Taikonauts of China's Shenzhou-12 mission have met with the press again. It's been almost three months since they came back to Earth. The crew talked about their health condition and announced that they would go back to regular training. Meanwhile, China's space agency says it will be livestreaming the world's first series of classes from space on Thursday. Taikonauts of the Shenzhou-13 mission will be conducting lessons from the country's space station, which they are helping build for the next four months. The Tiangong classes will introduce students to construction efforts and how China's space station operates in orbit. Taikonaut and real-life teacher Wang Yaping was also part of a mission in 2013 that delivered a lecture from space to over 60 million schoolchildren across China via live video-streaming.
