Abstract

To this author’s knowledge, the first paper dealing with the problem of making a spacecraft exit the solar system at the maximum possible speed was published in 1972 by [1]. The abstract of his paper summarizes his results: “For optimum propulsion energy management, the departing spacecraft should use a powered flyby maneuver at Saturn for insertion into a retrograde heliocentric orbit, followed by a Jupiter gravity-assist for injection into a hyperbolic orbit such that a final powered maneuver is applied at closest perihelion distance and highest perihelion approach velocity possible.” Later, an algebraic error present in Ehricke’s paper was corrected by [2]. Again we quote from the abstract: “An error in some previous considerations of gravity-assist interstellar propulsion is pointed out and corrected. The revised analysis is applied to powered and unpowered periapsis maneuvers.”
