月球附近是什么？这是国际空间站（ISS）。虽然国际空间站看起来在月球附近，但它不是——它在地球附近。在近地轨道上，国际空间站每90分钟绕着我们的蓝色大大理石旋转一圈，当它几乎在月球前面穿过时，它被照片捕捉到了。月球本身绕地球运行一个月的轨道，在地球上只能看到它被太阳照亮的那一半的弯曲的一小部分，呈现出新月的阶段。这张特色图片是3月下旬在中国上海拍摄的，它不仅展示了地球上最大的人造卫星的细节，还展示了地球上最大的天然卫星上坑坑洼洼的贫瘠表面的细节。在接下来的几年里，人类计划将比以往更多的人和机器送往月球。

What’s that near the Moon? It’s the International Space Station (ISS). Although the ISS may appear to be physically near the Moon, it is not — it is physically near the Earth. In low Earth orbit and circulating around our big blue marble about every 90 minutes, the ISS was captured photographically as it crossed nearly in front of the Moon. The Moon, itself in a month-long orbit around the Earth, shows a crescent phase as only a curving sliver of its Sun-illuminated half is visible from the Earth. The featured image was taken in late March from Shanghai, China and shows not only details of Earth's largest human-made satellite, but details of the cratered and barren surface of Earth's largest natural satellite. Over the next few years, humanity is planning to send more people and machines to the Moon than ever before.
