在中国科学院动物研究所实验动物中心，有6只独特的小生命即将迎来"满月"——它们的父母，是曾搭 乘神舟二十一号载人飞船、在中国空间站驻留14天的一对"太空小鼠"。 此前，4只"太空小鼠"于2025年11月14日随返回舱安全着陆，其中1只雌鼠和1只雄鼠在返回地面后交 配，怀孕雌鼠于2025年12月10日6时许顺利产下9只幼崽。目前有6只幼鼠存活，存活率正常；母鼠哺育 行为正常，幼仔活力良好。 "此次任务证明短期空间飞行未对小鼠的生育能力产生明显影响。"中国科学院动物研究所研究员王红梅 表示，小鼠返回地面后完成交配、怀孕并生出后代，为未来进一步研究空间环境对哺乳动物生命孕育的 影响提供了极其珍贵的样本。 随着这窝"太空小鼠后代"在科研人员的精心呵护下茁壮成长，它们的父母在太空"出差"期间的奇妙经历 也吸引了许多公众的注意与好奇：小鼠能否适应太空环境？飞船返回计划调整给小鼠的"出差"带来哪些 影响？它们产仔后有何不同？ 鼠妈妈将小鼠产在"红房子"内。 小鼠在太空中"飘着玩"。 太空旅行的母鼠有更强的"护崽欲望" 在"太空小鼠"返回地面并产仔后，地面对照组的一对小鼠同样生育了后代。科研团队发现了一个有趣的 现象：经历过 ...
