• Resources – rare earth elements, water• Scientific discovery• Economic development/impact.• Technical gaps lead to discovery of new technologieswith practical uses.• Competition with other nations – Russia, China• Unify nations via ISS• Preserve human species – multiplanetary• Inspire next generation• Answer questions like are we alone?
It’s about the why!
Why
How
What
• Very few organizations know why they do what they do. What’s its purpose? Why does the organization exist?
• Example of thinking differently – Apple.
• How about America’s Space Program?

So, let’s be inspirational
• Humans are meant to explore. It is at our core. We explore to gain knowledge, satisfy our curiosity. Space is that next frontier. It is a simple answer to why we explore.
• Next questions: How do we explore?Where do we explore?What are the tools for exploration?

Additional Thoughts
• Drive advances in science and technology;• Expand opportunity for everyone, everywhere in space;• Enhance and expand knowledge, education, innovation, and
economic vitality;• Advance our understanding of Earth and develop technologies
to improve the quality of life on our home world.
We must begin with the Why which leads to the How and the What of space exploration. There is room for everyone!
Ideally, a well-designed and executed, inspirational, sustainable space program will
