“生育后代”
用英语怎么说？

In 1983, during the Cold War, American and Soviet scientists worked together. They wanted to answer an important question: Can animals have babies in space? A scientist named Jeffrey Alberts went to the Soviet Union. He worked with a Russian scientist, Luba Serova. They sent ten pregnant rats into space on a Soviet spacecraft. The rats stayed in space for several days and then returned to Earth. The mother rats gave birth to live baby rats. It was the first time a mammal spent part of its pregnancy in space. However, the baby rats had some balance problems. Today, billionaires like Elon Musk want to send humans to live on Mars. But we still do not know how space affects human babies. We need more research to solve these puzzles before humans can live on other planets.

1983年，在冷战期间，美国和苏联的科学家共同努力。他们想回答一个重要的问题：动物能在太空生育后代吗？一位名叫杰弗里·阿尔伯茨的科学家前往苏联。他与一位俄罗斯科学家柳芭·塞罗娃一起工作。他们将十只怀孕的母鼠用苏联航天器送入太空。这些母鼠在太空停留了几天，然后返回地球。母鼠生下小老鼠。这是哺乳动物首次在太空中度过部分怀孕期。然而，这些老鼠幼崽出现了一些平衡问题。今天，像埃隆·马斯克这样的亿万富翁想要送人类去火星居住。但我们仍然不知道太空如何影响人类婴儿。在人类能够居住在其他星球之前，我们需要更多的研究来解开这些谜题。
