China launches Shenzhou 22 spacecraft to assist in return of 3 astronauts stranded on space station

China launched the Shenzhou 22 spacecraft on Tuesday to help bring back a team of astronauts after a damaged spacecraft left them temporarily stranded on China's space station.

The Shenzhou 22 will be used sometime in 2026 by the three astronauts who docked on the Tiangong space station on November 1.

Earlier this month, another group of Chinese astronauts from the Shenzhou 20 mission faced a nine-day delay in their return to Earth after their craft's window was damaged. They eventually returned using the Shenzhou 21 spacecraft, which had just carried the replacement crew to Tiangong.

While the three-person crew landed safely on Earth, three of their fellow astronauts on the replacement crew were temporarily left without a guaranteed way to return in case of an emergency.

The Shenzhou 20 spacecraft — the damaged one, which for now remains in space — will be brought down to Earth later and assessed, according to state broadcaster CCTV. The space program determined it didn't meet safety standards for transporting the astronauts.

Chinese astronauts have been carrying out missions to the Tiangong space station in recent years as part of Beijing's rapidly progressing space program, initially building out the station module by module.

China developed Tiangong after the country was excluded from the International Space Station over US national security concerns, since China's space program is controlled by its military.

Tiangong, which means “Heavenly Palace,” hosted its first crew in 2021. It is smaller than the International Space Station, which has been operating for 25 years.
