Abstract
Low-energy lunar transfers (LETs) utilize three-body mechanics with fourth-body
(solar) perturbations to provide an alternative to direct lunar transfers. The offer
of reduced lunar orbit insertion cost in exchange for longer time-of-flight and
potentially higher transfer insertion cost presents an interesting trade-off when
planning the logistics of multi-mission lunar exploration campaigns. This is particularly
true for logistics featuring spacecraft with a variety of launch vehicles
and propellant types, as the logistics of each spacecraft are impacted by the costs
and benefits of LETs differently. This paper presents a translunar logistics model
featuring LETs, discusses the trade-offs versus direct transfers through some case
studies, and highlights the scenarios in which LETs prove most useful.
