Aerocapture at Saturn

The feasibility and benefits of using aerocapture for orbit insertion in the Saturn atmosphere are assessed in the context of existing technologies and likely science mission architectures in the Saturn system. We model aerocapture in-atmosphere flight performance in the presence of expected day-of-flight uncertainties, including those driven by limited knowledge of Saturn, to determine aerocapture flight system needs. We assess the impact of aerocapture on overall mission design for future science missions by including aerocapture in an end-to-end mission design and optimization scheme. Results indicate that aerocapture may feasible and beneficial with limited-to-no technology investment for missions designed to address near-term science priorities in the Saturn system.
