Hi(gh)!

With an unmanned probe carefully braking to adjust its speed to the 
particles (which are in fact just tiny "moonlets" following Kepler's 
orbital laws), such a photo should be feasible - small particles 
diverted by collisions should not move faster than a few meters per 
second relative to the probe and thus pose no risk, bigger ones could be 
dodged automatically.

And then perhaps even do a sample return! Has anyone at NASA ever 
proposed such a mission?

And for the occasional star peeking though the media: feel free to use 
my customizable sky_sphere!

Nice. And so very relaxing when all the work does itself.
I highly recommend posting code snippets at Thomas :)

Regarding the isosurface function I still haven't fully figured
out how to apply a fine pattern to a coarse pattern (such as granite
structure on the crackle particles) without also generating "granite
fuzz particles". This is related to why you didn't get ring structure
on the fuzz. There is probably some smart way using min / max / select
but the things I tried didn't work as expected.

For the time being this is just a prop.

Yes indeed! I seem to be unable to restrain myself. You are deeply 
thanked for the snippets though. Keep them coming! ;-)

I have not delved really seriously into it either as I was concerned 
with other issues that need ironing out. I shall though.

I would not be surprised if they had some blueprints in a closet.

I must say that in my image there (still) is some artistic freedom in 
the fact that the ring particles are (much) larger than in reality.

When I come to that, I will use it. Thanks!

I just learned he failed about every test at the Space Academy of Mercury...

Yes. I keep that in mind for later. Isosurface and media need a much 
higher quality indeed but this is faster ;-)

Still looking for improvements. This is the closest I could get 
presently on a small scale (see image). On a large ring scale, it does 
not look good/convincing at all.

Using the following code:

#declare f_particles =
function(x,y,z) {
   0.5 - f_crackle(40*x, 40*y, 40*z)
   + f_granite(x*0.1, y*0.1, z*0.1)
   - f_onion(x*10, 0, z*10)
}

isosurface {
   function { f_particles(x,y,z) }
   contained_by {
     box {<-0.50, -0.5, -0.5>, <0.5, 0.2, 0.5>}
   }

   accuracy 0.0001
   max_gradient 1000
   texture {
     pigment {srgb <0.98, 0.98, 0.98>}
   }
   translate 0.25*y
}

But this has better potential (see image) using as function:

function(x,y,z) {
     0.8
   - f_crackle(400*x, 400*y, 400*z)
   + f_bozo(x*100, y*100, z*100)
   - f_waves(x*100, y*10, z*100)
}

nice. you can also add some turbulence by adding a noise term
to the input parameters of the functions, e.g.

   f_waves(x*100 + f_bozo(x*100,0,0),
           y*10  + f_bozo(0,y*10,0),
           z*100 + f_bozo(0,0,z*100))

(offline sample, scaling likely way off)

I like this. the method which combines two functions looks useful.

It seems there are a lot of techniques on building functions.
