This is a bit more difficult to respond to. Even the testing and further developments of the electronics including sensing, and control, and such is not...
As an addendum to research on composite materials, and with relevance to previous discussions, I include this link on the science undertaken by NASA in this...
Jan, Talking about "learning to work within the rules of the space environment, rather than traditional precedents from Earth", here's a short reminder: You...
We could process outer space dust and other materials, but carbonyls and especially iron is so easy to use. Mostly I want to say the for optical telescopes...
OK. Ueli, the problem here is having a thousand thoughts and only explaining one! Yes, have taken on board the merits of the carbonyl process, which would seem...
Jan, Yes, we covered this earlier, but good to reassess: All processing of asteroid material should take place in Earth orbit, for exactly the logistical...
I agree, more than one method is better than just one. No need to discount everything else because we have one avenue. It depends a lot on what we are making...
Hi all, I'd like to get a handle on some construction implications for shielding against junk/meteorites and radiation. I think we need to sort this out...
It sounds quite reasonable to me. Light, successive screens with plastic pellets would be bulky, but there's no need for streamlining in space. Ultimately,...
Hi Dennis, "Some kind of force field?" What do you mean by that? A magnetic field to protect a spaceship from solar radiation? That idea has been bounced...
This is the first I have heard of this refraction method. This is most intriguing. The 10 blankets sounds like a good model. The chainmail concept also...
Was thinking of more than LEO, and a more maneuverable "capsule" which could hopefully detect and avoid "incoming" rocks. I have heard that someone is working...
Debi-Lee, Good point about our station going in the same direction around Earth like most other junk, so maybe less of a headache for collision velocities.... ...
Jan, is there any way we could get a graph on how a shield jacket of many layers of "chickenwire with threaded plastic beads" could look like? Something like a...
Ueli, in the research links I recently posted, there was an article outlining that even parallel flying junk is hazardous. The ISS had to elevate itself with...
Ueli, Well........threaded beads have many problems. One needs multiple densities of the spheres to create the radiation shielding effect, and they would need...
Ooooh Jan, damn good point! Don't want spillt grit flying all over the place do we? Oh no we don't. That would be a major disaster. Hm... okay, you're right,...
Jan, I like the idea of cheese graters as an alternative to the chicken wire. Mainly because I believe rolls of metal sheeting can be more densely packed for...
Ueli, Yes, I think we are still on the right tracks in thinking layered braking. The ISS has had to make do and mend literally on the fly, where in fact we are...
... You got it. ... You were talking about making a layered system. So I was suggesting that the outer layers handle the slower stuff of which I expect the...
Would the plastic beads have a tendency to melt on impact by a speeding bullet? Or can we design them to be? This could then be self sealing if they can be...
Debi-Lee, Yeah, flux of junk. Turns out this apparently was hugely underestimated for the ISS, particularly on the very small stuff, resulting in something we...
Plastic beads would indeed melt when slammed by an incoming piece of junk. And I think Jan had the idea that this would help in self-sealing. There is another...
Jan, "We just have to tease out the different layer functions at different levels of the concentricity, optimise the nature of the materials employed, and what...
Hi all, I gradually see a structure evolving for the milestone on shielding. 1. Make an overview of why we need shielding, and that we concentrate on shielding...
When material heats up to the melts pint in a vacuum it tends to vaporize instead of melting. In a full vacuum you have solids. In a container the vapors build...
Yes, that list sounds practical, Ueli. The chain mail is an interesting thought, as thinking of it on a trawl-net scale formed of straight links with eyed...
Going back a bit, Ueli, I have been re-reading the literature on asteroid composition again, and considering the proportional balance between rocky, icy and...
Jan, Great, some new angles here.... A. Concrete and ceramics as elements of refractionary shields. B. Heat shields from space as an early source of income. C....
