Of the more than 550 people who have been in space, just under 70 are women.

One of the female astronauts is Wang Yaping, who is currently on a six-month mission in space.

- I want all women to be able to aim for the stars and get the career they want, she says.

In China, Wang Yaping is seen as an inspiration to many women.

She is the first woman in the country to make a so-called space walk, a stay that an astronaut makes outside her craft.
