It's called evidence dickhead. You're simply too stupid to understand that if four different sources showing the same live event are all obviously different and fake, the event itself is a fiction.

You know as well as I do that years ago the argument was "where are any new pictures of the moon, why can't NASA point a telescope at the landing sites and show them to us?" Now that they have done that using LRO, you guys are moving the goalpost to "anyone but NASA." How about you first prove the LRO images are fake? Furthermore, if and when a non-NASA entity acquires images of the landing sites, what will your excuse be?

It won't happen this year, but eventually it's likely to happen. You might feel "secure" in your new goal post position for now, but there was a time when you felt secure by having a goal post that asked for new pictures from NASA. Now you openly admit you'll automatically ignore any evidence for NASA no matter what it is. If and when another entity launches a probe which gets new images of the landing sites, what will stop you from declaring them to be part of the conspiracy?

The age of private moon missions is close at hand. Yet I have no doubt whatsoever that if SpaceIL, for example, were to eventually land a probe close enough to an Apollo site to take pictures of it, you guys would bitch that "they're j00s, so of course they're lying!"

For NASA's part, their suggested guidelines for future private moon missions is that you just leave the historic first and last missions' landing sites completely alone. For the other landing sites there are no visitation bans as long as you leave the equipment alone. Their recommendations just ask that you keep your rovers 3 meters away from the descent stage and 1 meter away from other equipment at Apollo 12, 14, 15, and 16, and to drive slow when going by the retroreflectors so that you don't kick dust on them by accident since they're still used today.

Doesn't seem like they're particularly worried about anyone finding out some big secret of us "not ever having been there..."

I don't want to derail this thread (thanks for posting the video, OP, it was fascinating), but here's a good article about the moon landing hoax:

I'm guessing a shill will tell you the article is bullshit, but just read it and decide for yourself. I know where I stand on the matter of the "moon landings".
 Quoting: Anonymous Coward 32623728


That you think that article is good tells me just how ignorant you are of Apollo and spaceflight in general.

Just a couple quick points, at one point he claims that the spacesuits could not have dealt with the temperature extremes on the moon. The spacesuits today use the same basic systems and principles for thermal regulation, and have to deal with temperature extremes just as wide on the exterior of ISS for up to about 6~8 hours at a time. They still use a combination of insulation, high reflectivity, and water ice porous plate sublimators to keep the astronauts at a safe temperature. Space is a better vacuum than anything we can achieve in a lab on earth, and as such it acts as an insulator as well. There is no thermal conduction by convection in space, only by direct contact and irradiation. The spacesuits are well insulated and their porous plate sublimators also carry away excess heat via evaporative cooling (though in space it's really sublimative cooling). By claiming the spacesuits are evidence of a hoax, he is effectively claiming that they're evidence ISS is a hoax as well.

He also flat-out lies in some places. For instance, he claims that the space shuttles had just as much fuel as a Saturn V. Bullshit. The Saturn V had twice as much fuel as a space shuttle, and the mass that returned to earth (which plays into the payload fraction) was much lower than that of a space shuttle. A common saying in orbital mechanics is that low earth orbit is "halfway to anywhere." This saying refers to the fact that once you reach low earth orbit, you have spent about half the delta-V required to reach escape velocity. The Saturn V had enough fuel to boost them to the moon and they had more than enough fuel to get back.

Another lie occurs here where he uses this image to suggest that you should be able to see stars in the images alongside the sun:

What he doesn't tell you is that this is a composite image. You cannot properly expose the sun, the solar corona, and the stars all at the same time.

The Saturn V rocket used 96% of its fuel in the 1st 10 minutes.

