Microgravity

Mission Specialist George (Pinky) D. Nelson uses a 35 mm camera to photograph a protein crystal grown during the STS-26 Protein Crystal Growth (PCG-II-01) experiment. The protein crystal growth (PCG) carrier is shown deployed from the PCG Refrigerator/Incubator Mocule (R/IM) located in the middeck forward locker. The R/IM contained three Vapor Diffusion Apparatus (VDS) trays (one of which is shown). A total of sixty protein crystal samples were processed during the STS-26 mission.
