Key Points:
- On October 15, 2003, Lieutenant Colonel Yang Liwei became the first Chinese astronaut to orbit Earth aboard the Shenzhou 5 spacecraft, marking a significant milestone for China's space program.
- During his 21-hour mission, Yang experienced an unexpected knocking noise on the spacecraft's hull, described as similar to an iron bucket being struck with a wooden hammer, though no external cause was visible.
- This mysterious knocking was later reported by other Chinese astronauts on subsequent missions, sparking various theories but no definitive explanation.
- Experts have ruled out sound transmission in space and physical impacts from external objects, suggesting the noise may result from the spacecraft's structural expansion and contraction due to temperature changes in orbit.
- The true cause of the knocking remains unknown, highlighting that some space mysteries occur close to home rather than in distant cosmic phenomena.
