China launches key module of new space station

Minutes after the launch, the fairing opened to expose the Tianhe atop the core stage of the rocket, with the characters for “China Manned Space” emblazoned on its exterior. Soon after, it separated from the rocket, which will orbit for about a week before falling to Earth, and minutes after that, opened its solar arrays to provide a steady energy source.

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 — 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.

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.

10 more modules, 4 manned spacecraft

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 kilometres.

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 uncrewed probe to Mars and the construction of its own space station.

In contrast, the fate of the aging 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 Washington rise.

Moscow has slammed the U.S.-led Artemis moon exploration program and instead chosen to join Beijing in setting up a lunar research outpost in the coming years.
