Dual Jupiter Swing-by Trajectory for Interstellar Probe

摘要

One main mission objective of the Interstellar Probe mission is to accelerate a spacecraft to an escape velocity of 95 km/s at infinity and to reach a distance from the Sun of 1,000 AU within 50 years after launch, with a launch date between 2030 and 2040. This paper presents a preliminary trajectory analysis in which different options have been analyzed in order to achieve such a high solar system escape velocity. A fundamental constraint applied to this analysis is the use of existing technologies to generate the required AV. An interesting option revealed by this analysis is a dual Jupiter swing-by trajectory in which a first Jupiter fly-by is used to re-direct the probe towards a very close powered Sun fly-by, also known as Oberth Maneuver, which is then followed by a second Jupiter fly-by.
