Well, this time I was obviously not clear. You're right in saying that we have to bring everything we can to the station, as even the worthlessmost rubble is...
Hi Romuald, of course what you say makes sense, and while we are endeavouring to build a comprehensive picture of the integrated infrastructure necessary in...
Romuald, Ah.... some hard-nosed commercial thinking. You are entirely right. I love it. And yet, we're not at a stage where we can sort out the real clients...
Let me rephrase, to see if I understand well. 1)we go to asteroid, explore, mine, & bring back a big pack of "stuff" 1b) at the same time, we set up an...
Romuald, PGM means: Platinum Group Metals. The CVMR process allows to separate out various metals in high purity. Most asteroid metal will be iron, followed by...
Romuald Jup, I think you got the sequence right, except the PGM ingots we drop to Earth and sell them there, not in orbit. You wrote: "2b) Mr sattelite & Ms...
Yes, makes sense. I'll still try to find how hard it is to store water in zero-G, & to transfer it from the extractor to the standard "fuel" cell. For the...
Water is not very hard to store. To move it from one tank to another is more difficult. The liquids need to be separated from gasses and settled to the...
A big question is do we first cook out water at the asteroid or LEO. If we wait for LEO then we need to start with more water lifted up from Earth. Â The fuel...
Having the station Depot and Tug makes sending stuff the asteroids much cheaper. We only need to send up the LEO processing equipment just before the material...
Hi all, I managed FINALLY to get it all together and upload our milestone on shielding. Thanks to Jan for the final tweaking of the PDF file. So it's there to...
Jim, ... If we wait for LEO then we need to start with more water lifted up from Earth. ===> Yes, a tradeoff that is so typical of all this space stuff. My ...
Hi all, I just reconsidered the earlier "Water from NEAs at LEO". See below. Raw NEA material at LEO ========================= Automated miners at the NEA dig...
Ueli, how far does the production of water at NEA source, affect the economics of carrying fuel only for the outward journey from LEO ie: self-fuelling the...
Ueli, further thoughts: Initially, we considered that in the design of the NEAminer, that the microwave fracturing of regolith would release volatiles under...
Jan, now that's a damn good question. Let me try and put it more succinctly by comparing various options: Option 1: Take water with us for return journey Tug...
Jan, You wrote: "Initially, we considered that in the design of the NEAminer, that the microwave fracturing of regolith would release volatiles under the ...
Ueli, this is where we have to get careful with the design details! ... There is a flexible 'skirt' or valance at the point of contact of the main NEAminer...
I think Jims concern was a different one: It looks like most NEAs aren't solid through in any way, but rather 40% "hollow". That means our borehead won't be...
OK, I am mining the logic to the end here, Ueli............. If heated and steaming gases percolate from the superheated drill head area, the same scenario is...
Hi all, another situation which I find is critical in very early stages. What do you think of this? Tugs operating in LEO ... A LEO tug operates like this: a....
And another one...! Interplanetary tugs operating ... Interplanetary tugs differ from tugs in LEO in that they escape Earths gravity well with their cargo to...
I think what you are describing here, Ueli, is the 'transporter' rather than a tug? This is what I was referring to in this post: "Additional to your points...
Jan, Lot's to think about here. (I've checked through your figures. If your entry data is correct, I get the same results): 1. First of all the Nantan...
Okay Jan, Just had a look through all your great graphs on the freighters. What I like in your versions 2 is that we're obviously getting into a "modular"...
Right, Ueli, the Transporter 2.0 images are still incomplete, although slightly more advanced than those previously posted. Nevertheless, I thought they added...
Thanks for checking those figures, Ueli, the starting data is referred as listed in the links, and the volumetric calcs come from some online physics...
