NIAC Selects 2005 Phase I Winners

Pooua writes "The NASA Institute for Advanced Concepts (NIAC) has selected its 2005 Phase 1 awards winners. Two of my favorite winners from this year are 'Extraction of Antiparticles Concentrated in Planetary Magnetic Fields' and 'A Deep Field Infrared Observatory Near the Lunar Pole.' A brief summary of the awards is available at Spacedaily. The NIAC Website lists links to PDF articles of all their funded studies (past and current). Slashdot covered NAIC awards winners last year."

Website lockin! Yay!

[Dancin_Santa]

Anyone have a link that doesn't try to pop up fastclick crap and also try to lock you in by auto-forwarding you a few levels in?

That said, I thought Artificial Neural Membrane Flapping Wing was pretty interesting. Penguins are looking forward to the possibility of finally putting those puffins in their place.

Antimatter: the next exploitable resource?

This is quite an interesting proposal. Of course, 10 micrograms of antiprotons is still a tiny amount. I ran across this web site that talks about antimatter as a propulsion mechanism. That would probably get a robotic probe someplace pretty quick. Still, how quickly does this resource replenish itself? Every year? Every century? Hopefully it won't be like our oil reserves.

Of course, as the article points out, you could always send robotic miners to the Jovian moons. Antimatter is probably the most valuable substance by weight in the solar system.

For those who don't want to open up the PDF, here's the abstract for the antimatter recovery scheme:

Small quantities of antimatter (nanograms to micograms) have enormous potential in a variety of space, medical, and sensing applications. However, due to the high intrinsic cost of production, such applications have not yet been realized. Antiprotons are currently produced during high energy collisions in large particle accelerators. Based on current capabilities, the electricity cost alone for the process is estimated to be $160 trillion per gram collected. In comparison, high energy cosmic rays bombard the Earth's upper atmosphere and produce the antiprotons naturally through pair production. A fraction of these are subsequently concentrated within the Van Allen radiation belts of the Earth similar to their standard matter counterparts. Satellite and high altitude balloon measurements have confirmed the fractional existences of antimatter in the normal background of ionizing radiation. As particles are lost through diffusion processes, new ones are generated to maintain a quasi-static supply trapped in the near dipole field of the Earth. Based on preliminary calculations, it is estimated that 10 micrograms of antiprotons and 10 milligrams of positrons are locally contained within the Earth's magnetosphere at any given time. The Jovian planets with their strong magnetic fields are expected to contain significantly more within their radiation belts. Draper Laboratory and its collaborators propose to use a magnetic scoop to extract large quantities of these trapped antiparticles. The principles of a Bussard magnetic scoop, first proposed for relativistic propulsion, will be adapted for use on a satellite in a planetary orbit. Particles bouncing between mirror points near the planet's poles will pass through and be concentrated by the superimposed magnetic field. Separation and cooling techniques from particle accelerators will be adapted for extracting and separating the desired particles from the radiation flux near the satellite.

notice who's in charge...

The P.I. for the "Deep Field Infrared Observatory Near the Lunar Pole" is... Roger Angel. No, not the baseball writer, the two-ell angel, but the astronomer and telescope designer from the U of A who pioneered using spun-molten-glass as a means of making huge, thin mirrors.

Here's a story from Universe Today and one from space.com.