Final altitude: 118 miles.
 Quoting: Anonymous Coward 38739120


Do you know what the Tsiolkovsky rocket equation is? Let's do a real simple calculation with it. The fully fueled Saturn V (with CSM and test mass in the case of Apollo 8) had a mass of about 2940159 kg. The S-IVB stage that would send them to the moon from orbit had a mass of about 120800 kg. The CSM had a mass of about 30332 kg. Let's just keep this really simple for now and do this calculation for Apollo 8, in which case the S-IVB weighed a further 9027 kg in dry mass (already factored into the above total S-V mass). Now the first stage fuel mass was 2169000 kg and had an Isp of about 304.8s, so the total mass minus the fuel mass is the m1 at first stage cutoff. That gets us a delta V of 3997.63 m/s. The second stage had a fuel mass of about 444000kg. Our previous m1-dry mass of first stage(131000) becomes m0 and m0-444000 becomes m1. The J2 engines had an Isp of about 426s. That gives us a stage 2 delta V of about 4937.92 m/s. Third stage, the S-IVB, also had a J2 and had a fuel mass of about 110800kg. Same as before, our m1-dry mass of second stage(36000) becomes m0, m1 is m0-110800. That gives us a 3rd stage delta V of about 4913.94 m/s. The third stage was burned twice, once to complete the parking orbit, and once to send the stack to the moon on TLI. The delta-V we just calculated for the Saturn V up to that point of the mission is 13,849.49 m/s. Traditionally, to go from earth's surface to lunar orbit requires approximately 12,700 m/s delta V ( [link to www.strout.net] ) so as you can see, they had more than enough fuel to send the CSM to the moon. The service module engine on the CSM had an isp of about 314 s and the SPS engine had 18410 kg of fuel. Given a previously mentioned CSM total mass of 30332 kg, the total delta-V for the CSM would have been about 2873.54 m/s. They didn't go back to earth orbit, however, they used that delta-V to put them on a direct re-entry course. Total escape velocity from the moon's surface is only about 2400 m/s, and from lunar orbit it only takes about 1000~1200 m/s to reach a direct reentry trajectory.

So yes, they had more than enough fuel to go to the moon and back.

A simple "X" made from black foil large enough to be seen trough a amateur telescope?

Maybe somebody can calculate exactly how large this "X" would need to be to be seen trough a amateur telescope?
 Quoting: Anonymous Coward 18171524


Speaking for my own scope, the limit of an 8" telescope's resolution is about half an arcsecond at best (actually 0.57" by Dawes' limit), only achieved with tons of image stacking on the very best nights. At that resolution, given an average moon distance of 384,400 km, that corresponds to a spot on the moon of about 1 km in width. An X 1 km wide in size would at best look like a barely perceptible slightly darker pixel when imaging the moon at the very limits of my telescope's capabilities. You wouldn't even be able to tell it was a letter. And my scope is far more powerful than anything you'll find in your local store.

To readily perceive the actual X in a scope like mine, the stripe "width" for the X itself would need to be at least as wide as the limit of the telescope's resolution. Again, that's about 1 km for my telescope. So the width of the strip you use to make the X, not the length, the width would have to be one kilometer. The length would have to be on the order of 4 or 5 km to make a recognizable X, and you'd have to do the whole operation twice, once for each strip. Sorry, but that's not fitting in an Apollo lunar lander. Figure that in total you need 8 square km of black foil to do the job. Let's say you use the lightest, thinnest kapton you can find, the same material that will be used for the delicate James Webb sun shield, and you find a really clever way to fold the whole thing up into a volume less than the James Webb without tearing it.

[link to www.dupont.com]

The above PDF lists the minimum density for really thin Kapton (12.7 micrometer!) at 14 grams per square meter. Let's say you coat this film black without adding any weight to it. You still need a whopping 112,000 kilograms of the stuff to do the job on 8 square km worth of lunar terrain! That's almost 7 times the ENTIRE MASS of the UPGRADED lunar module from the J missions, including the rover it brought with it! That's right, it's more mass than was left on the surface of the moon by all the Apollo lunar landers COMBINED. It's over TWICE the maximum payload mass an ENTIRE SATURN V MOON ROCKET could even put onto a trans-lunar insertion trajectory!

In short, no, it's not reasonable to expect NASA to blanket the moon with anything large enough to be seen by amateur astronomers.

 Quoting: Davos


The big problem with the Apollo spacesuits was how hot it got on the Moon. People think about the coldness of space or the vacuum or radiation being problems for the spacesuit, they were but the most insurmountable one was the heat on the Moon.

