ok so this helium-3 is it in ice form on the dark side? or do they have to bring lots of gear to extract it from the dust? Either way it's logistics night mare.



You're more-or-less correct.  H3 is in the soil.   Extracting it is problematic at this time, of course.  About 28 million pounds of lunar soil would be needed to extract 1 pound of H3 by heating it to high temperature and extracting the gas (with oxygen and water as by products, which is also pretty nice).

It's a great idea for a very safe, high energy fuel, but that's a ways off in the future, I'd say!

28 million pounds ?

how did you arrive at that figure ?

im all for returning to the moon

Thanks for asking that question.  
I made a typo.

I meant to say 1 TON of H3 can be derived from approximately 28 million pounds of lunar soil.  It's amazing how one little word can make you about 99.95% wrong!

But anyway, this figure is a reduction of an obscure ratio based upon the amount of helium 3 found in lunar soil samples, and some research put out by Jack Scmidtt, Apollo 17 LM pilot and researcher on the topic  (others have done some in-depth analysis of this problem as well).

About 25 tons of H3 could supply U.S. energy needs for a year, in very safe fashion.  But that would take about 350,000 tons of lunar soil to produce.   It's a daunting project to contemplate, and is quite a ways off in the future.

But returning to the moon would be essential to even start serious development.

I'm all for it too, and have been since December 1972, when Apollo ended prematurely.

Regards.

Helium 3, one of the universe most abundant element. The crap of stars, not to mention that we have no functional fusion powered plant yet. A better and cheaper way for harvesting Helium-3 would be by constructing a giant helium 3 collector made of aerogel/palladium particulates and orbitting it around earth, palladium molecules will "capture" He-3 we crack it and process it on Earth, aerogel, because its very porous and hopefully will capture some He3 as well. Have no idea which is more efficacious, so both method should be used. He3 will still be one of the most expensive molecules in the world.

so it would take 14000 tons of moon rock to get 1 ton of HE-3

is it worth it ?

We need to go back, yes.  Our planet can't possibly sustain the human race for much longer.  I predict we'll eventually have entire cities on the moon, similar to Granada and Von Braun City as mentioned in GUNDAM.

But of course, that's a long way off.  If we could harvest Helium-3 from the moon and harness fusion energy, though, we'd have an incredible boost in the range of our space program.

A short rest stop?

The moon would only be a couple days out from earth?  Why a short stop there, when the rest of the journey would be months long?  

No, I think rather that lunar obit would be a reasonable place to actually embark on a Mars mission.   The vehicle could be assembled in Earth orbit, flown out to lunar orbit on a final shakedown, and "launched" as-it-were, from lunar orbit toward mars.


...of course, THAT is a ways off!  We've got to get back to the moon first.

well i was talking way in the future

people would go to the Moon Lunar Hilton for a couple days en route to thier Mars vacation

the earth can support the human race forever as long as we stop with so much un-biodegradable waste and  the high consumption of oil.

there is enough oil on this planet to last many many more years

just tap Alaska

but i cant wait to be able to see moon landings in my lifetime

i was born in 71
