在城市生活的人差不多每天都要乘坐电梯,但你有没有想过坐电梯到太空旅游?也许有一天,人类只要从太空中放下一根绳索就可以将卫星和飞船拉到预定轨道,像玩木偶一样轻松。这种大胆的设想是俄罗斯科学家在20世纪60年代首先提出来的。后来,美国航天科学家进一步对此进行了论证。著名太空科幻小说作家阿瑟·克拉克根据他们的设想写出了《天堂的流泉》一书。在这都科幻小说中,工程师利用最先进的材料建成了一个太空电梯,电梯站设在位于地球赤道上的一个 People living in cities take elevators almost every day, but have you ever thought of taking an elevator to space travel? Maybe someday, as long as humans put down a rope from space, they can pull satellites and spacecraft to a predetermined orbit, like playing. Puppets are as easy. This bold idea was first proposed by Russian scientists in the 1960s. Later, U.S. space scientists further demonstrated this. The famous space science fiction writer Arthur Clarke wrote a book called “The Fountain of Heaven” based on their ideas. In these science fiction novels, engineers used state-of-the-art materials to build a space elevator with a lift station located on the Earth’s equator.
