The hypothesis called “panspermia” proposes an interplanetary transfer of life. Experiments have exposed extremophilic organisms to outer space to test microbe survivability and the panspermia hypothesis. Microbes inside shielding material with sufficient thickness to protect them from UV-irradiation can survive in space. This process has been called “lithopanspermia,” meaning rocky panspermia. We previously proposed sub-millimeter cell pellets (aggregates) could survive in the harsh space…

Non-random genetic alterations in the cyanobacterium Nostoc sp. exposed to space conditions

The variant profile showed that biofilm and photosystem associated loci were the most altered, with an increased variant rate of synonymous base pair substitutions, and the cause(s) of these non-random alterations and their implications to the evolutionary potential of single bacterial cells under long-term cosmic exposure warrants further investigation.

To the best of the knowledge, this is the first pure strain of Nostoc sp.

Mutation Analysis of the rpoB Gene in the Radiation-Resistant Bacterium Deinococcus radiodurans R1 Exposed to Space during the Tanpopo Experiment at the International Space Station.

The experiment suggests that the dried cells of the microorganism D. radiodurans can travel without space-specific deterioration that may induce excess mutations relative to travel at Earth's surface.

Proteomic Response of Deinococcus radiodurans to Short-Term Real Microgravity during Parabolic Flight Reveals Altered Abundance of Proteins Involved in Stress Response and Cell Envelope Functions

The present study aims to elucidate the short-term proteomic response of this species to real microgravity during parabolic flight and suggests molecular rearrangements in the cell envelope of D. radiodurans could be linked with increased endogenous ROS production that contributes to the stress response.

CRISPRi in Deinococcus radiodurans

The programmable CRISPRi tool developed in this study will facilitate study of essential genes, hypothetical genes, cis-elements involved in radiation response as well as enable metabolic engineering in this organism and is amenable for implementing high-throughput approaches for such studies.

Conjugation-based genome engineering in Deinococcus radiodurans

The development of a simple and robust conjugation-based transformation system from E. coli to D. radiodurans allowing for the introduction of stable, replicating plasmids expressing antibiotic resistance markers and a protocol for creating sequential gene deletions in D. Radioduran by targeting re-striction-modification system genes.

Database of space life investigations and bioinformatics of microbiology in extreme environments

The Space Life Investigation Database (SpaceLID), which collected SLIs from published academic papers, provides detailed menu search facilities and categorized contents about the studied phenomena, materials, experimental procedures, analysis methods, and research outcomes of 448 SLIs, including 232 SLIs not covered by the established databases.

Survival of rock-colonizing organisms after 1.5 years in outer space.

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.

Protection of Bacterial Spores in Space, a Contribution to the Discussion on Panspermia

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.

Onboard of several spacecrafts, spores of Bacillus subtilis were exposed to selected parameters of space, such as space vacuum, different spectral ranges of solar UV-radiation and cosmic rays, applied separately or in combination, and their survival and genetic changes after retrieval are studied.

The Possible Interplanetary Transfer of Microbes: Assessing the Viability of Deinococcus spp. Under the ISS Environmental Conditions for Performing Exposure Experiments of Microbes in the Tanpopo Mission

It is concluded that aggregated deinococcal cells will survive the yearlong exposure experiments of the International Space Station, and it is proposed that microbial cells can aggregate as an ark for the interplanetary transfer of microbes, and is named ‘massapanspermia’.
