Spacecraft non-sealed instrumentation module outgassing time evaluation

The calculated model and evaluation results of the space craft non-sealed instrumentation module outgassing time in the initial operation period is represented. It s shown that the main influence on the dynamics of the non-sealed instrumentation module outgassing process is exerted upon the dynamics of mass isolation of the included materials. The influence of gas dynamics process outflow from the closed space is less essentially. The typical time of non-sealed instrumentation module outgassing is determined: it's about 2...3 weeks.
