Voice of America reports, a Chinese astronaut orbiting 340 kilometers above Earth gave a live video lesson on gravity to school children in China on Thursday.
Wang Yaping, China's second female astronaut, is one of three crew members sent to space last week on the Shenzhou-10 spacecraft. VOA says she delivered her lecture from the Tiangong-1 experimental space lab, which China views as a prototype for a full-fledged space station.
Wang participated in a question-and-answer session with students in a Beijing school, adds VOA. She also conducted a series of experiments demonstrating how objects react in zero gravity.
State media said more than 60 million students and teachers were expected to watch the lecture, which is the first of its kind for China, concludes VOA.
