In
November 2010, it was revealed that the prototype had completed a 48,000 hours (5.5 years) test in December 2009. Thruster performance characteristics, measured over the entire throttle range of the thruster, were within predictions and the engine showed little signs of degradation and is ready

The NEXT thruster has demonstrated, in ground tests, a total impulse of 17 MN·s; which as of 2010 was the highest total impulse ever demonstrated by an ion thruster. A beam extraction area 1.6 times that of NSTAR allows higher thruster input power while maintaining low voltages and ion current

NEXT completed its System
Requirement Review in July 2015 and Preliminary Design Review in February 2016. The first two flight units will be available in early 2019. After 2019, it will be a commercial product for purchase by NASA and non-NASA customers. Aerojet Rocketdyne, and their major
