And that long tail, the magnetotail, stretches all the way to the Moon.

而那个长长的尾巴，也就是磁尾，一直延伸到月球。

And while it shields the Moon from the solar wind, the magnetotail also flings charged particles from the Earth's upper atmosphere toward the lunar surface.

当它保护月球免受太阳风的影响时，磁尾还将地球高层大气中的带电粒子抛向月球表面。

If you have an instrument like India's Chandrayaan 1 chilling out in lunar orbit, you can measure and compare water formation rates when the Moon is either outside or inside of Earth's magnetotail.

如果你有一个像印度月船一号这样的仪器在月球轨道上冷却，你可以测量和比较月球在地球磁尾之外或之内时的水形成率。
