Joe, Phew, we nearly lost you!! Glad you tried to get back in. Okay, so I've uploaded your new address on all the Yahoogroups you were on (plus discovered that...
Hi Ueli, I trust that you are having an interesting time in Portugal. Have you come across any new landscapes, or terrain, that reminds you of Mars? Having to...
From James Wilson spacetrader.net/ b2b-galaxy.com Something we need to keep in mind, on asteroids, the rubble pile aspect with boulders moving around due to...

Hi Jim, Good to hear from you. I think the problem of mass of boulders in a loosely floating blob of rubble isn't too hard. First of all the boulders will not...

Hi all, I'm again sending the below message which I had sent on May 10th. The reason is because it lists the competencies required to achieve NEAmining, and...
I have a few issues. They could be compartmentalized, but they need to be looked at together. Many of the problems overlap in a few areas. Being solid metal to...
Making the "ferries" to navigate in the asteroid space creates new problems. Going into free flight means attitude jets are needed with much more equipment to...
The initial asteroid habitat should start similar to the Mars Transfer vehicle. We need to keep the people health on the way there. Then we need to protect...
Dr. Robert Silva's work indicates that the near 0.4 G gravity of Mars is probably not enough gravity for good human health. We need a way to test for this. Jim...
Hi Jim, good to see you here. Thanks for separating your posts into various topics. That makes it easier to respond. So here we talk habitat. We haven't yet ...
Jim, Thanks for your comments. You make quite a lot of commenting on the asteroid composition and physical structures and their history. We have covered that ...
Hi all, The more I think about bootstrapping the process to commercially successful NEA mining, the more I come to realize the importance of knowing how to...
One reason we did better on the moon is we learned how to deal with lumpy gravity wells. Even just conservation of energy shows even with a lumpy gravity field...
I am sure Itokawa is not a typical carbonaceous contrite. It has been partially heated. It will be hard to mine. The harness spreading the load over the entire...
Hi Jim, Most importantly: What makes you think Itokawa isn't a typical chondrite? Calculations show it is around 40% porous, ie. 40% of its volume is just...
Jim, ... field we will go back through the same point and vector if the orbit is a multiple of the spin. Correct. But that is a big IF. ... reasonable...

Dmitri, Wow! 20% Iron and enough nickle to measure. That is great! I know you can't deposit it on anything more than a slide but that's okay if you didn't....
Good to hear that Jim is raising issues that help to hone Occam's Razor. We should keep worrying at things until something breaks. Better here than in a...
Wheee Jan, swarms of microtugs in LEO... Namba Wan Big Fun!! But first need to learn to operate at least one successfully, don't we!! How would that first ...

We pick the orbit so finding a harmonics of the orbit and asteroid spin should not be an issue. There are two counter balances that we need. One is way past...

..........then Ueli, we look at how the breakup of space debris is distributed in a volume of space, in order to determine the shape of the technology to...
Dear all, Okay, so on the "General-Discuss" mailing list of Marshome we have told everybody that the "Rig for Mining" is now accessible on the website, along...
Okay all, we need to reorganize a bit or else we will be shooting off in all directions and not get to nail down some progress. So let us list the topics that ...
Thanks Juergen, good to hear from you. Here's my take, though I will of course also be moderating if need be on any of the others where three people...
In the next few months I want to work on the following topics: ( X) Rig for Mining ( X) LEO-tugs ( ) Bootstrapping habitats ( ) Argumentation for industrial...
