“…Solar panels are known to suffer significant damage from micrometeorites and free-floating debris, for which protection systems are applied, and repair and replacement of individual panels are provided (Christiansen et al, 2006). Optimum orientation (Yermoldina et al, 2019) is provided with movable joints. The solar panels are also duplicated by a backup source, a 2 Megawatt generator, which will be powered by the methane-powered internal combustion engine.…”

The vast majority of contemporary conflicts between states are of a hybrid nature. This is due to the complexity of processes taking place in the international arena. One aspect of the hybrid nature of conflicts is the issue of information warfare. The Ukrainian-Russian conflict, which has lasted since 2014, contains all the attributes of a hybrid conflict. Understanding and a thorough analysis of the relations between these countries require the atomization of the scope of the concept of hybrid war and its individual fragments. The authors of this article focus on the issue of information warfare carried out by the Russian Federation in relation to Ukraine and the issue of media literacy in the educational sphere as a tool aimed at counteracting this type of destructive policy by the Kremlin.

This paper investigates the on-orbit maintenance task planning of large-scale space solar power station. The research is of great significance for the normal operation of large-scale space equipment. Space robots are very maneuverable, which makes space maintenance possible. A new task planning algorithm is proposed for the on-orbit maintenance of space robots. Firstly, based on the discretization method, the modified clustering method is used to cluster the maintenance area of large-scale space solar power stations. Secondly, the hierarchical structure principle is used to assign tasks to the space robot, the inner layer plans the shortest path within the cluster set, and the outer layer plans the optimal path between the cluster sets. Finally, based on the optimal path of the outer layer of the maintenance task, a hybrid optimization algorithm based on tabu algorithm and modified ant colony algorithm is proposed. The algorithm can meet the space machine task allocation requirements and analyze the maintenance path under certain energy conditions. The simulation results show that the proposed algorithm can effectively solve the optimal problem of space robot mission planning under resource constraints. INDEX TERMS Space robot, task clustering, hybrid optimization algorithm, task planning.

“…The vision of harnessing solar power from space for terrestrial markets inspires continuous efforts in Space Solar Power Station (SSPS) projects [19][20][21][22]. Among these projects, the SSPS-OMEGA (Orb-Shape Membrane Energy Gathering Array) concept [23] is our focus, and in this project, a high-gain and large-aperture (100 m) antenna is one of its core components.…”

Front-fed parabolic reflectors are among the most commonly used antennas in the industry. While in spaceborne applications, membrane reflectors are very promising due to their lightweight and foldable features. However, considering the large size, small thickness and low stiffness, solar radiation and microwave radiation will have considerable influences on the antennas' shape accuracy as well as the radiation characteristics. In this article, a theoretical approach is presented to solve the multi-physical effects of the parabolic antenna. The deformation of the reflector is derived by the shallow shell theory, taking into account the solar pressure, the microwave pressure and the thermal effects due to solar and microwave heating. The far-field electromagnetic radiation pattern is then obtained by considering the deformation of the reflector. On the other hand, a numerical approach combining the finite element method, the multi-level fast multipole method, and the large element physical optics is also presented. Numerical examples suggest good agreement between the theoretical and numerical results. The methods have been applied into the analysis of design models in the Space Solar Power Station project. Also, these approaches can be directly extended into other space membrane reflector antennas.This is an open access article under the terms of the Creative Commons Attribution-NonCommercial-NoDerivs License, which permits use and distribution in any medium, provided the original work is properly cited, the use is non-commercial and no modifications or adaptations are made.