The Apollo astronauts would have been on the lunar surface that can reach 125 C under a blazing Sun at 6000 C. They had a primitive air-conditioner unit but the problem was there was nowhere cold for unit to dump its heat. Everywhere you looked was hot, to the Sun in the sky or the hot surface. The heat would have built up and up in the suit until very quickly the astronaut would have succumbed to a horrible heat death, nasty way to go.

The fully fueled Saturn V (with CSM and test mass in the case of Apollo 8) had a mass of about 2940159 kg. The S-IVB stage that would send them to the moon from orbit had a mass of about 120800 kg. The CSM had a mass of about 30332 kg. Let's just keep this really simple for now and do this calculation for Apollo 8, in which case the S-IVB weighed a further 9027 kg in dry mass (already factored into the above total S-V mass). Now the first stage fuel mass was 2169000 kg and had an Isp of about 304.8s, so the total mass minus the fuel mass is the m1 at first stage cutoff. That gets us a delta V of 3997.63 m/s. The second stage had a fuel mass of about 444000kg. Our previous m1-dry mass of first stage(131000) becomes m0 and m0-444000 becomes m1. The J2 engines had an Isp of about 426s. That gives us a stage 2 delta V of about 4937.92 m/s. Third stage, the S-IVB, also had a J2 and had a fuel mass of about 110800kg. Same as before, our m1-dry mass of second stage(36000) becomes m0, m1 is m0-110800. That gives us a 3rd stage delta V of about 4913.94 m/s. The third stage was burned twice, once to complete the parking orbit, and once to send the stack to the moon on TLI. The delta-V we just calculated for the Saturn V up to that point of the mission is 13,849.49 m/s. Traditionally, to go from earth's surface to lunar orbit requires approximately 12,700 m/s delta V ( [link to www.strout.net] ) so as you can see, they had more than enough fuel to send the CSM to the moon. The service module engine on the CSM had an isp of about 314 s and the SPS engine had 18410 kg of fuel. Given a previously mentioned CSM total mass of 30332 kg, the total delta-V for the CSM would have been about 2873.54 m/s. They didn't go back to earth orbit, however, they used that delta-V to put them on a direct re-entry course. Total escape velocity from the moon's surface is only about 2400 m/s, and from lunar orbit it only takes about 1000~1200 m/s to reach a direct reentry trajectory.

So yes, they had more than enough fuel to go to the moon and back.

 Quoting: Davos

Of course he doesn't SAY that, he knew it would make him look crazy (though these days that wouldn't even be crazy to most here). But it is what his claims imply; he bitches about the methods used by the suits to regulate their own temperature. Those are the same methods used to today, and on the exterior of ISS the astronauts deal with temperatures just as extreme and even more frequent cycling from day to night. If water ice sublimation doesn't work for rejecting heat during Apollo missions, then it wouldn't work today either.

In terms of weight, shuttle/ISS eva suits use fixed sized hard shell upper torsos that are designed to be interchangeable between astronauts and last for multiple missions. Since they're not designed for any surface EVAs, "weight" is not really a consideration, and they even now include small built-in thrusters to guide the astronauts back to the station should they come off structure.

Apollo suits were custom fit for each individual astronaut and only had to last for one mission. They did have to worry about weight so as to not overly impede the astronauts (and even then they weren't great for that).

 Quoting: Anonymous Coward 34745389


Nothing insurmountable about it. Their soles were extremely well insulated, as was the suit in general. The same temperature extremes are present on the exterior of ISS, thermal cycling is even more frequent (sunrise/sunset every 46 minutes or so), and the spacewalks are generally even longer.

Excess heat was, and still is, carried away by sublimative cooling using porous plate water ice sublimators and by circulating liquid in tubes around the astronauts bodies.

For a fun science experiment you can do in any high school chemistry lab, fill a vacuum flask about half way with water and place it under vacuum with a thermometer in the water. As the water boils, what happens to its temperature?

It's basically the same principle for spacesuits, only it involves sublimation rather than evaporation.

