离开地球会是什么样子?2005年,信使号宇宙飞船在飞向水星的途中经过地球时,对这一事件进行了非常详细的视觉记录。在这段延时视频中,我们可以看到地球在旋转,因为它正在向远处退去。地球被阳光照射的那一半非常明亮,以至于背景中的恒星都看不见。从2011年到2015年绕水星轨道运行的信使号宇宙飞船首次绘制了水星表面的完整地图。偶尔,信使号还会继续观察它的母星。信使号是地球上为数不多的永远不会回来的东西之一。在任务结束时,信使号撞到了水星表面。

What it would look like to leave planet Earth? Such an event was recorded visually in great detail by the MESSENGER spacecraft as it swung back past the Earth in 2005 on its way in toward the planet Mercury. Earth can be seen rotating in this time-lapse video, as it recedes into the distance. The sunlit half of Earth is so bright that background stars are not visible. The robotic MESSENGER spacecraft orbit around Mercury from 2011 to 2015 has conducted the first complete map of the surface. On occasion, MESSENGER has continued to peer back at its home world. MESSENGER is one of the few things created on the Earth that will never return. At the end of its mission MESSENGER crashed into Mercury's surface.
