About 450,000 Americans and 200 Germans worked on the Apollo program. The German contribution to Apollo was about 0.05%.

Every dollar spent on the space program grows the economy by $7. You're welcome.

That's a load of nonsense.

What evidence do you have to back up your claim?

You approve of having people starve in the streets?

@arclightredux6088 I just told you how many.

They were planned, then cancelled.

it's quite possible they replaced the gimbal actuators with solid rods. I think the actuators were hydraulic, you don't want to have an active hydraulic system on a museum piece.

@amyredford7158 It took 450,000 people to solve all the problems that needed to be solved to get to the Moon. There were about 200 German scientists, so they did about 0.05% of the work. von Braun made people aware of the possibility, Kennedy convinced the American political system and the public it would be a good idea, and 450,000 people advanced the state of the art from the 100 km altitude von Braun had reached to the Saturn V that would carry people to the Moon.

@arclightredux6088 no, 450,000 people in total.

There's tons of evidence that supports the moon landings being real, and no evidence that supports the idea the moon landings were fake. All of the so-called arguments the moon hoaxers come up with fall apart with even a cursory examination. Why do you believe a story that has no supporting evidence?

No.

There were several factors: the Vietnam war (which cost so much money the US had to cut spending everywhere else), general aversion to expensive projects (even in the 1960 there were people who found Apollo too expensive), and the reality of manned spaceflight (manned missions to Jupiter would have made Apollo look cheap, and Apollo/Skylab revealed there were many unsolved problems for long-duration flights).

Yep, lots of progress in a short time. That's what you get when you're handed a blank check.

@marcleblanc3602 In the 1960s, NASA's budget was about 10% of the total federal budget. The budget cuts came after Apollo 11.

@Exmarine268 The live TV broadcasts are just the start. They can't be faked - there is no place on Earth large enough to film the moon walks and rover traverses. That Saturn V launch really did send people to the Moon: amateurs and foreign countries (including enemies like the Soviet Union, who would have loved to expose the American effort as a hoax) could track the CSM on its way to the Moon. The first Surveyor missions in the early 1960s showed it's possible to land on the Moon. The Russians were able to land on the Moon, and return lunar samples. More recently, the Chinese have landed on the Moon. We can still use the laser reflectors left on the Moon by the Apollo astronauts. We have several hundred kg of lunar samples - these rocks and dust are different to anything found on Earth. Every single moon hoax argument falls apart when you examine it. Why do you believe in an idea that's so easily disproven?

Clearly you haven't done any research. The SR-71 was built to leak on the ground because it would fly at Mach 3 for several hours, which would heat up the airframe and the expanding metal would seal any leaks. The Saturn V is out of the atmosphere in a few minutes, so heat soak isn't an issue and you can build tanks that are gastight. "the power of vacuum" is a pressure difference of 1 bar. For 200 years we've been building steam engines which work a pressure vessel that works at a pressure difference 20 times higher. Hydraulic systems work at a pressure 200 times higher, and do it routinely without leaks. Building a vessel that has 1 bar inside and 0 bar outside is easy.

@fireballxl-5748 More lack of research from you. The leakage rate of the SR-71 wasn't large enough to "waste thousands of $ of fuel". The SR-71 was the first aircraft built for Mach 3, and they cut corners. Later high-speed aircraft like the MiG-25 and the B-70 didn't have leaky fuel tanks. Rockets don't have leaky fuel tanks. You again overestimate "the power of vacuum". Atmospheric pressure is 1 bar, which is 1 kg per cm2. If you have a vacuum vessel at ground level, 1 kg/cm2 is the force it has to withstand. If you have a pressure vessel with a pressure of 2 bar inside, it has to withstand that same force of 1 kg/cm2, this time from the inside. There's none of the 'negative infinity' you imagine. Five minutes with a physics textbook will confirm this.

@fireballxl-5748 Then the radiation. Again, you haven't done your research. For radiation, there are 2 important variables: 1. the radiation intensity 2. the amount of time you are exposed to this intensity. You can multiply these two and get the total radiation dose. Humans die if they receive a dose of about 300 Rad. In 1958, James van Allen and his team discovered the belts that were later named after him. He also measured the radiation intensity. This is what he found: in the part of the belt where the intensity is highest, it is high enough that if you stay for about a week, you receive a lethal dose. So for the Apollo missions, the trajectory was designed to minimize the amount of time spent there. When the Apollo astronauts flew through the van Allen belts (which took about an hour), they received a dose of radiation of between 0.16 and 1.14 rads, or less than 1% of a lethal dose. The Apollo CSM, LM and space suits had minimal radiation shielding because that's all they needed.

@fireballxl-5748 You're still overestimating the amount of force it takes for a container to hold 1 bar of pressure. Yes, a railroad tank car can implode when a vacuum is pulled inside the car. That same tank car has no problem holding a pressure of 1 bar higher than the outside pressure: most materials are much stronger in tension than in compression. Spacecraft in a vacuum are in tension. Consider this: airliners fly at an altitude of 10 km, where atmospheric pressure is 0.2 bar. The pressure in the cabin is held at 0.8 bar (to make sure the passengers don't faint from lack of oxygen). Airliners typically have an aluminium fuselage about 1 mm thick. That's all it takes to withstand a pressure difference of 0.6 bar. 2 mm thick is enough to withstand a pressure difference of 1 bar.

@chaseschneier1076 Rockets are not developed by one person. von Braun was director of MSFC, he set the high-level parameters. Thousands of scientists and engineers had input on the design.

No, that's not the truth. Over 200 missions have left Earth orbit.
