Mars cycler is recorded in this encyclopedia from the source named below.
Overview
A Mars cycler (or Earth–Mars cycler) is a kind of cycler, a spacecraft with a trajectory that encounters Earth and Mars regularly. The Aldrin cycler is an example of a Mars cycler. Cyclers are potentially useful for transporting people or materials between those bodies using minimal propellant (relying on gravity-assist flybys for most trajectory changes) and can carry heavy radiation shielding to protect people in transit from cosmic rays and solar storms.
