This symposium is the first of a new series of events initiated by COSPAR. It will be held every two years in a different area of the world. This first Symposium aims at promoting space and astronomical research on the theme of “Planetary Systems of our Sun and other Stars, and the Future of Space Astronomy” at regional level, which include multidisciplinary sessions and training sessions. Professional, young professional and students in the ASEAN region and worldwide are encouraged to participate. A capacity building workshop will also be organized during the week before the Symposium.
