近 50 年来，NASA 一直致力于利用高功率太阳能电力推进来提高太空运输的可承受性。早期的工作重点是可用于航天飞机的 25 至 50 千瓦系统，而后来的工作重点是可用于重型运载火箭的功率高出近一个数量级的系统。这些努力从未离开概念开发阶段，部分原因是所需的技术还不够成熟。自 2012 年以来，NASA 空间技术任务理事会制定了一项协调计划，以成熟实施 30 至 50 千瓦太阳能电力推进技术示范任务所需的太阳能电池阵和电力推进技术。基于这些成熟技术，已经开发了多种太阳能电力推进技术演示任务概念，最近的工作重点是小行星重定向机器人任务。如果实施，小行星重定向飞行器将成为一种能力的基础，随着时间的推移，这种能力可以经济高效地发展，为一系列功率水平超过 100 千瓦的后续任务应用提供太阳能电力推进运输。
NASA has sought to utilize high-power solar electric propulsion as means of improving the affordability of in-space transportation for almost 50 years. Early efforts focused on 25 to 50 kilowatt systems that could be used with the Space Shuttle, while later efforts focused on systems nearly an order of magnitude higher power that could be used with heavy lift launch vehicles. These efforts never left the concept development phase in part because the technology required was not sufficiently mature. Since 2012 the NASA Space Technology Mission Directorate has had a coordinated plan to mature the requisite solar array and electric propulsion technology needed to implement a 30 to 50 kilowatt solar electric propulsion technology demonstration mission. Multiple solar electric propulsion technology demonstration mission concepts have been developed based on these maturing technologies with recent efforts focusing on an Asteroid Redirect Robotic Mission. If implemented, the Asteroid Redirect Vehicle will form the basis for a capability that can be cost-effectively evolved over time to provide solar electric propulsion transportation for a range of follow-on mission applications at power levels in excess of 100 kilowatts.
