Quantitative evaluation of bioaerosols in different particle size fractions collected on the International Space Station (ISS)

Published by Open Science Data Repository | National Aeronautics and Space Administration | Metadata Last Checked: October 28, 2025 | Last Modified: 2025-08-21
Exposure to bioaerosols can negatively impact human health. On the International Space Station (ISS) this exposure differs to that on Earth due to lack of gravitational settling and differing microbial sources. It is unknown how microbes are influenced by different particle size fractions in microgravity. The goal of this study is to identify the microbial communities on different particle size fractions taken from the ISS.
