A special lecture will be given on the afternoon of December 9 by Shenzhou-13 crew members aboard China's space station. The three astronauts, namely Zhai Zhigang, Wang Yaping and Ye Guangfu, will interact with students on Earth, show them the inside of the Tiangong space station and demonstrate some scientific experiments in the condition of zero gravity. Join CGTN reporter Li Jianhua at the China Space Station Science and Innovation Experience Base for a sneak peek of this space-based lecture.
