Astronaut Samantha Cristoforetti has already proven herself to be a glorious nerd by dressing like Captain Janeway aboard the ISS and taking what is possibly the best selfie ever.
She’s at it again, this time in celebration of Towel Day. She read a passage from The Hitchhiker’s Guide to the Galaxy and then waved her towel in greeting to all of us down on Earth. There were also some wonderful tweets on the usefulness of towels.
See the video and tweets after the break.
