Is there sufficient evidence to support the theory that astronauts never landed on the moon?

Yuri Mukhin – Russian opposition politician, publicist and writer of the book The Moon Affair of the USA (2006) in which he denies all Moon landing evidence and accuses the US government of plundering the money paid by the American taxpayers for the Moon program. He also claims the Central Committee of the Communist Party of the Soviet Union and some Soviet scientists helped NASA fake the landings. Alexander Popov – Russian doctor of physical-mathematical sciences and writer of the book Americans on the Moon – A Great Breakthrough or a Space Affair?

(Moscow, 2009, ISBN 978-5-9533-3315-3) in which he aims to prove that Saturn V was in fact a camouflaged Saturn 1B50 and denies all Moon landing evidence. Stanislav Pokrovsky – Russian candidate of technical sciences and General Director of a scientific-manufacturing enterprise Project-D-MSK who calculated that the real speed of the Saturn V rocket at S-IC staging time was only half of what was declared. His analysis appears to assume that the solid rocket plumes from the fuselage and retro rockets on the two stages came to an instant halt in the surrounding air so they can be used to estimate the velocity of the rocket.

He ignored high altitude winds and the altitude at staging, 67 km, where air is about 1/10,000 as dense as at sea level, and claimed that only a loop around the Moon was possible, not a manned landing on the Moon with return to Earth. He also allegedly found the reason for this – problems with the Inconel superalloy used in the F-1 engine. Philippe Lheureux – French writer of Moon Landings: Did NASA Lie?

And Lights on the Moon: Did NASA Lie? (Lumières sur la Lune: La NASA a-t-elle menti?). He said that astronauts did land on the Moon but to stop other states from benefiting from scientific information in the real photos, NASA published fake images.

Many conspiracy theories have been put forward. They either claim that the landings did not happen and that NASA employees (and sometimes others) have lied; or that the landings did happen but not in the way that has been told.
