More and more people are questioning Nasa's credibility; and with good reason...Russia was beating the US in EVERY aspect of Space; until Nasa "put men on the moon" & returned them safely; multiple times nearly 50 years ago!..NOT A SINGLE Human, from ANY NATION has left Low Earth Orbit since 1972!..Given technological advancement over the last 50 years; inquiring minds are justified in their skepticism of the lunar landings & thus Nasa in general...Is it more reasonable to consider that the US Gov't faked the Apollo landings to win the space race; or that ALL of humanity decided that there was nothing worthy of further Manned exploration beyond Low Earth Orbit?
