Titan Sample Return Mission Using V-Infinity Leveraging

The unique environment of the Saturnian moon Titan provides a particular incentive for a sample return mission in the mid twenty-first century. The thick atmosphere and low gravity provide both useful benefits and harrowing challenges that make optimizing the return trajectory, whether for time of flight or ΔV, especially important for such a long-term mission in order to maximize return. V-infinity leveraging provides a unique capability for finding epoch independent, reduced ΔV return trajectories which can be reliably converged from theoretical results. This paper will demonstrate the ability to use this technique to enable Titan sample missions and examine it relative to other options.

Effect of V-infinity Leveraging with Lunar-earth Gravity Assist on Interplanetary Trajectories

This work evaluates the effects of Lunar-Earth Gravity Assist on mission design and DV budget for interplanetary trajectories using Earth flybys and V1 Leveraging Maneuvers. The use of the Moon flyby, in combination to the Earth flyby, provides additional deviation of the hyperbolic excess velocity with respect to the Earth, also modifying its magnitude, and hence increases the overall flyby performance. The Lunar-Earth Gravity Assist has been evaluated for Exterior and Interior Leveraging, as well as for Short and Long transfers. A sample Jupiter mission is showcased, and the results suggest that the Moon effect during the flyby can reduce the total DVtot by 6.4% and the leveraging DVVILM by 21.06%.
