When I saw the earth for the first time, I found it was much bigger than I thought. And I was surprised to see its beauty. I stood at the window for a long time and enjoyed the great sights.

We were very close to the moon. I never saw anything like this. The sun was behind it. It produced a golden haze(薄雾) around the moon. The dark part seemed darker and the light part seemed lighter.

一Michael Collins, America

Floating is wonderful. When I floated, I felt like becoming Superman because I could fly and I could move heavy things around. But when I was eating, it was really hard to play with the food.

There is something you have to do for every spacewalk. When you are out in open space, you have to walk in pairs. You must connect yourself to the station. Or there will be a risk that you would fly away and nobody will be able to bring you back.

—Not yet. I(do) it now.
