NASA Langley and the Space Race

When the United States set a goal of landing a man on the moon, NASA Langley Research Center tackled the many challenges of spaceflight, trained astronauts, managed Project Mercury, and assumed major roles in both the Gemini and Apollo programs. Langley led the Lunar Orbiter initiative, which not only mapped the moon, but chose the spot for the first human landing. Langley aerospace engineer John Houbolt championed the lunar-orbit rendezvous concept, enabling the Apollo 11 moon landing and the safe return of its crew to Earth.

Neil Armstrong, the first human to set foot on the lunar surface, trained at Langley's Lunar Landing Research Facility on equipment that cancelled all but one-sixth of Earth's gravitational force to match that of the moon's. This photograph shows Armstrong at the Lunar Landing Research Facility on Feb. 12, 1969. Twenty-four astronauts practiced touchdowns at the facility, where overhead cables supported five-sixths of the weight of a full-size model lander, and thrust was provided by a working rocket engine.

Part of the landing facility was the Reduced Gravity Simulator, which was attached to an overhead, lightweight trolley track. There, suspended on one side by a network of slings and cables, an astronaut's ability to walk, run, and perform the various tasks required during lunar excursions was evaluated.

Armstrong offered what was perhaps the greatest tribute to the importance of his Langley training in Apollo 11's success. When asked what it was like to land on the moon, he replied: "Like Langley."

NASA兰利和太空竞赛

当美国设置登月一个人的目标,NASA兰利研究中心攻克了许多挑战太空飞行,宇航员的培训,管理水星计划的,并假定在这两个双子星和阿波罗计划的主要角色。兰利率领的月球轨道运动计划,不仅映射了月球,而且选择了第一次人类着陆的地点。兰利航空工程师约翰·霍伯特(John Houbolt)主持了月球轨道交会的概念,使阿波罗11号登陆和船员安全返回地球。

尼尔·阿姆斯特朗(Neil Armstrong)是第一个踏上月球表面的人,在兰利的月球着陆研究机构训练设备,取消了地球重力的六分之一,以匹配月球的重力。这张照片在1969年2月12日在农历登陆研究设施上展示了阿姆斯特朗。二十四名宇航员在设施上练习达阵,其中架空电缆支持全尺寸模型着陆器重量的六分之六,推力由一个工作火箭发动机。

着陆设施的一部分是减速重力模拟器,它连接在一个架空轻便的手推车轨道上。在那里,吊索和电缆网络一侧悬挂,宇航员在月球游览期间步行,跑步和执行各种任务的能力得到了评估。

阿姆斯特朗提出了对阿波罗11号成功的朗利训练的重要性。当被问及如何登陆月球时,他回答说:“像兰利一样。”
