Abstract

Orbit insertion at Saturn requires a large manoeuver with chemical thrusters to compensate for the velocity difference between the spacecraft and the planet. The impact that this has on the propellant budget is severe. This paper discusses an alternative strategy: after a gravity assist with Jupiter, an electrical motor with an ad hoc thrusting law reshapes the orbit and minimizes the hyperbolic excess speed at Saturn, thus facilitating the capture. The control law algorithm, as well as the dynamical and technological aspects are presented and discussed.
