The system entry problem entails the capture of a spacecraft about a planet by way of propulsive maneuver(s) or flyby(s) of a planetary satellite(s), or both. In the case of the Jovian system, a balance is sought between the interplanetary time-of-flight, orbit insertion maneuver magnitude, mass delivered to the system, capture orbit period, radiation dose, and mission complexity. Based on a nominal asymptote, this paper introduces the analytical equations necessary to solve the phase-free, singly aided and doubly aided capture problems, with a focus on the doubly aided capture problem in the Jovian system. An analytical approximation for the required phasing is derived and the implications of the Laplace resonance are discussed. Analytical approximations are used to seamlessly seed a multiple-shooting algorithm in order to arrive at the converged high-fidelity solution space for the Europa Mission.
