本文概述了美国宇航局在电推进领域的活动，重点是计划方向，最近的进展，并认为未来的计划方向。高性能电力推进系统的好处已得到认可，新技术也已被接受。电力推进能够实现积极的科学任务，并为商业企业提供经济优势。NASA认识到未来太阳系任务需要新的高性能电力推进技术，并正在赞助这一领域的积极努力。这些工作是在航空航天技术厅和空间科学厅的领导下进行的。技术活动的基础广泛，以支持所有的NASA。大部分工作集中在行星科学任务的技术上。格伦研究中心领导该机构的电推进活动，并得到JPL，JSC和MSFC的支持。计划包括为十年末的任务开发下一代离子推进器。还计划作出更多的努力来开发非常高功率的推进器。离子簇和高功率霍尔推进器正在研究中。美国航天局继续与供应商和用户社区密切合作，以及时和具有成本效益的方式最大限度地接受新技术。NASA的电力推进工作与国防部和其他国家计划密切协调，以确保最有效地利用可用资源。
This paper provides an overview of NASA's activities in the area of electric propulsion with an emphasis on program directions, recent progress, and a view of future program directions. The benefits of high performance electric propulsion systems are recognized, and new technologies have been accepted. Electric propulsion enables aggressive science missions and provides an economic advantage for commercial ventures. NASA recognizes the need for new, high performance, electric propulsion technologies for future solar system missions and is sponsoring aggressive efforts in this area. These efforts are conducted under the Office of Aerospace Technology and the Office of Space Science. Technology activities are broadly based to support all of NASA. The majority of the work is focused on technology for planetary science missions. The Glenn Research Center leads the Electric Propulsion activities for the agency and is supported by JPL, JSC, and MSFC. Plans include the development of next generation ion thrusters for end of decade missions. Additional efforts are planned for the development of very high power thrusters. Clusters of ion and high power Hall thrusters are being studied. NASA continues to work closely with both supplier and user communities to maximize the acceptance of new technology in a timely and cost-effective manner. NASA’s electric propulsion efforts are closely coordinated with Department of Defense and other national programs to assure the most effective use of available resources.
