3月14日，满月穿过地球黑暗的本影，地球上的居民目睹了月全食。当然，从月球近侧看，同样的天文现象被视为日食。在月球表面的危机海上运行，蓝色幽灵着陆器在CDT凌晨3:30左右拍摄了地球剪影的视频帧，就在太阳从地球圆盘后面出现的时候。从“蓝色幽灵”的月球视角来看，地球上的日食观测者所熟悉的美丽的钻石环效应是惊人的。由于从月球表面看地球的大小大约是太阳的四倍，所以在日全食期间，从地球上最容易看到的太阳大气层——太阳内部的日冕就被隐藏起来了。尽管如此，在地球稠密的大气层中，散射产生了环绕着我们美丽星球的发光光带。

On March 14 the Full Moon slid through Earth's dark umbral shadow and denizens of planet Earth were treated to a total lunar eclipse. Of course, from the Moon's near side that same astronomical syzygy was seen as a solar eclipse. Operating in the Mare Crisium on the lunar surface, the Blue Ghost lander captured this video frame of Earth in silhouette around 3:30am CDT, just as the Sun was emerging from behind the terrestrial disk. From Blue Ghost's lunar perspective the beautiful diamond ring effect, familiar to earthbound solar eclipse watchers, is striking. Since Earth appears about four times the apparent size of the Sun from the lunar surface the inner solar corona, the atmosphere of the Sun most easily seen from Earth during a total solar eclipse, is hidden from view. Still, scattering in Earth's dense atmosphere creates the glowing band of sunlight embracing our fair planet.
