Watch it again: Space class from Tiangong station
Crew members of China's Shenzhou XIII mission are scheduled to give a space-based lecture on Thursday afternoon from the orbiting Tiangong space station to students around the world.
Three astronauts-Major General Zhai Zhigang, Senior Colonel Wang Yaping and Senior Colonel Ye Guangfu-will open the first lecture of the Tiangong Class, or Heavenly Palace Class, which will be broadcast live to audiences around the globe.
They will show viewers how they live and work inside the space station and will then carry out experiments to display interesting physical phenomena in space such as "disappearing buoyancy" and a "water ball". They will also answer viewers' questions at the end of the livestreamed event
Tune in at 3:40 pm, Thursday to watch the lecture LIVE.
