讲座题目:The SMILE Mission - the First-Ever Experiment to Track the Drivers of Space Weather




The joint Chinese Academy of Sciences/European Space Agency SMILE (Solar wind Magnetosphere Ionosphere Link Explorer) satellite mission, scheduled for launch in 2023-2024, will for the first time, track the causal chain of space weather from the solar wind to the upper atmosphere. SMILE will be on a highly elliptic, high inclination orbit with apogee in the solar wind. The satellite will carry magnetic field and plasma instruments to track the solar wind just outside the magnetopause, a soft X-Ray imager to track changes in the magnetopause and cusp in response to the solar wind driver, and a global UV auroral imager to track the geospace response to the dynamic solar wind. The UV imager will be provided by the University of Calgary and the Canadian Space Agency. In this talk, I will provide an overview of the SMILE mission and its objectives, and discuss in depth the scientific objectives of the SMILE UV imager. 



Eric Donovan is a Professor of Physics and Astronomy at the University of Calgary, in Canada. Dr. Donovan's research focus is on magnetospheric dynamics, and in particular how fundamental kinetic-scale processes evolve, through meso-scale (MHD-scale) processes, to have global space weather effects. His research program is organized around developing and operating auroral imaging systems, both ground- and space-based. A central theme in his research is using the aurora to remote sense geospace dynamics at the system level. Together with Stephen Mende of UCBerkeley, Dr. Donovan leads the THEMIS network of all-sky imagers, and he is the Principal Investigator of the UV auroral imager on SMILE.
