Technology Recommendations for Enabling Future Planetary Science Missions with Aerocapture

Abstract

Aerocapture offers an efficient and near-propellantless method of orbit insertion at almost all atmosphere-bearing planetary destinations. Compared to propulsive insertion, aerocapture offers considerable savings in propellant mass which could be used to accommodate more scientific payload. Aerocapture is particularly attractive for low-cost interplanetary small satellite mission concepts.  As with any space mission, aerocapture involves multiple disciplines and analyses: science, mission design, interplanetary trajectory, atmospheric guidance, navigation, and control, vehicle and spacecraft design, thermal protection system design, atmospheric models, satellite tour design, as well as programmatic, cost, and risk considerations. This report provides recommendations for developments in each of these disciplines and aims to inform space technology policy in prioritizing investments in the development of aerocapture technology for future science missions.