The Apollo astronauts would have been on the lunar surface that can reach 125 C under a blazing Sun at 6000 C. They had a primitive air-conditioner unit but the problem was there was nowhere cold for unit to dump its heat. Everywhere you looked was hot, to the Sun in the sky or the hot surface. The heat would have built up and up in the suit until very quickly the astronaut would have succumbed to a horrible heat death, nasty way to go.

It's a completely different environment. You have admitted that if there are astronauts on the ISS then they spend 45 minutes warming in the Sun followed by 45 minutes cooling in the shade unlike the Apollo astronauts who would have spent seven hours heating up in the Sun.

In addition they are not next to a hot radiating surface like the Moon so they can lose heat away from the Sun unlike the Apollo astronauts who would have been heated from both sides, Sun sky and Moon surface, at once with no cold side to help their air-conditioning work.

astronauts on the ISS then they spend 45 minutes warming in the Sun followed by 45 minutes cooling in the shade unlike the Apollo astronauts who would have spent seven hours heating up in the Sun.
 Quoting: AC

At least the Apollo astronauts had a constant heat load instead of a variable one. The skin of ISS is metal, with a comparatively low specific heat capacity; it heats up quickly and cools off quickly.
"Extreme non-operating temperatures for EVA in the
ISS space environment range from -157 C to 149 C while
operating temperatures range from -129 C to 121 C"
[link to citeseerx.ist.psu.edu]

The extremes are just as bad as on the moon, but it's more difficult to deal with since the load isn't even constant; you can't just find a rate at which to dump excess heat and keep a suitable temperature. I've heard astronauts speak about the problem of losing too much heat when they go into the night side of earth on spacewalk; their extremities start to get cold. You can dump more heat if you need to, but once you've dumped too much heat you have to rely mostly on body heat and insulation to warm back up until the sun comes up again.

You also have to keep in mind, but I know you won't, that there's no transfer of heat by convection in space, even on the moon. The moon's surface temperature can only transfer to the suit by direct contact (for which they are extremely well insulated) and by reflected or radiated light. It's not like an oven on earth. The same goes for working on and around ISS as well, of course.

Yes that's exactly my point. If there was an ISS spacewalk the astronaut would be heated and cooled in equal periods during a 90 minute cycle. The average temperature would be like a nice European spring day.

On the Moon its like a furnace. The hot surface is radiating heat at the astronaut at the same time the Sun is scorching him from above. It would be unrelenting for 7 hours or more and there is no cold sink for the air-conditioner to exhaust its heat to, curtains for the Moonwalker.

A simple "X" made from black foil large enough to be seen trough a amateur telescope?

Maybe somebody can calculate exactly how large this "X" would need to be to be seen trough a amateur telescope?
 Quoting: Anonymous Coward 18171524


Speaking for my own scope, the limit of an 8" telescope's resolution is about half an arcsecond at best (actually 0.57" by Dawes' limit), only achieved with tons of image stacking on the very best nights. At that resolution, given an average moon distance of 384,400 km, that corresponds to a spot on the moon of about 1 km in width. An X 1 km wide in size would at best look like a barely perceptible slightly darker pixel when imaging the moon at the very limits of my telescope's capabilities. You wouldn't even be able to tell it was a letter. And my scope is far more powerful than anything you'll find in your local store.

To readily perceive the actual X in a scope like mine, the stripe "width" for the X itself would need to be at least as wide as the limit of the telescope's resolution. Again, that's about 1 km for my telescope. So the width of the strip you use to make the X, not the length, the width would have to be one kilometer. The length would have to be on the order of 4 or 5 km to make a recognizable X, and you'd have to do the whole operation twice, once for each strip. Sorry, but that's not fitting in an Apollo lunar lander. Figure that in total you need 8 square km of black foil to do the job. Let's say you use the lightest, thinnest kapton you can find, the same material that will be used for the delicate James Webb sun shield, and you find a really clever way to fold the whole thing up into a volume less than the James Webb without tearing it.

[link to www.dupont.com]

The above PDF lists the minimum density for really thin Kapton (12.7 micrometer!) at 14 grams per square meter. Let's say you coat this film black without adding any weight to it. You still need a whopping 112,000 kilograms of the stuff to do the job on 8 square km worth of lunar terrain! That's almost 7 times the ENTIRE MASS of the UPGRADED lunar module from the J missions, including the rover it brought with it! That's right, it's more mass than was left on the surface of the moon by all the Apollo lunar landers COMBINED. It's over TWICE the maximum payload mass an ENTIRE SATURN V MOON ROCKET could even put onto a trans-lunar insertion trajectory!

