The impact of climatic factors in the conditions of the Far North and the Arctic, as shown by the work of foreign and domestic researchers, reduces the strength properties of polymer composite materials (PCM). The destruction processes occurring in the PCM under the influence of solar radiation and alternating ambient temperatures can also affect the thermophysical properties, one of the characteristics of which is thermal conductivity. The purpose of the work is to study the thermal conductivity of PCM samples under the influence of solar radiation and extreme climatic temperatures of the surrounding air.

The development of regression models for estimating monthly global solar radiation in the eastern regions of the Far North and the Arctic zone of the Russian Federation was carried out. The deviation of the model estimates of the annual global solar radiation does not exceed 10% for the Arctic zone and 8% for the regions of the Far North. The accuracy of regression model estimates was compared with the data from the ERA5, SYN1Deg databases in Oymyakon and Yakutsk. A regression model based on the support vector machine has been developed to estimate the daily global solar radiation. The results of model validation based on meteorological data of Oymyakon and Yakutsk are presented.

The article is devoted to the formation of functional literacy on the example of texts on the topical topic of space exploration. The authors touch upon the problems of space security and space debris. Much attention is paid to the popular topic of space tourism: the issues of flight financing, requirements for the health of space tourists are considered. The materials of the article can be used in extracurricular activities during events dedicated to the Cosmonautics Day.
