Moon talk before nation's moon walk

It may be just a moon crater to most, but Chinese sophistication demands at least five different ways of referring to it.

And authorities are now looking for the "right term" to claim the Chinese language's stake on at least 18 lunar features, in the latest sign of the country's growing ambition to explore the heavens, and to land on the moon.

That ambition, plus the interest in naming geological sites on the moon, are coming together as the country sets ambitious goals for space.
