China’s space program is making impressive progress. The country only launched its first crewed flight in 2003, more than 40 years after the Soviet Union’s Yuri Gagarin became the first human in space. China’s first Mars mission was in 2020, half a century after the US Mariner 9 probe flew past the red planet.
But the rising Asian superpower is catching up fast: flying missions to the Moon and Mars; launching heavy-lift rockets; building a new space telescope set to fly in 2024; and, most recently, putting the first piece of the Tiangong space station (the name means Heavenly Palace) into orbit.
Tiangong is the successor to China’s Tiangong-1 and Tiangong-2 space laboratories, launched in 2011 and 2016, respectively. It will be built on a modular design, similar to the International Space Station operated by the United States, Russia, Japan, Canada and the European Space Agency. When complete, Tiangong will consist of a core module attached to two laboratories with a combined weight of nearly 70 tonnes.
The core capsule, named Tianhe (Harmony of Heavens), is about the size of a bus. Containing life support and control systems, this core will be the station’s living quarters. At 22.5 tonnes, the Tianhe capsule is the biggest and heaviest spacecraft China has ever constructed.
The capsule will be central to the space station’s future operations. In 2022, two slightly smaller modules are expected to join Tianhe to extend the space station and make it possible to carry out various scientific and technological experiments. Ultimately, the station will include 14 internal experiment racks and 50 external ports for studies of the space environment.
Tianhe will be just
