"Thanks @ISS_Research for letting me set fires in space for the past month w/ BASS experiment @NASA . #Fire" -- NASA astronaut Tim Kopra Image taken during BASS-II flame test session with reduced O2 (oxygen) partial pressure. BASS-II examines the burning and extinction characteristics of a wide variety of fuel samples in microgravity. The experiment will guide strategies for materials flammability screening for use in spacecraft as well as provide valuable data on solid fuel burning behavior in microgravity. The results will contribute to the combustion computational models used in the design of fire detection and suppression systems in microgravity and on Earth.
