NASA astronaut Serena Auñón-Chancellor mixes protein crystal samples

iss057e074528 (Nov. 9, 2018) --- NASA astronaut Serena Auñón-Chancellor is pictured in the Japanese Kibo lab module mixing protein crystal samples to help scientists understand how they work. BioServe Protein Crystalography-1 (BPC-1) seeks to demonstrate the feasibility of conducting protein crystal growth in real time aboard the International Space Station. Crew members add solutions to the hardware, observe the crystals that form and adjust for follow-on experiments.
