Curiosity Data Show Astronauts Could Survive Mars Radiation

SPACE.com http://www.cbsnews.com/8301-205_162-57557075/nasa-astronauts-could-survive-mars-radiation/ (12/5, Wall) reports, “Astronauts could endure a long-term, roundtrip Mars mission without receiving a worryingly high radiation dose, new results from NASA’s Mars rover Curiosity suggest.” A mission “consisting of a 180-day outbound cruise, a 600-day stay on Mars and another 180-day flight back to Earth would expose an astronaut to a total radiation dose of about 1.1 sieverts (units of radiation) if it launched now, according to measurements by Curiosity’s Radiation Assessment Detector instrument, or RAD. That’s a pretty manageable number, researchers said.”
