Bill Sheredy heads NASA's Smoke Aerosol Measurement Experiment (SAME), implemented to design smoke detection devices operable in the micro-gravity environments found in the International Space Station and space shuttle. Fire is deadly and unpredictable on Earth; in an enclosed space vehicle in orbit, its presence takes on even more serious implications. Micro-gravity smoke also has different properties than terrestial smoke. SAME is a part of the larger Fire Prevention, Detection, and Suppression Program at NASA, developing smoke sensors for space and terrestrial applications.
