The first moon landing is rightly seen as a heroic endeavor, packed with metric tons of glory. But there were, shall we say, less glamorous sides to the mission. One of them was the "gross flatulence" (as Collins described it) brought on by the bubble-heavy water they drank in space. Collins described the smell as "a not-so-subtle and pervasive odor which reminds me of a mixture of wet dog and marsh gas." EW, TMI, MICHAEL!
