The public finally got the chance to have their first glimpse of the core of China's manned space station program on Tuesday at Airshow China 2018 in the southern city of Zhuhai.

Seventeen meters in length, the core module of China's space station, "Tianhe," meaning "harmony of Heaven" in the Chinese language, will serve as the control and management center and docking sites of the spacecraft at the station.

It will also be the main venue allowing three astronauts to go about their own business. Designers of China Academy of Space Technology call it "a cozy three-room apartment."
