美国宇航局格伦研究中心已被选为领导美国宇航局进化氙气推进器（NEXT）系统的开发。 NEXT系统的核心特征是电力推进推进器（EPT），它继承了通过NSTAR推进器获得的知识，成功地将深空1号推进到小行星盲文和博雷利彗星，同时显着提高推进器功率水平并改进与NSTAR相关的性能参数。正在开发的EPT概念的光束直径为40厘米，是深空1号推进器有效面积的两倍，同时保持相对较小的体积。它结合了机械特性和操作条件，以最大限度地发挥 NSTAR 30 厘米飞行发动机所建立的设计传统，同时结合新技术，以扩展功率和吞吐能力。
NASA’s Glenn Research Center has been selected to lead development of NASA’s Evolutionary Xenon Thruster (NEXT) system. The central feature of the NEXT system is an electric propulsion thruster (EPT) that inherits the knowledge gained through the NSTAR thruster that successfully propelled the Deep Space 1 to asteroid Braille and comet Borrelly, while significantly increasing the thruster power level and making improvements in performance parameters associated with NSTAR. The EPT concept under development has a 40 cm beam diameter, twice the effective area of the Deep-Space 1 thruster, while maintaining a relatively-small volume. It incorporates mechanical features and operating conditions to maximize the design heritage established by the flight NSTAR 30 cm engine, while incorporating new technology where warranted to extend the power and throughput capability.