In short, no, it's not reasonable to expect NASA to blanket the moon with anything large enough to be seen by amateur astronomers.

How many times do I have to tell you before you get it? They didn't need to go into a shadow to "cool off."[citation needed] Their spacesuits actively dumped heat by sublimation. But guess what? The sun's only striking one side of the spacesuit at any given time...
 Quoting: Dr. Astro

On the ISS. Which is what would make the heat load much more manageable there, the average over 90 minutes like a pleasant spring morning in northern France. On the Moon the Sun is heating one half of the astronaut while at the same time the entire hot surface around him is radiating heat towards him from every direction, 360 degrees around. You don't have that on the ISS.

It is completely different. You don't understand. An astronaut on the ISS would be heated by the Sun only, for 45 minutes before cooling again for 45 minutes. An astronaut on the Moon would be heated by the Sun and the hot Moon surface simultaneously and without cooling off, for 7 hours or more. What part of this do you not understand?
 Quoting: Idiot

And the temperature extremes are just as bad, only more frequent. It still has to dump excess heat in the sunlight, which it does, and it has to retain heat in the dark, which it does (though a little less well by the sound of it). Dumping excess heat is NOT A PROBLEM.[citation needed]
 Quoting: Dr. Astro

Do you think, just for once, you can discuss a matter with someone without resorting to petty insults and losing you temper?

The temperature extremes would not be as bad on the ISS for two important reasons.

1 there is a 90 minute heating and cooling cycle that limits the extremes of high and low temperature and averages out to a very manageable temperature.

2 The Sun is the only source of heat for notional ISSnauts, unlike on the Moon where the entire hot surface is radiating heat towards the astronaut, doubling the heat load and offering no cold sink for cooling systems.

The average of being in sunlight or shadow on the moon would be no different.

Are you having a laugh? "Neil, this is Houston, we notice you have been in the Sun for 30 minutes now so we would like you to find a fuck off big boulder to crouch behind for half an hour so you can cool down again"

 Quoting: Anonymous Coward 34745389

You have the hot surface of ISS conducting heat directly to the astronaut and reflecting far more light per unit surface area, to say nothing of the bright earth below.

Let me stick you in an over for 45 minutes and then a freezer for 45 and see if you think it's pleasant. Yes, managing heat loads is more difficult given the constant cycling.

I dont think he says modern spacesuits are fake, he just brings up the fact that the apollo suits were roughly half the weight of a modern space suit.

Which is odd given the improvements to materials in the 50 years since.
 Quoting: Davos


The big problem with the Apollo spacesuits was how hot it got on the Moon. People think about the coldness of space or the vacuum or radiation being problems for the spacesuit, they were but the most insurmountable one was the heat on the Moon. 
 Quoting: Anonymous Coward 34745389


Nothing insurmountable about it. Their soles were extremely well insulated, as was the suit in general. The same temperature extremes are present on the exterior of ISS, thermal cycling is even more frequent (sunrise/sunset every 46 minutes or so), and the spacewalks are generally even longer.

Excess heat was, and still is, carried away by sublimative cooling using porous plate water ice sublimators and by circulating liquid in tubes around the astronauts bodies.

For a fun science experiment you can do in any high school chemistry lab, fill a vacuum flask about half way with water and place it under vacuum with a thermometer in the water. As the water boils, what happens to its temperature?

It's basically the same principle for spacesuits, only it involves sublimation rather than evaporation.

 Quoting: Dr. Astro


Conduction would not be the problem for ISSnauts as the contact area would be very small and transient. The station surface varies between a modest 40 C and a chilly -12 C, very manageable for any space walker and like I said an average of a pleasant spring morning in Normandy. [link to www.dailymail.co.uk] The Earth itself radiates at an average temperature of 15 C, altogether quite a benign environment compared to the hellish 125 C of the Moon surface!
