Problems of robotic systems testing for moving on space objects

The article discusses the issues of providing full-scale testing of machines and spacecraft. The authors consider the surface of a cosmic body and propose the creation of an analogue of the regolith of the Moon and Mars. It is noted that it is necessary to observe not only the physicochemical and granulometric composition of the analogue, but also its electromagnetic charge, which will allow testing robotic systems more fully. Conclusions and description of the process of regolith creation and its properties are given. Key words Robotic system, space, regolith, electromagnetic properties, physical modeling.

Aperiodic and wave disturbances in the ionosphere: the results of vertical sounding»

The monograph presents the study results of aperiodic and quasi-periodic wave perturbations in the ionosphere during unique phenomena in geospace: partial solar eclipses, the fall of the Chelyabinsk cosmic body and during the operation of a powerful radio source – the heating stand «Sura». Experimental data obtained by the method of remote sensing are analyzed. Designed for scientists in the field of ionosphere physics, radio physics, radar, as well as for lecturers, graduate and Ph.D. students.

Swarm of fragments from the Tunguska event

ABSTRACT The Tunguska event took place on 1908 June 30. It was accompanied by an abnormal effect on the Earth's atmosphere, manifesting itself through ‘white nights’. These nights were associated with a dispersion of cosmic matter and the formation of a field of noctilucent clouds with a uniquely large size of over 10 million km2. However, overall, the cosmic matter was scattered over a territory of around 18 million km2. The most likely cause of the Tunguska event was the flux of fragments from the broken-up cometary object. The destruction of the cosmic body over Siberia, according to local inhabitants, was marked by numerous sound phenomena. After analysing eyewitness accounts, we can conclude that there were at least two major objects at the Tunguska event. The largest object exploded over the Taiga and caused damage to the forest. In addition, there were several dozen fragments of around 10 m in size, as well as many fragments of a smaller size.

Being a Living-System

If astrobiology provides a credible way of thinking about what it means to ‘live’ on and with the wider habitats of any cosmic body, then existing sets of symbols must be reinterpreted in order to develop a meaningful way of being-in-the-world and belonging-together-with-the-world in light of the astrobiological concern for intra-action that counters tendencies to human exceptionalism. This chapter makes overlapping arguments that deal with the nature of such symbols. It first examines the relationship between Christian doctrine and symbols to make a case for why doctrines might be reclaimed as symbols in constructive theological reflection if they are not used primarily for apologetic purposes but to facilitate the meaningful re-orientation of our existence in the world. It then considers the Imago Dei as such a doctrinal symbol. Resisting the tendency to turn the doctrine into a freestanding account of biblical anthropology, the chapter draws out resonances between astrobiology’s account of intra-action and the harmonious ordering of creation in cosmogonies that can ground subsequent interpretation of the symbol.
