We do know how to make a cable that is secure and not harmed from debris or orbital junk hits. Mostly it is more like a widely spaced net. No single hits of a...
I printed out and was going through the proposal. After writing lots of comments on the paper I lost it. This is what I can quickly do, but reserve the right...
Hi Jim, I'm back more or less online after moving around on travel for three weeks.... So, thanks for all your thoughts on Alpha Station (we'll call it...
With the anchor just one direction there is a lopsided pull. The mass below center of gravity is going slower than needed for stable orbit and pulls down. The...
Hi----- I include this for the record, as it contains extra information that I have sat down and worked out for the functioning of the NEOminer, using...
Great Jan, Just read through this, and .... well, great for these students. Should get them to thinking about this. While reading I again thought how...
Well, not entirely speculative, Ueli, I have worked to the minimal rate of excavation I thought practicable after calculating the cylinder volumes and cut...
Jan, Okay, I think I get you. And yet my concerns remain. We don't know what the cutter with the microwave shatterer will be facing: - hard "rock" onto which...
Ueli, As always this feedback helps to clarify the subconscious graspings at an idea. What I remember thinking was that with low gravity agglomerations, there...
Ueli, additions to the bibliography: http://www.ingentaconnect.com/content/maney/mint/ 2006/00000115/00000001/art00004;jsessionid=pqic6egkjk49.alice? ...
Ueli, For your interest, I am working up a polar mining concept at the moment, which has devolved backwards from the end user domains previously visualised....
From James Wilson spacetrader.net Concept idea: Mars has a high sulphur content in its regolith, wouldn't that mean that the subsurface ice could be solid or...

From James Wilson spacetrader.net I have a Canyon Diablo meteorite----- which I think was an asteroid, that hit at meteor crater in Arizona. Looking at it...

Hi James, I'm sure Joe Palaia (that's the way he spells his name) would be delighted. Joe is on this NEAmines group too, so he should have gotten your message...
Hi James, I guess this posting would be better placed in Marshome.org? Are you a member there? On NEAmines we're concentrating on developing the asteroid...
As I look at this Digest #402, I feel provoked to a couple of comments about its content. Re the electric drilling scheme from gems@..., it looks weak to...

Does anyone know where I can find a Portable Core Drilling and Sampling Machine? Klinton ... From: Martha Adams <mhada@...> To: No Reply...
Martha, Good to hear from you... ... Yes, radiation is going to be a killer unless we get smart. And yes, we've already been thinking about digging down into...
Not really wishing to dig over old ground, Ueli, but I have previously posted a fair amount about cavity walled polyethylene spheres. A material rich in...
Yes Jan, I had those small PE-balls in mind too for shielding ships, and the reinforced concrete constructions for space stations. I was just clearly defining...
Hi Klinton, if you are based in the USA, you might find this source a useful supplier of portable rigs for drilling and coring: http://www.hydra-jett.com/ ...
Refractive shielding is definitely in mind, Ueli, and is a principle that is fundamentally correct. If my understanding is also correct, by varying the...
Yes it could be better to have the magnetic bearings with a large diameter, but the docking caller, shuttle, and such or the magnetic fluid seal should be...
Thanks Jim, All right: The boom is a laced construction. Kind of looks very similar to what we thought as grided. Not much difference between "knitted" laced...
Hi all, Jan and myself are putting the final touches to the LEOstation milestone. While we grope around for the next milestone, I've sent the below out on...
Okay everybody, at long last we have the first milestone on the LEO station. It's too big to be sent via Yahoo (a pdf file of 3.6 MB). But you can download it...
Sure Frank, great idea. Go for it! This stuff is public domain already, since we've published it on a publicly accessible website. Will be interesting whether...
Global mapping of the degree of space weathering on asteroid 25143 Itokawa by Hayabusa/AMICA observations Authors: Ishiguro, Masateru; Hiroi, Takahiro; Tholen,...
Ueli, Have finally had time to think out a response for the New Scientist competition "Visions of the Future". This can be found under my heading 'A Foothold...
