Dewdrop, the surface layer of dust will leave footprints, and will be blown by rocket blast. However, underneath the first inch or two is a layer of much more compacted regolith and rock. And, they didn't easily put the flag pole into it either. It took a lot of effort.

Love your channel.I found it through a link from a hang gliding site.I had a thrill of a lifetime meeting Neil, Mike and Buzz at the National Air and Space museum at a ceremony commemorating the 15th anniversary of Apollo 11.I was staring into the Columbia when a man stood next to me. Without seeing who it was I said that it must have been something to have been able to fly in that. When the answer was, "It certainly was.", I got to shake the hand of one of my heroes. Neil then took me around and introduced me to the rest of the guys. I was a young aerospace engineering major with dreams of following in their foot steps. Less than a year later an eye injury took me out of flight status with the Air Force. Not being able to fly I left the aerospace world. That was a major mistake!

Many people through out the years have mentioned that the moon was made of cheese. This has been mostly a myth however the truth is that just the interior is made of cheese the surface is made of a milky type substance. Neil Diamond when he landed on the moon sang us a song about how good it tasted. You have heard of moon pies, right? Now you know everything science has learned. In order to learn more we have to go again to the moon again but NASA has lost all the data tapes and pictures so we'd just be doing it all over again from scratch. Nobody likes to do work over again and only get credit for doing it once. One great singer, Frank Sanatra sang a song that went like this, "Fly me to the moon and let me play among the stars. Let me see what things are like on Jupiter and Mars." No one at NASA ever let Frank go to the moon, why? It's hard to say, maybe because of his age or maybe because he drank too much. You can't be drunk and be an astronaut, that place is taken by Buzz. In fact that is how he got his name, Buzz, get it. It took me a while too but I laughed and laughed pretty damned funny isn't it. No much is funny about the moon unless you are talking about the moon car and why even the astronauts The rest of the facts about the moon and astrophysics can be found out by googling Jake the Flat Earth Asshole, He puts out great videos that will aid your search greatly. Good luck and never let a good lie lay.

1:41 "Pounds of thrust feel less under less gravity" Are you really shure abou that one? I mean when you have exhaust velocitys measued in km/s I think the small portion gravity adds to this is negligible... EDIT: Actually gravity doesn't add anything to this at all, because it doesn't influence the relative velocity of the exhaust to the space craft.

When calculating trust, the force of gravity is factored in. The force is actually in Newtons, which are the same anywhere, but you multiply it by the local force of gravity to translate that into pounds. Pounds tend to be easy for people to picture in their minds, so that's why it's used.

Hi White There were two separate engines on the Lunar Lander. The descent engine and the ascent engine. The descent engine got them to the surface and that was all she wrote; never used again. The ascent engine used the descent stage as a launching pad. This is why the complete craft is so tall -- it's really two separate spaceships. Neil Armstrong manually took control of the landing from the computer, because the computer didn't know about the enormous boulder-field it had been programed to land them in. In flying beyond it, he used an enormous amount of fuel reserve, so when he finally touched down, they only had about 40 seconds of fuel left. But the ascent engines were still full.

Amy, you are THE best! Great explanation... I'm old enough to remember when Surveyor touched down (sending pictures while it did so!) there was concern the surface would be covered so thickly in dust, the thing might just sink out of sight. Surveyor's successful landing ended that theory as dust disappeared but the landing was "solid". You'll know this from memory, but I think it was Apollo XII that landed next to that site and brought back a few pieces of it.

An F-35 fighter makes 43000 lbf of thrust which is like 4x the thrust made by the descent stage during vertical landings. And despite that it hasn't blasted any crater I've seen. That's simply not enough. But they did kick up tons of dust. To truly blast a crater you need something with the power of a Starship. Now that was an actual groundbreaking launch.
@critthought2866
@critthought2866 Жыл бұрын
Great points, although one addition. The LM descent engine was throttled down to less than 30%, so the F-35's engine actually pushes at more than 10x what the descent engine was running at. And as you said, even that engine doesn't gouge holes, and it has the advantage of trying to do so in an atmosphere, which keeps the exhaust contained in a column. The LM engine didn't have that. It's a pity that the deniers don't understand what you wrote, but then again if they did they wouldn't be deniers.

