Transcription: One of the things we've learned to do in the microgravity environment of space is to be able to grow crystals, in this case protein crystals that are used in a variety of applications in pharmacology. Our biggest job after activating the experiment, going ahead and mixing the ingredients, the precipitates that would help to form the crystals, was to do some photography of it. We did activation photography to capture what the experiment looked like as we started up.
