[Space Research] Micro-G Arachnid Habits

[Kreij]

Snakes on a Plane? No ... Even better. Spiders in space.

New International Space Station Tests on arachnid habits (like web spinning) in micro-gravitational environments.

IMO, this is a worthy experiment given the strength of spider web strands (per units of volume) and what the structural makeup of the strands is like in near zero-G.

Cool stuff. I'll be watching for results on this one (if they ever publish them).

Okay I fixed the link and removed the posts.

The reason I posted this thread is to get scientific speculation.

Let's say that the spider's web threads are 100 (or more) times denser due to the near zero-G environment.
This could mean that a fabric woven out of the threads could make Kevlar look like tissue paper.
It could mean a huge increase in weight bearing strength of a braided rope made from it.
The adhesive quality of spider webing is already legenday (at least to flies), could that be a new derived type of super adhesive?

Your thoughts?

I have dreamed of this since I was a child. Seriously.

I wonder what happened to the spidergoats.

I don't know, Frick. I read that too when it first came out and thought it was very interesting.
Perhaps you have to inject the DNA into kids and let them grow to see the results (which would account for a timed process).

If you can produce amazing things in zero-G, perhaps the goats can just go back to being regular old goats. That would be superior than altering the genetic makeup of a species.

Of course, even if nothing pans out, there is ample opportunity for a cheesy original SyFy movie.

but still its not economical to harvest it yet.

I think the best way is to alter silk worm dna so it will produce spider web type of silk.

Uhm, already done in 1973 with Skylab 3. Some article

 

[Kreij]

Yeah, but back in '73 everyone was smoking pot and had the munchies and were more interested in oreo cookies than space spiders.

On topic ... Advances in our ability to analyze the results may show things previously not noticed.
Or not.

It's milking the spiders that's difficult.....hence the goat. Might as well make SpiderBovines.

I think they have the chemical structure of drag line silk (the strongest) down. IIRC, it alternates between a very strong fiber and one that has a helix-like spring structure. That's how it can be both strong and flexible.

I think the problem with putting silk genes into other animals is that spiders have a special organ where the different chemicals for each kind of silk are mixed. I think that is the main problem as opposed to finding a way to manufacture those chemicals.

What we really need for things like body armor is a molecule that contracts when stressed so that if it's hit, all of the molecules in the area come together at the point of impact and create an opposing force. I think I read about something like this but I probably wouldn't be able to find it again. Something like that would not only make for stronger lighter armor, but would reduce the trauma you get when hit by a bullet. Even if it doesn't go through the vest, you'll still be hurtin' afterwards.
