1.	Grover, Piyush, et al. (författare) Optimized Three-Body Gravity Assists and Manifold Transfers in End-to-End Lunar Mission Design 2012 Ingår i: Advances in the Astronautical Sciences (Spaceflight Mechanics 2012: Proceedings of the 22nd AAS/AIAA Space Flight Mechanics Meeting). - 0065-3438 .- 1081-6003. - 9780877035817 - 9780877035824 ; 143 (2012), s. 1189-1203 Konferensbidrag (refereegranskat)abstract We describe a modular optimization framework for GTO-to-moon mission design using the planar circular restricted three-body problem (PCR3BP) model. The three-body resonant gravity assists and invariant manifolds in the planar restricted three-body problem are used as basic building blocks of this mission design. The mission is optimized by appropriately timed delta-Vs, which are obtained by a shooting method and a Gauss-Pseudospectral collocation method for different phases of the mission. Depending upon the initial and final orbits, the optimized missions consume between 10-15 % less fuel compared to a Hohmann transfer, while taking around 4 to 5 months of travel time.
