Watch it again: Chinese astronauts deliver second lecture from space station
Crew members of China's Shenzhou XIII mission are all set to deliver their second lecture live from the orbiting Tiangong space station Wednesday afternoon.
Three astronauts - Zhai Zhigang, Wang Yaping and Ye Guangfu - will open the lecture of the Tiangong Class, or Heavenly Palace Class, which will be broadcast live to audiences around the globe.
The astronauts will carry out four experiments to show physical phenomena in microgravity, including liquid crystallization and water surface tension.
The session will also include a space-Earth talk between the astronauts and the youth, in an effort to inspire students' interest in science and space.
Tune in at 3:40 pm Wednesday to watch the special coverage LIVE.
