DUST

iss055e035971 (4/28/2018) --- Photo documentation of locations of where samples taken by the crew for the Divert Unwanted Space Trash (DUST) operations aboard the International Space Station (ISS). The DUST investigation collects and analyzes particulates in airborne debris from the ISS cabin. Unique aspects of the spacecraft environment, such as lack of gravity and no fresh air, influence the size, quantity, and components of airborne particulate matter, which in turn affects air quality aboard the station. The data also provides baseline information for future spacecraft particle detector design, and the debris can be used for realistic testing of possible particulate monitors for future long-duration missions.
