Dr. Thomas Zurbuchen discusses research frontiers in space weather. He notes that space weather is as important to space researchers as cancer is to biologists. His presentation covers the role of universities in fundamental research, modeling challenges like the University of Michigan's model, new distributed sensor network architectures using fleets of nanosatellites, and the educational challenge of training students in developing new technologies and analyzing data.
