ISS odor problem solved
Posted: Mon, Feb 25, 2002, 7:41 AM ET (1241 GMT)
A strong odor that filled the US portions of the International Space Station after a Wednesday spacewalk have been removed, NASA reported. The Expedition Four crew reported a strong, musty odor emanating from the Quest airlock after Carl Walz and Daniel Bursch performed a spacewalk using Quest on Wednesday. As a precaution the crew closed the interior hatch of Quest and retreated to the Russian segment of the station. Engineers believe the odor came from a system that bakes metal oxide canisters to remove carbon dioxide from them; mildew may have built up in the system during months of inactivity. The odor was largely removed by Friday and the station crew returned to normal activity by then.
