For centuries, for thousands of years, men on Earth had looked up at the moon and wondered what was up there. They regarded it with a sort of mystique. And it's always hard to recreate the same level of excitement you get with something new.

Nevertheless, the challenge and the opportunities for space flight are very exciting, even though they might be different from Apollo.
