Just too bad he isn't around for this stuff, the de facto King of aerospace engineering as it relates to space exploration, easily the most important and influential popularizer of it in history and one of the greatest visionaries of all time. Got humanity both into space and then to the moon for good measure. After the Apollo program was winding down, he was ready to tackle Mars but the US Government wasn't interested in pursuing it and he'd be dead of cancer within five years. It's doubtless that he'd be Elon's Chief Architect at SpaceX today. Bad Motherfucker. These features never seem to mention the significant role he played in the Civil Rights Movement, desegregation of Alabama, funding towards historically black colleges and inclusion of minority hires at NASA. Perhaps not the best person, but an Absolute Giant of a Man.
