Objective
The two main objectives for BASS are to: 1.) Begin to bridge the gap between the normal gravity NASA-STD-6001 Test#1 method, ground-based microgravity tests, and actual material flammability in microgravity. The relation between these can be investigated by observing flames burning for the longer times available in flight. Practical, realistic (thicker) fuels in typical geometries will be examined, including wake flames which have characteristics of a fire burning behind another object (for example, a fire burning in tight area which may not be easily accessible). 2.) Assess the effectiveness of an inert, gaseous extinguishing agent (similar to that used on ISS) in putting out flames over different materials, geometries, preheating, and flow.
BASS (PSI-26, Microgravity Science Glovebox, International Space Station (ISS)). 121 test runs from NASA PSI (DOI 10.60555/58h4-dy80).
