ISS Star Trail Photography By Donald Roy Pettit

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.)
