We've never been there!
An astrophysicist who has worked for NASA writes that it takes two meters of shielding to protect against medium solar flares and that heavy ones give out tens of thousands of rem in a few hours.
Russian scientists calculated in 1959 that astronauts needed a shield of 4 feet of lead to protect them on the Moons surface. Why didn't the astronauts on Apollo 14 and 16 die after exposure to this immense amount of radiation? And why are NASA only starting a project now to test the lunar radiation levels and what their effects would be on the human body if they have sent 12 men there already?
Apollo missions were bollocks - even traversing the Van Allen belt (which would have taken them 4 hours) the astronauts would have received lethal doses of radiation.
Yes, yes there's always going to be conspiracy theorists - but just take a look here http://www.ufos-aliens.co.uk/cosmicapollo.html there's a few piecesbeing read into a bit much but it's interesting reading nevertheless - the gravity videos, especially of the astronaut getting up unaided from the ground is just spectacular!
