I had to find a lot of archival footage to make this video. Thanks to Devin for helping me find the original Apollo LLTV footage from Ellington.
A special thank you to steveslater1987 for providing the footage and audio of the Neil Armstrong Interview after flying the LLTV.

We're going back to the moon, and we're going to need to train Astronauts how to land. This video is the result of trying to understand that control problem better. in the next video of this series, I'll show you footage from an actual NASA Lunar Lander software test I participated in many years ago. Also, I'd like to say express grateful I am to everyone who supports Smarter Every Day on Patreon at www.patreon.com/smartereveryday .

@MaGaO true, but the software to land reliably is fairly new and getting better all the time. Most of the failed Mars landings happened without the benefit of the sensors and algorithms available now. It's still best to train the pilots of course.

@Almaadin Many Mars probes have crashed. If humans are aboard, it makes sense to train them just in case.

@Almaadin that was done on earth..so gullible lol. Mars supposedly is 1% density of earth atmosphere. which means no air. an you need air to slow parachute and need air for lift when they eventually fly helicopter drone. so the impossible without air debunks your Mars landing 😂😂😂😂😂😂😂🤣🤣🤣🤣😭😭😭😭😂🤣🤣🤣🤣😂😭😭

You are one smart dude, there is no doubt, and I love your videos. You posses a very down to earth way of explaining topics that is very appealing. But, I want to offer some friendly advice on the use of the phrase "for free". You cannot give or get something "for free". Inserting the word "for" implies that you have something called "free" that you can give or get in exchange for something. So, first you have to give or get something called "free" before the transaction can take place. Can't be done. The proper way to phrase it would be to simply say "I'm giving you something "free". It's proper and it sounds correct, because it is. Growing up in a family full of teachers has made it impossible for me to let this egregious misuse of the phrase impossible to ignore. However, nearly everyone misuses it, so don't feel too bad. :-} Next up will be my rant on the overuse of the word "basically", which basically has no basic meaning and is nothing more than a basic filler word. There, I feel much better now... Hey, maybe I should start a channel of my own.

But if NASA can program a robot to drop another robot on Mars all on its own. Why do astronauts need to land on the moon on their own? Is it not safer to use the programming? No atmosphere seems like it would create a very consistent and reliable medium to program for, then you don't need to add the possibility of human error in landing.

Goes to show you how much we take all of the technical tools for granted. I imagine engineers will pre-program all of the error correction techniques in a computer for the re-return, but the Apollo crew never had that. They had to do everything with mechanics and training. I think it will be much less of a technical challenge on each individual person, but still a staggering engineering feat overall.

how much would be saved in fuel weight if the rocket first stage was accelerated on a maglev ramp before first stage engine ignition? seems like maglev trains are similar sizable payload can be accelerated to high speeds using electricity and starting a rocket to escape velocity from maglev speeds would have a huge impact compared to starting from a standstill

I absolutely love this video!! My Grandfather was a Quality Control Engineer with NASA and worked on every APOLLO mission!! My Grandfather oversaw the manufacture and installation of the battery systems of the lunar lander! A secret my Grandfather told me before he passed afew years back was. Before they affixed the housing of the batteries, my Grandfather and his crew had a bronze plaque made with their names inscibed on it. They attached it to the top of the housing that covered the batteries!!!! This could have caused a mass firing event if they were caught!!! So now my Grandfather's name is on the moon! This I am very proud of! Just thought you might like to hear the story.

Atlas پیش 4 روز
@John Doe p144.1 The most important bits, like video and audio, sure. Telemetry, not so much, unless of course you're dealing with a severe malfunction, like in Apollo 13. In that case, keeping the telemetry tapes makes sense, and they did.

Atlas
Atlas پیش 4 روز
@John Doe p144.1 It's a shame they lost the original tapes. But I supposed it made sense for them to be erased, since the video signal had been archived elsewhere and keeping telemetry around isn't standard.

@John Doe p144.1 Not really. The rocket used in the Apollo program is no longer manufactured. The last Saturn V was made nearly half a century ago. Can't send people beyond LEO without a a massive rocket.

What actually happens on the moon landing(s) low-key confirmed by his guest Ben Feist is that the Apollo Guidance Computer (AGC) does all of the flying until final approach where Armstrong and other astronauts use the rate-of-decent mode (P66), a mode not unlike drones for the home market where the stabilization is handled by the AGC and Neil uses the fly by wire stick to control horizontal velocity, avoid a boulder field and then bring bring the horizontal velocity to zero; another two switches can speed up or slow down the computers rate of descent in increments of one foot per second. I know the LLTV also had a computer. How similar was it's stabilization and controls to the actual LEM and the AGC's P66?

Well done video, learned a lot, (like there are still people that think we didn’t go to the moon, and the earth is flat. I’m sure there are still those that think Hitler didn’t murder millions of people in death camps...) My question is, why go back to the moon? What’s there that we can benefit people? It will cost billions of dollars, tax dollars, just to say we can it? It’s a moon with ... not much on it. The distances to leave our solar system to anyway else are just too far away. Sorry, this isn’t Star Trek, or some other fantasy TV show... .

Nah uh, they didn't "make sure velocity is zero when touching the surface". They had probes sticking out of lander which, when the probes touched the surface, automatically shut the engine down (while still some meters above the ground), so the lander gently dropped to the ground.

Destin, I have a friend who has an LLTV sitting in his shed at work. I was fortunate enough to get a tour of his "work" and I can honestly say as much fun as it looks... yeah, no... His work is the same AFRC mentioned in your video. I was most impressed by the Peroxide thrusters mounted on every corner and axis of the unit. A tour of the Armstrong facility was the most incredible thing I have had the opportunity to experience. if you are ever there ask about the LLTV and perhaps they can take you to the closet for a look see. God Bless you man, I love your take on science.
