Mars mission Risk 29: Scientists research ways to reduce radiation-induced brain damage

...jectory involves flying around Venus and using its gravitational pull to sling the spacecraft toward Mars. That means flying closer to the sun and spending months on the opposite side. "The sun is basically a big nuclear reactor," said Britten. The scientists hope to determine how much shielding the spacecraft...
