NASA Selects 12 Research Proposals In Radiation Biology
Houston TX (SPX) Sep 13, 2006 NASA will fund a dozen new research proposals to better understand and reduce the risks that crews of future moon and Mars missions could face from space radiation. The total potential value of the selected proposals is approximately $14 million. The health risks of radiation during space travel may include cancer, degenerative tissue damage -- including damage to the central nervous system -- and acute radiation sickness. The new research may help in the development of effective shielding or biological countermeasures for radiation exposure. The research is part of NASA's Space Radiation Program. The goal of the program is to assure astronauts can safely live and work in the space radiation environment, anywhere, anytime. Space radiation is different from forms of radiation encountered on Earth. Radiation in space consists of high-energy protons, heavy ions and secondary byproducts created when the protons and heavy ions pass through spacecraft shielding and human tissue. Since the data available on human exposure to these radiation types are limited, the risks of exposure are derived from an understanding based on radiation physics and radiation biology. The more research data collected, the more confident NASA can be that astronauts will be protected. The 12 new research areas were selected by the Space Radiation Program from 82 proposals received in response to a NASA Research Announcement. All of the proposals were peer-reviewed by scientific and technical experts from academia, government, and industry.
