In this Dec. 11, 1963, image, technicians prepare a test subject for studies on the Reduced Gravity Walking Simulator at NASA’s Langley Research Center in Hampton, Virginia. This position meant that a person’s legs experienced only one sixth of their weight, which was the equivalent of being on the Moon’s surface. The simulator was used to study the subject while walking, jumping, or running; it also was used to train Apollo astronauts for completing tasks in the unfamiliar lunar environment.
The effect was quite realistic. When asked what it was like to land on the Moon, Neil Armstrong replied, “Like Langley.”

在这张1963年12月11日的照片中，技术人员正在美国弗吉尼亚州汉普顿的NASA兰利研究中心为一名测试对象进行减重力行走模拟器的研究准备。这种装置使人的双腿只承受六分之一的体重，相当于在月球表面上的引力条件。该模拟器用于研究人在低引力环境下的行走、跳跃和奔跑行为，也被用来训练阿波罗计划的宇航员以适应陌生的月球环境中完成任务。
这种模拟效果非常真实。当被问及在月球上着陆是什么感觉时，尼尔·阿姆斯特朗回答道：“就像在兰利一样。”
