I like what the RAND puts out as well. In most cases you can download their PDFs for free.

Sorry there was an error with the AGU, here is that link to their site.

Here is another geological / planetary site and it is a winner.

American Geological Institute.

“To accomplish Dawn’s journey into the heart of the asteroid belt, a space ship, one whose engine will work without fail for years at a time, is required. Dawn’s remarkable ion engines employ electrical currents, magnetic fields and xenon. The high tech innards of an ion engine change the xenon into a positively-charged plasma and accelerate it out the engine at speeds over 78-thousand miles per hour,” said Nimoy.

“A mission into our distant past, a mission for the future, a mission into the heart of the asteroid belt, a mission called Dawn.”

Here's a you tube video on it:

And you know what?

THIS IS ANOTHER TECHNOLOGY STAR TREK PREDICTED!

Captain Ransom used this technology in Voyager.

Sorry for the shouting, but I just love it when I see Star Trek predict and inspire technology.

That's one of the things that science fiction is eggsellent at.

Get's me all hot and bothered.

Yep… the beta-emitter is particularly nice in a way … except that its also likely to cause neutralization of the very ion stream that we're trying to deflect. This is not to say that having a big fat, concentrated beta emitter at the center isn't a good solution! In fact, it needs only be open at one end (the forward end!) in order to do its job. The betas going backward could be intercepted by phosphors and provide substantial electricity. You know, "betavoltaic" 2 birds, one stone.

(hmmm… thinking)

Beta sources are actually pains in the patood: essentially they are only surface emitters. Get a block of the stuff, and all those cute lil' electrons get caught by the material, and never escape. Maybe this isn't a bug, but a feature! Creating betavoltaic panels, PV cells on the sun-side pointing both at the sun (why not?) and on the other side, away from it, but coated with phosphor, the beta emitter, thick enough to be both an optical reflector (redirecting the phosphor-light toward the PV cells) and emitting electrons furiously in the wrong direction (but right to create a positive-charged space ship)…

Wow. What a concept. Kind of a nuclear-powered space vehicle.

Actually, one could also just collect the wrong-way electrons too. We've discussed this before: when a sufficiently negative (hundreds of kV) potential exists between a beta-emitter and a collection plate, the betas are decelerated efficiently, and slam into the plate at much lower kinetic energy (voltage). In so doing, they're efficiently transformed from high energy particles to lower energy, while bolstering the high e-field. Tapped away through high-voltage switching, and then transformers, they easily can be converted at high efficiency to a torrent of much lower voltage, much more copious electron flow … suitable for the spacecraft's electrical system.

Another nuclear win.
