    It seems spacecraft-based magnetospheres will be the likeliest way to combat this:

  2. Tonight the inky black is cut with pin point whites up there, n white noise crickets’ n surreal lamp posts leaning their shadows over the neon. Some croaky far off is lost, sending sounds hollowing; deepness n silence are hard stands that dogs pass thru while other things go on in places of abandon. This is the way of it here: flitting lizards n fast growing things, a swamp of luscious; it’s a knowing not a meaning, a oneness with all that is a night of it all; a never knowing what may happen but it could; but it is all out there, someplace beyond and yet here too..this is not made in a factory, rubber stamped, this is a far growing thing in the now, that grows with every moment, becomes what it is…I look for the empty space that surrounds, for that one thing I look for…bell sounds again from the temple some time only they know, as if to say this is the time you all must know and we are ringing it to you, for you, and we are here to remind you that we are here. The crickets talk to each other and know their time is now, the only time there is, a song that can be felt, ever changing, yet ever the same. Stuff on the borders of mind intrude with calls of, ahh, whatever they call; things slow in the fast of it as the fast of it cannot slow but the here of it just is. It is a thing, in a thing, with a breeze in a tune that reminds of something that cannot be known or forgotten or remembered. Dust of the lion, the tiger, the wolf; eye of the eagle, the shaman; the angel feather that floats into your hand in the wind that is impossible in that field that is only in your spirit that calls but cannot be answered for its purpose is done and is now only a memory, yet is a feast to be lost; so make a garden of delight to have a bar-b-q and invite friends around to share your forgettings and gettings because you know the big black inky will out-live you in the huge happenstance of your life. This is a miracle with a bone that reaches into you to be answered all that you are, take it or leave it, your now is now.

      Some people are hit in the face by space radiation and see nothing but little flashes inside their eyes.
      Put this man in space.

    How space radiation helps astronauts:

    The NCRP has been on this from the beginning. See their various publications for purchase at

    And see Slate for a simple review of this paper

  5. Boundegar says:

    Radiation is bad, yet Congress stubbornly refuses to outlaw it.  Obviously they are in the pay of the photon industry.

  6. Wesley Coll says:

    We need good guys with radiation guns in every spacecraft, so they can fight foreign radiation from space on equal terms. It’s the right of every astronaut to be protected from this scourge of the universe, obviously bent on destroying the American way in space.

    • fuzzyfuzzyfungus says:

      Thanks to destructive interference you could theoretically neutralize gamma radiation with an emitter tuned such that its output is of identical amplitude and frequency 180 degrees out of phase with the incoming radiation.

      Construction of a gamma source that achieves these requirements in response to real-world radiation sources, and for the protection of useful volumes of spacecraft, is left as an exercise for the reader…

      • B E Pratt says:

         If I recall correctly “…is left as an exercise for the reader…” is called ‘hand waving’ in mathematics. Particularly useful if you don’t want to spend the entire semester dealing with, oh, say, Green’s Theorem.

        • fuzzyfuzzyfungus says:

          That was definitely my implication here. Even for fairly trivial 2-D cases with ideal point emitters, actually getting destructive interference to work as advertised isn’t easy.

          For a 3D case, with multiple media having different optical properties and rather unpredictable input, Not Pretty. Hence the reader’s problem!

  7. Wesley Coll says:

    Either that or a spacecraft wrapped up by a big bubble full of water or other liquid, I’ve read. 
    By the way, Mr. Moriarty above (or below) seems to be a bit lost in this space, yes?

  8. fuzzyfuzzyfungus says:

    It would be interesting if team fertility medicine(along with our trusty robots) ends up being the most viable solution:

    If you were able to grow fetuses in Brave New World style tubes, you could ship enough frozen embryos to provide a substantial, genetically viable, population at your destination in a fairly small cryo tube. Cuts down on the amount of volume you need to shield considerably.

    The only awkward bit would be finding some sacrificial first-gen humans to take the job of raising batch #1 of vat babies(since tending baby primates entirely with robots probably won’t produce a bunch of psych masterpieces) and then dying relatively early from radiation damage…

    I don’t think that NASA should worried about space radiation. Because they had send people in rubber suits at the Moon, remember? And nothing happened.  So if they will continuing  same way  all will be the best ;)

  10. HZE: High Charge and Energy. (Herzegovina Emunclaw: Phew!)
    Watch, it’ll all be triclosan and ‘imprinted’ water once we get instruments suitable for telling us quickly what we got hit by ca. the speed of light (well, those can’t take a charge like that, so imprinted aluminum and silicon ions and big garbage nuclei.)
      Obvious outcomes would be a shield that reads the ion fine structure, reflects it more nicely than a heavy bosonic condensate (nobody wants the impulse velocity,) and takes the data to read and be disgusted by; attracting the charges ahead and off the path and studying their play there; let the radioactive waste absorb the particles, reducing them to a previously solved material management case.
      So they turn out to be full of ads for alien races’ Erowid rejects and improper payments, all sent from other quadrants of space to throw off suspicion; Chthulu just forgot to remove his out-of-office autoresponder, so it is personally addressed to Rae-Lyn Shoggoth, Phan Kui Lyn Shoggoth, etc.

    Space dementia has been part of NASA folklore (common knowledge?) for decades.

    unfortunately my first attempts to reproduce Star Trek’s ‘Hyronalin’ essentially involve drinking a measure of lead paint.
    Early trials have been a mixed bag of results; test subjects certainly don’t suffer from any further debilitating symptoms of radiation poisoning.

    Hum. The image of Legos thrown down a stair well. Reminds me of one of my favorite Journal of Irreproducible Results articles wherein the author describes how to grade papers (term, essay or anything requiring bulk) by taking them and tossing them in a stairwell. You should get a bell curve with the weightier papers on one end (the A’s). Simple and effective (assuming you don’t really give a damn).
