Crystallization of the collagen-like polypeptide (PPG)10 aboard the International Space Station. 3. Analysis of residual acceleration-induced motion.

(PPG)(10) crystallization experiments onboard the ISS using the Advanced Protein Crystallization Facility have shown parallel and coherent crystal motions. The residual acceleration profiles and the History of the ISS Increment 3 mission allow a quantitative interpretation of these motions. Two events determine the observed crystal motions: the undocking of the Space Shuttle and a change in the ISS attitude required for power generation. No correlation between these motions and the crystal quality is apparent.
