WebDec 6, 2024 · Robustness against a missed-thrust contingency is vital for continuous thrust missions. An ion engine sometimes stops for several reasons, such as occasional discharge phenomena on the thruster grids, single event phenomena in the thruster control electronics, and spacecraft temporal malfunctions. WebFor high thrust, power is routed predominantly to the first stage producing more plasma (more thrust) at a lower exhaust velocity (low Isp). For high Isp, less power is fed to the first stage and more to the second, reducing the plasma production but increasing its temperature and hence its exhaust velocity. High power density.
