Buzz Aldrin's Roadmap to Mars

FleaPlus writes "Former astronaut (and MIT astronautics grad) Buzz Aldrin has an article in last months Popular Mechanics in which he describes a plan for manned Mars missions. Aldrin's plan proposes using a Cycler spacecraft permanently orbiting between Earth and Mars. This would have a shielded habitat and rotation-induced gravity, and would take just 5 months to reach Mars. Smaller vehicles would take astronauts to and from the Cycler. Aldrin claims the plan is less costly and more sustainable than NASA's current plans."

  1. Cheaper? The space industry begs to differ... by Anonymous Coward · · Score: 5, Insightful

    Buzz's plan may be cheaper than the NASA's current plan, but pass on his plan to NASA and the space industry and they'll inflate the price tag like he cannot believe.

    Still, the Congress might buy it.

    Not only is he an MIT grad with a doctorate, he's got a moon crater named after him, and he has flown into space with Homer Simpson. With credentials like that I don't know how anyone could doubt his wisdom.

    Before this feature, articles like this would simply never appear on the main page unless users configured their homepage to include all articles from the section (in this case "Science"). Now, these non-front-page articles get a small footprint at least.

    I dug around a little and found the following abstract detailing an older version of Buzz Aldrin's work. Unfortunately, I can't seem to find a free link to the actual paper...

    Evolutionary space transportation plan for Mars cycling concepts
    Aldrin, Buzz; Byrnes, Dennis; Jones, Ron; Davis, Hubert
    AIAA Space 2001 Conference and Exposition

    A promising new human Mars exploration approach based on the use of an Earth-Mars Cycling Interplanetary Transportation System is described. In this approach, a cycling vehicle acts as a permanently emplaced transportation element that continuously cycles between the Earth and Mars using gravity assist with minimal course adjustment on each cycle eliminating the need to repeat the large and expensive injection propellant requirement of traditionally conceived Mars vehicles and missions. With the implementation of a two Cycler system, one Cycler would always be going to Mars while the other is returning to Earth. When in the vicinity of the Earth or Mars, the Cyclers release or are intercepted by smaller aerobraking "taxis" that ferry people and supplies to and from the surface. Alternatively, in the Semi-Cycler Concept, the Cycler vehicles themselves would use aerobraking and gravity assist to orbit about the Earth or Mars for a period before returning. In this way, unmanned cargo flights to Mars could use the minimum energy, long trip time trajectories while crewed flights could use the shorter flight time, longer stay time options. Both concepts are addressed in the paper, and the results of preliminary flight mechanics analyses are presented. In addition, a transportation plan is presented based upon a logical extension of existing space assets augmented by new vehicles providing a reusable transportation capability.

    Seems like this guy came out up with his plans only after NASA released theirs. Story of his life, always second.

    I think NASA should just cut all the manned missions and concentrate on space probes. Much more information for the buck.

    However, I do think going to mars would be worth doing, IF they got smart about it (and yes, I realize they need the ISS for learning how to go to mars, but the ISS isn't designed to be a precursor to a mars mission). The "one way" idea I thought was worth exploring, put some risk into it, that risk might be worth taking. You know, the one where they send one rocket a year with more and more equipment, but no return fuel, only equipment later to manufacture their own return fuel and hopefully a permanent mars base.

    NASA is overly concerned with human life and the propaganda fall out of losing astronauts to be an effective exploration organization. Fireman and racecardrivers take risks in daily life, I'm sure they would find plenty of skilled volunteers for a one way mission.

  8. Read TFA and... by foniksonik · · Score: 3, Interesting

    There seem to be a lot of 'extra' expenses that his plan depends upon.... like a permanent base on the moon, a permanent fuel depot and manufacturing plant on Mars (already in place) not to mention that he calls for two Cycler type ships not one... plus the multiple CEVs to actually realize the goal of sustainability. There's more but I'll let you read it yourself.

    It's a nice plan but do I see a plan that's cheaper? Hell no, If the goal is to GET to Mars.

    If the goal is to create an interplanetary transit system then sure, this is definitely the way to go.
