the default texture function of OpenGL is GL_REPLACE and that is what
the SimpleTexturedMaterial uses as default for the envMode field. Also
my OpenGL book recommends using a specular color of white for objects
and let the texture provide the diffuse color.
If you modify your code to contain lines like:
beginEditCP(texEarth);
texEarth->setImage(imageEarth);
texEarth->setEnvMode(GL_MODULATE);
texEarth->setSpecular(Color3f(1.0f, 1.0f, 1.0f));
endEditCP(texEarth);
you will get the desired effect.
