Shenzhou XII taikonauts talk with HK students

4: A student from Clementi Secondary School:

Why did you become an astronaut? What do you think is the coolest thing about the job?

Yang Liwei (First Chinese national in space): At first, I wanted to be a pilot. After that dream was realized, I took an interest in aerospace science. Luckily, the nation had launched its manned space projects at that time. I devoted myself to the nation's aerospace development out of my passion and the nation's need, and the country has made improvements in economy, technology and overall strength.

I have come to Hong Kong many times and communicated with many Hong Kong students. From Shenzhou 5 mission to Shenzhou 12 mission, astronauts have shown many work and life-related scenes during each mission. What these astronauts have achieved is all "cool". For me, the coolest moment was when I displayed the national flag and greeted all Chinese people as the first Chinese astronaut entering space.

5: A student from University of Hong Kong:

The microgravity state in space creates a very special environment for doing experiments. Can you tell us about the space experiments conducted in this mission?

Tang Hongbo:

We mainly focus on three areas of study - physics in weightlessness, aerospace medicine and human factor engineering. We take advantage of this precious opportunity to study the special physical phenomena in the weightless environment, as well as various physical and mental effects of space flight on astronauts, so as to find a better way for people to work and live in space. These experiments also help us better prepare for finding an "extraterrestrial homeland" for mankind.
