    Buzz Aldrin? What happened to Arnold Swartzenegger going to Mars?
  • Goddamnit! I want to listen to Wayne Newton for the entire trip to Mars! And to Tom Jones on the way back!

    Why must everyone ruin my dreams?

    A couple of comments. First, this is an old idea - cyclers have been proposed for over 20 years and Aldrin's seminal addition to the concept was made in 1985 - see here [sciam.com] for details. My question is, why is this meme back in the public consciousness NOW? It can't be because Aldrin thinks Bush will support the concept now that he's Prez; the new Bush NASA is going exactly the opposite route than cyclers with their sudden support of nuclear propulsion [space.com]. Second question, where did the sudden push for NASA nukes come from? Especially at the expense of previously planned missions to Pluto and Europa [spacedaily.com]? And my third question, why is space so passe to Slashdotters and by extension tech oriented fans in general? All the space articles on Slashdot get one-tenth to one-quarter the postings of just about any other topic; if even the geeks don't care about space that much any more, how can we ever hope to have a stable space program instead of this outer plane probes / no wait, nuke rockets / no wait, cyclers mass confusion?
    • My question is, why is this meme back in the public consciousness NOW?
      Maybe it's because the 33rd anniversary of the first Moon landing is coming up? Or maybe that's how long it takes to get the news media to pay attention to an idea about space. Or maybe a reporter thought this was a gosh-wow neat idea because he'd never heard of it before (because he never bothered studying space, as most reporters don't) so he thought it would make a good article for his equally-ignorant readership. Whatever it is, it's pathetic.
      Second question, where did the sudden push for NASA nukes come from?
      The Bush administration is pro-nuke in general. It makes a certain amount of sense to push them for space, where the energy/mass ratio is so much more important than for anything on terra firma.
      And my third question, why is space so passe to Slashdotters and by extension tech oriented fans in general?
      First man in space was over 40 years ago. The last manned moon landing was over 30 years ago. To the average geek, the World Wide Web is now and s/he can have a lot of fun (and get a job) getting hands dirty hacking with the code. Space stuff is before they were born, making it pre-history, their parents' generation's stuff; it's passé. It's also locked up behind requirements of graduate school and other barriers which keep them from having a chance to play with it, so they migrate to the things which are accessible.

      Hey, it's speculation, whaddaya want?

      • > Maybe it's because the 33rd anniversary of the first Moon landing is coming up?

        Yeah, and we could have had this meme hit public consciousness on the 30th anniversary of the moon landings, but some doofus decided to Darwin himself out of the gene pool by flying his plane in conditions he wasn't trained for, and the media completely forgot about anything else for the rest of the month.

        Along those lines, allow me to draft an open letter/rant to celebrities in showbiz and politics:

        I hereby request that for the 33rd anniversary of the lunar landings, that all celebrities and politicians kindly take one day off from slashing your wives' throats, letting your drunk chauffeurs drive you home, running into trees while playing football, skiing into trees, flying in dense fog, playing golf in thunderstorms, or standing on tops of hills in copper bathtubs raising lightning rods to the skies screaming "ALL GODS ARE BASTARDS!", or whatever else it is that celebrities do to attract attention.

        Just one fscking day.

        Thanks to a society that preferred celebrities like you, I'll never see ultra-mega-huge-baseline interferometric data from the worlds around other stars. Thanks to you, I'll never see pictures of what's under the ice of Europa. Thanks to you, I know I'll never see anyone, let alone me, set foot on Mars. Thanks to you, I know I'll never see goddamn low earth orbit, let alone explore another world.

        The dinosaurs went extinct because their walnut-sized brains weren't enough to permit them to develop a space program. From where I sit, I see the odds of being wiped out by asteroid impact as far greater than the odds of seeing any significant manned space exploration in my lifetime. Maybe it'll serve us right.

        The saddest thing is that I'm part of that transitional generation that did have hope of exploring the solar system in our lifetime. I grew up believing that happiness was looking at Earth in my rear-view mirror, and the realization that we traded it for a world of "punch the monkey" banner ads is a hell of a comedown.

        Rant mode off. Thanks for reading.

        • Hey, don't give up hope. We may get out there yet. It seems like strip-mining the asteroid belt is starting to become a popular idea, so maybe if we're lucky some corporation will let us tag along for the ride.

          I know what you mean though. It's depressing to think about all the things we can't do because of the lack of technology. But just think of the oportunity we do have: To study physics before everything is known. You could be the first one to nail down a solid set of equations describing everything. Now that would be nice.
  • While the technical details must be massive, in computing courses for the transports, the details, likeuseing empty fuel tanks to build the crafts, useing multiple ships etc are practical, rather than send one ship, and say "tough it out".

    Of course, the satement about once you go there, you keep going there is one that makes a good point. There's no point in going, in spending all the capital just to do it once, you keep going and keep learning. Who knows where you might end up.
  • The problems people face on the trip are radiation damage and muscular degeneration. To combat these you need shielding (several feet of rock to stop cosmic rays) and artificial gravity. I don't see how a cycler made out of spent fuel tanks is going to provide a good meteoroid shield, let alone a solution to these big problems. It looks more like money wasted.

