What's Happening?
NASA is calling for scientific collaboration to better understand the biological responses to space radiation, which poses significant health risks to astronauts. The agency is particularly interested in studying the effects of radiation from solar energetic
particles and galactic cosmic rays, which can lead to increased risks of cancer, cardiovascular disease, and central nervous system damage. NASA plans to use outbred animal models, specifically genetically diverse mice, to simulate human responses to spaceflight. The study aims to determine the effects of radiation quality, dose, and dose rate on cancer initiation and progression, and to establish estimates for space-relevant radiation exposures. The research will be conducted at the NASA Space Radiation Laboratory in Upton, New York, and will include comprehensive tissue collection and biobanking to support future investigations.
Why It's Important?
Understanding the effects of space radiation is crucial for the safety and health of astronauts, especially as NASA plans more extended missions, such as those to Mars. The research could lead to improved risk assessments and the development of better protective measures against radiation exposure. This initiative is part of NASA's broader effort to ensure the success and safety of future space missions, which are critical for advancing human exploration of space. The findings could also have implications for radiation protection on Earth, potentially benefiting industries and healthcare sectors dealing with radiation exposure.
What's Next?
The project is set to begin with a definition phase lasting 3-6 months, followed by a full implementation phase contingent on successful integration with NASA's scientific goals. Researchers interested in participating must submit their proposals by March 13, 2026. NASA will provide the necessary resources, including animal models and beam time at the laboratory, while researchers will be responsible for model housing, travel, and experimental execution. The outcomes of this research could influence future space mission planning and astronaut training programs.
