NASA Proposes Manned Asteroid Mission

eldavojohn writes "NASA has proposed a manned asteroid mission to a near earth object. They mention this being viewed as a "gap-filler" to keep the public's attention between a lunar exploration & manned mars mission. The article also cites these goals as in line with the Constellation Program. From the article, 'Furthermore, a human venture to a space rock may well accelerate precursor robotic surveys of asteroids, Schweickart observed. "Early unmanned visits to asteroids ... it's the same pattern as we did with the Moon and we're doing right now with Mars. It's all pretty logical," he told SPACE.com.'"

Well, it'd be more expensive to ship all the tools from earth and make it in space than to just make it on the earth and bring it into space. But when it costs you about $10,000 per kilogram to get something into orbit, it doesn't take long before refining and manufacturing in space becomes much more cost efficient than transporting everything from earth. The initial investment would be high due to the fuel required to lift a friggin' refinery into space, but after that your costs are minimal.

      So, for instance, if you wanted to build a small spacecraft for a manned mission to mars, it'd probably be cheaper to do it on earth. On the other hand, if you wanted to build 10 of them, or a large spacecraft capable of sustaining a good sized crew or even a colony, you'd have to do it orbit. At that scale you're talking about lifting something like 10,000 tons into orbit, and at current prices that'd cost you $100,000,000,000 (that's one hundred billion). Never mind the cost of actually building it, that's just to lift it. So it becomes much more efficient to build just the electronics on earth, and build the shell in orbit. Plus, once you have that capability, it's no longer so important to make the vehicles as small as possible, so you can start adding all sorts of nice amenities, like simulated gravity, recreational areas, and fruit and vegetable gardens. You could even supply the vehicle with soil and water from the asteroid, and just bring up seeds, fertilizer, and worms/insects from earth. Grow at least SOME of the food in orbit instead of giving your astronauts $10,000-a-plate meals.

      I don't see donation as a decent funding source, too few people would do it. So, considering your point here, I'd actually answer it in terms of private industry, and I would say companies spend the funding they have on what they know they need to do, to get whatever it is they want done.

      > You don't make product flying a plane into a hurricane, but it still needs to be done.

      But why *does* it need to be done?

      As I understand it, planes fly into hurricanes so that the course of the hurricane can be more accurately plotted and also to help long term research into hurricane behaviour to improve course prediction.

      This certainly is a useful thing to have done.

      Question is, given that resources are finite, it is actually useful *enough* to spend money on? might there not be other things even more useful which we'd rather spend the money on?

      Remember what I said in the previous post about donating money? well, consider - imagine not taxing the people who pay for this research and letting them do what they want with the money.

      Some of those people may well have a lot of financial demands upon them (family, education, health care, food, heating, etc) and not much money. Are they going to want to spend 50 dollars a year on hurricane research? no. They wouldn't ever donate that money to NOAA, even though some of them will in fact be living on the Florida coastline and will be affected by those hurricanes. It's simply that the benefit they get from improved hurricane path prediction is so small, and their needs for health and food and warmth (well, air-con in Florida I guess ;-) are so much more vital that they spend their money correctly and appropriately for themselves.

      Now, getting back to your original comment.

      "...which needs to be done".

      Well, for those people who don't donate, it really *doesn't* need to be done. It would benefit them, but much less than other things which matter more.

      Now at this point, I suspect many will still feel an instinctive "it needs to be done" response - and perhaps even think about all those people who aren't so badly off.

      But the issue remains fundamentally the same. *We* feel it needs to be done, but we are imposing our choice on other people by using taxation to fund the flights. Maybe it isn't right for them - who are we to make that decision for them?

      And if we are all left to make our own decisions, then everything that does exist will do so because people *genuinely, of their own free will, wish it to be so*, rather than having the choice imposed upon them through taxation.

If a meteor knocked a hole in your bag (pretty likely over time), you would suddenly have a second jet, and you didn't get to pick which way it's pointed, so it's effectively uncontrolled. It might hit the earth instead of orbiting. If it broke apart due to the warming, your bag is completely history.

    Plus, when was the last time somebody wrapped something that big? It would probably take hundreds of thousands of pounds of plastic, plus some sort of machine that to lay it all down. And you'd need nozzles. If you want to control it, you can't just cut a hole and call it good. And you have to the center of mass precisely, which would change as material is jettisoned, or it tumbles.

    Also, you're talking about a lot of momentum change here, from a low impulse thruster. Comets move fast through the inner solar system. It would take a lot of mass and a long time to swing it into a useful orbit.

    Probably a better idea is to land a couple solar or nuclear powered mass drivers on the comet that would actively launch material in the opposite direction you wanted to accellerate the main mass. It's still a major leap beyond what we can technically and economically accomplish right now...except perhaps if we found ourselves absolutely needing to and we had enough time.

  64. Need new ways of doing things by maddogsparky · · Score: 1

    People do things the same way until they think of a better way. I hear a lot of people talking about "in-situ resource utilization", but most seem to be thinking of trying to duplicate what is currently done in the industrialized world. What they seem to gloss over is the need for the tools to make the tools to bootstrap in-situ industry in space. This is sort of like saying, how do you make a blacksmith shop (used for making other tools and finished goods) when you have limited carrying space on your person or in your covered wagon?

    How about a new series of contests with prizes related to developing items using only the resources available in a certain local? For example, have a student competition that starts with dirt, sand, clay, etc. from a given area and challenge them to build something. One contest could be for simply developing a container. Simple, you say? What if the resource available is just sand? Granite? You could allow the use of other materials, but heavily penalize the use of consumables. Various levels of award money could be available for making a container capable of holding a liquid or even an air-tight container (bonus points for higher pressure capacity before bursting).

    Another contest could be for creating electronic components using "in-situ" resources. Conductors, insulator, resistor, semiconductor, etc. are all needed for modern manufacturing. Also, contests for creating things like heating elements, power generators/collectors, etc. would be good for creating industrial components.

    Some people have talked about using solar ovens, etc. as a means for making these things. Lets put it to the test! Its science fiction or speculation until somebody actually does it. Once people make progress in these areas in the public arena, you'll start to see some of the more successful ideas adapted for real missions.

    Wouldn't it make a lot more sense to send miners with big drills, nukes and bruce willis? Correct me if i'm going in the wrong direction here.

    Forget that!

    1. Send robots. Find out what the asteroids are made of. NASA Should PR the crap out of this.
    2. Send people. Mine them sumbitches!
    3. Soft land mined materials back to earth.
    4. Make inorganic raw materials so cheap as to be economically valueless. Like grass or wood or
          minerals in Starcraft.
    5. Ravage various economies.
    6. Profit!

    YMMV on steps 1-5. But at least I've solved that nasty ???? between ideas and profit!
