Abstract
During ground-based thermal vacuum tests of spacecraft, it is necessary to control and monitor the change in dust content in closed and semiclosed hollows of the spacecraft, near the optical surfaces of scientific and service hardware, mirrors, solar arrays, multilayer insulation, as well as in the volume of the thermal-vacuum chamber itself during its evacuation etc. It is known that the scientific reliability and significance of the results from instruments in space to ground-based research centers are greatly affected by dusty optics. The article provides a description of a new method for automated dust control of the external atmosphere of a spacecraft and its modules during thermal vacuum tests. A patent has been issued for this method; the patent holder is the Russian Federation, on behalf of which the State Space Corporation Roscosmos acts (RU). In addition to the rocket and space and aviation industries, this method can be used in electronic and microelectronic technology, nuclear technology, medicine, the food industry, etc.
