China Is Now a Major Space Power

With the Tiangong station’s completion, the country has a long-term platform in orbit.

THE SIZE OF the neighborhood in low Earth orbit has now officially doubled. On October 31, China launched the final piece of its new Tiangong space station, completing its construction.

The 18-meter lab module, named Mengtian (meaning “dreaming of the heavens”), enables a range of scientific experiments and now allows the station to accommodate up to six people at a time. It currently hosts commander Chen Dong and two other astronauts.

It’s a significant accomplishment for China’s rapidly growing space program, which plans to build a base on the moon, deploy a lunar rover, and send new landers and orbiters to Mars. It’s also the first long-term neighbor the International Space Station has had since Russia’s Mir station was deorbited in 2001. (China flew two Tiangong experimental prototypes between 2011 and 2019, but they are no longer orbiting.) “This is important for the Chinese space program. The International Space Station won’t run for much longer. You may well end up with only one orbiting space station—the Chinese one,” says Fabio Tronchetti, a space law professor at Beihang University in Beijing and the University of Mississippi.

The Chinese space program plans to have Tiangong last for 10 to 15 years, with the possibility of extending its lifespan, Tronchetti says. The much larger ISS, operated by the United States, the European Space Agency, Russia, and other partners, could be retired as soon as 2030—that’s the end date the Biden administration gave it after extending its mission last year. (Earlier this year, Russia threatened to pull out by 2024, thanks to the ongoing geopolitical tensions that followed its invasion of Ukraine. But space analysts now expect Russia to continue its support until 2030 as well.)……more here
