The сoncept that MVs may contribute to astronauts’ health probably to the same extent as their parental microbial cells do and be a temporary substitute for living microbial cells until we know more about the behavior of microbes in the space environment. The advantage of MVs is that they are not alive and cannot be changed under unfavorable conditions as microbial organisms may be. As the model, we selected MVs of a robust to environmental factors kombucha multimicrobial culture (KMC), known for its health-promoting characteristics for humans. We exposed KMC on the International Space Station in a hybrid space/Mars-like environment for an initial proof-of-concept stage. In the exposure study, KMC has survived a long-term period in harsh conditions, and the MVs generated by post-flight kombucha community members did not acquire toxicity, despite the changed membrane composition in the environment imitated conditions on the Mars surface. This observation, together with our KMC metagenomic and comparative genomic analyses of the dominant KMC bacterium Komagataeibacter oboediens, showed that the ground reference sample and spaceexposed ones were similar in topology and maintained their stability. In the next stage, we assessed the fitness, safety, and biodistribution of MVs of post-flight K. oboediens and showed that they were altered, but the modifications in membrane structure did not result in toxicity acquisition. Our proof-of-concept strategy is discussed in this review in line with the literature.","PeriodicalId":42936,"journal":{"name":"Space Science and Technology-Kosmicna Nauka i Tehnologia","volume":null,"pages":null},"PeriodicalIF":0.4,"publicationDate":"2022-12-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49295248","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Podolinskyi. And the characteristics of S. A. Podolinskyi as a “forgotten scientific innovator”, which was given to him by V. I. Vernadskyi at the beginning of the 20th century, remains largely fair even today. The article was prepared for the 150th anniversary of the “energy concept” of S. A.

Podolinskyi in the context of the impact of work on the distribution of solar energy on the Earth’s surface. Ideas of S. A. Podolinskyi, presented in his work “Man’s work and its attitude to the distribution of energy” testify not only to the priority of domestic science on many issues of natural science, the relevance of which is realized only in our time, but also retain methodological value in the world context. In the work of S. A. Podolinskyi’s reader will find an example of the formulation and approach to solving an interesting and necessary problem in the scientific field, which are characteristic of outstanding and original scientists. The most important is the opening of S. A. Podolinskyi that the development of living organisms on the Earth’s surface occurs under the influence of solar energy. That is why the name S. A. Podolynskyi is deservedly mentioned among the predecessors of V. I. Vernadskyi, who studied the energetics of living matter and the formation of the doctrine of the biosphere and noosphere. The importance of the work of S. A. Podolinskyi is considered and its further prospects in the development of scientific research on the use of energy.","PeriodicalId":42936,"journal":{"name":"Space Science and Technology-Kosmicna Nauka i Tehnologia","volume":null,"pages":null},"PeriodicalIF":0.4,"publicationDate":"2022-12-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67117697","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

