Why is the space station called Tianhe?

The space station in China is called Tiangong, not Tianhe. The core cabin is named "Tianhe" and codenamed "TH".

The manned space station was named "Tiangong" (code name "TG"), also known as "Wei Zi Palace". It is the palace where the Emperor of Heaven lived in China myths and legends, which means to explore the unknown sky and let astronauts "live comfortably in space".

The core cabin is named "Tianhe" (code name "TH"), which means the unity of man and nature.

As a national heavyweight, Tianhe core cabin is the largest and most complex spacecraft in China at present, and it is the "wisdom brain" of the space station.

Tianhe core module is the management and control center of China Space Station, with a total length of 16.6m, a maximum diameter of 4.2m and a launch mass of 22.5t, which can support three astronauts to stay in orbit for a long time and support space science experiments and technical experiments inside and outside the module.
