As I document research in the polar regions, I'm also interested in how people spend their free time when they're so far from civilization. Ronny Engelmann, a scientist with the Leibniz Institute for Tropospheric Research, donned a space blanket to become C-3PO for a Halloween party on the icebreaker Polarstern. Dressing up was mandatory. And since expedition participants did not bring along costumes, they had to improvise with materials found on the ship.
