Scientist advocates greater cooperation among the stars

A thousand people may have a thousand answers as to why we explore space. For 64-year-old Chinese scientist Wu Ji, exploring space has a more self-reflective meaning.

"When one enters space, one will realize that human beings are an indivisible whole. Regardless of skin color, they have far more in common than they have differences," says Wu, chairman of the Chinese Society of Space Research.

It is under this belief that, for more than two decades, Wu has been persisting in one thing－promoting international cooperation in the field of space science.
