From the Geocaching.com blog:
Geocaching is heading towards the International Space Station (ISS). All of geocaching? No, not all of it, but a very special little Travel Bug® named TB5JJN1 is tagging along with Nasa astronaut Rick Mastracchio on his mission to the ISS. Mastracchio will be using the Travel Bug as an educational tool to help teach students around the world about geography and geocaching.
Mastraccio will Rocket into Space on November 7, 2013 (GMT). Every geocacher who attends a Geocaching Event on November 6 or 7, 2013 will be awarded a “Geocaching in Space” souvenir. In additional, Geocaching in Space Mission Patches will be sold, and proceeds will to the educational charity DonorsChoose.org.
