On July 20, 1969, the Apollo 11 astronauts landed on the Moon and began performing the first mission ever to take place with human beings on another world. The year prior, Neil Armstrong, holding the camera here, was almost killed in a test flight accident.With his"great leap forward for mankind," Neil Armstrong achieved one of the most ambitious dreams ever attempted by humans.
By 1965, NASA scientists had determined what an optimal trajectory would look like for safely landing on the Moon. Only the Lunar Landing Research Vehicle , built explicitly for this purpose, was capable of simulating such a trajectory here on Earth.There was no computerized guidance or high-resolution maps of the lunar landing site.
Earth's surface gravity is six times as powerful as the Moon's, meaning that to simulate landing on the Moon, a special vehicle would need to be designed. The Lunar Landing Research Vehicle had a special gimbaled engine, which could maintain effective approximate lunar gravity, enabling the pilot to tilt the vehicle and test its responsiveness under conditions that would simulate landing on the Moon.
