Tardigrades survive exposure to space in low Earth orbit
TLDR
It is shown that tardigrades are also able to survive space vacuum without loss in survival, and that some specimens even recovered after combined exposure to space vacuum and solar radiation. Expand
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.

A biosensor for environmental genotoxin screening based on an SOS lux assay in recombinant Escherichia coli cells
TLDR
Results indicate that the SOS lux test is potentially useful for the in situ and continuous detection of genotoxins. Expand
EXPOSE-R2: The Astrobiological ESA Mission on Board of the International Space Station
TLDR
The EXPOSE-R2 facility, the experimental samples, mission parameters, environmental parameters, and the overall mission and MGR sequences are described, building the background for the research papers of the individual experiments, their analysis and results. Expand
Irradiation of plasmid and phage DNA in water-alcohol mixtures: strand breaks and lethal damage as a function of scavenger concentration.
TLDR
The yields of strand break formation and biological inactivation as a function of OH scavenger concentration for 60Co gamma-irradiated pBR322 plasmid and M13mp9 RF phage DNA are measured and the dependence on scavenging capacity of the ssb yield could be quantitatively accounted for. Expand
EXPOSE-E: an ESA astrobiology mission 1.5 years in space.
TLDR
Exposure-E provided accommodation in three exposure trays for a variety of astrobiological test samples that were exposed to selected space conditions: either to space vacuum, solar electromagnetic radiation at >110 nm and cosmic radiation (trays 1 and 3) or to simulated martian surface conditions (tray 2).

UV-radiation-induced formation of DNA bipyrimidine photoproducts in Bacillus subtilis endospores and their repair during germination.
TLDR
SP lyase, with respect to nucleotide excision repair, has a remarkable impact on the removal of SP upon spore germination. Expand
EXPOSE, an Astrobiological Exposure Facility on the International Space Station - from Proposal to Flight
TLDR
Two sets of astrobiological experiments in two EXPOSE facilities have been successfully launched to the International Space Station for external exposure for up to 1.5 years. Expand
Exposure of Arctic Field Scientists to Ultraviolet Radiation Evaluated Using Personal Dosimeters
TLDR
Time‐integrated exposures showed that the type of outdoor field activities in the treeless expanse of the polar desert had little effect on the exposure received, although absolute exposure changed in accordance with the time of day, the exposure ratio did not vary much over the day. Expand
Temporal dynamics of the gut microbiota in people sharing a confined environment, a 520-day ground-based space simulation, MARS500
TLDR
Sharing life in a confined habitat does not affect the resilience of the individual gut microbial ecosystem, even in the long term, but the temporal dynamics of certain microbiota components should be monitored when programming future mission simulations and real space flights, to prevent breakdowns in the metabolic and immunological homeostasis of the crewmembers.
