A trace of the pyrolysis zone captured by an infrared camera at the near-flammability limit. The experiment reveals an initial linear flame spread which subsequently transitions to a swinging spread, taking a rounded shape. Fundamental Research on International Standard of Fire Safety in Space – Base for Safety of Future Manned Missions (FLARE), a Japan Aerospace Exploration Agency (JAXA) investigation, explores the flammability of materials in microgravity.
