IN-STEP inflatable antenna experiment

Abstract

The objectives of the NASA In-Space Technology Experiments Program (IN-STEP) are to validate the deployment of a 14-m inflatable parabolic reflector structure, measure the reflector surface accuracy, and investigate structural damping characteristics under operational conditions. Here, the accomplishment to date and the approach planned for the remainder of the experiment are discussed. In particular, attention is given to the experiment subsystems, the mechanical thermal, and structural characteristics of the reflector, and the ground-based test program.
