A NASA spaceflight program, exploits a unique, holography-based, diagnostics tool to test and apply a more general analysis of particle motion in viscous flows. The theory describes particle dynamics and heat transfer in a microgravity environment. After the main features of the analytical solution have been validated it will be used as a tool for making additional measurements of the microgravity environment. Our experiment will be optimized for testing the model, measuring g, g-jitter, and other microgravity phenomena. We will also collect data for which no current theory exists. Ground experiments and analysis have been conducted by the investigator team to support the flight experiment.
