In the United States, combustion processes contribute about 85% of the energy supplied and are an integral part of many industrial manufacturing processes. Burning produces greenhouse gases and soot, which contribute to global warming and cause significant health problems. The Combustion Science Program conducts idealized experiments on the International Space Station where the elimination of gravity allows researchers to study the details of combustion processes that cannot be easily studied on the ground. The Space Station environment also provides an important test bed for studying spacecraft fire hazards.
