The return of the Shenzhou XX astronauts from China's Tiangong space station has been delayed due to concerns about space debris impact, according to the China Manned Space Agency. The spacecraft bringing the three-member crew back to Earth may have been struck by tiny pieces of debris, prompting an ongoing impact analysis and risk assessment.

• The Shenzhou XX mission comprises commander Senior Colonel Chen Dong, Colonel Chen Zhongrui, and Colonel Wang Jie.
• The crew has been aboard the Chinese space station for more than six months since their arrival on April 25.
• Experts estimate over 100 million pieces of space debris smaller than 1 cm are in orbit, posing significant risks to spacecraft.
