Aerosol Samplers: Today the crew deployed Active Aerosol Samplers (AASs) in Nodes 1 and 3. The battery-powered AASs actively pull in air and collect particles using the principal of thermophoresis. This is accomplished by flowing the sampled air through a large thermal gradient in a narrow channel. During this process, particles are driven to the …
