Abstract

In view of the increasing number of science experiments being carried out in the Russian Segment of the International Space Station, there is a growing interest in the state of the environment where they are conducted, especially, in the contaminating effects of the external induced contamination are firings of control as dust particles the outgassing system thrusters remaining on atmosphere. Sources of the induced atmosphere of non-metallic materials of the outer coatings, and exhausts the external of various venting systems, as well surfaces after launch from Earth, atmospheric aerosols and space dust. The paper presents results of quartz crystal microbalances molecular depositions measurements that were used for evaluating contamination in the induced atmosphere of the first Soviet orbital stations Salyut-7 and Mir, as well as modules Pirs and Poisk of the Russian Segment of the International Space Station. The results of the experiments show a significant effect of illumination and thermal conditions of the contamination source and the quartz microbalance sensor on the measurement results.
