Ulysses:. Exploring the Heliosphere in Four Dimensions

Abstract

Ulysses is the first spacecraft ever to fly over the poles of the sun. Its primary goal is to explore the heliosphere in four dimensions: three spatial dimensions, and time. An overview of some of the recent results from the mission will be presented. Particular emphasis will be given to the changes occurring in the 3-dimensional heliosphere from solar minimum to solar maximum, and their effects on energetic particles and cosmic rays.
