Smoke
Aerosol Measurement Experiment
(SAME)
Home Page
and Introduction
SAME is the successor to the Comparative Soot Diagnostics (CSD) experiment that flew aboard STS-75 in 1996. The CSD experiment showed that smoke produced in low gravity is different from smoke produced in normal gravity (microgravity smoke particles are larger). Since all smoke detectors are designed to detect smoke particles in particular size ranges, they respond differently in a microgravity environment than on Earth, making it important to study microgravity properties of smoke.
The Purpose of SAME
 |
| The Smoke Aerosal Measurement Experiment (SAME) in the Microgravity Science Glovebox (MSG). The holes allow the astronauts to insert their hands into the MSG and manipulate the experiment. |
SAME will evaluate the smoke detectors used on the space shuttles and the International Space Station (ISS) and identify ways in which they can be improved. Importantly, it will test how well the smoke detectors perform when exposed to the smoke particles produced by material commonly found on a spacecraft, such as Teflon®, silicon, cellulose, and the simple, reference material dibutylphthalate (which is often used in the flexible PVC industry to make flooring; wire and cables; pipe; and tubes). The experiment will be conducted in the controlled environment of the Microgravity Science Glovebox.
The knowledge gained from SAME will be used to improve the effectiveness of smoke detectors aboard spacecraft.