    Now, if Aldrin was talking about cyclers made from small asteroids he'd be talking about enough size to embed a large centrifuge inside a shielded volume. But that's not what he's talking about (probably because the people in government are thinking about asteroids as weapons of planetary destruction, and at that scale they're right).

      Cosmic rays are not a problem on journeys of less than half a year - a round trip to Mars and back exposes an astronaut to less radiation from cosmic rays than people living in Aspen, CO, will recieve in their lifetime.

      The biggest radiation hazard comes not in the form of cosmic rays but gamma and x-rays from large solar flares. The prompt does from a solar flare could exceed 100 rem total, which would kill a crew in a cycler such as Aldrin seems to advocate.

      As for the muscular degeneration problem, there isn't one. Yes, in microgravity astronauts experience muscule and bone loss. However, there is a lot of things that can be done to slow this process, without resorting to centrifuges to simulate gravity (which is probably the easiest solution...). Soviet cosmonauts who spent between 6 and 18 months in orbit have shown rapid recovery from the effects of microgravity exposure.

      The greatest problem facing a manned mission to Mars seems to be public apathy and lack of focus at NASA. This is why heroic figures like Buzz Aldrin are getting involved, to bring the discussion to the public view, and motivate the appointed officals who oversee the manned space program.

      • > The prompt dose from a solar flare could exceed 100 rem total, which would kill a crew in a cycler such as Aldrin seems to advocate.

        Leaving aside the issue of shielding the crew, it's a cycler. It'll come back.

        What were the odds of a sailing ship making it from Spain to the New World in 1492 BC?

        (Better yet, what were the odds of a grass boat making it halfway across the Pacific in 10,000 BC?)

        But people did it. People took the risk back then. Sure, some came for the gold and furs and population of pagans to convert, but they also wanted a chance to expand/explore stuff. Whatever their reasons, they took risks that by modern standards would be madness.

        If there were a 10% chance of being fried to a crisp, and a 90% chance of setting foot on Mars and helping set up or grow a colony, (if the crew gets fried en route, no need to waste a pricy lander, just send the cycler, with lander, back to Earth and pick up a new crew!) you'd still have thousands of volunteers.

        It's better odds than the New World's settlers had. It's incredibly better odds than those faced by the Polynesians. I'd fly tomorrow. Who's with me?

        • The MAGER experiment aboard MGS pretty much showed that a manned colony on mars is probably never going to happen (or atleast not for a really long time) due to terrible surface radiation.

          It is of course possible to shield against this, but you're no longer talking about a mission that'll come in under $100 billion.
    • Actually, if I remember correct the crew could be shielded in a container of water about 18" thick on all sides. The configuration could be that the water would be stored in the outer hull of the living quarters and create a safe zone. Considering how much water they would want to take anyway this doesn't sound like a bad idea with the exception that water is fairly heavy to get up into orbit.
      • The water shield is okay for stopping solar flare protons. The problem is that the water creates more radiation from cosmic-ray particles than it stops; the secondary particles will kill you. You either want as little mass as possible between you and the outside (to prevent cosmic rays from creating secondary particles) or at least ten tons per square meter to stop everything.

        Thing is, for a cycler that's doing its orbital corrections with something like a solar sail, I don't see why you can't have ten tons per square meter. It would let crews ride the cyclers indefinitely, instead of being limited to one or two spins in a lifetime.

      • I thought that Mini-Magnetospheric Plasma Propulsion (M2P2) [nasa.gov] was supposed to solve this problem.
        For human travelers the greatest advantage of M2P2 might not be steady acceleration or fuel efficiency, but rather its impressive safety features. Just as the Earth's magnetosphere protects us from solar radiation, an M2P2 bubble
        could shield spacefarers from cosmic rays and solar flares.
        Emphasis mine.
  • Buzz 'co-wrote' a novel on this concept about 5 years ago.
    It's called Encounter with Tiber [amazon.com]. It deals with a failed alien colonization of earth in prehistoric time due to their plant dying off. Present day - humans use the alien technology to try and locate these aliens - not a bad book

    Buzz Alrin's idea of a hotel travelling to mars and back is not nuts. No more nuts than Christopher Columbus trying to sail to India.

    What is nuts, is spending over 2 TRILLION dollars on bombs and warplanes. That much money could easily fund a space colony, and move humanity's constructive technology to the level of its destructive technology.

    One thing that bugs me about how people understand space is they think of it as enormous distances of emptiness speckled by dots of dust. This view is ignorant and limited. Though by earth standards the distances between the planets is astonomical, the idea is rendered meaningless by the astronomical speeds reached. Spaceships could travel between the planets in shorter times than ships cross the ocean with engines designed for it. Thinking of the planets and asteroids as lifeless dustballs is also off the mark; do you think of a field as a lifeless patch of dirt? Probably so. But, with vision, those lifeless dustballs could be turned into power and food generating plants that could power the earth and solve world hunger. All it takes is imagination and ingenuity.
