Named after the Chinese goddess of the moon, the Chang'e-5 mission is China's first space mission designed to return lunar samples – and if successful, it will make China only the third country to bring back moon rocks, and the first in almost 50 years. 

The mission seeks to collect around 2 kilograms of samples by drilling to a depth of up to two meters and scooping up lunar surface material. This week on RAZOR, space mission experts explain why it will help our understanding not only of the moon but other planets too.
