    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.

      @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

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

    • hernan jimenez
      hernan jimenez

      @Almaadin that was done on 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 😂😂😂😂😂😂😂🤣🤣🤣🤣😭😭😭😭😂🤣🤣🤣🤣😂😭😭

    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!

    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* ?!?!?!??!

  • djmips

    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

    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!

    Hey, I know this video is about the moon, but I have had this question on my mind for a while now, and the recent Mars landing has brought it back again (and I can't think of anyone else to ask) so here goes... This is regarding the 7 minutes of terror: Do you think that it is possible for NASA to build signal amplifiers that would be strategically placed between Mars and Earth, and these would boost the signal enough to reduce the delay in communication time? Or is this still too far in the future? I'm thinking 2 or 3 satellites spaced evenly across the distance whose purpose is to catch and slingshot the signals back and forth... Thank you for your response (provided you get this message, or for anyone else who may have a theory/answer).

    • Atlas

      The delay is because of the finite speed of light. There's nothing that can be done about that.

  • Chinmoy Kathar

    Don't you think the next lander will have highly AI assisted landing if not completely AI assisted landing? Although I agree that manual intervention from the onboard astronauts might be necessary and hence the training on earth is necessary.
