Man's exploration of space is often analogized to his exploration of the ancient oceans. Ancient sea-explorers faced obstacles of uncharted oceans and land. They also faced difficulties in finding the means and financing to make their discoveries. Space industrial development suffers difficulties as well, however, many of the difficulties are legal obstacles.