I recall an incident several years ago in which a man argued that astronauts cannot possibly manipulate objects on the moon because in a vacuum their gloves would swell up like balloons and become too rigid to move. He then demonstrated this by putting a simple rubber glove in a vacuum chamber (with the open part of the glove sealed to the wall of the chamber) and pumping the air out of the chamber. I found this hilarious because A) astronaut gloves are far more complex than simple rubber gloves and B) if true this would debunk every space walk in low-Earth orbit.

All that remains is the layer of compacted regolith and rock underneath. You see radial striations. OBVIOUSLY "disturbed." But, some internet dummies said the surface wasn't disturbed, so that's what you went with. You never verified this for yourself. YOU SAID: "but the footprints are so we'll defined with no lubricant to hold the form." Pffftttt. The conspiratards love to compare lunar dust to beach sand, expecting the same behavior, that dry sand won't form crisp footprints, but lunar dust does, therefore the moon photos are faked, and/or they think there should be a wet substance to help hold the sand together. But, the lunar dust isn't beach sand. It's not the same thing at all. Here's an example of lunar dust: factsc.com/wp-content/uploads/2017/07/Lunar-Dust-Under-Microscope.jpg It's very jagged and has lots of angles and stuff sticking out, very easy to catch together with other pieces of lunar dust (especially in 1/6th gravity), and is able to hold its shape. Here's an example of beach sand: static.independent.co.uk/s3fs-public/thumbnails/image/2015/11/10/16/Seychelles%20caramel_0.jpg Millions of years of the churning of ocean surf smooths the edges of the beach sand, so they are far smoother than moon dust. Beach sand cannot hold a footprint shape very easily. It's too smooth. The Soviets even sent unmanned probes to the moon that scooped up some lunar dust and brought it back to Earth. Guess what; same exact properties as the Apollo samples. See, this is the problem with you conspiratards: you think you have all of these "gotcha" moments. But, not a single one of you knows what you're talking about. You're completely ignorant of the sciences that you're blindly rejecting. And, in amazing irony, you people always assert that OTHERS are not skeptical enough. Meanwhile, you'll swallow every stupid claim that supports your delusion, with no scrutiny whatsoever. Who's the gullible one here? Who's the one who isn't skeptical enough? You blindly swallowed these dumb concepts that the lunar dust wasn't disturbed under the landers, and that the lunar dust should behave like beach sand. Both of those concepts are easily dismissed by just a few moments of scrutiny. But, if the conspiratards' claims support your delusion, you don't scrutinize them at all. You blindly accept them as "fact," no matter how wrong they are. No, dummy, we're not the ones who lack skepticism. You are.

On Apollo 11 you can hear Buzz Aldrin say the first word ever spoken on the moon. "Contact". Hanging from 3 of the four support leg pads were 2-meter long electric wire-like contact probes. When the first probe touched the moon a blue light lit the LM's instrument panel. At that moment Aldrin said: "Contact light". Neil Armstrong hit a large button that shut off the descent engine 2 meters above the Moon's surface and the LEM gently dropped down on collapsible legs. Armstrong landed so softly, the extension gear on the LM did not fully depress making a long first step from the bottom rung of the ladder to the surface. The touch down was a "greaser". The surface where Apollo 11 landed was extremely hard making it difficult to hammer down to insert the Flagpole. About 7 feet above the moon's surface before the descent engine was cut off, the dust was blown away from under the engine nozzle exposing a hard table-top like surface. Most dust was blown away before it could settle on the footpads by the wide plume of the engine blast before the pads hit the surface. This explains not only why there was a very small if any landing crater, but also why there was no dust on the footpads. See: "Rocketmen" by Craig Nelson for a review of Apollo 11 approach and landing.

I'd appreciate it if you could provide us with some written data on that. Maybe a NASA certified transcript. Or a video of Neil or Buzz saying so. I admit that when you hear Aldrin say "Contact light" it takes a second or two for Armstrong to confirm engine stop, but that doesn't prove anything. Neil could have simply delayed his confirmation that the engine was shut down. Or, the engine was indeed cut off a second after confirmation of light making it 5 ft. Or, Armstrong was "hovering" at the contact light level for a second or so before he cut off the power.

