# Powered Earth-Mars Cycler with Three-Synodic-Period Repeat Time

@article{Chen2005PoweredEC, title={Powered Earth-Mars Cycler with Three-Synodic-Period Repeat Time}, author={K. Joseph Chen and T. Troy McConaghy and Damon Landau and J. M. Longuski and Buzz Aldrin}, journal={Journal of Spacecraft and Rockets}, year={2005}, volume={42}, pages={921-927} }

We construct a cycler (with acceptable transfer times and moderate encounter velocities) by patching a series of three-synodic-period semicycler trajectories together. The cycler employs high-efficiency low-thrust propulsion for trajectory maintenance and correction (thus making it a "powered" cycler). Even though the propellant usage is not insignificant, we believe that this cycler still compares favorably with ballistic cyclers (that is, cyclers that do not require deterministic maneuvers… Expand
