随神舟二十一号载人飞船上行并返回地面 “太空小鼠”成功孕育幼仔

Core Viewpoint - The successful birth of nine offspring from a mouse that returned from space marks a significant milestone in China's space research, demonstrating the feasibility of conducting mammalian space experiments and laying the groundwork for future studies on the effects of space environments on multiple generations of mammals [1]. Group 1 - A female mouse from the Shenzhou 21 mission successfully gave birth to nine pups after returning to Earth, with six currently surviving, indicating a normal survival rate [1]. - The four experimental mice were launched on October 31 and returned on November 14, completing a full cycle of mammalian space experiments, which includes preparation, in-orbit experimentation, and sample recovery [1]. - This achievement establishes a comprehensive technical solution for conducting mammalian space experiments, paving the way for larger-scale studies in the future [1]. Group 2 - Scientists will conduct systematic research on the offspring, focusing on their growth and development, as well as physiological and pathological changes [1]. - Further observations will be made on the reproductive capabilities of the offspring, with the aim of producing a second generation of mice to explore the potential genetic and developmental impacts of the space environment [1].
