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.
MaGaO Před 8 dny
@Almaadin Many Mars probes have crashed. If humans are aboard, it makes sense to train them just in case.

hernan jimenez Před 8 dny
@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 😂😂😂😂😂😂😂🤣🤣🤣🤣😭😭😭😭😂🤣🤣🤣🤣😂😭😭

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.

I wish the U.S still strived to be #1 and invest money into space rather then using our tax dollars to give other countries welfare all the time. It's a shame to think about how far ahead we would be if we were isolationist and reinvested our own money into our own economy.

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.

Nasa openly admits that humans cannot safely travel through the Van Allen Belts.... Yet this problem was solved in 1969-1972. What gives?
Atlas Před 3 dny
@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.
John Doe p144.1
John Doe p144.1 Před 3 dny
@Atlas I hear what your saying but at the same time the moon landing was THE most significant scientific achievement in human history... Wouldn't you think that is something that would be held onto and cherished for generations?
Atlas Před 3 dny
@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
John Doe p144.1 Před 3 dny
@Atlas OK, fair enough. What about the fact that Nasa "lost" over 13,000 reels of telemetry data. Also contributing to the official explanation as to why we haven't been back to the moon.
Atlas Před 3 dny
@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.

The Plan is good! Hopefully it will happen soon! I would like to see human beings will be traveling to the Moon for their vacations and back to the earth! And then Human being will develop the advantage technologies to travel to other planets to live, working, vacation, ...... and back to the Mother Earth!
Nighthawk Před 4 dny
I don't know about you.... but these prototype propulsion techniques, if they were ever snatched by the military and repurposed for military vehicles,.... and IF one, or some, if any, of those prototypes were seen by the public.... there's a really good chance they'd look like flying saucers, to the layman. think about it... 1964 era, middle of the space race, lots of UFO sightings, and now we know that NASA had a *FREAKING VTOL PROTOTYPE* ?!?!?!??!

Am I missing something here? Why wouldn't they try to evenly fill the system with helium compartments or vacuum? Would that be beyond the limit of how much that volume could lift compared to the weight of the lunar lander?

djmips Před 5 dny
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... .
maksphoto78 Před 6 dny
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.

Another great video. It would be interesting to know more about the rocket motor that was on the lander and got it back to the orbiter. I had read something where the NASA engineers made it as simple as possible; without any electrical connections to reduce points of failure. It was basically just a mixing of two (2) chemicals by means of the turning of two (2) mechanical valves. Thanks in advance.

I flew a test device in Grumman hangar 5 over a mosaic set of lunar photos. All I had was a mockup of the LM cockpit. I made 3 test landing attempts for evaluation data. 50 years later I toured the hangar at the Cape Canaveral facility and in an alcove next to the Saturn V rocket was the same unit I tested at the Grumman facility. I worked at Grumman for 30+ years on the A-6 Intruder , the F-14 Tomcat,and The JSTARS . Fun years!
