During Apollo 11, while the astronauts were on the moon's surface, the Lunar Command Module was orbiting above the moon at 3,600 miles per hour. To put this into perspective, a typical .223 rifle round fired from a 16 inch barrel travels around 2,000mph. After 21 hours of moonwalking, Buzz and Neil launched from the lunar landing module to meet up with the orbiting command module in order to travel back to earth.

Essentially, you have a giant hunk of metal traveling 1.5 times faster than a rifle round and you launch another hunk of metal to meet up with it. The math is insane. I cannot find any details on the internet that go into detail how the landing module rendezvous with the command module.

Here's a chart of seconds elapsed for each of the major mechanical events of the Apollo missions, allowing comparison of all of them. What you're looking at is number of seconds that each configuration was in flight. The various stages (and configurations) of the rocket are in flight for a few minutes at the start, then other configurations run for several minutes, or hours dependinging on which one you're looking at.

Throughout the Apollo program, Apollo 11 had the shortest LM flight time from the time of undocking until lunar touchdown. They were all business and their main focus was to simply stick their landing, get it done and go home. However, Apollo 11 also had the LONGEST flight time from the surface of the Moon BACK to the CSM hurtling through lunar orbit , at 13260 seconds (you do the conversion). Apollo 14 was like half that for that phase of their mission.

Just listen to these retarded answers yet once again - it's like someone being mad over being forced to explain something, which is lacks in any kind of detail whatsoever. Theoretical calculations aren't proof of anything. I can postulate the space carrier to hold just whatever weight I want it to be and resonate the theoretical energy needed for, let's say a takeoff, and then postulate the vessel carried exactly this much weight of a given fuel type.

Inquiring about docking or a liftoff supposedly being capable of taking off from a bare moon surface, a feat that takes tremendous effort and work from the earth not to mention infrastructure being built, is just answered with "m-muh thrusters and radars!".

Just look at >>15984897 - it's nothing but one long blabbering of assumptions and not cutting to the deal. Anyone in academia knows, if someone isn't able to explain something in layman's terms they don't understand it.

The curiosity rover had a weight of 900kg according to NASA themselves: https://mars.nasa.gov/msl/spacecraft/rover/summary/

Now are we seriously supposed to believe an ascent module made for taking off, landing, lifting off, bringing all instruments and two pilots and keeping them alive for days weighing a mere 2500kg? It supposedly also carried a fucking vehicle, the lunar rover.

How did the docking happen? An extremely delicate process is simply explained with "thrusters and radars".

Spot on - you're even saying it yourself now. I didn't ask for a "specific part list", but rather a categorical breakdown of the different general components and their weight such as the supposed "lunar rover", weight of the astronauts, hull. These things aren't super specific - shouldn't it be easy for NASA to post such information?

There isn't. Everything is based around countless of assumptions, logical or illogical, and the whole thing becomes an informational mush very far from actual applied science.

This isn't some flat earth fringe stupid conspiracy theory post. There is no conspiracy regarding the supposed moon landing events. They simply didn't happen.

>Are there are things that you question the legitimacy of?
Naturally so, the whole thing. Specifically the lack of information and lack of actual scientific methodology when inquiring about details. Detailed explanations are scolded off with "thrusters and radars" and module weights were supposedly much less than modern amateur submarine vessels also supposedly able to withstand liftoff, takeoff and docking. Lack of details regarding the docking mechanism. Or comparing the weight with modern day rovers and vessels seeing the module supposedly weighed approximately only two to three times of the curiosity rover while carrying a lunar rover capable of manned driving and being able to sustain astronauts for three days. Then you have the whole political aspect of it - all the supposed landings happening under one presidential term at the height of the cold war in the backwater of the failed Vietnam War, never having gone back and the stupid "explanations" provided for it ("m-muh it's expensive!") despite millions of times the computing power and advancement in practically all technology sectors.

The Titan submarine was made, looking past the fact it was even amateurish by design, for a couple of hours of deep sea exploration. The ascent module was supposedly made for travelling in space, landing on a bare surface and taking off from it again along with brining a vehicle and designed to keep astronauts alive for three days. All with 60s and 70s tech. The ascent module supposedly weighed 1/4th of Titan.

