If the propellant required to reach a particular cycler from the Earth and from the Moon is modest and the transit time between the two bodies along the cycler is reasonable, then having a spacecraft on thecycler can provide an important component of an economical space transportation system. Cyclers may also be useful for navigation satellites (Satellite navigation).Cycler orbits are potentially useful for transporting people or materials using little propellant. Instead, they rely on gravity assist maneuvers to keep them going with occasional powered corrections (Orbital maneuver) to maintain the trajectory. These trajectories should have the characteristic that they can be easily targeted for either launch or destination planet and that the times between encounters yield a reasonable stay time on the destination and provide for both routine and emergency return on a fairly regular basis."@en }
