Why can't I request a hard copy of NASA's Spinoff 2017?

Here for Spinoff 2017. It says "To request a free print copy of the book, contact us." However, when I click contact us, it doesn't take me anywhere. Is anybody able to actually have that link take them to request a copy of it or is it just me?
