Tables from this paper

UV-C tolerance of symbiotic Trebouxia sp. in the space-tested lichen species Rhizocarpon geographicum and Circinaria gyrosa: role of the hydration state and cortex/screening substances
TLDR
Results indicate that the physiological state of the thallus is the most important factor impairing the tolerance of Trebouxia sp.
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.
Damage escape and repair in dried Chroococcidiopsis spp. from hot and cold deserts exposed to simulated space and martian conditions.
TLDR
Ground-based experiments conducted in the context of Lichens and Fungi Experiments to evaluate the survival of cyanobacteria (Chroococcidiopsis), lichens, and fungi colonized on Antarctic rock found survivors of strain CCMEE 123 were better suited to withstand cellular damage imposed by simulated space and martian conditions.
Die Hard: Lichens
TLDR
The symbiotic association of a heterotrophic fungal and an autotrophic algal (and/or cyanobacterial) partner produces a unique phenotype, the lichen thallus, which can establish long-living individuals under almost all climatic conditions of the authors' planet.
Whole lichen thalli survive exposure to space conditions: results of Lithopanspermia experiment with Aspicilia fruticulosa.
TLDR
The Lithopanspermia space experiment was launched in 2007 with the European Biopan facility for a 10-day spaceflight on board a Russian Foton retrievable satellite, and it was concluded that Aspicilia fruticulosa was capable of repairing all space-induced damage.
Viability of the lichen Xanthoria elegans and its symbionts after 18 months of space exposure and simulated Mars conditions on the ISS
TLDR
This remarkable viability of lichen samples exposed to space conditions and simulated Mars-analogue conditions in the lichen and fungi experiment (LIFE) on the International Space Station is discussed in the context of particular protective mechanisms of lichens such as anhydrobiosis and UV-screening pigments.
Characterisation of Growth and Ultrastructural Effects of the Xanthoria elegans Photobiont After 1.5 Years of Space Exposure on the International Space Station
TLDR
The ultrastructural analysis of the algal cells provided an insight to cellular damages caused by long-term exposure and highlighted that desiccation-induced breakdown of cellular integrity is more pronounced under the more severe space vacuum than under Mars-analogue atmospheric conditions.

Bacillus subtilis spores on artificial meteorites survive hypervelocity atmospheric entry: implications for Lithopanspermia.
TLDR
These experiments constitute the first report of spore survival to hypervelocity atmospheric transit, and indicate that sounding rocket flights can be used to model the high-speed atmospheric entry of bacteria-laden artificial meteorites.
Protection of Bacterial Spores in Space, a Contribution to the Discussion on Panspermia
TLDR
The data suggest that in a scenario of interplanetary transfer of life, small rock ejecta of a few cm in diameter could be sufficiently large to protect bacterial spores against the intense insolation; however, micron-sized grains, as originally requested by Panspermia, may not provide sufficient protection for spores to survive.
Photoinhibition in lichens depends on cortical characteristics and hydration

UV‐induction of sun‐screening pigments in lichens
TLDR
Melanins and parietin were only synthesized in thalli being hydrated during UV-exposures, suggesting that induction required active metabolism.

TLDR
The present "renaissance" of chlorophyll fluorescence may be the product of a fruitful dynamic interaction between three different research disciplines, i.e., basic and applied research linked to new developments in instrumentation and methodology.