>i really dont see why this is hard to grasp
I find it extremely hard to believe how the ascent module supposedly could adjust itself to match the orbit of the command module, get close enough without colliding, then manually being steered by thrusters and radars to supposedly dock the module. We're talking about speeds of 1600 m/s - how much thruster force is needed to steer and match the orbit of the command module of a vessel? When was the manual steering done?

not sure what part is implausible here. the relative speeds become smaller as you match the speed of the docking object, and once its relatively still to you, you can slowly maneuver whether by automatic or manual means. the absence of outside forces such as drag makes this even easier compared to say doing the same maneuver between two boats at full speed

You will never be convinced because ultimately short of putting you on a rocket to the moon nothing will convince you. Even if we convince you that it was technically possible you will claim there is no way they'd risk it and everything was faked.
The most solid evidence that they really went is how high the dust goes for how slow the wheels are spinning in the rover. If that doesn't convince you nothing will.

I couldn't tell you, but definitely more than a modern day vessel made for deep sea exploration for a couple of hours. The ascent module supposedly weighed 1/4th the weight of Titan being supposedly designed with tech decades older with multiple functionalities such as landing, taking off, bringing a "lunar rover" and keeping astronauts alive for multiple days. Comparing with modern day space crafts and vessels the weight of both the ascent module and command module are just laughable.

It shouldn't be easier. You're manually navigating three dimensional space, whereas boats can't move vertically. Also the higher velocity makes for a smaller margin of error since just the simplest of mistakes have grave consequences.

Let alone the fact that titan resisted pressures of hundreds of atmospheres while apollo resisted only 1 atmosphere.
A small hole in the hull of Apollo wouldn't necessarily be catastrophic. The ISS had a hole and it was patched up.
Plus you haven't researched how thick is the hull of modern spacecraft. Why not begin there?
Have you ever seen radio vaccum tubes? Those are made of very thin glass and they have to resist the same pressure differential that a spacecraft does.

this is a really bad example, its a vehicle designed to withstand 400 times the pressure, and travel in a different medium. And how would our modern tech change this, exactly? I suppose the material of the Titan is a bit more modern, but if we compare that to 60s tech, the weight difference should be even greater, which doesnt exactly help your argument

so what would the difference in weight be between a sub built to withstand 2 atmospheres and 400? does the amount of pressure not change how thick your hull must be? do you now see why its not unfeasible to think that a submarine would be heavier than a spacecraft?

It's not just about withstanding pressure like I also pointed out - it's also about designing around hull integrity. In deep sea you don't have the risk of space rocks colliding with the hull at high velocities. You're focusing only on one aspect, where I have pointed several out. What about the weight of an added lunar rover? The ability to deploy it? The capability to land and takeoff? It's the summarized weight of these additional things too.

Naturally the hull must be optimized to the pressure, but that's not the only factor at play here, like I have pointed out several times.

No I really don't to be honest. The curiosity rover by itself weighed 900kg, around 1/3rd of the the ascent module with extremely limited capabilities compared to the ascent module. The lunar rover supposedly weighed 210kg, less than 1/4th of the Curiosity rover. Can't you see these things don't add up?

The gravitational force pushing down on the object doesn't matter - comparison of weight is just a ratio.

Curiosity: 3 : 2.7 : 2.2 (LxWxH)
Rover: 3.1 : 2.3 : 1.1 (LxWxH)

So they are dimensioned roughly the same with the curiosity being around a meter higher/taller than the rover. Yet the rover is less than 1/4th the weight along with supposedly having a payload of 490kg. That's more than a Toyota Aygo weighing roughly the same as the Curiosity.

There's something extremely off with the numbers and something doesn't add up. Now these are just for the vehicles - add in all the other things.

without having read any other post, you are thinking about space vehicles in terms of earth mechanics. we can construct vehicles and structures for space to be far lighter than would be needed for earth because there is no atmospheric pressure to speak of.
the heavier something is, the stronger its structure needs to be to accelerate it. spacecraft only need walls sturdy enough to keep any relevant atmosphere contained and to survive whatever acceleration they need to go through.

