open-in-new
<p>The NASA Solar Technology Application Readiness (NSTAR) is a type of spacecraft <a href="/facts/Ion_thruster/cjt6M89p">ion thruster</a> called <a href="/facts/Electrostatic_ion_thruster/50nhqRvG">electrostatic ion thruster</a>. It is a highly efficient low-thrust <a href="/facts/Spacecraft_propulsion/KmpMGU9u">spacecraft propulsion</a> running on electrical power generated by <a href="/facts/Solar_arrays/rD4rcJB8">solar arrays</a>. It uses high-voltage <a href="/facts/Electrode/251PaKX8">electrodes</a> (including two fine grids) to accelerate <a href="/facts/Ion/3bePpDna">ions</a> with <a href="/facts/Electrostatic/bxkuW6s4">electrostatic</a> forces. </p>
