Chinas Shenzhou 21 Astronauts Are Stranded Aboard The Tiangong Space Station
If an emergency arises aboard China’s Tiangong space station in the next few days, its three astronaut residents could be in trouble.
That trio — members of the Shenzhou 21 mission — arrived atTiangongon Oct. 31 for a six-month stay. But their planned ride home is already gone.
On Thursday night (Nov. 13), the Shenzhou 21 spacecraftcarried three different astronautsaway from the station — members of the Shenzhou 20 mission, whose own vehicle was deemed unfit to carry people back to Earth after beingdamaged by a space-debris strike.
China keeps a Long March 2F rocket and Shenzhou spacecraft “in a state of near readiness” at Jiuquan Satellite Launch Center as a matter of policy during crewed missions, asSpaceNews’ Andrew Jones noted. If something goes wrong on Tiangong, this standby lifeboat can be launched to the station as little as 8.5 days later.
That countdown has likely already begun for the Shenzhou 21 crew, as the lack of a safe ride home definitely qualifies as a contingency.
Indeed, Chinese space officialshave already saidthat the Shenzhou 22 spacecraft will be launched to Tiangong (presumably without anyone on board). They didn’t give a timeline, saying only that the liftoff will occur “at an appropriate time in the future.”
But it’s safe to assume that launch day is near; the nation surely doesn’t want to expose its astronauts to any risk than is necessary, and every day spent in orbit without a lifeboat is a risk.
The Shenzhou 21 astronauts’ plight calls to mind the experience of NASA astronauts Butch Wil and Suni Williams, who flew to theInternational Space Station(ISS) in June 2024 on the first-ever crewed mission of Boeing’sStarlinercapsule.
Starliner suffered helium leaks andthruster issueson the way up, and NASA eventually decided to bring the spacecraft back to Earth uncrewed. That happened without incidentin September 2024.
Wil and Williams, meanwhile, continued living on the ISS until this past March, turning a planned 10-day mission into anearly nine-month affair. They eventually came homeon a SpaceX Crew Dragon capsulealong with fellow NASA astronaut Nick Hague and cosmonaut Alexandr Gorbunov.
But the Shenzhou 21 astronauts are in a precarious spot at the moment than Wil and Williams ever were. There were always non-Starliner lifeboats docked to the ISS during the NASA astronauts’ orbital stay, and they could havesqueezed into one of these craftfor a cramped ride home if something had gone terribly wrong on the ISS.
That doesn’t seem to be an option for Tiangong’s current residents: The Shenzhou 20 spacecraft, the only crew-capable vehicle docked to the station at the moment, sports tiny cracks in one of its windows thanks to the debris strike.
“The Shenzhou-20 spacecraft does not meet the requirements for the astronauts’ safe return and will remain in orbit to continue relevant experiments,” the state-run Xinhua news outletreported on Thursdayciting information from the China Manned Space Agency.
Shenzhou 21 is the 10th crewed mission to Tiangong, a three-module station that’s about 20% as massive as the ISS.
The mission consists of commander Zhang Lu, 48, who also flew onShenzhou 15in 2022, and two spaceflight rookies, Zhang Hongzhang and Wu Fei. Wu has the distinction of being the youngest member of China’s astronaut corps.
