Development of the Deployable on-Orbit ultraLight Composite Experiment (DOLCE) for the Space Solar Power Project Demonstration Mission

View Video Presentation: https://doi.org/10.2514/6.2022-1266.vid We describe the development of an engineering model of the DOLCE payload which will demonstrate on orbit for the first time the deployment of an ultralight Caltech SSPP structure. Deployment tests at the subsystem and system levels, launch load analysis and testing, and accelerated aging tests have been conducted. The DOLCE payload will be launched with the SSPD-1 mission which will demonstrate space-based solar power key enabling technologies in photovoltaics, power beaming, and deployable structures.
