iss062e014339 (Feb. 16, 2020) — NASA astronaut and Expedition 62 Flight Engineer Jessica Meir configures the Light Microscopy Module inside the Fluids Integrated Rack. The specialized microscope is being readied to examine the transition of an ordered crystal to a disordered glass to determine how increasing disorder affects structural and dynamic properties. The Advanced Colloids Experiment-Temperature-4 (ACE-T-4) investigation controls disorder by controlling temperature in a series of samples and observes the microscopic transition in three dimensions.
