Don't panic! This is the story of a book, a book called The Hitchiker’s Guide to the Galaxy, a wholly remarkable book.<br /><br />ESA astronaut Samantha Cristoforetti reads from Douglas Adam’s “The Hitchhiker’s Guide to the Galaxy” for towel day from the European laboratory Columbus on the International Space Station.<br /><br />The Guide has a few things to say on the subject of towels. A towel, it says, is about the most massively useful thing an interstellar hitchhiker can have.<br /><br />To all you froods on the mostly harmless planet Earth, happy towel day!<br /><br />Towel Day is an annual celebration on 25 May, as a tribute to the late author Douglas Adams when fans around the universe proudly carry a towel in his honour.