Post the fucking specs. Are you retarded? The gas powered version has the highest ratio being 680.3kg / 450.4kg = 1.5 (or 150%). This is also based on the curb weight, which doesn't include passengers and if a grown adult man of lets say 80kg drove the vehicle the payload ratio would be a little less than 1.3. These numbers perfectly are within the margins of the previous numbers for construction site vehicles shown here: >>15989067

agreed, that aligns with what i said, though it would be "mass" not weight. Acceleration is what makes weight, and you need to accelerate to take off from the surface of the moon.
the moon's gravity exerts acceleration on you that makes you experience 1/6th weight. when you go to take off from the moon you must accelerate away from it and overcome that gravitational acceleration, which means you would, for a time, experience a greater weight.
notice that ratios never came into play, it is a question of whether the material something is made of can withstand the force being applied to it (which is an absolute value, not something that changes with location).

to accelerate an object by a certain amount you need to apply a certain force proportional to its total mass. this is elementary school physics. we know the weight of the vehicle in this case, which means the force, too, is a knowable number.
when constructing a space vehicle, you would presumably be given design constraints like "this needs to be able to achieve X acceleration without falling apart". materials are then selected to minimize mass while meeting that goal.

The max payload is the downward force that the wheels and suspension can carry without potentially bottoming out and or breaking and damaging the vehicle. On the moon that downward force is 1/6 what it would be on earth so the suspension and tires of a given vehicle would be much less compressed with the same mass payload on the moon vs on earth. To compress the springs and put force on the vehicle equal to earth you would need 6x the mass. The springs and the frame do not get 6x weaker on the moon.

You can't linearly determine, simply from the gravitational force, that the mass needed to be applied would indeed be 6x higher to produce the same amount of strain on the design - motor mechanics would also be affected. You're basically saying a human weighing 1/6th of the weight he would do on earth would also be able to carry 6x more weight than he would be able to on earth simply due to the gravitational force exerted on him being less. His whole body, joints and the likes, would function differently.

Nevertheless, we're comparing payloads listed from specifications on earth, which are 210kg for the "lunar rover" and a payload of 440kg making the ratio, like I have already said multiple times, 2.1.

See now you are mixing mass and weight. He would be able to carry 6x the mass which would be the same weight(downward force) he could carry on earth. You don't get stronger on the moon but things have less downward force so things you couldn't lift on earth with earth gravity could easily be lifted on the moon with moon gravity.

Let's see what NASA actually writes here:
https://nssdc.gsfc.nasa.gov/planetary/lunar/apollo_lrv.html

>The Lunar Roving Vehicle had a mass of 210 kg and was designed to hold a payload of an additional 490 kg on the lunar surface

NASA doesn't even clarify whether the given weight is "lunar weight", as they call it, but only clarify the payload is 490kg on the moon's surface. This is the official nasa.gov site.

Now let's assume the given weight is on the weight or mass on earth. On the moon the "lunar rover" would weigh 1/6th of the weight it would have on earth, which would be 35kg. Therefore, the proposed payload would be 490/35 = 14 (or 1400%).

Assuming the weight of 210kg is on the moon's surface we would get a payload ratio of 490/210 = 2.33, even higher than the first estimate I found elsewhere.

Now tell me what you're actually arguing for here with NASA's official numbers given? Why do other vehicles having the same payload not exist? Don't you find NASA's official data and site suspiciously amateurish? It can't be that hard for a governmental institution to use correct terminology and documentation for supposedly one of man's greatest achievements.

Lets abstract this for a moment. An astronaut wants to work out on the moon. His normal earth routine includes a static heavy hold of 225 lbs this means he is holding the bar stationary above his chest not moving/accelerating the bar. How many more 45lb plates would he need to bring to the moon to get the same workout in moon gravity. Ignore the weight of his arms because they aren't an appreciable fraction of the 225 lbs and he is lying on a bench with a symmetrically loaded bar so there are no balance issues.

They say mass so I'm going to assume mass for both numbers.

210+490kg=700kg
On the moon so gravity is 1.62m/s^2
Total max downward force on the moon is 700x1.62 = 1134N or 1.134kN

The max force is the same wherever so on earth it is still 1134N
So divide by earth gravity 9.8m/s^2
1134/9.8=116kg
Which is less than the mass of the rover itself which means the moon rover wouldn't be able to drive on earth.

now do my math problem.

How big space is is irrelevant. You can replicate the conditions in a room sized vacuum chamber. The pressure differential at Titan's max depth is objectively 400 times stronger than the differential in space. And you talk about "hull integrity". What do you mean by that exactly? Holes? Depending on how big the hole is, the depressurization wouldn't be instantaneous. Like I said, the ISS has had a hole before and nobody died.

