From the photographs sent from the satelites, scientists are learning things about the earth they have never known before.

Because photographs from the satelite are taken looking directly down on the land from such a height, they are more accurate than earlier photographs taken from airplanes.

因为卫星照片是从如此高的地方直接俯视陆地拍摄的，所以它们比以前从飞机上拍摄的照片更准确。