Neil Armstrong has said that he left the engine on all the way to touchdown. Also, in a lot of these videos, there are a couple of other guys who post a lot, who had posted the exact engine shutoff time for each mission (how long before or after touchdown), and the source of that data. Now, the problem is that I've watched so many interviews... it's doubtful that I'd remember which one(s) of those interviews included those comments. But, I'm pretty sure it didn't come from any time I've spoken to the astronauts myself, so yeah, it's probably in videos that you can find online. And, well, scrolling back through the comments to find the exact comments about that... yeah... that will take a while. But, for grins, I just googled the phrase "neil armstrong left engine running until touchdown," and a few entries down on the list, you can find the quoted words, "As we approached the ground, I still had a left translational rate which made me reluctant to shut the engine off,' Neil Armstrong is quoted as saying in the annotations to the radio report. `We actually had the engine running until touchdown."" You might try to dive into that. This was the first time I've seen that quote... my knowledge of this came from elsewhere... but it's a nice source to answer your question, maybe?

Also, by the way, side note, it's pretty unlikely that they'd hover after the contact light. I mean, ok, it's possible. But, keep in mind, the throttle didn't work the way most people think. It was really just a selection of how fast you want to descend, in feet per second increments. If you're coming down at 10 feet per second, you click 3 times, and it lowers your descent rate to 7 feet per second. Click 5 more times, and the computer lowers your descent rate to 2 feet per second. They didn't use a throttle lever like an airplane. You told the computer what descent rate you wanted, and it did the calculations, because with the fuel draining so quickly (lightening the load every second), and in 1/6th gravity, it would be really easy to accidentally ascend instead of descend. So, instead, they built the system so that you told the computer what descent rate you wanted, and it did the calculations for what exact throttle should be used for the remaining weight. If I remember correctly, the LEM burned 18,000 pounds of fuel on descent (double check this, please). So, a throttle position of [whatever] would have a dramatically different effect every second that went by. So, they computerized that part. Bottom line: it's pretty doubtful that Armstrong would put the thing back into "hover" (0 feet per second descent rate) after the contact light was on. Not that it wasn't possible. I just don't think so, and the video doesn't support that idea either.

Rockethead7: I find this an interesting topic because it involves one of the most, if not the most momentous accomplishment by human beings. It's amazing to watch and listen to the Apollo 11 audio and video. It never gets tiring. I just want to know more about the details of the last minute before touchdown. If you state you've seen or heard videos where Armstrong or Aldrin stated they kept the power on until or almost until touchdown, I have no way to argue with you. That is why I wanted to see something that describes the event. I've heard that Armstrong touched down so softly the legs on the LEM did not fully compress thus making the last step on the ladder to the surface extra high. Maybe that's because he touched down with power. NASA didn't want that because they were afraid the thrust plumb might reverse back up into the engine and cause problems. Also, it was widely assumed there were about 17 seconds of fuel remaining after touchdown of the Apollo 11 LEM. I heard later that NASA recalculated the amount of fuel and determined there were about 40 something seconds left. To this day I still don't know because I see conflicting answers. Many people will say "who cares"? Well, I do as a matter of history and space science and as one of the millions of young kids back in the day who wanted to become astronauts. As far as the hovering issue, it's not that far out. When Armstrong took over part of the autopilot system and manually flew over the crater and boulder field, his flight path actually took the LM from a descent to level flight to a slight climb before he began to descend again. So it wouldn't be a far stretch for him to have hovered for a second or two just after Aldrin called "contact Light". But I have no proof for this at all and I don't want to start a rumor. I'd really like to see a reference to the video where Armstrong describes the final touchdown. I'm going to try to find it. My hope is someone will direct and describe how high the LEM was when the engine was cut off or how much fuel was really left in the tanks after touchdown. If I come across any evidence, I'll be sure to post it here. I hope you will do the same. Be well.

Yes. considering gravity alone, lower gravity would mean that dust would get kicked up farther and be slower to come back down. But the lack of atmosphere means that even the smallest speck of dust would come back down at the same rate as a giant boulder. Even if one kicked dust up 100 meters (330 feet) it would all be back on the surface about 22 seconds after getting kicked up. Getting prepped to get out of the lander would give plenty of time for any dust kicked up by the landing to fall back to the lunar surface.

I will have to disagree with you on this one. I think if you look at the photos you can actually see the blast crater. It is very shallow as the pressure was very low, probably comparable with a helicopter landing on a beach. If you look at photo AS11-40-5921 you can see ray like effects from the engine and in AS11-40-5864, and AS11-40-5892 you can see the effects of the exhaust plume. You would only expect a crater a couple of inches (~5cm) deep and that is what one can see.

