Mengtian, the third and final lab module, has successfully docked with the front port of Tianhe, the China's Tiangong space station's core module, at 4:27 am today after it entered the planned orbit, the China Manned Space Agency (CMSA) said. 

The Mengtian module carries a wide range of experimental equipment, including extremely accurate atomic clocks and gear designed to create the coldest conditions ever achieved by humanity. It’s a significant step as China expands her extensive scientific research outside the Earth’s atmosphere.

Congratulations to the Tiangong space station. We wish China every success on her each new mission!
