Abstract
On occasion, seemingly normal operations can have significant effects upon the closed environment of the International Space Station (ISS). An example of such a case occurred on February 20, 2002 when a nominal Metal Oxide (MetOx) canister regeneration operation onboard the ISS resulted in an unexpected, foul odor that affected the crew and station operations. A case study summarizing the root cause for the event and steps taken to ensure that future MetOx regeneration operations proceed safely is presented. Included in the summary are engineering analyses and environmental monitoring results supporting the root cause assessment as well as testing conducted and flight operations changes implemented to ensure safe operations.
