We might have to wait a bit longer to build that space elevator, although that's clearly a challenge this 'wonder material' was never really going to solve on its own.

我们可能需要再等一段时间才能建造太空电梯，尽管这显然是这种“神奇材料”永远无法自行解决的挑战。

Unlike an Earth space elevator, which is currently science fiction, there is a simple yet promising technology that does not require new science, magic materials, or huge investments, and that has been tested successfully in orbit already.

与仍然停留在科幻阶段的太空电梯不同，有一种更简单且更有潜力的技术，它不需要新的科学发现，魔法或巨额投资，并且已经在地球轨道上测试成功。

A space elevator is pretty much exactly what it sounds like: get onto an elevator car, press the " up" button, and then exit when you've reached the top floor somewhere around 26,098 miles above the Earth .

太空电梯几乎就是字面的样子：进入电梯轿厢，按下“向上”按钮，然后到达顶层，走出电梯，你就来到了地球上方约 26,098 英里。
