The work will be organized as a collaboration between JPL and two external partners: Arizona State University and Meteorological Product Inc. (Mylar manufacturer). Objectives: EM Analysis and feed antenna re-design (JPL): Design of an array feed to compensate for surface curvature, fabrication and test together with the inflatable membrane in the anechoic chamber. Pressure control for the MESA test (JPL): Use of a pressure control system to ensure correct inflation and maintenance of the desired shape during the MESA test. Mechanical Analysis (JPL): Development of a canister and of a mechanism for storage and deployment. Inflation system reliability (ASU): Development of a mechanism to control the release of the powder at the beginning of the inflation, and development of a UV curing rigidization system with experimental tests. Antenna prototyping (MPI): Prototype fabrication. Control analysis (JPL): Test at the SSDT for attitude dynamics, including antenna pointing and disturbances’ characterization.
