The millionaires leading mankind's march to space have a few things in common — in particular, starry-eyed visions of sending humans to the final frontier and galaxy-size bank accounts to launch their ideas into orbit.
"This Millionaire Has a Promising Idea for Space Exploration. But He Says Aliens Are Already Here." is from the May 31, 2017 Speaking of Science section of The Washington Post. It was written by Cleve R. Wootson Jr. and narrated by Jill Melancon.
