Clyde Tombaugh, formerly of Streator, Illinois (Jerry Corrigan's home town), would turn 100 tomorrow. As it was, he almost made it to age 91.

I never met him, but those who did always speak highly of him.

A really small spacecraft on a really big rocket is now on its way to Pluto, really fast.

On board are some of Clyde Tombaugh's ashes.
