About this work
Christiane Gumera, right, a student at Stanton College Preparatory High School in Jacksonville, AL, examines a protein sample while preparing an experiment for flight on the International Space Station (ISS). Merle Myers, left, a University of California, Irvine, researcher, prepares to quick-freeze protein samples in nitrogen. The proteins are in a liquid nitrogen Dewar. Aboard the ISS, the nitrogen will be allowed to evaporated so the samples thaw and then slowly crystallize.
