Abstract

The subject of the article is the planning and comprehensive preparation of an experiment for monitoring the condition of a satellite’s structure under vacuum conditions modelled using a space environment simulator. Simulating the space environment is essential for verifying the performance of materials, structural components and equipment prior to their actual launch. Such testing makes it possible to confirm the correctness of material selection, the accuracy of engineering calculations and the validity of technical decisions made during the design phase. The behaviour of materials under vacuum, extreme temperatures, sharp thermal fluctuations, and exposure to cosmic radiation may differ significantly from their performance under standard operating conditions on Earth.
