Last month, the investigators on the Radiation Assessment Detector (RAD) instrument aboard NASA’s Curiosity rover announced some of their findings. According to the scientists, the RAD measurements indicate that the crew of a human Mars expedition using present-day propulsion technology (six-month transits each way, 18 months on the surface) would receive a round-trip radiation dose of about 0.6 Sievert (Sv), or 60 rem (1 Sv = 100 rem.)
