Mission scenarios outside the Earth's protective magnetic shield are being studied. Included are high usage assets in the near-Earth environment for casual trips, for research, and for commercial/operational platforms, in which career exposures will be multi-mission determined over the astronaut's lifetime. The operational platforms will serve as launching points for deep space exploration missions, characterized by a single long-duration mission during the astronaut's career. The exploration beyond these operational platforms will include missions to planets, asteroids, and planetary satellites. The interplanetary environment is evaluated using convective diffusion theory. Local environments for each celestial body are modeled by using results from the most recent targeted spacecraft, and integrated into the design environments. Design scenarios are then evaluated for these missions. The underlying assumptions in arriving at the model environments and their impact on mission exposures within various shield materials will be discussed.
正在研究地球保护性磁屏蔽之外的任务场景。其中包括近地环境中的高使用资产，用于休闲旅行、研究以及商业/运营平台，在这些场景中，职业暴露将根据宇航员的一生多任务情况来确定。这些运营平台将作为深空探索任务的发射点，其特点是在宇航员职业生涯中有一次长时间的任务。超越这些运营平台的探索将包括前往行星、小行星和行星卫星的任务。利用对流扩散理论评估行星际环境。通过使用最新目标航天器的结果对每个天体的局部环境进行建模，并将其整合到设计环境中。然后对这些任务的设计方案进行评估。将讨论得出模型环境的基本假设及其对各种屏蔽材料内任务暴露的影响。
