Chinese scientists are planning to use the country's new space laboratory to conduct over a dozen advanced experiments in space.

They are going to use the world's first in-space cold atomic clock to measure time more accurately, and increase the precision of navigation systems here on earth.

Scientists will also test a quantum communication system that relays encrypted information between the space lab and stations on the ground -- that will be impossible for third parties to hack. 

A materials lab on the Tiangong-2 will take advantage of zero-gravity conditions to test 18 new-age composite materials that will be used in future products.