So you calculated the collective weight plus payload capacity to be 116kg on earth. How does this make any sense at all compared to the postulated weight of 210kg from NASA? Shouldn't the numbers be proportionate to a factor six due to the difference in gravity? See how the numbers don't make any sense at all?

Your mistake is assuming payload ratio stays constant with gravity.
Gravity does affect payload ratio.

Regardless, the same logic can be applied to any spacecraft meeting up with an orbital space station. The surface of the Earth on the equator relative to space is about 1,000 mph, the International Space Station. The International Space Stations orbital velocity is 17,136 miles per hour.

The way this is acheived is simple, orbits are predictible, so you can predict where an orbital space station is going to be in a given time frame. Any margin of error can be corrected with simple station keeping mechanisms

You don't understand this isn't beyond the scope of the discussion it is the fundamental point of misunderstanding that makes you wrong here.

Mass is a fundamental property of matter since you have a Bachelors in chemistry you would know a mole of whatever element has a fixed mass which means if you have some quantity of matter the mass doesn't change on earth in space on the moon wherever.

Weight is the downward force that that mass has in a gravity field. When you put something on a scale even if the scale says grams it isn't a mass measurement device it is a force measurement device. Which is why you can fuck with a microgram scale by having a fan in the room.

The weight of an object is dependent on the gravity but the gravity on earths surface doesn't vary enough to cause problems so grocery stores can still have gram or kilo weights listed because everywhere around the world scales will show the same value.

When you go to the moon the gravity is 1/6 so you can take a mass from earth and a scale from earth and the scale will only show 1/6 what you measured on earth. This is because the scale measures force not mass.

The concept of mass versus weight isn't used at all in chemical engineering, where we usually work with simply the weight and quantity (molar).

I get the correlation between mass and weight and the difference of something having an inherent mass and the force being applied to the object. This still doesn't answer the question in relation to NASA's numbers. We're once again diverting away from the topic of discussion.

NASA proposes a weight of 210kg and they don't state whether it's "lunar weight", a stupid term, or the weight on earth. Let's assume the payload, like you say, isn't linearly scalable - the weight of the vehicle should still weigh six times more on earth than it does on the moon.

That gives the weight (or mass, I am using them interchangeably and know the difference, I am always referring to weight in kg) of the rover supposedly being 1260kg on earth. The gravitational acceleration is always based on a factor six and according to what we previously stated the payload should supposedly be six times higher (as you also wrote earlier) - so what gives NASA's numbers? This is by assumption of linear scaling, but the payload certainly can't decrease. Your calculation does not make any sense whatsoever according to what NASA is proposing

Let me put this in a way you might understand. You have a small scale that maxes out at 50g that's the max payload of the scale. So if you put 100g the scale doesn't work properly and just shows ERR instead of 100g. If you take that scale to the moon the max value of the scale is still 50g so but to get it to actually show 50g you would have to add 300g of stuff on top of the scale. So the max payload of the scale is 300g on the moon.

The proposed payload of 490kg on the moon's surface corresponding to the weight of the rover being 35kg (based on NASA's postulated weight of the rover being 210kg) adds up to a payload of 1400%.

That's 490/210 which is 233% you are just doing random math to get 1400%.

It's a similar problem to that faced by a golfer who has to pocket a golf ball in a 4-inch hole from a distance of 500 yards. The key is to incrementally reduce your error.

Why 1400% of weight ratio on the moon doesnt make sense? The materials stay as strong as they were on earth, so rover can support the same weight as on earth, which means 6 times more mass

>> No.15989935

>>15989924
This has been discussed already. The other anons propose 210kg is the weight on earth making the weight on the moon of the rover 35kg. You're actually using MY assumption in the first place getting to the payload of 230%, which is almost 100% higher than most modern vehicles in construction (being between 100-140%) or magnitudes higher than any other vehicle in existence. Again - did you even read the thread? The payload ratios don't add up no matter how you twist and turn the data furthermore not being scalable by a factor of 6.

There is no "random math" to get to 1400%. This is using the numbers proposed by the other anons. If 210kg was indeed the "lunar weight" it would need to be multiplied by 6 to get the weight on earth being 1260kg not referenced anywhere in relation to the rover's weight.

