Millions of students across China watched the live broadcast of the lecture giving by Shenzhou13 crew members in last month. During the onehour class, students learned about the working environment of the space station. Amazing, they observed experiments related to human body movement as well cell growth in the weightless environment. They were so excited to attend such the wonderful live class in which they learned much about space than before.

They have devoted himself to the space exploration though facing high risks. There is no doubt whether their devotion deserves our respect.”
