Outgassing Rates
Outgassing rates refer to the amount of gas that is released by a material when it is exposed to a vacuum. In the context of space and astronautical engineering, outgassing rates are an important consideration for spacecraft and their components. This is because the gas released by materials can contaminate sensitive instruments and optics, leading to reduced performance or even mission failure. Outgassing rates are typically measured using a mass spectrometer, and materials with low outgassing rates are preferred for use in space applications. Materials that are known to have low outgassing rates include certain types of plastics, metals, and ceramics.
