The first step on the moon by astronaut Neil Armstrong was said to be “one small step for man, one giant leap for mankind.” But for many of the twelve men who’ve been there, that “one small step” completely changed the way they saw the world. Some returned feeling as if they’d experienced enlightenment. Others spent the years following their lunar exploration depressed and hiding from the press. Some say that those quiet astronauts saw things the others hadn’t – secret things that they were asked to cover up.
