Buzz Aldrin - Aldrin Cycler

Aldrin Cycler

In 1985, Aldrin proposed the existence of a special spacecraft trajectory now known as the Aldrin cycler. A spacecraft traveling on an Aldrin cycler trajectory would pass near the planets Earth and Mars on a regular (cyclic) basis. The Aldrin cycler is an example of a Mars cycler. He was also instrumental in the idea of training of astronauts underwater in order to better prepare them for the intricate space walks and duties of maintenance while in space.
