THE GOAL OF THIS PROPOSAL IS THE DETERMINATION OF DESIGN PARAMETERS FOR THE RING-SHEARED DROP (RSD) MODULE RECENTLY AUTHORIZED TO PROCEED TO FLIGHT ABOARD THE INTERNATIONAL SPACE STATION (ISS). THE TECHNOLOGY CURRENTLY UNDER DEVELOPMENT JOINTLY BY RENSSELAER POLYTECHNIC INSTITUTE MSFC AND GRC IS A NOVEL PROJECT THAT WILL EXAMINE THE EFFECTS OF SHEAR AT FLUID HYDROPHOBIC INTERFACES ON AMYLOIDOGENESIS ("AMYLOID FIBRIL FORMATION IN MICROGRAVITY: DISTINGUISHING INTERFACIAL AND FLOW EFFECTS" NNX13AQ22G). THE ABILITY TO STUDY SHEARING FLOW IN ABSENCE OF SOLID WALLS AND BUOYANCY-DRIVEN CONVECTION IS UNIQUE. AMYLOID FIBRILS ARE OF SIGNIFICANT INTEREST DUE TO THEIR CENTRAL ROLE IN A NUMBER OF NEURODEGENARATIVE DISEASES INCLUDING ALZHEIMER'S AND PARKINSON'S AS WELL AS THEIR ROLE IN TYPE-2 DIABETES.THIS FO PROPOSAL IS DESIGNED TO USE PARABOLIC FLIGHT TESTING FOR A "DEMONSTRATION OF SPACE TECHNOLOGY PAYLOADS" AND TO COLLECT THE DESIGN DATA THAT WILL ENSURE SUCCESS OF THE RSD MODULE FOR ITS FLIGHT(S) ABOARD THE ISS. IN FEBRUARY 2016 THE FIRST PARABOLIC FO SUCCESSFULLY DEMONSTRATED PINNING OF WATER DROPS AT 10 MM SCALE. THE RESULTS FROM THAT FLIGHT CAMPAIGN ALONG WITH LABORATOR-BASED EXPERIMENTS AND NUMERICAL SIMULATIONS WILL APPEAR IN THE JOURNAL MICROGRAVITY SCIENCE AND TECHNOLOGY. THE NEW PROPOSAL SEEKS TO STUDY DROP FORMATION USING PROTEIN SOLUTIONS AT A SCALE OF 15 MM IN A PROGRESSION TOWARD THE 25 MM SCALE OF THE RSD MODULE ABOARD THE ISS.
