During the next five years, NASA technology development efforts should focus on 16 high-priority technologies and their associated top technical challenges, says a new report from the National Research Council. In addition, the report recommends emphasis on flight demonstrations for technologies that are nearly ready and a 10 percent allocation from the existing program budget to advance and refine early emerging technologies.

"It has been years since NASA has had a vigorous, broad-based program in advanced space technology development," said Raymond Colladay, president of RC Space Enterprises Inc., and chair of the committee that wrote the report. "Success in executing future NASA space missions will depend on advanced developments that should already be under way."

The 16 high-priority technologies were selected with input from the external technical community as part of NASA's draft technology roadmaps and include items such as radiation mitigation; guidance, navigation, and control; nuclear systems for both power generation and transportation; and solar power generation (see full table below).

These priorities were chosen to align with three main facets of NASA's overall mission: extending and sustaining human activities beyond low Earth orbit; exploring the evolution of the solar system and the potential for life elsewhere; and expanding our understanding of Earth and the universe.

The report sets forth an evaluation framework to prioritize which technologies to emphasize in the next five years of the 20- to 30-year window. NASA's Office of the Chief Technologist (OCT) should establish a rigorous process to select among competing technologies at appropriate milestones in order to ensure that the most promising ones receive sufficient attention and resources.

The report also recommends that OCT pursue cooperative development of high-priority technologies with other government agencies and the U.S. commercial space industry to leverage resources.

For technologies deemed closer to implementation, flight demonstrations, while expensive, are sometimes essential to transition a technology to an operational system, the report stipulates. Such technology flight demonstrations should be considered on a case-by-case basis when there is ample support from the user, including a reasonable level of cost-sharing.

To further foster collaboration, OCT should make the scientific and technical data that NASA has acquired from past and present space missions and technology development more readily available to U.S. industry, the report adds. This should include companies that do not have an ongoing working relationship with NASA and that are pursuing their own commercial goals, which may differ from NASA's science and exploration missions.

"If NASA can sustain implementation of its technology roadmaps - shaped by the priorities recommended in this study - they will form a solid foundation," said Colladay. "This foundation will support a breadth of NASA missions, as well as commercial and national needs, and provide the agency with the means to achieve its long-term goals."
