This paper studies how to optimize spacecraft trajectories for Jupiter missions that use single-satellite-aided capture, aiming to reduce the Δv needed to enter a nominal Jovian orbit by leveraging a gravity assist from one of the Galilean moons. Using Jupiter arrival excess velocity and arrival time to link the planetary segment with the nominal orbit, the authors develop and test an integrated optimization method (with VEGA and VEEGA gravity-assist sequences) in numerical simulations and report reliable convergence when complete mission orbits are achieved. A stated limitation is that prior work is emphasized as having mostly focused on Jovicentric orbits, and the new method likewise targets Jovicentric orbits as its primary optimization setting. Relevance to endometriosis: the paper does not explicitly discuss endometriosis or adenomyosis; it was included in the corpus via a keyword match in the upstream search index.

Abstract

In Jupiter missions, single-satellite-aided capture employs the gravity assist of one of the Galilean moons, which could decrease the required Δv to capture a spacecraft into the nominal orbit around Jupiter. Previous studies on single-satellite-aided capture mainly focused on Jovicentric orbits. In this paper, an optimization that focuses on Jovicentric orbits and considers the planetary segment and the nominal orbit around Jupiter was proposed. We use Jupiter arriving excess velocity and arriving time as the link between these two segments, which clearly illustrates single-satellite-aided capturing. VEGA and VEEGA sequences (both planetary gravity assist sequences) are tested in the numerical simulation. The result, with the complete orbits of the mission, indicates the reliability and good convergence of the method. It also turns out that Io and Ganymede are the first options for satellite-aided capture.
