Explanation: Bright sunlight glints as long dark shadows mark this image of the surface of the Moon. It was taken fifty-four years ago, July 20, 1969, by Apollo 11 astronaut Neil Armstrong, the first to walk on the lunar surface. Pictured is the mission’s lunar module, the Eagle, and spacesuited lunar module pilot Buzz Aldrin. Aldrin is unfurling a long sheet of foil also known as the Solar Wind Composition Experiment. Exposed facing the Sun, the foil trapped particles streaming outward in the solar wind, catching a sample of material from the Sun itself. Along with moon rocks and lunar soil samples, the solar wind collector was returned for analysis in earthbound laboratories.

说明: 明亮的太阳炫光和和颀长的黝黑影子，妆点了这幅月表影像。影像是由阿波罗11号宇航员尼尔·阿姆斯特朗，摄于54年前的1969年7月20日，当时正进行第一次月表漫步。在影像里，可见到此次登月任务的老鹰号月球舱，以及身着太空衣的月球舱驾驶员艾德林，正在开展用于进行太阳风成分实验的长金属薄片。面朝太阳的这片金属箔将补捉向外泛流的太阳风粒子，所以等同于取得来自太阳的物质样本。除了月岩与月球土壤样本之外，这片太阳风收集器也一同回送到地球实验室进行完整的分析。
