Unwrapped: Five Decade Old Lunar Selfie

Explanation: 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.

五十年前的月球自拍照

说明: 这是在月表拍摄的最著名照片之一，只不过这张照片经过数位反向。 1969年阿波罗11号着陆在月球之后，拍下了许多照片，包括一幅由阿姆斯特朗为巴兹·奥尔德林拍摄的标志性影像。原始影像不但呈现这个无比荒芜的异星世界，也记录了奥尔德林弯曲面罩所反映的阿姆斯特朗身影。在这幅使用现代数位科技重新处理的主题影像里，除了修正奥尔德林头盔面罩所造成的球面扭曲之外，更特地把这幅著名的照片反向，呈现从奥尔德林视角所见到的阿姆斯特朗。不论如何，因为这张照片是阿姆斯特朗拍的，所以等同于是一张高龄50年的月表自拍照。在上面影像里，左侧有原始的面罩反射影像，而在右上方则可见到悬在月球天空中的地球。此外，老鹰号着落器包覆镀金箔的脚架非常醒目。在接下来的数年里，人类将重启载人登月计划，其中包括由美国国家航空航天局主导的国际合作计划阿耳忒弥斯（Artemis）。
