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.'"

  1. Best make sure there's solid ground by PIPBoy3000 · · Score: 3, Insightful

    If the plan is to "land" on an asteroid and plant a flag (or whatever), it's probably a good idea to actually know ahead of time that there's solid ground there. If I recall correctly, the most recent asteroid fly-bys suggested that it was mostly loose gravel held together by microgravity. Imagine "landing" and finding yourself sinking into a bunch of rocks that start flying about.

      Well, my point is that we don't have a very good understanding of asteroids. Personally I'd rather see a plan that involved a lot of robotic exploration first, with a tentative "later we'll decide if a manned mission makes sense". Doing manned missions for PR purposes seems pretty silly.

    What's the basis for NASA's planning, here?

    Science, or entertaining the public to keep the space budget healthy?

    What happens when the public start to wonder why exactly we're sending men to the Moon and Mars and asteriods, just to have them come back again? what exactly did we get for it, except the bill? saying "it's for science" or "it's advancing towards men in space" is getting *old*. We don't have an off-planet base, we're not getting one in the next ten or twenty years.

    When you consider that reality, statements like "for science" and "men in space" are ring hollow and people basically go "well, I can't see why we're doing this" and then your public support goes away.

    And no bad thing if it did. NASA has been an unmitigated disaster for space travel and exploration. It's almost entirely prevented enterprise and investment into the field and substitued expensive, slow, bureaucratic, political-football State-run snails-pace development.

    What have we got to show for the last thirty, fourty years of NASA?

    We got men on the moon and then...

    What?

    One exploration satellite every year or two? Skylab for a bit, then that came down and after thirty years, we FINALLY have the ISS...and it's in low Earth orbit. What's the point, exactly? it's a frickin' expensive way to get into space.

    Where's the innovation?

    State run companies *DO NOT INNOVATE*.

    And by God, if there's a field which needs innovation to get off the ground, it's space travel.

    We need solutions to fundamental problems. You don't get that from a committee.

      I'll answer anyway: unlikely.

      The problem with private industry is they end up needing results and showing profit. Thus long, difficult projects that don't show a good return will be scrapped. The government doesn't need to show results on a profit level, which is why they fund things like this: to promote the wellbeing and advancement of the state in ways the private sector would not.

      Personally, I like my tax dollars going to NASA as opposed to the multitude of social programs run by the state.

    The Moon is too far away and has too deep a gravity well to be really useful as a source of raw materials. An asteroid that we could break up and use to build really big spacecraft, satellites and space stations could kick start the commercial space business into high gear.

    NASA talks about this and that, shuffles around some papers, maybe changes the names of certain desk jobs, and nothing concrete comes out of it. This has been going on for, oh, a decade now (at least).

    Whether we should blame NASA, Congress or the White House for this current situation is moot. Anything NASA says about future manned missions that involve something other than putting people into low-earh orbit in an aging space shuttle is a pipe dream, isn't particularly noteworthy and I fail to see why it belongs on the front page here.

  9. Not an asteroid! by camperdave · · Score: 3, Insightful

    Capturing an asteroid for resources would be idiotic. Placing a spacecraft hull in orbit is simple. Tie together a few TransHab modules, and there you go. It is a one time cost. The real problem is consumables: Water, oxygen, propellant. You won't find usable quantities of these things on an asteroid.

    No, what you want to do is capture a comet. Thousands, if not millions of tonnes of water, which can be cracked for oxygen. Also, plenty of other ices which can be used as propellant. Launch a giant plastic bag into an intercept orbit, seal the comet inside. As the sun heats the bag/comet, vent the gas to put the comet into a more usable orbit, and voila, a mountain sized chunk of water to live off of.

    1. Re:Not an asteroid! by Gospodin · · Score: 3, Insightful

      Actually, it's only a few consumables that you'd be short of in an asteroid: hydrogen and carbon, in particular. Oxygen is abundant in most lunar and asteroid regolith. Furthermore, there's a slight difference of scale between a billion-ton asteroid and a "few TransHab modules strapped together". At current rates, launching a billion tons into LEO would cost about $10 quadrillion. While this may be a "one-time cost", it's a wee bit of steep one.

      However, you're certainly right that capturing a comet would be extremely useful. And I love the plastic bag method of propulsion! Has anyone studied this for practicality?

    Doing manned missions for PR purposes seems pretty silly.

    Not doing PR will guarantee that the entire Space Program ends up being nothing but a bunch of expensive lawn ornaments and a theme park in Florida.

    It's only because of the public interest in space, and their willingless to spend a shitload of money on it, that there is the opportunity to conduct scientific research up there at all. Private industry isn't going to pay for it; at least not on anything like the scale that we've come to enjoy today.

    The primary goal of the space program should be to ensure its own future existence, and that means keeping the public interested. If that means going and sending some guy up to stand on an asteroid for a photo op next to a flag, so be it. It's that sort of thing which will keep the money flowing.

    For 40 years, NASA has been sending astronauts into low Earth orbit and calling it "spaceflight". Dinking around in LEO is not space travel.

    OK, there was the Apollo program. That begins to count. But the Apollo astronauts were still, at all times, within the Earth's gravity well (the moon is gravitationally bound to the Earth).

    But now ... "That kind of early demonstration mission might last no more than 60 or 90 days," Durda said, "and take the crew no farther than a few lunar distances away from Earth."

    Finally. A human being is going to travel in space. Not very far. But it's a start, after decades of pitiful pretence.

    Unfortunately, it's those "average people" who control the flow of cash to scientific research, and it's their basically ignorant, baseless opinions which determine what agencies get funded and which get redlined out of existence.

    Democracy is sort of a bitch that way. If you can't make your case for funding to the masses, they're going to ignore you; once that happens, the politicians will smell money, and move in for the kill.

    Politics is circus. And thus, anything that derives its funding from the political process, or has to otherwise interact with it, needs to get with the program.

    Unless you have some brilliant ideas on how to make NASA totally self-funding, it's the "PR stunt" missions that are going to effectively pay for all the boring research ones, that Mr. and Mrs. America don't care about.

    Too bad there aren't enough 'actual scientists' to have much of a vote. That's the pain in the ass of a democracy: it's not just the smart people who get to have a say in running things. If you can't convince the non-scientists of why you need money, you're not going to get it.

    The irrational feelings of the masses affect science all the time. Look at stem-cell research; that's a whole field that's basically turned into a proxy battleground for anti-abortion groups. I think a lot of researchers there tried to just stay out of the mud-slinging, but in doing so they basically got run over: it wasn't until after the religious groups got their laws passed that any of the research organizations started doing their own PR. If they had been doing good PR work from the beginning, it might have never become a national issue.

    Science doesn't exist in a vacuum. It's not something that can just happen on some high academic plane, removed from the ugly realities of the political process. If you want money, you need to make average people -- people, in many cases, with a high school education and a crappy one at that -- understand or at least feel connected to what you're doing. And you need to do it constantly: not just when you've got a problem and need public support. You need to bring the public along from Day 1. I hope that these asteroid missions are NASA finally waking up and realizing that you can't ignore the public on one hand, and expect them to pay for your research on the other. It doesn't work that way.
