The gold in spacecraft goes into thermal blankets and electronics silly! Said golden thermal blankets don't really cost that much either because they contain such miniscule amounts of gold. In fact you can pick up golden thermal blankets at your local camping store for not much more than $5.

Said thermal blankets do protect against radiation though, as in the infrared-visible type.

Is it possible to build a stealth spaceship?
