China’s ‘Space Mice’ Return from Shenzhou-21 and Give Birth to Healthy Pups, marking a significant milestone in space biology research. It demonstrates that short-term spaceflight does not impair reproductive health in mammals. The experiment offers valuable insights for future space missions.
In the Shenzhou-21 mission, China sent four mice aboard the spacecraft on October 31. They returned to Earth on November 14, and one female successfully delivered nine pups on December 10. Six of the pups are thriving, and the mother displays healthy, nurturing behavior. The Chinese Academy of Sciences (CAS) confirmed the results, with Wang Hongmei of the CAS Institute of Zoology highlighting the importance of early development in microgravity.
The space mice experiment faced a critical challenge: a shortage of food and water caused by a return schedule adjustment. Ground emergency plan activation helped manage the crisis. Researchers collaborated with astronauts and used an external interface to supply water, while soy milk was selected as an emergency feeding solution after testing astronaut rations. An AI behavior analysis system tracked mice’s movement and eating habits, ensuring survival and proper care.
Researchers will continue observing the space pups to study physiological development and reproductive capabilities. Plans include examining a second generation to assess long-term hereditary impacts in mammals. This space biology study by China demonstrates how short-term spaceflight affects mammalian survival, reproduction, and development, offering lessons for human space exploration.
In conclusion, China’s ‘Space Mice’ Return from Shenzhou-21 and Give Birth to Healthy Pups highlights groundbreaking achievements in space research. The successful births confirm the resilience of mammals in orbit and pave the way for future biological experiments.
