资源简介：
Aerosols are small particles suspended in the air, and in Earth’s atmosphere, aerosols include soot, dust, pollen and a wide range of other natural and human-made materials. Smoke does not rise and dust does not settle in microgravity the way they do on Earth, causing aerosols to behave differently and pose hazards for crew members breathing the air. The Aerosol Sampling Experiment (ASE) collects airborne particles in the International Space Station’s (ISS) cabin air, and returns them to Earth for scientists to study.
The objectives of ASE were:
1- Characterize airborne particulate matter aboard the ISS to assess air quality for crew health and hardware longevity.
2- Identify particle sources (e.g., human skin, equipment wear, biological contaminants) in the spacecraft environment.
3- Improve understanding of particle transport and accumulation in microgravity conditions.
4- Support design of future spacecraft air filtration systems, ensuring they are appropriately targeted for actual airborne particle profiles.
