Methane and carbon monoxide are gaseous contaminants commonly found in a crewed spacecraft’s cabin environment that are of interest to trace contaminant control equipment design. Generation sources include crew metabolism and equipment offgassing. Sources and generation rates of methane and carbon monoxide aboard the International Space Station (ISS) are examined. Cabin atmosphere concentration dynamics covering 19 years of ISS crewed operations are presented and correlation with octafluoropropane (Freon 218) concentration levels is analyzed.
