A Bold Vision for Space Exploration, Authorized by Congress

Complete the International Space Station Safely fly the Space Shuttle until 2010 Develop and fly the Crew Exploration Vehicle no later

than 2014 Return to the Moon no later than 2020 Extend human presence across the solar system and

beyond Implement a sustained and affordable human and robotic

program Develop supporting innovative technologies, knowledge,

and infrastructures Promote international and commercial participation in

exploration

The Administrator shall establish a program to develop a sustained human presence on the Moon, including a robust precursor program to promote exploration, science, commerce and U.S. preeminence in space, and as a stepping stone to future exploration of Mars and other destinations.

Exploration Strategy Themes

Use the Moon to prepare for future human and robotic missions to Mars and other destinations

Pursue scientific activities to address fundamental questions about the solar system, the universe, and our place in them

Extend sustained human presence to the moon to enable eventual settlement

Expand Earth’s economic sphere to encompass the Moon and pursue lunar activities with direct benefits to life on Earth

Strengthen existing and create new global partnerships

Engage, inspire, and educate the public

What’s the value of exploration?

Humans explore because it conveys an evolutionary advantage

exploration broadens experience and imagination, permitting better prediction of the future, ensuring better odds for survival

curiosity and its satisfaction is intellectually and emotionally satisfying

Exploration improves our ability to solve problems increased imagination and knowledge base permits recognition of innovative

approaches and solutions helps focus energies on posing the right questions, or, questions that can be

addressed and answered

Exploration excites and inspires the creative, productive segments of society

permits intellectual connections and relations that might not otherwise occur (the ‘ah-ha!’ syndrome)

Frontiers are unknown, mysterious places that stimulate imagination
