Abstract
The study of microorganism tolerance to extreme influences is an integral part of astrobiology. Despite the large number of works in this field, the limits of maintaining viability and activity remain uncertain, and they are probably much wider than the currently known boundaries, especially taking into account the adaptive capabilities of microorganisms. In the vast majority of astrobiological experiments, a very limited set of organisms and the impact of a small number of factors are studied. It seems natural that research gradually develops from modeling simple systems (pure cultures and single-factor impacts) to more complex ones, closer to hypothetical extraterrestrial ecosystems. Nevertheless, studies of the most complex systems (microbial communities under the complex action of extraterrestrial conditions in laboratory and space experiments) are still extremely few in number. At the same time, some features of multifactor impacts and the response of complex microbial systems to such impacts are often given little attention. This paper attempts to summarize some data on the tolerance of microorganisms to extreme factors of extraterrestrial space, as well as to outline a number of insufficiently studied promising fields of astrobiological research.
期刊介绍:
Solar System Research publishes articles concerning the bodies of the Solar System, i.e., planets and their satellites, asteroids, comets, meteoric substances, and cosmic dust. The articles consider physics, dynamics and composition of these bodies, and techniques of their exploration. The journal addresses the problems of comparative planetology, physics of the planetary atmospheres and interiors, cosmochemistry, as well as planetary plasma environment and heliosphere, specifically those related to solar-planetary interactions. Attention is paid to studies of exoplanets and complex problems of the origin and evolution of planetary systems including the solar system, based on the results of astronomical observations, laboratory studies of meteorites, relevant theoretical approaches and mathematical modeling. Alongside with the original results of experimental and theoretical studies, the journal publishes scientific reviews in the field of planetary exploration, and notes on observational results.
