Composite materials are planned to be widely used in prospective large-sized space structures. The functional characteristics of such structures depend on the thermal regime. The report reveals the features of modeling the thermal regime of a large-sized space structure on the example of a space debris trap. It is intended that the transformable power elements of the trap have to be made of carbon composite, and the panels, holding space debris – from the hybrid composite. Estimations of the temperature levels of the structural elements corresponding to the flight conditions along the geostationary orbit are given. The hazard level of permissible temperatures exceedence and their effect on the resistance of a hybrid composite material (CM) panels to small space debris particles impact is analyzed.

Material science problems of building space antennas with a transformable reflector 100 m in diameter

The article discusses atomic emission spectroscopy as an elemental analysis method based on the analysis of optical line emission spectra of atoms in the gas phase. During the transition of one or more electrons from a low energy level (ground state) to a higher energy level (excited state), excess energy is released in the form of radiation, in this state the electron stays for a very short time (8-10 seconds), because it is not stable. Because an atom has only a discrete set of energy levels, then the emission corresponds to a specific value of energy (or frequency and wavelength) in the form of radiation.
