Your floor is very reflective. It makes the protons barely visible, if at all. 
Try rendering again but without photons and see if there is a notable 
difference. Rename your current image to preserve it and make it easier to compare.

Well, not if you're a rocket scientist ;)  I was going for a tabletop
display look, so I made it an indoor scene.  Any other ideas for the
surrounding?  I'm open to suggestions...

You're right, I'm thinking about changing the tabletop surface.  Here's
another render, and you can see a slight effect in the shadow of the rocket
(near Earth's reflection).  I like the effect, and if I change the surface I
think it will be more visible.

That statement is so silly it's not even worth responding to.  But I will
anyway, since I'm from Baton Rouge and I don't want anyone to think we have
that mindset. Very, very few people from there are so narrow minded.  Maybe
no one should have fought against Hitler.  I'm sure we'd all be living in a
much more peaceful world.

A starfield springs to mind. It might need large brightly coloured nebulae
to be visible, though...

Or a planetarium/observatory type building? Where you could see the 
reflection of a large telescope in the planets? Something like the 
middle picture of http://en.wikipedia.org/wiki/Telescope

That's a grand idea.  It also gave me another idea - maybe have everything
floating in freefall inside the Shuttle or ISS?  Now to get to work ...

Mike:

I loaded your two images into Gimp as layers and did a difference between the two. 
After adjusting
the color curve a bit, here's the result.  You can easily find the differences now. 
(Some of it may
be due to conversion to the jpg format.)

That's a random quote from a long list. In no way can it relect the mindset of 
everybody, it was lifted from a public toilet wall.
Here's another one below.

Much more optimistic!  I'll have to remember that one.
