Global Dynamics Of The Earth's Magnetosphere: The IMAGE Satellite Mission Jim L. Burch Space Science and Engineering Southwest Research Institute The Imager for Magnetopause-to-Aurora Global Exploration (IMAGE) has obtained the first comprehensive multispectral global images of the Earth's magnetosphere. The two-year IMAGE mission began with launch on March 25, 2000, when the satellite was placed into an elliptical polar orbit with an apogee altitude of 7.2 Earth radii and a perigee altitude of 1000 km. Continuous imaging is performed using (1) ultraviolet emissions from auroral electron and proton bombardment of the atmosphere, from precipitating energetic hydrogen atoms, and from low-energy helium ions in the plasmasphere; (2) neutral atoms produced by charge exchange between magnetospheric ions in three energy bands (10 eV - 1000 eV, 1 - 30 keV, and 20 - 500 keV) and the hydrogen gas of the exosphere; and (3) radio sounding of plasma gradients and boundaries from the ionosphere to the magnetopause. New results have been obtained on (1) the relative global configurations of the electron and proton auroras, (2) the injection and global transport of ions from the plasma sheet during magnetospheric substorms, (3) the global development of the geomagnetic storm-time ring current, (4) the dynamics of the plasmasphere during magnetic storms, (5) a newly-observed neutral atom component of the solar wind, (6) the global outflow of ions from the polar regions triggered by a coronal mass ejection, and (7) interstellar neutral atoms. _______________ Presented at the University of Maryland Physics Colloquium, April 24, 2001
