Last week, news emerged that the Shenzhou-20 spacecraft docked to China’s Tiangong space station had sustained serious damage, likely due to space debris. The Shenzhou-20 spacecraft is out of commission as it “does not meet the requirements for the astronauts’ safe return,” per a statement by the China Manned Space Agency (CMSA). It’s also reminiscent of the time NASA astronauts Barry Wilmore and Sunita Williams were stranded on board the International Space Station for eight months longer than anticipated last year. (Instead of their ride sustaining damage due to space debris, their return was delayed by technical issues plaguing Boeing’s Starliner spacecraft.) When the currently orbiting crew will return or whether the Shenzhou-20 is safe enough for a shelter-in-place maneuver remains unclear.