+1978ajax Let us be honest, the primary problem with StJohns River66's argument is he (?) starts with a bad assumption. And as we know, assumption is the mother of all F@#k ups. StJohn assumes that dust will behave the same on the Moon as it does on Earth. However the Earth has an atmosphere and the Moon does not. On the Earth one would expect that the dust would be kicked up, the atmosphere would slow it down. The dust would be suspended in the air near the landing for seconds to hours and the wind would blow it onto the pads. On the Moon, when the dust is kicked up, it is thrown away from the lander in projectile motion. There is no air to slow it down and it will settle at a distance from the lander. There will be no dust to settle on the pads. So StJohns River'66's argument comes down to "The dust on the moon did not act the same way it would on Earth, therefore this is absolute proof that this was been done of Earth". To you and me, this is a nonsensical argument and is actually further proof that humans landed on the Moon. But to StJohns, who appears to be incapable of critical reasoning or rational thought, this is absolute proof that the Moon landings were faked. Either that or he is a poor troll.

If you notice a SpaceX launch, you can see the thrust plum get wider as the rocket reaches the upper atmosphere. For the same reason explained in this video, the less ambient air pressure the wider the exhaust plume. On the moon, the exhaust plume with a throttled back engine would be much wider than the same plume at sea level on Earth. Just notice any rocket launch as the engines hit the outer atmosphere. Another reason why there is little or no crater from the LM on the moon. Depending on where the LEM landed determined the nature of the blast crater. Some Apollo landing surfaces were harder than others.

The thrust of the LM engine is a 3000lb spread over several hundred square feet not inches. The engine shut down 10 feet above the lunar surface (if you look at the landing footage you can see the probe rods shadows below the landers pads). The forces involved were like a one foot drop on earth cushioned by the struts compressing. The gas forces were about on a par with a sneeze at the surface. The designers were expecting a much softer surface with the engine bell possibly hitting the surface. (Hence the separate ascent stage).

Great explanation Amy! There was also another explanation for the astronauts shutting down the engine just before landing. Grumman engineers were worried that the "backpressure" of the engine exhaust might cause trouble when the LM finally landed; being the engine bell was only 12 to 18 inches above the surface. Thus, it was hammered in their simulations to shut down the engine IMMEDIATELY upon the contact light being lit. The contact light was a light on the LM panel which told the astronauts that "contact" with the lunar surface was made. These probes were attached to the bottom of the LM landing gear and descended about 1 to 3 feet below them. On Apollo 12, the crew was so hair triggered to shut down the engine due to this concern that they did shut down the engine immediately upon LM contact....still about 2 feet up from the surface. The result was a "drop" that made for a bit of a hard landing!

TheCapri48 Gaming: YOU SAID: "Ok so even though they used 3000 lbs of thrust that's still pretty powerful right" == Your car weighs 4000 pounds. That's 4000 pounds of force on a tiny little surface area of 4 tires with only about 1 sq foot each of surface contact area. Yet, your car isn't leaving massive craters when you drive across dirt. Point is, people see this big number, like 3000 pounds of thrust, and think it sounds like a really big number, but it's actually not (relatively speaking). YOU SAID: "why isn't there any dust all over the moon lander can you explain that" == Um, because it got blown away. I mean, it also depends on a lot of factors. It varied from mission to mission, and we can talk about the different amounts of dust on each mission. But, somehow, I think you're not worth the effort. I mean, all of you conspiratards repeat the same scripted talking points over and over and over. You ask questions, but it seems that none of you nutbags actually want answers. 99% of the time, you're just asking questions thinking that it's some sort of "gotcha" moment or something, expecting that there won't be a valid answer. But, the plain fact is that, without an atmosphere, dust will get blown from under the lander, sure, but it's not going to linger around in the air, and get all over everything, like dust does on Earth. That's because THERE IS NO AIR TO LINGER IN. In a vacuum, the dust gets blown, then falls wherever it falls, and that's it.

The only two rules to their game are (1) All evidence for Apollo is fake, no matter how real it is, and (2) All evidence against Apollo is real, no matter how wrong it is. You can never get around their two rules. So, yes, when they say the photos show no dust, those are "real" photos. Then, when you show them they're wrong, those pictures are "fake." All photos that help their delusion are real. All photos that go against their delusion are fake (whether they are even aware that those photos exist, or not... their conclusions are pre-determined by the two rules).

