•Cold War Political Goals of Eisenhower and Kennedy to Advertise Free Institutions Were Met•Soviet Union Leadership Impressed
–Reagan’s Strategic Defense Initiative Later Became Creditable
•America Succeeded - Soviets Did Not•Pride and Confidence of Humankind Enhanced•Peoples of Earth Encouraged About Their Future•“Space-faring” became an International Imperative

APOLLO’S SOCIETAL LEGACYAPOLLO’S SOCIETAL LEGACY• New Evolutionary Status
– Human Species Can Live on Moon and Mars• Rapid Improvement in Human Condition on Earth
– Acceleration of Technological Expansion– Hazard Definition and Risk Determination
• Future Terrestrial Energy and Environmental Improvement– Conversion Efficiencies Enhanced– Lunar Helium-3 Fusion and Solar Power Options Identified
• Space Settlement Resources Identified on the Moon– Hydrogen, Oxygen, Water, and Food

APOLLO’S SCIENTIFIC APOLLO’S SCIENTIFIC LEGACYLEGACY
• First Order Understanding of Origin and Evolution of the Moon
• Basis for Interpretation of Post-Apollo Information About the Moon– Foundation for Comparative Planetology
• Record of History of Inner Solar System– Initial Guide to Early History of Earth and Mars– Conditions for the Initiation of Life
• Delineation of Lunar Resource Potential• Delineation of Future Lunar Scientific Potential
REMARKABLE!

What Was the Largest Mistake After Apollo?
•The Development Cost of Apollo Created Was Not Amortized•Continued Use of the Saturn-Apollo Capabilities Would Have Provided:
•Periodic Access to the Moon•Capability for Asteroid or Comet Diversion•Skylab-style Station for Characterization of Human Adaptation to Micro-gravity•Other Micro-gravity applications?
•Enhancement of the Saturn-Apollo Capabilities Would Have Provided:
•Low Cost Access to Lunar Resources•Basis for Large Scale Robotic and Human Exploration of Mars

Why Return to the Moon?• Satisfy basic human instincts for exploration
– Freedom, betterment, curiosity– New homelands, trade, and knowledge
• Continue at least 40,000 years of exploration’s benefits to modern humans– New homes, livelihoods, know-how, resources– Supported by both “government” and private initiatives
• Perpetuate exploration and settlement of space– Comparable to past migrations into our global habitat– Opportunity for the expansion of free institutions

•Outer Space Treaty of 1967–Only Truly Operative Space Treaty Relative to Resources–Implementation of Moon Agreement would be Self-defeating
•1967 Treaty Permissive Relative to Access to Space Resources
–Private, Government, Multilateral or International Initiative Equally Permissible–Private Entity Must Be Sponsored (Licensed) by Party to Treaty
•Multilateral Private Property Regime Desirable

“The Psychological, Technological and Survival Bonds Holding
Humans to the Earth Have Been Broken. This New Evolutionary
Potential in the Universe Now Permits Us to Live on the Moon
and Mars. Generations Alive Today Can Determine If
Humankind Will Take Advantage of
This New Status. -- Will We Begin
the Settlement of the Solar System
and Provide for a New Birth
of Freedom Beyond
the Earth?”
APOLLO BENT OUR EVOLUTIONARY PATH INTO THE FUTURE.
