Flame spreading over wire insulation in microgravity obtained by 10 s drop tower of the Japan Microgravity Center. Uniform low speed air flow is suppled from right to left. Molten PE ball is observed in the flame. Soot particles are continuously emitted at the rear of the flame. 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.
