The telescope they used was on the ground which meant it had to peer through Earth's turbulent atmosphere.

他们使用的望远镜是在地面上的，这意味着它必须穿透地球动荡的大气层。

They also need enough energy to withstand Earth's turbulent atmosphere, which will be slowing them down and heating them up at the same time.

他们还需要足够的能量来抵抗地球动荡的大气层，大气层会减慢它们的速度，同时加热它们。
