> After his death in 1988, Heinlein’s estate helped establish the Heinlein Prize Trust. It regularly gives out large cash awards “to encourage and reward progress in commercial space activities.” The most recent award – $250,000 – went to SpaceX founder and libertarian-minded entrepreneur Elon Musk.

But they could of course beat that: in 2016, they gave it to Bezos! So much for "large cash award"...
