GREENBELT, Md., July 6 /PRNewswire/ -- The NASA Institute for Advanced Concepts (NIAC) announces the selection of sixteen proposals that could radically advance space exploration.

NIAC selected eleven proposals for Phase 1 awards, six-month investigations beginning in September, and five proposals for Phase 2 awards, more detailed studies 18 to 24 months in duration, also beginning in September. If these proposals become reality, the future of space exploration could include engines "turbocharged" by particle accelerators; a space-borne solar shield four times the area of Texas to stop global warming; biological batteries in the form of "power skins" that reap electricity from Martian winds or fuel cells that produce electricity and food while treating waste; and a space radiation shield made from electrically-charged gas and magnetic fields.

"NIAC's focus on visionary advanced concepts raises possibilities of performance enhancements for currently planned missions and may enable future missions that are currently viewed as nearly impossible," said NIAC Director Robert Cassanova of the Universities Space Research Association (USRA), Columbia, Md. "These recently selected proposals will explore the limits of our understanding of scientific principles and enabling technology." The USRA runs NIAC for NASA.

NIAC was created in 1998 to solicit revolutionary concepts from people and organizations outside the agency that could advance NASA's missions. The proposals push the limits of known science and technology, and positive results are not expected for at least a decade or more.

Proposals selected for Phase 1 awards typically receive up to $75,000 for a six-month study that validates the viability of the concept and identifies challenges that must be overcome to make the proposal a reality. The results of the Phase 1 studies are evaluated, and the most promising are selected for further research into the major feasibility issues associated with cost, performance, development time, and technology through a Phase 2 award. Phase 2 studies can be up to two years long and receive as much as $400,000.
