来源：央视新闻客户端 神舟二十号航天员乘组从空间站返回前，按计划，随陈冬、陈中瑞和王杰一同返回的，还有4只实验小 鼠，它们是中国空间站迎来的首批哺乳动物"访客"。4只小鼠雌雄各2只，被安置在专用的小型哺乳动物 饲养装置中。 陈冬：刚开始入轨的时候，我们看小老鼠，它很兴奋，很壮，当时我们就想，地面挑选的确实不一样， 这么胖吗？后来王杰说，是不是它们到天上不适应，身体也发肿啊？因为我们人体上来之后会有点肿， 脸上都充血，脸都变胖了，是不是它发肿了，整个身子都胖了，然后毛发也特别油亮，然后在里面抓着 小栏杆，还在活动，很活跃，当时第一眼看的时候就很亲切。 记者：在地上是很讨厌的东西。 陈冬：一开始里面是有的。它是满足五天回来，食品是做在它那个小笼子里面了。 然而，原本只计划在太空停留5天的小鼠，却因舷窗突发情况，意外开启了长达14天的"太空出差"。而 饲养装置内的食物，却只够维持5到7天的任务所需。 陈冬：我们给它喂水，喂豆浆。 记者：为什么喂豆浆？ 陈冬：因为豆浆通过注水口可以打进去。一开始并没有留喂东西的口。 记者：不给人家吃吗？ 陈冬：那时候真的是没有这个感觉，因为它是做了一个封闭性的，就是五天时间就返回，做 ...
