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...

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...
If I did not care so much I would have left this blog long ago. I am sure some of our not well thought out parts have driven off many of the educated...
Jim, Thanks a lot for your points. We'll talk about them and take them up in the next version of the paper. I do hear a kind of frustration from your mail...

More input to the gravity gradient boom specifications includes this posted file: Files > LEOstation Reflector_Description.1.pdf 'Gravity gradient boom...
The only way the boom can stabilize the direction is because one end is in a lower orbit where it would need to be going faster and pulls down. The other end...
Easy Jim, let's not throw around with expertise. You wrote: “Almost anyone who understands orbital mechanics well will laugh at the extra danger, waste of...
Yes, reopen a can of worms and we can continue for ever, Ueli! Just a few points (which were in my posts)........ -- we need evidence to support speculations...
Hi all, Went jogging today and got this brainwave. Wonder where it will go.... So we've got a first milestone on the LEOstation. But it looks to me that that...
Maybe the Bigelow IS the garage, Ueli? Albeit customised to our specs, but seems to be it will be the same kind of structure, inflatable and well-kevlared. ...
Yeah Jan, I've been thinking of Bigelow hotels. They will have a role to play, by all means. I do believe much of the station may be built with a Bigelow as a...
