Material Samples Used in Space Station Smoke Detection Tests

Caption

Four of the five materials used to produce smoke particles in experiments aboard the International Space Station. From left to right: cellulose (cotton fiber), Kapton (polymer for thermal insulation), silicone rubber (for seals and gaskets) and Teflon (for insulating wires). Not pictured: Pyrell (polyurethane foam for packing). Wires conduct electricity which heats the samples and generates smoke.
