The Inner Heliosphere at 50 - Parker Lecture

Explore the evolution of our understanding of the inner heliosphere in this 53-minute Parker Lecture from the 2012 AGU Fall Meeting. Delve into the advancements made since Eugene Parker's seminal 1963 publication "Interplanetary Dynamical Processes," examining how our knowledge of solar and heliospheric processes has expanded over half a century. Discover the increased level of detail now available in relating measurements at 1 AU to global solar features across various time and spatial scales. Learn about the progress in understanding space weather, space climate, and their connections to solar conditions. Gain insights into the potential future developments in heliophysics, including the integration of fundamentally unsteady components and their relationships to the solar dynamo. Reflect on how these advancements align with Parker's initial visions and consider the new directions and possibilities that lie ahead for the field in the coming decades.
