Researchers from NASA's Glenn Research Center and Johnson Space Center and Case Western Reserve University have revealed plans to test the flammability of materials on the Moon's surface. The scientists expect flame to act differently than it does on Earth, where gravity causes hot gases to rise, leading to a phenomenon called "blowoff". This could result in materials that might not be flammable on Earth could burn for a long time on the moon. The researchers also found that the International Space Station's ventilation systems could not prevent fires that would damage material. The best solution was to test flames on the ISS, where researchers lit 1,500 small ones to study how combustion works. However, dropping testing was deemed inadequate due to the complexities of fire in space. The next step is to observe how flames react when released from a drop-tower or even on a parabolic plane flight (25 seconds of weightlessness), which isn't enough to study what long-term damage they can do.
