HELSINKI — China is set to launch an uncrewed Shenzhou spacecraft to the Tiangong space station to provide the Shenzhou-21 astronauts with a means of returning home.

An airspace closure notice issued Nov. 17 indicates that China is preparing the Shenzhou-22 spacecraft and a Long March 2F rocket for launch at around 11:10 p.m. Eastern Nov. 24 (0410 UTC, Nov. 25) from Jiuquan Satellite Launch Center in the Gobi Desert. China’s human spaceflight agency has yet to publicly announce the plan.

The move comes after the Shenzhou-20 crew needed to use the recently-arrived Shenzhou-21 spacecraft to return home Nov. 14 after space debris damaged their own Shenzhou-20 spacecraft. This leaves the Shenzhou-21 astronauts apparently without a lifeboat in the case of a catastrophic emergency, such as depressurization or fire aboard Tiangong. 

The Shenzhou-21 astronauts—commander Zhang Lu and crewmates Zhang Hongzhang and Wu Fei—launched to Tiangong Oct. 31 in the Shenzhou-21 spacecraft, beginning their six-month-long mission. They were handed control of Tiangong Nov. 4 by the outgoing Shenzhou-20 crew, who were due to depart for Earth the next day after completing their own half-year stint in orbit. That journey was however postponed early Nov. 5 due to the detection of a suspected debris impact which damaged a small viewport window on Shenzhou-20.

Shenzhou-22, originally scheduled to launch the next crew to Tiangong around April-May 2026, will now launch without a crew, according to Zhou Yaqiang, an official with the China Manned Space Engineering Office (CMSEO), speaking to China Central Television Nov. 15. 
  • Zhou stated that preparations were underway and that food and supplies for the astronauts and equipment for the space station would be aboard Shenzhou-22. 
  • The unforeseen extended stay of the three Shenzhou-20 astronauts would have drained supplies and put additional strain on Tiangong’s life support systems.