>>15989929
Even 230% is abnormally high - just try and wrap your head around the number. The car supposedly being able to carry 14 times its' weight? You can't just say "bruh, it's the material!". These payloads are extremely far off any vehicle existing out there even decades later

Why shouldn't it?

Normal cars are not being built to be as light as possible, disregarding most safety or even a crew cabin. Its litterally just frame on wheels with a battery and a seat.

On moon materials dont get weaker, so they can just support 6 times more "stuff" than on earth, because "stuff" weights less, it presses 6 times less on the springs and the frame. So why ratio shouldnt be ridiculously high on the moon? You seem to have issues with basic logical reasoning.

Because the 1400% payload would be based on a scale up of the supposed 233% payload on earth, which is almost 100% higher than what is cited in literature on payloads for construction site vehicles. A modern pickup truck has a payload of 0.27 or 27% No vehicle whatsoever everywhere anywhere has a payload capacity of 230% - it simply isn't possible.

Has a Gross Vehicle Weight Rating of 6010 lb with 1985 lb of that being payload so that leaves 4,025 as the vehicle weight.
The payload to vehicle weight ratio is 1985/4025 or 49% we love trucks don't we folks.

On the moon the GVWR is still the same because the vehicle has the same structural strength and the same springs and shocks nothing has changed except the gravity. So if you could ship a ford f150 to moon the GVWR 6010lb but because gravity is 1/6 the weight of an F150 is 4025/6= 670. so the total payload capacity of an F150 is now 6010-670= 5340.

you can buy the game kerbal space program. And then you can try landing on the moon using a lander and an orbiting command module. Then you can try rendezvous.

Turns out it's ridiculously easy.
You know where the command module is, so you just get your lander to enter the same orbit.
If the lander is ahead of the command module, you increase the radius of your orbit so that you travel a longer distance, and the command module catches up.
If you are behind, you reduce your radius so that you travel a shorter distance, so you catch up.
It's not intuitive, but it works. You can try it in the game

Instead the pilot would stand during the flight, and simply lean backwards, forwards or side-to-side to move the center of gravity relative to the center of thrust of the fixed engine. As a result, the offset thrust would cause the LESS to rotate until the astronaut returned to a neutral position and the center of gravity was again aligned with the engine thrust. Ultimately, however, this was considered to be less desirable than hardware control, particularly as it imposed significant constraints on vehicle thrust level and inertia

Thanfully ascent module was reliable enough and these ideas where never realized.

The fuel calculations were provided in the previous thread and you started to claim that Tsiolkovskys rocket equation - basis for all spaceflight is incorrect.

What buzzeords? Hyperglicolic fuel is a buzzword to you? And you claim to be a chemist?

What does satellites have to do with a multiple supposed moon landings?

Of course there was. Just look at the nice drawings!

>>15990155
No I didn't - I never claimed the rocket equation was incorrect.

>>15990156
The whole moonie subculture is filled to the brim with buzzwords, so you can easily dish something out to anyone logically being able to point out or question details regarding the "landings".
>Oh, haven't you heard about the Lunar Crapper? The astronauts would take a shit in the ascent module followed by the Lunar Crapper converting their excrements into delicious moonbaked lunar steaks!

Well they started doing satellites before the whole moon landing thing and then they kept doing them to this day so clearly you can't deny that satellites are a thing that exists and works this is a baseline so that you can't claim later that space isn't real.

Because the same things apply to both. And your assumptions also make satellites impossible.

Maybe they mean that it can carry a payload of 490kg *on the moon*.
On Earth that would be a mere 82 kilos, which would lower the payload ratio to a mere 39%.

I read both your threads, you started off claiming you were just asking questions which is "the basis of science" and 300 posts later were calling everyone moonies. I hope you were properly humiliated by this experience. I learned a ton about space travel. Godspeed OP.

It's not that we cannot you fucking retard, there are very specialized production lines that exist even today, the customer base is very small.
We aren't producing it for commercial use because it's unprofitable to create the whole production chain of every part.
Even those few factories that exist already saturate this extremely niche market.

We didn't land on the moon, it was a scam in order to 'win' the space race.
>B-but the Soviets would have called us out on it
The same Soviets who had numerous contracts with the USA for vital supplies?
They got the 'first man in space' victory, they lost nothing.
