On Earth, men are seen as superior because of their physical strength, but it means nothing in space, where there is no gravity.

I'm not sure I have the physical strength to undertake a novel.

I will do my best to support science in Korea and space programs in Korea.

I felt so free in space, flying around and unrestrained by any social relationships, but my life since has changed a lot. Now I am extra-careful about what I say and do because everyone recognises me.

Physical strength in a woman - that's what I am.

If you ask me what's harder, being famous or flying to space, I'd say fame is much harder.
