Wang Jie, Chen Zhongrui and Chen Dong, who were part of the Shenzhou-20 space mission, flew to the Tiangong space station in April. They were expected to return yesterday after a six-month mission, and the Shenzhou-21 crew, who were sent to replace them, had already arrived on the weekend. The China Manned Space Agency said: ‘The Shenzhou-20 crewed spacecraft is suspected to have been struck by a small piece of orbital debris, and assessment of the impact and associated risks is currently underway. ‘To ensure the health and safety of the astronauts and the successful completion of the mission, it has been decided that the originally planned return of Shenzhou-20 on November 5 will be postponed.’ The two crews remain on board Tiangong. A risk assessment is currently underway.

During the six-month missions, the astronauts perform different tasks, including repairing damage to the orbiting outpost. There were no problems reported earlier this week. State media said two crews enjoyed a meal of baked chicken – cooked on the space station’s first oven, which was delivered by the Shenzhou-21 team. On Tuesday, the Shenzhou-20 and Shenzhou-21 crews conducted a handover ceremony. Yu Jun, a science communicator known online as Steed’s Scarf, said a backup plan may be activated if the spacecraft is deemed unsafe to return.

They are in “emergency duty” mode and ready to bring our astronauts home safely if needed.’ China has continued to expand its space programme. It has so far completed 37 flights and six crewed missions – and has plans to land astronauts on the moon by the end of the decade. Chen Dong, the commander of Shenzhou-20, holds the country’s record for the longest time in space with 380 days cumulatively.
