China has launched an unmanned module containing what is set to be the living quarters for three crew on a permanent space station that it plans to complete by the end of 2022, state media reported.
The module, named “Tianhe”, or “Harmony of the Heavens”, was launched on the Long March 5B, China’s largest carrier rocket from the Wenchang Space Launch Centre on the southern island of Hainan.
Tianhe is one of three main components of what would be China’s first self-developed space station, rivalling the only other station in service which is the International Space Station (ISS). The ISS is backed by the United States, Russia, Europe, Japan and Canada. China was barred from participating by the United States.
“(Tianhe) is an important pilot project in the building of a powerful nation in both technology and in space,” state media quoted President Xi Jinping as saying in a congratulatory speech.
China’s space station plans
Tianhe forms the main living quarters for three crew members in the Chinese space station, which will have a lifespan of at least 10 years. The Tianhe launch was the first of 11 missions needed to complete the space station, which will orbit Earth at an altitude of 340 to 450 km (211-280 miles).
In the later missions, China will launch the two other core modules, four manned spacecraft and four cargo spacecraft.
Work on the space station program began a decade ago with the launch of a space lab Tiangong-1 in 2011, and later, Tiangong-2 in 2016. Both helped China test the program’s space rendezvous and docking capabilities.
China aims to become a major space power by 2030. It has ramped up its space program with visits to the moon, the launch of an non-crewed probe to Mars and the construction of its own space station.
Russia detaches itself from ISS
Meanwhile, the fate of the ageing ISS, in orbit for more than two decades, remains uncertain. The project is set to expire in 2024, barring funding from its partners. Russia said this month that it would quit the project from 2025.
Russia is deepening ties with China in space as tensions with the US rise. The country has slammed the US-led Artemis moon exploration program and instead chosen to join China in setting up a lunar research outpost in the coming years.
