Kylar presented a paper demonstrating manufacture, safety, and firings of potassium nitrate-sorbitol (KNSB) propellant rocket motors for academic purposes. He gave the presentation first thing Monday morning, and then we hung around until I presented my paper on Wednesday. The conference itself covered all kinds of research in aerospace spanning education, CFD, fluid flows, aerodynamics, space research, and some propulsion. Compared to AIAA Propulsion and Energy that I attended in 2018, not as many talks piqued my interest, and Tuesday in particular was one of the slower days. However, a couple of the plenary speakers were fantastic. Dr. Danielle Wood of MIT presented on using space technologies to improve sustainability on Earth and preserving landmarks in our solar system like the Moon and Mars. Dr. Ellen Stofan of the Smithsonian National Air and Space Museum gave a great lecture as well, but on improvements the museum is making and involving more girls and women in STEM (and STEAM). This video narrated by Harrison Ford, is a wonderful promotional piece the museum made on that subject.
