I wonder if you can trust 100% what a govement tells you, with NASA you believe everything?? even though you know it is politics.I ask you to look back 2,10,50,100,1000year and see if what was said is what was now we know better.How many examples could your find 50% of history? 30%?? 10??I think you would struggle to find more than 5% was as it was stated to be at the time.I ask this how mush mony did Kennedy put in the Moon prodject? I think it was pissed off politics
