Impulsive Trajectories from Earth to Callisto–Io–Ganymede Triple Flyby Jovian Capture

“…(This collection of trajectories was generated using a similar method to that of Lynam [25,26].) Candidate selection was performed by first choosing to use an incoming rather than outgoing Earth flyby trajectory and then eliminating all trajectories without an equatorial Callisto flyby; this reduced the number of candidates to approximately 300.…”

“…The methodology contained within refines the heuristic reduction methods that Lynam used to find triple-satellite-aided capture sequences. Further, this paper concentrates on finding ballistic trajectories from Earth to Jupiter that would use chemical propulsion rather than the low-thrust trajectories that Lynam [25,26] used. This paper features the use of a broken-plane maneuver (BPM) to ensure that the spacecraft's original trajectory plane intersects with an Earth encounter and that its final trajectory plane is coplanar with the orbits of the Galilean moons.…”

“…Lynam [25,26] developed a method that was able to find promising trajectories for two of these eight permutations: Callisto-Ganymede-Io-perijove and Callisto-Ganymede-perijove-Io. This paper builds on the work of Lynam by investigating one of the other six permutations: the Callisto-Io-perijove-Ganymede sequence.…”

“…Although most papers discussing satellite-aided capture have focused on using only one satellite gravity assist to aid in the capture [13][14][15][16][17][18], several have proposed using two [19][20][21][22][23] or three [21][22][23][24][25][26] of Jupiter's Galilean moons to capture a spacecraft into orbit about Jupiter. Using three gravity-assists of Jupiter's Galilean moons is called "triple-satellite-aided capture".…”

Impulsive Trajectories from Earth to Callisto-Io-Ganymede Triple Flyby Capture at Jupiter

“…The use of gravity assists of planetary moons to reduce the ΔV required to capture into planetary orbit is called "satellite-aided capture". While most papers discussing satellite-aided capture have focused on using only one satellite gravity assist to aid in the capture [13][14][15][16][17][18], several have proposed using two [19][20][21][22][23] or three [21][22][23][24][25][26] of Jupiter's Galilean moons to capture a spacecraft into orbit about Jupiter.
