Are you talking about modeling the MISR Terra Spacecraft out of Lego?

Unless the scale is really out of control, I would guess that it could be done
pretty cheaply - unless you wanted to motorize it and use Mindstorms.

I would suggest a can of spray paint. That is the cheapest way to coat bricks
with gold or silver colors. I actually painted bricks silver when I was a
kid, although they didn't look as good as the real silver bricks we have
today.

Go to www.ldraw.org and read about MLCAD, which is what you want. It uses the
parts library for an older DOS based program called LDraw, which you will also
need to download and run to create your parts library. MLCAD is about as easy
to use as a Lego CAD program can be.

The main reason for no catalog of parts is that (1) Lego doesn't offer one and
(2) everyone has their own name for an obscure part and Lego hasn't set a
standard. There are some people working on one, but it is way off from being
finished.

Not likely to happen after the Lego Concentration Camp set an artist made.

| (...) MISR is one of 5 instruments bolted onto the Terra platform. I am interested only in a model of what's under MISR's radiation shielding, and at that, only certian parts. Check out www-misr.jpl.nasa.gov and navigate to the EOS site for a more (...) (25 years ago, 5-Nov-99, to lugnet.build)
