神舟出差返回后 “太空鼠”当妈妈啦！

Core Insights - The successful birth of nine baby mice from a female mouse that returned from space marks a significant achievement in China's space research, demonstrating the ability to conduct mammalian space experiments and recover samples [1][2] - The experiment faced challenges, including a food supply issue due to adjustments in the Shenzhou 20 return plan, which required rapid response and adaptation from the ground research team [1][2] Group 1: Experiment Overview - Four experimental mice were launched aboard the Shenzhou 21 spacecraft on October 31 and were housed in a specialized facility on the Chinese space station [1] - The female mouse successfully gave birth to nine pups, with six currently surviving, indicating a normal survival rate [1] Group 2: Emergency Response - The ground research team initiated an emergency response to address the food supply issue, evaluating various potential food alternatives and ultimately selecting soybean milk for the mice [1][2] - An AI behavior analysis system was utilized to monitor the mice's activities, providing critical data for decision-making regarding food consumption [2] Group 3: Research Significance - This mission represents China's first complete process of mammalian space experiments, from preparation to in-orbit experimentation and sample recovery, laying a solid foundation for future large-scale mammalian space science experiments [2] - The research indicates that short-term space flight does not negatively impact the reproductive capabilities of mice, providing valuable samples for studying the effects of space environments on early mammalian development [2]