According to satellite observations, large-amplitude acoustic-gravity waves are systematically observed in the regions of formation of powerful wind systems. At the same time, the azimuths of AGW propagation are spatially consistent with the directions of wind circulation. Waves propagate mainly against the wind, and their amplitude is approximately proportional to the wind speed. In order to explain the experimental data, the paper theoretically investigated the changes in the amplitudes of AGW in a horizontally inhomogeneous wind flow. The dispersion equation of the AGW in the reference frame of the medium, which moves with a non-uniform speed, was obtained. When obtaining it, inertial forces were taken into account, as well as the change in the background density of the atmosphere in an inhomogeneous flow. It is shown that under the slow change in wind speed, the real part of this equation coincides with the dispersion equation of AGW for a stationary medium. An expression for the change in the amplitude of waves in a moving medium was obtained, according to which, in an oncoming inhomogeneous wind, the amplitude of the wave increases approximately according to a linear law, which is consistent with the data of satellite observations.","PeriodicalId":42936,"journal":{"name":"Space Science and Technology-Kosmicna Nauka i Tehnologia","volume":null,"pages":null},"PeriodicalIF":0.4,"publicationDate":"2022-12-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47702865","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Development of neurotoxicity under conditions of altered gravity may result from excess extracellular glutamate caused by the reverse functioning of glutamate transporters. Under conditions of moderate and deep hypothermia, a gradual decrease in the transporter-mediated release of L-[14C]glutamate from nerve terminals was demonstrated, which is stimulated by plasma membrane depolarization with KCl and dissipation of the proton gradient of synaptic vesicles by the protonophore FCCP. This fact indicates a neuroprotective effect, which increases when hypothermia changes from moderate to deep. The possible risks of using hypothermia in space medicine have been determined. Hypothermia is not able to reduce the extracellular level of L-[14C]glutamate and [3H]GABA, which increases under the conditions of exposure to carbon-containing planetary dust. Hypothermia can lead to a further decrease in the rate of accumulation of neurotransmitters in the presence of carbon-containing planetary dust and to contribute to the development of neurotoxicity, which is a possible risk of using hypothermia in space medicine. In this context, it is important to choose the optimal individual temperature regime for each astronaut.","PeriodicalId":42936,"journal":{"name":"Space Science and Technology-Kosmicna Nauka i Tehnologia","volume":null,"pages":null},"PeriodicalIF":0.4,"publicationDate":"2022-12-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67117068","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is shown that the seismic-ionospheric effect is global, which is superimposed by local effects over the epicenters of individual earthquakes (EQ). Temporal TEC variations near the time of strong EQs at a great distance from their epicenters (global effect) consist of two maxima: the precursor and the «aftershock» maximum. In TEC variations over the EQ epicenter (local effect), only a precursor is usually registered, the amplitude of which at night (on average, ~ 8 %) is about twice as high as during the day. Always (locally and globally) after a positive surge in TEC, its reduced values are observed for several days. The maximum amplitude zone of the seismic-ionospheric effect belongs to the middle latitudes, especially 35...40° N, and within this zone at longitudes near 30° W (Mid-Atlantic ridge) and 140...150° E (Japanese islands and adjacent waters of the Pacific Ocean). Latitudinal amplitude maxima of the seismic-ionospheric effect are in good agreement with the latitudinal maxima of the EQ number in both geographic and geomagnetic coordinate systems. Changes in the EQ number and, consequently, the effect in the ionosphere on geomagnetic coordinates are more ordered, which indicates a significant impact on the seismicity of the same processes at the boundary of the liquid core and lower mantle, which form the Earth’s magnetic field. In addition to seismic belts and zones of mid-ocean ridges, an increase in TEC has been recorded along the so-called lineaments, marking the weakened zones of the Earth’s crust with increased flows of deep gases. The correspondence between the spatial features of seismicity and the seismic-ionospheric effect testifies in favor of the «radon» mechanism of lithosphere-ionosphere coupling and indirectly confirms the role of deep gases in the formation of seismicity planetary features.","PeriodicalId":42936,"journal":{"name":"Space Science and Technology-Kosmicna Nauka i Tehnologia","volume":null,"pages":null},"PeriodicalIF":0.4,"publicationDate":"2022-12-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47770733","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

During the passive flight of the space stage (after its main engine shutdown), the liquid propellant in the tanks continues to move by inertia in microgravity away from the propellant management device as much as possible. In this case, the pressurization gas is displaced to the propellant management device, which creates the potential danger of gas entering the engine inlet in quantities unacceptable for the reliable engine restart. In this regard, determining the parameters of fluid movement in propellant tanks in microgravity conditions is an urgent problem that needs to be solved in the design period of liquid propulsion systems. We have developed an approach to the theoretical computation of the parameters of the motion of the ‘gas — fluid’ system in the propellant tanks of modern space stages in microgravity conditions. The approach is based on the use of the finite element method, the Volume of Fluid method and modern computer tools for finite-element analysis (Computer Aided Engineering — CAE systems). For the passive leg of the launch vehicle space flight, we performed mathematical modeling of the spatial movement of liquid propellant and forming free gas inclusions and determined the parameters of movement and shape of the free surface of the liquid in the tank as well as the location of gas inclusions. The numerical simulation of the fluid movement in an experimental sample of a spherical shape tank was performed with regard to the movement conditions in the SE Yuzhnoye Design Bureau ‘Drop tower’ for studying space object s in microgravity. The motion parameters of the ‘gas — fluid’ interface obtained as a result of mathematical modeling are in satisfactory agreement with the experimental data obtained. The use of the developed approach will significantly reduce the amount of experimental testing of the designed space stages.","PeriodicalId":42936,"journal":{"name":"Space Science and Technology-Kosmicna Nauka i Tehnologia","volume":null,"pages":null},"PeriodicalIF":0.4,"publicationDate":"2022-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67117453","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Data were obtained from ground-based photometric observations in filters B, V, and R. Among studied satellites, there are „Astra 2E” (bus Eurostar-3000), „Azerspace 2/Intelsat 38” (bus SSL-1300), „Sicral 2” (bus Spacebus-4000B2), „Сosmos 2520/ Blagovest 11L” (bus Ekspress-2000). It was revealed that the nature of the change in the surface reflectivity for the different satellites differs. Space materials on the surface of geostationary satellites manufactured in the second decade of the 21st century demonstrate that their surface is more resistant to the aggressive space environment than that of the satellites manufactured in the late 20th century.
