For many space engineers, the Space Exploration Initiative - the first President Bush's July 1989 call for a return to the moon and a voyage to Mars - was a process of rediscovery. Few knew about Apollo-era plans, so at first they opted for a costly lunar base design that helped to kill Bush's initiative. Had they known their history, however, they might have skipped right away to economical moon base plans based on designs a generation old. One such plan - put forward, alas, when it was already too late - was Boeing's 1991 Lunar Campsite.
"Anything is possible. You can be told that you have a 90-percent chance or a 50-percent chance or a 1-percent chance, but you have to believe, and you have to fight." -- Lance Armstrong, 21st century cyclist and 6 time Tour de France winner
