NASA NSTAR 30-cm ion thruster
Exact NASA NSTAR 30-cm xenon gridded-ion thruster variant flown on Deep Space 1 and used in the Dawn-class propulsion system. JPL documents a 0.5–2.3 kW operating range, 19–92 mN thrust, and 1,900–3,200 s specific impulse; spacecraft-specific configuration records remain outside this propulsion row.
