Outer space has become an increasingly important resource for the Earth. Thousands of satellites orbit the Earth, providing social, scientific, and economic benefits to people on the ground. However, the rapid growth in the space industry poses challenges to space sustainability, which call for international collaborations. Prof. Jean-Paul Kneib, Director, EPFL Laboratory of Astrophysics & EPFL Space Center (Space), will first share his perspectives on the current space industry and his research on sustainable space logistics, followed by Prof. Dr. Shufan WU, Executive Vice Dean of the School of Aeronautics and Astronautics at Shanghai Jiao Tong University, who will share his insights on how space science and technologies contributed to the SDG goals and the general SDG development in China.
