China’s space program successfully completed a unique scientific mission after a group of “astronaut mice” safely returned to Earth following 14 days in orbit, officials announced on Saturday.
The mice were part of an experimental biological study aimed at understanding how microgravity affects mammalian physiology, including bone density, muscle mass, and reproductive systems. The mission was conducted aboard a Chinese research module, where high-resolution cameras and sensors monitored the animals’ behavior and health in real time.
Upon landing, recovery teams transported the mice to a specialized laboratory for medical evaluation. Early reports indicate that all specimens are in stable condition, marking the mission as a significant achievement for China’s growing space-biology program.
Scientists say the data gathered could help improve human long-duration space travel, including future lunar and Mars missions. The experiment is part of China’s broader push to expand its presence in space exploration and scientific innovation.
