China launches Shenzhou-22 to rescue stranded taikonauts from Tiangong space station

China will launch an unmanned Shenzhou-22 spacecraft to its Tiangong space station to retrieve three stranded taikonauts. The taikonauts from the Shenzhou-21 mission are unable to return home after their intended spacecraft, Shenzhou-20, was damaged by space debris. They have been awaiting rescue for three days. This incident follows a similar situation with NASA astronauts on the International Space Station, highlighting the need for dedicated space rescue services.
