Synopsis of the Results of the

March 2010 1 Why We Explore

• More tangible benefits: – Exploration Preparation – Credible plans for science – Technology for space and Earth – Economic development and industrial capability • Less tangible benefits – U.S. leadership of international ventures – Engagement of the public – Inspiration of the youth, and excitement about STEM

2 A Space Faring Civilization

• We explore to chart a path for human expansion into the . • should be the ultimate destination for that exploration in the inner solar system • Staying on Mars, and extending human civilization within the solar system should be the ultimate goal. • This will require a lengthy commitment. • But it is time to begin.

These goals should drive destinations and systems

1. What is the phase out plan of the Shuttle? 2. What is the future of the ISS? 3. Should the government developed launch system be based on NASA/Shuttle heritage or an EELV heritage systems? 4. How should crew be carried to LEO (ISS in particular)? 5. What is the strategy for exploration beyond LEO?

Plus implicitly, what is the budget level

Fix performance and budget level, use schedule as independent variable

Goal – Understand how to live and work in free space under the conditions we will meet on the way to Mars, gather science knowledge and support science operations A Flexible Path of Human and Robotic Exploration: • Crewed exploration missions to many places in the inner solar system • Orbit planets with deep gravity wells, but do not land on the surface • Rendezvous with small planetary bodies such as NEOs and Mars’ moon Phobos • Tele -robotically explore and sample planetary surfaces A fundamentally new mode of human exploration, in close cooperation with robotics
