ClassX Video Lessons Youtube Channel SmarterEveryDay How Neil Armstrong Trained to Land on the Moon – Smarter Every Day 250
Welcome to an exciting exploration of lunar landing training, inspired by the Smarter Every Day series. This article delves into the fascinating journey of preparing astronauts, like Neil Armstrong, for the monumental task of landing on the moon. With NASA’s Artemis program reigniting interest in lunar exploration, understanding the technical challenges and historical insights from the Apollo missions is more relevant than ever.
Landing on the moon is a complex task, primarily because of the differences in gravitational pull between Earth and the moon. While Earth’s gravity is 9.8 meters per second squared, the moon’s is only about 1.625 meters per second squared. This means that spacecraft behave differently on the moon, requiring precise control to achieve a velocity of zero upon touchdown.
To prepare for lunar landings, scientists and engineers needed to simulate the moon’s conditions on Earth. In the 1960s, they initially approached the problem using helicopter-like techniques, but these methods had limitations. The challenge was to replicate the reduced gravity of the moon effectively.
NASA developed the Lunar Landing Research Facility (LLRF) at Langley Research Center to address these challenges. The LLRF used a vertical cable system to reduce the apparent weight of vehicles, simulating lunar gravity. This facility provided pilots with a valuable introduction to lunar flight characteristics, although it didn’t fully replicate the experience of flying on the moon.
The development of the Lunar Landing Training Vehicle (LLTV) marked a significant advancement in lunar landing preparation. The LLTV was designed to simulate lunar gravity more accurately and became an essential tool for Apollo lunar module crews. Despite its unforgiving nature, pilots like Neil Armstrong insisted on using it for training, understanding the risks involved.
Conversations with experts like Ben Feist, creator of “Apollo in Real Time,” and Wayne Ottinger, an engineer involved in the LLTV program, provide deeper insights into the challenges faced during the Apollo missions. These discussions highlight the importance of understanding gyroscopic forces and maintaining control during flights.
As we prepare for a return to the moon, it’s crucial to not only build training vehicles like the LLTV but also to comprehend the reasoning behind the decisions made during the Apollo program. This knowledge will guide future lunar exploration efforts.

Hey, it’s me, Destin. Welcome back to Smarter Every Day! This is the first video in a series about returning to the moon. The exciting part is that I don’t yet know what these videos will cover, as the opportunities haven’t fully presented themselves. However, I do know that NASA, with the Artemis program, is focused on lunar exploration, and I’m all in!
If you’re a contractor, program manager, or part of NASA and have insights about landing on the moon, I’m your guy. Just reach out, and we can create a video about it here on Smarter Every Day.
Now, let’s dive into some specific technical challenges that need to be addressed for a safe lunar landing. The first thing to consider is that when a lander descends to the surface of another celestial body, it must achieve a velocity of zero upon touchdown. This was successfully accomplished by the Apollo astronauts, who piloted their craft down to the lunar surface, ensuring they reached zero velocity at the moment of contact.
This may sound straightforward, but it’s quite complex. On Earth, we experience a gravitational pull of 9.8 meters per second squared, while on the moon, it’s only about 1.625 meters per second squared. This difference means that a spacecraft will behave differently on the moon compared to Earth.
So, how do you practice landing on the moon while on Earth? Many scientists and engineers today understand how we went to the moon, but we need to regain insight into the decisions made along the way. This task is well-suited for scientific historians.
Let’s start this series with a notable source on the history of the lunar lander program: a lecture given in 2007 by Neil Armstrong in front of the Society of Experimental Test Pilots.
In January 1962, a free-flight lunar landing simulator program was proposed, consisting of a preliminary study, a research test vehicle, and an Apollo flight simulator. The research test vehicle was designed to investigate lunar descent problems from altitudes of up to 2,000 feet and to vary control characteristics and landing gear configurations.
Neil explained that in the 1960s, they approached the problem of lunar descent similarly to how helicopters operate. However, helicopters have their own challenges, particularly in how they manage weight and lift.
The engineers realized that simulating lunar gravity on Earth was difficult. They explored various vehicles, including experimental aircraft like the X-14, but these did not replicate the effects of reduced gravity effectively.
To address this, NASA developed the Lunar Landing Research Facility (LLRF) at Langley Research Center. This facility aimed to simulate lunar gravity by using a vertical cable system to reduce the vehicle’s apparent weight. Once the kinks were worked out, it provided pilots with a valuable introduction to lunar flight characteristics.
However, the LLRF still didn’t fully replicate the experience of flying. The preferred method became free-flight simulation, leading to the development of the Lunar Landing Training Vehicle (LLTV). This vehicle was designed to simulate lunar gravity and was highly regarded by Apollo lunar module crews.
I spoke with Ben Feist, who created the website “Apollo in Real Time.” He explained that the project took two years and involved syncing every piece of footage from the Apollo 11 mission to the historical record.
The LLTV proved to be an excellent simulator, but it was also unforgiving. Despite the risks, pilots insisted on using it for lunar landing preparation. Neil Armstrong, a test pilot, played a crucial role in developing training protocols for the Apollo missions.
I also had the opportunity to speak with Wayne Ottinger, an engineer involved in the LLTV program. He shared insights about the challenges they faced, including issues with gyroscopic forces and the importance of maintaining control during flights.
As we prepare for a return to the moon, it’s essential to understand not just how to build training vehicles like the LLTV, but also the reasoning behind the decisions made during the Apollo program.
Thank you for joining me on this episode of Smarter Every Day. I hope to explore more about lunar landers in the future.
