I haven't seen aliens (yet) or got 'space sickness'

Being in space for the first time is unusual. Initially, I felt I could not control my body. I couldn't walk, and certain actions just felt weird.

My fellow astronaut, Jing Haipeng, has really helped me adjust, and I'm slowly getting used to the feeling of zero gravity.

I sleep well, but I think that's because we're so busy during the day that I fall asleep as soon as I close my eyes.
