BOX ES-1 NASA's Three Pillars and Ten Enabling Technology Goals to Achieve National Priorities in Aeronautics and Space Transportation

Pillar One: Global Civil Aviation

Goal 1: Reduce emissions of future aircraft by a factor of three within 10 years and by a factor of five within 20 years.

Goal 2: Reduce the perceived noise levels of future aircraft by a factor of two from today's subsonic aircraft within 10 years and by a factor of four within 20 years.

Goal 3: Reduce the aircraft accident rate by a factor of five within 10 years and by a factor of 10 within 20 years.

Goal 4: While maintaining safety, triple the aviation system throughput, in all weather conditions, within 10 years.

Goal 5: Reduce the cost of air travel by 25 percent within 10 years, and by 50 percent within 20 years.

Pillar Two: Revolutionary Technology Leaps

Goal 6: Provide next-generation design tools and experimental aircraft to increase design confidence and cut the development cycle time for aircraft in half.

Goal 7: Invigorate the general aviation industry, delivering 10,000 aircraft annually within 10 years and 20,000 aircraft annually within 20 years.

Goal 8: Reduce the travel time to the Far East and Europe by 50 percent within 20 years and do so at today's subsonic ticket prices.

Pillar Three: Access to Space

Goal 9: Reduce the payload cost to low-Earth orbit by an order of magnitude, from $10,000 to $1,000 per pound, within 10 years.

Goal 10: Reduce the payload cost to low-Earth orbit by an additional order of magnitude, from $1,000's to $100's per pound by 2020.

The candidate breakthrough technologies identified during the workshop were further refined by three subgroups of the committee, which focused on air vehicle technology, air transportation system technology, and space transportation technology. The findings of these three subgroups are summarized in the following sections.
