In 1985, astronaut Buzz Aldrin proposed his Aldrin cycler as a better way to get to and from Mars. It's a very fun idea, but I thought there was room for improvement. I looked through the database and found an asteroid that happens to have just about the right orbit to be a Mars cycler. Thus, we have...the Itokawa Cycler.
