Buzz Aldrin, discoverer of the Aldrin cycler

A Mars cycler (or Earth–Mars cycler) is a kind of spacecraft trajectory that encounters Earth and Mars regularly. The term Mars cycler may also refer to a spacecraft on a Mars cycler trajectory. 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.

Earth–Mars cyclers

A cycler is a trajectory that encounters two or more bodies regularly. Once the orbit is established, no propulsion is required to shuttle betw… Continue Reading (7 minute read)
