Buzz Aldrin, the second man on the moon, singlehandedly calculated an orbital technique called “Mars Cycling” which would allow for spacecraft to perpetually travel between Earth and Mars with only a single initial boost. Crew would board and return via a secondary spacecraft, saving fuel.

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.

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)

    The Aldrin Cycle mothership spacecraft is still seen as the most efficient way to transport material to and from Mars. It’s quite an innovative concept.

    It would also work between Earth and the Moon

    Apparently Aldrin had a reputation around NASA and other astronauts for being cocky. But he also had a reputation for being able to back up his attitude with his skills

    How long would it take?

    He played Kerbal Space Program and travelled back to the past to tell himself how to do it.

    I met Buzz Aldrin 30 years ago. I think it was at the national air and space museum in DC. I remember looking at his name tag and saying, “pffft, your name isn’t really Buzz.” He said “Yeah it is,” or something to that effect. I walked away thinking he was an idiot.

    Years later I remembered the event, and realized it was I, in fact, who was the idiot.

    Give a guy credit when due, but Buzz only theorized it was possible from how it reads. Previous work was done 15 years earlier by someone else laying groundwork for this theory with Venus. Then according to this link he didn’t proof it, Jet Propulsion Laboratories did. I think what Buzz really did was use his status to give credibility to the idea, equally important though. The science community kind of infuriates me because as much as they are open to discovery, any ideas that are too “extreme” are laughed at. They (general term for scientists) love to criticize other scientists on more fringe topics… I experience it pretty regularly on a smaller scale. They won’t believe you til you prove it, but you can’t prove it because nobody believes you (to get funding or support ).

    Avenue 5 has taught me that they could also change course by expelling all the poo.

    Someone’s been watching Scott Manley recently…

    I too invented “mars cycling” but it involves me biking to lose weight but then consuming mars bars and perpetually staying at the same weight.

    It’s actually called the Rich Purnell maneuver.

    I love how every article has to clarify, “Buzz was the SECOND man on the moon.” Not to he confused with that total Chad Armstrong who strong armed that beta buzz out the way to be the FIRST man in the moon.

    He was nicknamed “Dr. Rendevouz” for a reason. His doctorate is in orbital mechanics. He wasnt just a pretty face, he was a smart guy at NASA…..
