Folks, would it be smarter to do the processing in LEO? While jogging up along the river here, Jan's graphical rendering of the digger-concept bounced around...
All, Hm, any tradeoffs between this processing at LEO with the earlier operational concept where we were processing the asteroidal stuff into volatiles, metal ...
Well, I'm on a roll.... Two things turned up that might help us fund the space infrastructure: a) Tugs for space junk ... We certainly need tugs for our NEA...
Ueli, ... A draft schematic is posted in 'PROCESSOR FILES' of an asteroid orbiting processing plant. In this version it is envisioned that it is manned, at...
Could anybody clarify the orbital relationship between a processing station, or other off-surface elements, and a host asteroid? It seems to me that the local...

Thanks Martha for chipping in and challenging the wisdom of my crazy ideas. ... Well, I was realizing, that we'd be bringing all the volatiles and all the...
Hi, a line in this message reminds me of a suggestion I floated out somewhere months ago, and it disappeared in the noise. The context then was that hydrogen...

Martha, Water will be one of the most important things we mine. You get the gist on the water-rocket. However, instead of putting water into the focal point of...
Hi, Ueli. You misunderstood what I said. With a bottle rocket full of steam at 2000 F, you don't need to expend it all in one throw. Given good design, it...

Well Martha, whatever..... It's clear that we will need propulsion that is cheap and easy. And quite obviously it seems to me the fuel will be water, not any...
Hi Jacob, Oh man, you're reminding me! We once had this idea of producing regular newsletters on where we are etc. And the last one was status 1. January. I...
Jan, Yeah, I've been wondering about orbital maneouvering around NEAs too. I'm nowhere near having the maths at my fingertips to do any calcs, but I've given...

Thanks Debi-Lee, So MET-engines it is. I wasn't aware METs heat to the point where the water molecules begin to break apart. So they contribute the bang of...

Debi-Lee, Yes, I was aware of the Orbital Transfer Vehicle OVT, but was puzzled why it hadn't yet been explored with a MET-drive (Microwave Electro Thermal, we...

Hi all, I find this pointer in AdAstra Online Magazine (see below) an interesting new angle on the Mars effort that we can either ignore and thereby possibly...

Ueli, The ironic thing is that what you are describing in the Orbit Transfer Vehicle/Tug scenario is a formulation that is 1) better defined than NEAmines, 2)...
Yes Debi-Lee, I think you are right: We're much clearer on the tug, than we are on any other piece of equipment we'd need for asteroid mining. And I'm not...
I am convinced we will need humans on the asteroid to setup and adjust, adapt, upgrade, troubleshoot, and repair. Much of what we are doing will function...
