Hello Mark;
Building a LEGO model of this satellite sounds like an excellent
project.
Some thoughts on the ongoing discussion:

My brother-in-law happens to own Alberta Industrial Models. A $10K
estimate would not be out of line, depending on the scale of the
model.
Most people just don't think about the time involved in custom models.
A few hundred hours multiplied by a $40/hour shop rate adds up real
quick. Materials on top of that.
OTOH, AIM wants to do more film work. If a LEGO model isn't feasible
for some reason, they might do it for considerably less so they can
say they're worked for JPL. A feather in anyone's cap.

That's a good point. OTOH, if the model is being used as a public
demonstration model, especially for kids (at any level), LEGO would
make it more interesting to that audience.

Yes, acquiring the parts you need could be far more difficult than
actually designing and building it.
So how big will the LEGO model of the MISR be?
Will you model the entire spacecraft including the solar panel? or
just the instrument package.?
If you have the option, I would model everything. Using an RCX and
motors to extend the solar panel would be very interesting.
From the spacecraft image I can't tell how the solar panels unfold. I
have seen several different approaches taken by NASA and JPL. Which
deployment will this utilize?
You could have removable panels that show the guts of the spacecraft.
Breaking down further till you get to the pieces you'd like to show.
The level of detail needed here will determine how big the model will
be I guess. Or you could build a spacecraft model at one scale, and
one of the cameras at another.

I know this is an expensive process. Paint will be cheaper. If
airbrushed by someone who knows what they're doing it will look fine
painted.
Good luck Mark. I look forward to hearing about your progress on
this, and seeing some pictures.
This job could mean you become Master LEGO Builder for JPL & NASA.
What a career move. :-)
