Why, in your opinion, does the space program require justification? Is it the expense? I would counter that the expense of a thing should not be the overwhelming factor in its consideration. Just because something is expensive, does not mean it is not worth doing. Otherwise, we would all be huddling in mud huts and carting around cow dung for a living.
