Magnetospheric Exploration: Basic Research with High Public Purpose

Explore the fascinating world of magnetospheric research in this 56-minute Van Allen Lecture from the 2012 AGU Fall Meeting. Delve into the evolution of magnetospheric exploration, from the pioneering measurements of trapped radiation by J.A. Van Allen to modern satellite observations. Discover the common themes and striking differences in magnetospheric properties across various planetary systems, including Earth, Jupiter, Saturn, and Mercury. Understand the crucial link between basic magnetospheric research and its profound societal relevance, particularly in addressing space weather concerns that impact navigation, communications, and remote sensing. Gain insights into how the study of magnetospheric phenomena illuminates remote astrophysical processes while simultaneously affecting our daily, technology-dependent lives. This lecture offers a unique perspective on the challenges and privileges of conducting research that bridges fundamental science and practical applications in our increasingly interconnected world.
