"They look amazing in space, as if they are beating," he said, explaining that the beating and gleaming occurred as the living cells had a bioelectrical reaction. Ye showed the students images of myocardial cells observed under a fluorescence microscope. They compared the growth and shape of cells in artificial gravity and zero-gravity, so as to study their changing rules and mechanisms. Ye then demonstrated experiments related to cell growth in the weightless environment in space. According to Zhai, it is called a "penguin jumpsuit" and it has multiple elastic bands inside to help the astronauts maintain their muscle strength. Zhai introduced the special uniform Ye was wearing during the class. She showed the students how to increase their upper limb strength with the bike by putting her hands on the pedals and floating upside down. They use a treadmill, spin bike and resistance bands to stay healthy. Wang said the astronauts may look a little chubby and puffy as the microgravity in space can affect blood circulation. With a water recycling system, every drop of water is made full use of in the space station, she said. In response to a Hong Kong student's question about water, Wang said the water they drink is recycled, noting that there is no difference in taste between regular and recycled water.
She opened the mini-fridge and took out a fresh apple. She showed them the microwave, water dispenser and refrigerator in the space kitchen. Classrooms have also been set up in Nanning in south China's Guangxi Zhuang Autonomous Region and Wenchuan County in Sichuan Province, Hong Kong and Macao.Īssisted by the other two crew members, Wang first gave a tour around, telling students how they go about their lives and work on the space station. The primary classroom is located in the China Science and Technology Museum. It originated some 400 km above Earth in China's space station.Ī total of 1,420 students attended the lecture from five classrooms across China. (Beijing Time) on Thursday and it was no ordinary discourse.
Zhai Zhigang, Wang Yaping, and Ye Guangfu delivered the lecture starting at 3:40 p.m. Three Chinese astronauts' wondrous voices reverberated in the ground classrooms as the schoolchildren listened with rapt attention. The first live class from China's space station was held on Thursday afternoon, given by Shenzhou-13 crew members Zhai Zhigang, Wang Yaping and Ye Guangfu to students on Earth. Students attend a live class given by the Shenzhou-13 crew members, in Kangxian County, northwest China's Gansu Province, Dec.
