I suppose these lower res meshes are posted by NASA in order to reduce 
the 'weight' of the files.

What you can do with your own meshes is to subdivide them in Poseray. 
However, you may be in trouble rapidly as the file becomes too large for 
OpenGL to redraw the mesh, I found out. I don't know if the subdivided 
mesh can still be saved (I didn't try). Somebody with a better suggestion?
