To investigate the possible interplanetary transfer of life, numerous exposure experiments have been carried out on various microbes in space since the 1960s. In the Tanpopo mission, we have proposed to carry out experiments on capture and space exposure of microbes at the Exposure Facility of the Japanese Experimental Module of the International Space Station (ISS). Microbial candidates for the exposure experiments in space include Deinococcus spp.: Deinococcus radiodurans, D. aerius and D… 
Investigation of the Interplanetary Transfer of Microbes in the Tanpopo Mission at the Exposed Facility of the International Space Station.
TLDR
The goal of this review is to introduce an overview of the Tanpopo mission with particular emphasis on the investigation of the interplanetary transfer of microbes.
Molecular repertoire of Deinococcus radiodurans after 1 year of exposure outside the International Space Station within the Tanpopo mission
TLDR
Results show that the non-sporulating bacterium Deinococcus radiodurans survived long-term low Earth orbit exposure if wavelength below 200 nm are not present, which mirrors the UV spectrum of Mars, where CO 2 effectively provides a shield below 190 nm.
On the Stability of Deinoxanthin Exposed to Mars Conditions during a Long-Term Space Mission and Implications for Biomarker Detection on Other Planets
TLDR
Deinoxanthin proved to be a suitable easily detectable biomarker for the search of Earth-like organic pigment-containing life on other planets, with the only exception of the exposure to simulated solar radiation.
Tolerances of Deinococcus geothermalis Biofilms and Planktonic Cells Exposed to Space and Simulated Martian Conditions in Low Earth Orbit for Almost Two Years.
TLDR
The hypothesis of long-term survival of microorganisms under the harsh environmental conditions in space and on Mars to a higher degree if exposed as biofilm is supported.
Probing the response of Deinococcus radiodurans exposed to simulated space conditions
TLDR
Results point to significant VUV inactivating effects extending beyond the cells' outermost structures, in contrast to a more superficial role that could be expected due to the highly interacting nature of this radiation range.
Proteometabolomic response of Deinococcus radiodurans exposed to UVC and vacuum conditions: Initial studies prior to the Tanpopo space mission
TLDR
The effectiveness of the integrative proteometabolomic approach as a tool in molecular analysis of microbial stress response caused by space-related factors is revealed.
Molecular Mechanisms of Microbial Survivability in Outer Space: A Systems Biology Approach
TLDR
The molecular space-induced alterations of exposed microorganisms in terms of understanding the molecular mechanisms of microbial survival and adaptation to drastic outer space environment are summarized.
DNA Damage and Survival Time Course of Deinococcal Cell Pellets During 3 Years of Exposure to Outer Space
TLDR
The results indicated the importance of the aggregated form of cells for surviving in harsh space environment and support the possibility of microbial cell aggregates (pellets) as an ark for interplanetary transfer of microbes within several years.
Multimicrobial Kombucha Culture Tolerates Mars-Like Conditions Simulated on Low-Earth Orbit.
TLDR
A kombucha multimicrobial culture was exposed to simulated Mars-like conditions in low-Earth orbit (LEO) and after a series of subculturing, the revived communities restored partially their structure and associated activities.
Investigations on the Microbiology of the Stratosphere and Other Habitats in Relation to the Theory of Panspermia
TLDR
It was concluded that the large biological entities isolated from the stratosphere are incoming to Earth from space and continually impact the Earth.

TLDR
The data support the likelihood of interplanetary transfer of microorganisms within meteorites, the so-called lithopanspermia hypothesis.

TLDR
These, and other, experiments reveal the particular barriers to the cross-inoculation of photosynthesis, as well as the possibility of the transfer of oxygenic photosynthesis between one planet and another, as it can initiate large scale biospheric productivity.
Survival of rock-colonizing organisms after 1.5 years in outer space.
TLDR
Evidence is provided of the differential hardiness of cryptoendolithic communities in space, which some-but not all-of those most robust microbial communities from extremely hostile regions on Earth are also partially resistant to the even more hostile environment of outer space.
Biological responses to space: results of the experiment "Exobiological Unit" of ERA on EURECA I.
Microbial survival of space vacuum and extreme ultraviolet irradiation: strain isolation and analysis during a rocket flight.
TLDR
This is the first report on the isolated effect of extreme UV at 30 nm on cell survival, suggesting that in contrast to near UV, membrane proteins rather than DNA were damaged by the radiation.
Survival of microorganisms in a simulated Martian environment
TLDR
Data indicate that organisms exposed to the total solar spectrum did not survive, a time dependent, 1 to 3 log, reduction in numbers occurred in the surface samples that received the solar spectrum minus UV, and subsurface survival varied with depth and type or organism.
Resistance of bacterial endospores to outer space for planetary protection purposes--experiment PROTECT of the EXPOSE-E mission.
TLDR
The data demonstrate the high chance of survival of spores on a Mars mission, if protected against solar irradiation, and will have implications for planetary protection considerations.
