这是一张最著名的月球照片，但经过了数字处理。1969年，阿波罗11号登上月球，此后不久就拍摄了许多照片，其中包括尼尔·阿姆斯特朗拍摄的巴兹·奥尔德林的标志性照片。原始图像不仅捕捉到了一个陌生世界的壮丽荒凉，而且还捕捉到了奥尔德林弯曲面罩上反映出的阿姆斯特朗本人。进入现代数字技术。在这张特色图像中，奥尔德林头盔的球形畸变被逆转了。结果就是这张著名的照片——但现在从奥尔德林的角度来看，照片上的是阿姆斯特朗本人。即便如此，既然阿姆斯特朗拍了这张照片，这张照片实际上是50年前的月球自拍照。原始的遮阳板反射在左边，而地球悬挂在月球的天空在右上方。“鹰”号着陆器用箔纸包裹的腿明显可见。未来几年人类重返月球的准备工作包括由美国宇航局领导的国际合作项目阿尔忒弥斯计划。

Here is one of the most famous pictures from the Moon -- but digitally reversed. Apollo 11 landed on the moon in 1969 and soon thereafter many pictures were taken, including an iconic picture of Buzz Aldrin taken by Neil Armstrong. The original image captured not only the magnificent desolation of an unfamiliar world, but Armstrong himself reflected in Aldrin's curved visor. Enter modern digital technology. In the featured image, the spherical distortion from Aldrin's helmet has been reversed. The result is the famous picture -- but now featuring Armstrong himself from Aldrin's perspective. Even so, since Armstrong took the picture, the image is effectively a five-decade old lunar selfie. The original visor reflection is shown on the left, while Earth hangs in the lunar sky on the upper right. A foil-wrapped leg of the Eagle lander is prominently visible. Preparations to return humans to the Moon in the next few years include the Artemis program, an international collaboration led by NASA.
