 ===== Aldrin Cyclers =====
 [{{:blog:articles:general:aldrin_cycler.gif?direct&250 |A Mars cycler is an elliptical orbit (green) that crosses the orbits of Earth (blue) and Mars (red), and encounters both planets at the points where it crosses their orbits, although not necessarily on every orbit. }}]
-Cycler orbits are those that regularly visit two or more celestial bodies. Over a hundred ballistic Earth-Mars cyclers have been discovered, and hundreds more non-ballistic. Non-ballistic cyclers require some powered maneuvers. Ballistic cyclers are the most interesting ones - they can get a vessel from one planet to another at no fuel cost.

-In 1985, Buzz Aldrin - he of 2nd man on the Moon fame - calculated a cyler orbit which became known as the Aldrin Cycler. This is just one type of Mars cycler, but it's powered by an impressive vision that harks back to the scince-fiction of the 1950's. Aldrin decribes two types of vessel - taxis and castles.

 Taxis take the crew from the planet to the castle and vice versa. This is the only part of the journey requiring the expenditure of fuel. The castles permanently follow the cycler orbit, and provide both a habit of sufficient size it is comfortable for the crew, and a safe haven against the ravages of the interplanetary medium, particularly in regard to radiation.
