奥巴马总统最近宣布，美国宇航局将在2025年前对一颗小行星进行载人使命。本文确定了2018年至2030年第一次载人使命的近地天体（近地天体）的最佳目标候选者。对近地天体数据库中轨道要素符合预定要求的目标小行星进行分析，以便进行使命设计。然后提出了满足五个指定候选近地天体要求的系统结构。还讨论了今后可用于载人近地物体飞行任务的其他技术，并分析了以前的近地物体目标选择研究。虽然第一次近地天体使命仍需要研制一些重型运载火箭，但设计实例表明，第一次使命可在2025年前完成。战神V和Orion CEV被用作本研究的基线系统架构。
President Obama has recently declared that NASA will pursue a crewed mission to an asteroid by 2025. This paper identifies the optimum target candidates of near-Earth objects (NEOs) for a first crewed mission between 2018 and 2030. Target asteroids in the NEO database with orbital elements that meet predetermined requirements are analyzed for mission design. System architectures are then proposed to meet the requirements for five designated NEO candidates. Additional technology which can be applied to crewed NEO missions in the future is also discussed, and a previous NEO target selection study is analyzed. Although some development of heavy launch vehicles is still required for the first NEO mission, design examples show that a first mission can be achieved by 2025. The Ares V and the Orion CEV are used as the baseline system architecture for this study.
