Results of a study of the influence of outer space conditions on living organisms. For seven years, the period that they decided to allocate for this study, representatives of many living organisms have visited the cosmos. On the outside of the station, a special staff was equipped, in the nests of which samples of terrestrial organisms were located, as well as a multitude of measuring and diagnostic devices. The dose of irradiation was artificially regulated, so the spread could reach 70 percent.
Among the subjects who had been in the open space, spores of bacteria, a series of some plants, lichens and amino acids appeared. Among the organisms that visited the station, lichens demonstrated the best adaptability and survival. These organisms, representing a symbiosis between mushrooms and algae, spent more than a year and a half in orbit and, after returning to Earth, continued their growth.
