Purpose

The Physics of Hard Spheres Experiment (PHaSE) is a NASA Lewis Research Center fluid physics space flight experiment whose purpose is to investigate the behavior and physical properties of a colloidal dispersion of hard spheres. The Microgravity Science Division of the NASA Lewis Research Center has the responsibility of implementing the PHaSE space flight experiment.

The investigative approach is as follows:

Continue ground based experiments at Princeton University
Conduct a single angle light scattering investigation, Colloidal Disorder-Order Transition (CDOT), utilizing Glovebox investigation on The Second US Microgravity Laboratory (USML-2) in 1995.
Conduct a multi-angle light scattering experiment, PHaSE, on the Microgravity Science Laboratory-1 (MSL-1) in April of 1997.
Perform additional experimental measurements aboard the MSL-1 re-flight (STS-94) scheduled for July 1, 1997.
Conduct possible further multi-angle light scattering investigations on the Space Station Fluids Facility.
