本文以用户为中心，对近期内可用于深空科学任务主推进的各种政府和商业太阳能电力推进选项进行了综合和比较，这类任务通常是NASA发现号计划建议的类别。与以前的论文不同，这项工作没有从任务分析的角度强调可行性。相反，它强调由竞争性审查的有成本上限的特派团提案独特地提出的要求，对这些提案来说，系统级飞行传统和成本可信度可以压倒纯粹的性能和任务捕获。它描述了飞行任务设计师和审查委员会可以用来选择和评价电力推进系统的标准，提供了可行的政府和商业电力推进系统备选方案，描述了使商业电力推进系统适应深空所需的修改，并讨论了商业电力推进系统成本的适当方法。它包含了..。
This paper offers a user-centric consolidation and comparison of the full range of government and commercial solar electric propulsion options available in the near term for primary propulsion on deep-space science missions of the class commonly proposed to NASA’s Discovery program. Unlike previous papers, this work does not emphasize feasibility from a mission-analysis perspective. Rather, it emphasizes requirements uniquely imposed by competitively reviewed cost-capped mission proposals, for which system-level flight heritage and cost credibility can trump sheer performance and mission capture. It describes criteria that mission architects and review boards can use to select and evaluate electric propulsion systems, provides descriptions of viable government and commercial electric propulsion system options, describes the modifications needed to adapt commercial electric propulsion systems to deep space, and discusses appropriate methods for costing commercial-based electric propulsion systems. It concl...
