The Mars Science Laboratory spacecraft, containing the Curiosity rover, was launched to Mars on 26 November 2011, and for most of the 253-day, 560-million-kilometer cruise to Mars, the Radiation Assessment Detector made detailed measurements of the energetic particle radiation environment inside the spacecraft. These data provide insights into the radiation hazards that would be associated with a human mission to Mars. We report measurements of the radiation dose, dose equivalent, and linear energy transfer spectra. The dose equivalent for even the shortest round-trip with current propulsion systems and comparable shielding is found to be 0.66 ± 0.12 sievert.
“火星科学实验室”航天器于 2011 年 11 月 26 日发射升空，前往火星，在飞往火星的 253 天、5.6 亿公里的航程中，辐射评估探测器对航天器内部的高能粒子辐射环境进行了详细测量。这些数据为人类探索火星可能面临的辐射危害提供了深入了解。我们报告了辐射剂量、剂量当量和线性能量转移谱的测量结果。即使使用当前的推进系统和类似的屏蔽措施，进行最短的往返飞行，其剂量当量也被发现高达 0.66 ± 0.12 西弗特。
