It was probably one of the best tribute to Hitchhiker for its 30th anniversary. While the LCROSS spacecraft crashed towards the moon on 9 October, its twitter feed quoted the words of the spermwhale that fell towards its death on the planet of Magrathea:

“And what’s this thing coming toward me very fast? So big and flat and round,
4:34 AM Oct 9th from web

it needs a big wide sounding name like ‘Ow’, ‘Ownge’, ‘Round’, ‘Ground’!”

“That’s it! Ground! Ha! I wonder if it’ll be friends with me?”
4:34 AM Oct 9th from web

How cool is that? Thanks NASA! (and thanks to Jan for the info)
