Chinese astronauts face extended stay on Tiangong space station after debris impact

Three Chinese astronauts are stranded on the Tiangong space station after a suspected space debris impact on their return capsule. The astronauts' return was delayed due to potential damage to the Shenzhou-20 capsule, prompting inspections of critical reentry systems. A replacement crew has arrived, leading to an overcapacity on the station. China's space agency has remained largely silent on the incident, fueling speculation and marking a new challenge for its human spaceflight program.
