It is scientifically and physically impossible for man to set foot on the Moon. The fact that we need a constant intake of water means that man could not go to, let alone step foot on the Moon or even Mars. Despite what NASA will have you believe, one giant leap of faith, we cannot live on Mars even if water exists. We need massive amounts of atmospheric water vapor to inhale and a precise amount of atmospheric water pressure to surround us to survive. Man was in 1969 and is today in 2012 technologically confined to Earth.