I've got another question... how did they communicate without a delay in the radio transmission? Even light would take a round trip of 2 or 3 seconds.... there's no delay at all. Talking on tv via satellite -continent to continent, theres a lag. I'm not being negative, just wondered that's all.

The thing is, it's a matter of where it was recorded from. Point being, if you're recording the conversation from the perspective of Houston, and take a specific clip, yeah, you would hear the astronauts talk from the moon, and then you hear the CapCom in Houston answer with a "normal" conversation delay (almost no delay at all). But, that very same conversation, if recorded from the headsets of the astronauts on the moon, DO have those delays. It depends on who was speaking first in whatever clip you're listening to, and which side the recording came from. The delays ARE there. Now, to caveat this, there were many shows back in the 1960s and 1970s that edited these conversations down. Every second counts on TV time, especially back in those days, and they weren't going to air some tapes with 2.5 second delays on every other thing spoken, so they clipped the delays out before airing them. Moon conspiratards often take those edited clips, and then parade them around as "proof" that the landings didn't happen. But, the original tapes have the delays, as well as SOME of the original TV broadcasts (the ones that didn't edit the clips down). Moon hoaxers also point out one or two times that an astronaut spoke very quickly without a delay (during a time when you'd expect one). But, it only happened a couple of times, and is very easily explained by the fact that sometimes, an astronaut is going to start speaking at almost the same time as CapCom is speaking. It happens in everyone's daily life also, when sometimes one person talks at the same time as another. But, with a 2.5 second round trip delay, talking at the same time ends up sounding like someone says something with no delay. It only happened once or twice, but moon hoaxers eat it up like candy, somehow incredulous to the concept that maybe an astronaut might speak at the same time as CapCom.

@@JohnSmith-yn3eb YOU SAID: "so we shouldn't go back?" == I did not say that. I said (in a nutshell) that there's no reason to go there and take HD photos of the equipment left behind. If/when people return to the moon, taking photos of old equipment should be a very very very very very low priority. YOU SAID: "I'm not saying we didn't go but Of the 5700 photos released by NASA many had discrepancies and some were blatant lies like the Michael Collins "spacewalk" photo." == First of all, the 5700 photos didn't include any spacewalks. There were 5700 photos taken from the lunar surface (nobody calls those a "spacewalk," even though technically they were in space). If you include photos taken from orbit/transit, there were far more than 5700. I have forgotten the total, but it's over 10,000. == Secondly, I know of no Apollo photograph showing Collins doing an EVA. Collins did two EVAs during Gemini. But, he didn't do any EVAs during his Apollo 11 flight. YOU SAID: "A training photo that NASA edited and passed off as real. This is a fact." == No, it is not. If you think otherwise, give me the Apollo photograph catalog number. YOU SAID: "There is no harm in revisiting the moon w.todays technology. Yes it would be cheaper & safer." == Again, probably a bit cheaper. But, not by as much as you'd think. As for safer, how in the world can you even know? No equipment has yet to even be designed, beyond the Orion command module. How can you comment on the safety of craft that isn't even designed yet? YOU SAID: "The cell phone I'm using right now has one million times the memory and seven million times more ROM than the Apollo guidance computer." == So what? Your cell phone is going to make it cheaper or safer? How? Why? What relevance is your cell phone's memory to the safety and cost of a new moonshot program? What ARE you talking about??? YOU SAID: "So yes let's go back in Ultra High Definition." == Sure, but to go there for the purpose of taking photographs of the old equipment on the moon?? What's the point? You never answered my question. Why do you want new photos of the Apollo equipment on the moon? What possible purpose does that serve? You spew a lot of ignorance around, saying completely meaningless and irrelevant things, but cannot bring yourself to answer a simple question.

without an atmosphere there isnt anything to block the blast, the blast can only spread out when you have an atmosphere to redirect the gass, without an atmosphere the blast has no friction with other gasses so it cant spread out magically by interacting with the vaccuum of space. the only thing that the blast is interacting is with the surface, which the blast should have blasted a crator into the moon and sunk in it.

Lunar landers cameras did show dust being sprayed from beneath the module as it was touching down and the call "contact light" meant that a rod on its feet was on the surface so the engine could be throttled down even more. The lack of a blast crater in the dust was because the descent engine's thrust had already blown away much of what was loose and helicopters have the same effect as they land.
