Dr. John Pojman was the guest for this Space Show program. Dr. Pojman discussed materials and microgravity experiments on the ISS plus the general state of science on the ISS. We also discussed the field of chemistry and its relationship to space. He described "frontal polymerization" which is a reaction that makes plastics or composites propagate as affected by micro gravity. We discussed students and their work in the field, the future of studying chemistry for students and for their role in space development.
