[×ÊÔ´] NASA Space Technology Roadmaps and Priorities

NASA Space Technology Roadmaps and Priorities: Restoring NASA¡¯s Technological Edge and Paving the Way for a New Era in Space
Steering Committee for NASA Technology Roadmaps  National Research Council of the National Academies

This report provides specific guidance and recommendations on how the effectiveness of the technology development program managed by OCT can be enhanced in the face of scarce resources.

NASA's Office of the Chief Technologist (OCT) has begun to rebuild the advanced space technology program in the agency with plans laid out in 14 draft technology roadmaps. It has been years since NASA has had a vigorous, broad-based program in advanced space technology development and its technology base has been largely depleted. However, success in executing future NASA space missions will depend on advanced technology developments that should already be underway.
Reaching out to involve the external technical community, the National Research Council (NRC) considered the 14 draft technology roadmaps prepared by OCT and ranked the top technical challenges and highest priority technologies that NASA should emphasize in the next 5 years.
