JFK 1961 • Mercury • Gemini • Six Apollo landings 1969-1972 “I believe this nation should commit itself to achieving the goal, before this decade is out, of landing a man on the Moon and returning him safely to the Earth”
Societal Benefits of the Apollo Program • Humans can live on the Moon and Mars • Sustainable resources can be found • Hydrogen, oxygen, water • Advances in Technology • Identification of space hazards and risks • Potential new energy sources from space
How Does the Space Program Benefit YOU? • Computer miniaturization • Weather forecasting • Communications • Navigation (GPS) • Global ecosystem & climate observations & resource management Mainframe IBM computer, early 1970’s
What did we learn from the Moon? • Origin and Evolution of 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 • Lunar Resource Potential • Future Lunar Scientific Potential
