MOSCOW, 26 APR – RIA Novosti. Scientists of the space research Institute (IKI) Russian Academy of Sciences the experiments proved that microorganisms are able to survive in the atmosphere of Venus, on the surface of Mars and the ice moons of Jupiter of Europe. This is stated in the annual report for ICA 2019, published on the website of the Institute.
“In the atmosphere of Venus where the upper layers of the planet’s atmosphere is exposed to cosmic rays and temperature jumps, may contain microorganisms associated with the particles” – suggested the scientists ICA.
To test this hypothesis in the laboratory was investigated the effect of radiation on micromycetes (microscopic fungi – ed.) of dry soil at low temperature and pressure. In the end, it was found that the effect of high doses of ionizing radiation leads to the destruction of soil fungi. The most resistant species survive.
in addition, scientists ICA researched survival taken in the Arctic microorganisms to simulated conditions of the Martian surface is irradiated by a radiation, a temperature of minus 50 degrees Celsius.
“it is Shown that this impact has not led to significant damage of bacterial complex”, – stated in the document.
in Addition, scientists investigated the bacteria of the soil of the Mojave desert that are regarded as terrestrial analogues of a hypothetical microbial communities of Mars. “The high number and diversity of microorganisms and the high resistance of bacterial cultures to a wide range of stress factors, such as cultivation temperature, pH, presence of salts and strong oxidizing agents”, the report says.
Also, the ICA assessed the possibility of maintaining a hypothetical microorganisms in the ice of Jupiter’s moon Europe in the event of a release from the under-ice ocean. The experiment on irradiation imbedded in the ice bacteria at a temperature of minus 130 degrees Celsius and the required pressure. The study scientists have discovered viable bacteria.
“given the intensity and speed of updates surface assumes the preservation of living cells in the ice at depths of 10-100 cm for 1000 to 10000 years after the release of water from subglacial ocean” – said in a report on the results of research.
