Over the history of planetary exploration, atmospheric entry vehicles havebeen used to deliver probes and landers to Venus, Mars, Jupiter, and Titan.While the entry vehicles are tools for furthering scientific exploration, bydelivering probes and landers which perform in-situ exploration, the entryvehicle and trajectory design in itself is of significant interest. Entering anatmosphere subjects the vehicle to deceleration and aerodynamic heating loadswhich the vehicle must withstand to deliver the probe or the lander inside theatmosphere. The conditions encountered depend on the destination, theatmosphere-relative entry speed, the vehicle type, ballistic coefficient, thevehicle geometry, and the entry-flight path angle. The driving constraints arethe peak aerodynamic deceleration, peak heat rate, and the total heat loadencountered during the critical phase of the entry. Jupiter presents the mostextreme entry conditions, while Titan presents the most benign entryenvironment. This study presents a survey of the design trade space foratmospheric entry missions across the Solar System using carpet plots, alongwith benchmarks from historical missions, which can serve as a useful referencefor designing future missions.
