A comprehensive catalogue of the bacteria and fungi found on surfaces inside the International Space Station (ISS) is being presented in a study published in the open-access journal Microbiome. The most prominent bacteria were Staphylococcus (26% of total isolates), Pantoea (23%) and Bacillus (11%). (2014). Bacteria discovered in a 600m-deep hole in Spain have provided tantalising clues about possible alien life that could be hiding on other planets. The researchers found that microbes on the ISS were mostly human-associated. (2013). If panspermia is possible, life must exist much more often than we previously thought. Measuring the resistance of such organisms to space conditions can be applied to develop adequate decontamination procedures.[5]. EPSC2013, 396. [2] NASA has pointed out that normal adults have ten times as many microbial cells as human cells in their bodies. It can resist 3,000 times the amount of radiation that would kill a human and was first isolated in cans of meat subjected to sterilizing radiation. The rover will collect samples, returned to Earth in the next 10 years, that could contain proof of ancient life that once flourished on the red planet. al. The remarkable resilience of bacteria in space has been demonstrated before, when microbes survived after being placed on the exterior of the space station. Interestingly, the vast majority of the 48 strains of bacteria sent were found to grow at a rate very close to that on Earth. LPSC44, 1497. Antibiotic-resistant bacteria are some of the most dangerous kinds on Earth, such as E. Coli and Staphylococcus aureus (staph). The team predicted that colonies of this bacteria more than 1 millimeter in diameter could survive as long as eight years in outer space. The scientific study of microorganisms began with their observation under the microscope in the 1670s by Antonie van … The International Space Station, as photographed by Expedition 56 crew members from a Soyuz spacecraft. Experiments of the adaption of microbes in space have yielded unpredictable results. Anton Shkaplerov, who … Bacteria found inside the ISS include Staphylococcus aureus (commonly found on the skin and in the nasal passage) and Enterobacter (associated with the human gastrointestinal tract). The Japanese Tanpopo mission involved including pellets of dried Deinococcus bacteria within aluminum plates that were placed in exposure panels outside of the space station. in the space-tested lichen species, "Resistance of the Lichen Buellia frigida to Simulated Space Conditions during the Preflight Tests for BIOMEX—Viability Assay and Morphological Stability", "Viability of the lichen Xanthoria elegans and its symbionts after 18 months of space exposure and simulated Mars conditions on the ISS", "Decreased expression of myogenic transcription factors and myosin heavy chains in Caenorhabditis elegans muscles developed during spaceflight", International Caenorhabditis elegans Experiment First Flight-Genomics (ICE-First-Genomics), List of microorganisms tested in outer space, Search for extraterrestrial intelligence (SETI), Habitability of K-type main-sequence star systems, Enceladus Life Signatures and Habitability, Astrobiology Science and Technology for Exploring Planets, European Astrobiology Network Association, National Space Biomedical Research Institute, Adverse health effects from lunar dust exposure, Cardiac rhythm problems during space flight, Central nervous system effects from radiation exposure during spaceflight, Epidemiology data for low-linear energy transfer radiation, Intervertebral disc damage and spaceflight, Psychological and sociological effects of spaceflight, Radiobiology evidence for protons and HZE nuclei, Reduced muscle mass, strength and performance in space, Team composition and cohesion in spaceflight missions, Visual impairment due to intracranial pressure, https://en.wikipedia.org/w/index.php?title=List_of_microorganisms_tested_in_outer_space&oldid=999198959, Short description is different from Wikidata, All Wikipedia articles written in American English, Creative Commons Attribution-ShareAlike License, This page was last edited on 8 January 2021, at 23:56. Bacteria found on the outside of the International Space station could be alien life, according to a cosmonaut who has visited the satellite. (2013). Pasini D. L. S. et al. (2014). They discovered 40,000 different types of … Bacteria from Earth could present a false negative for life on Mars or act as a contaminant on Mars. The ability for bacteria to survive in space while traveling in a hard vacuum under strong radiation and for long periods of time has