A Long March-5B rocket carrying China's second lab module for its space station has blasted off from Wenchang Spacecraft Launch Site on Monday.
This is the fourth mission of the rocket type.
After docking with the space station, the module will be used to carry out experiments about microgravity science, fluid physics, material science and more.
The previous lab module, named Wentian, has been operating for over three months.
China is set to complete building its space station by the end of the year.
