SpaceX and Elon Musk are once again being called upon to rescue spacefarers — this time, the Chinese crew of Shenzhou-20, delayed on China’s Tiangong space station after suspected space debris damage. The three-person crew including Chen Dong, Chen Zhongrui, and Wang Jie, arrived in April and were supposed to return in November after a handover with the Shenzhou-21 crew.A Chinese rescue mission is improbable as the Shenzhou-20 crew faces no immediate danger and China could simply launch Shenzhou-22 earlier as a replacement, if needed.The situation is not without precedent. In 2022, a Soyuz spacecraft attached to the International Space Station (ISS) was struck by a micrometeor, and an uncrewed replacement vehicle was launched to ferry the ‘nauts back to Earth.Does China has the capabilities to rescue its space crew?