been a key point for meteorite fossil claims. For the Tanpopo mission, samples of bacteria were prepared in pellets of various thickness and placed in the wells of aluminum plates. Bacteria were some of the first organisms investigated, when in 1960 a Russian satellite carried Escherichia coli, Staphylococcus, and Enterobacter aerogenes into orbit. Russian astronauts found actual living organisms in outer space. The sea-plankton … A type of bacteria that is highly resistant to radiation and other environmental hazards survived outside of the International Space Station for three years, according to a new study. Once in space, these organisms may react in unexpected ways to the environmental conditions that exist in reduced gravity or in the closed environment of a spacecraft. (Nageli) and Haloarcula SP. The microorganisms living on the space station include potentially dangerous bacteria that can cause illness, along with fungi that may be corroding the station itself. Spacewalkers regularly take … Living bacteria have been found on the outside of the International Space Station, a Russian cosmonaut told the state news agency TASS this week. SUMMARY The responses of microorganisms (viruses, bacterial cells, bacterial and fungal spores, and lichens) to selected factors of space (microgravity, galactic cosmic radiation, solar UV radiation, and space vacuum) were determined in space and laboratory simulation experiments. Many kinds of microorganisms have been selected for exposure experiments since, as listed in the table below.

The German Aerospace Center (DLR) led an experiment called BIOMEX, in which organisms such as bacteria, algae, lichens and fungi were exposed to Mars-like conditions aboard the space station. Although the bacteria on the surface of the aggregate, or colony formed by the bacteria, died, the researchers found a protective layer beneath it that ensured the colony survived.

Based on the research team's results, Yamagashi believes that "it is very important to search for life on Mars before human missions to Mars." Back then, space station official Vladimir Solovyov announced, also via TASS, that sea plankton and other microorganisms had been spotted in cosmonauts' spacewalk samples. An experiment has proven that bacteria can survive in the harsh conditions of space for years on end. Next, Yamagashi and his team are interested in conducting more exposure experiments for microbes on NASA's Lunar Gateway. A JPL microbiologist is studying fungi and bacteria as part of International Space Station research. While sometimes the microorganism may weaken, they can also increase in their disease-causing potency. Those that were larger than 0.5 millimeters were able to partially survive, sustaining DNA damage. Pasini D. L. S. et. Study author Akihiko Yamagishi, who is the principal investigator of the Tanpopo space mission, and his team in 2018 used an aircraft and scientific balloons to find Deinococcus bacteria that was actually floating 7.5 miles above Earth's surface. "The results suggest that radioresistant Deinococcus could survive during the travel from Earth to Mars and vice versa, which is several months or years in the shortest orbit," Yamagishi said. It's known as the most radiant-resistant life form in the "Guinness Book of World Records.". Previous studies have suggested that bacteria could survive longer in space if it was shielded by rock, known as lithopanspermia, but this study has shown that bacteria aggregates, or colonies, can survive in space, which is called massapanspermia. Niger Spores", "Resistance of Bacterial Endospores to Outer Space for Planetary Protection Purposes—Experiment PROTECT of the EXPOSE-E Mission", "Growth of Carnobacterium spp. This caused Yamagashi, also a professor of molecular biology at Tokyo University of Pharmacy and Life Sciences, and his team to wonder if this bacteria, which was resistant to ultraviolet (UV) radiation, could actually survive in space and even the journey to other planets through extreme temperature fluctuations and even harsher radiation. Some think that life is very rare and happened only once in the Universe, while others think that life can happen on every suitable planet. In October 2020, a team of researchers announced that microbial diversity below the seafloor is as rich as on Earth’s surface. Project MECCURI focused on how bacteria sampled would survive inside the space station itself. Yamagashi and his team suspect that bacteria could potentially be launched from Earth by the electric field generated in thunderstorms, landing the way that micrometeorites do in the atmosphere of Earth.
