THE RING-SHEARED DROP (RSD NNX12AQ22G PI: HIRSA) PROJECT WAS INSPIRED BY THE POSSIBILITY OF MICROGRAVITY EXPERIMENTS WITH CENTIMETER-SCALE (AND LARGER) LIQUID SYSTEMS WITHOUT A CONTAINER WHERE SURFACE TENSION PROVIDES CONTAINMENT OF THE LIQUID AND MIXING IN THE BULK IS CONVEYED BY THE SURFACE SHEAR VISCOSITY. THE RSD TECHNOLOGY WAS ORIGINALLY DEVELOPED TO STUDY THE FORMATION OF AMYLOID FIBRILS WHICH PLAY A CENTRAL ROLE IN MANY NEURODEGENERATIVE DISORDERS INCLUDING ALZHEIMER S DISEASE AND PARKINSON S. THE RSD MODULE FOR THE AMYLOIDOGENESIS STUDIES IS UNDER CONSTRUCTION IN HUNTSVILLE AL FOR DEPLOYMENT ABOARD THE ISS IN 2019.
