iss062e014349 (Feb. 16, 2020) --- A view of NASA astronaut Jessica Meir configuring the Light Microscopy Module (LMM) for the Advanced Colloids Experiment-Temperature-4 (ACE-T-4) science in the Destiny module aboard the International Space Station (ISS). Introducing disorder to a crystalline system in a controlled way can form glass. Advanced Colloids Experiment-Temperature-4 (ACE-T-4) examines the transition of an ordered crystal to a disordered glass to determine how increasing disorder affects structural and dynamic properties.
