ISS Star Trail Photography By Donald Roy Pettit

In November 2008, Pettit invented a zero-g coffee cup, which used the wetting angle to carry the coffee along a crease to permit drinking and avoid the necessity of a straw. This zero-g cup was featured in the May 2009 National Geographic Magazine issue, along with his notes on the relation of the internal cup angle to the contact wetting angle for various construction materials.
Antarctica
From November 2006 through January 2007, Pettit joined the Antarctic Search for Meteorites (ANSMET), spending six weeks in the Antarctic summer collecting meteorite samples, including a lunar meteorite. During the expedition, he was called on to perform emergency electrical repairs to a snowmobile and emergency dental surgery. Periods of tent-confining inclement weather were spent continuing his Saturday Morning Science series—"on Ice"—with photographic surveys of crystal sizes of glacial ice samples and collections of magnetic micrometeorites from ice melt used for cooking water. (He estimated Antarctic glacial ice to contain roughly 1 micrometeorite per liter.)
