The Magnetospheric Cusps: Structure and Dynamics

(a) Professor Theodore A. Fritz works in the area of planetary magnetospheres and possible Sun-Earth relations. His particular research interests include energetic charged particles, their composition, and the mechanisms by which they are transported and energized within magnetospheres. He has participated either as a Principal Investigator or Co-Investigator in about 20 spaceflight projects such as the International Sun-Earth Explorer 1&2 (ISEE 1&2), the NASA Galileo mission orbiting Jupiter, the NASA Global Geospace Science Polar satellite mission, and the joint European Space Agency/NASA four satellite Cluster mission. In addition to these ongoing data analysis efforts, he is also involved in the development of new or novel instrumentation for use in space to measure these energetic charged particles and in the teaching and supervision of student researchers. (b) Dr. Shing F. Fung is a Space Scientist at the NASA Goddard Space Flight Center, Greenbelt, Maryland, USA. His main research interests are space plasma physics and physics of planetary magnetospheres. He has extensive experience in analyzing space physics data (plasma, magnetic and electric field, wave, and energetic particle) in order to study and model magnetospheric structures and processes. In addition to data analysis and modelling efforts, Dr Fung is also involved in the development of magnetospheric radio-sounding techniques as recently implemented in the radio plasma imager (RPI) on the NASA IMAGE satellite, and in the development of new generation magnetospheric state-based radiation belt models.
