The Advanced Electric Propulsion System qualification thruster inside one of the vacuum chambers at NASA Glenn’s Electric Propulsion and Power Laboratory. Advanced Electric Propulsion System (AEPS) is a solar electric propulsion system for spacecraft that is being designed, developed and tested by NASA and Aerojet Rocketdyne for large-scale ...
Selected advanced electric propulsion projects developed propulsion technology systems in the 50 to 300 kilowatts (67 to 402 hp) range to meet the needs of a variety of deep space mission concepts. The three NextSTEP advanced propulsion projects, $400,000 to $3.5 million per year per award, were limited to a three-year performance period ...
As of 2019, over 500 spacecraft operated throughout the Solar System use electric propulsion for station keeping, orbit raising, or primary propulsion. [4] In the future, the most advanced electric thrusters may be able to impart a delta-v of 100 km/s (62 mi/s), which is enough to take a spacecraft to the outer planets of the Solar System (with ...

The NASA mission to the asteroid Psyche utilizes xenon gas Hall thrusters. [44] The electricity comes from the craft's 75 square meter solar panels. [45] NASA's first Hall thrusters on a human-rated mission will be a combination of 6 kW Hall thrusters provided by Busek and NASA Advanced Electric Propulsion System (AEPS) Hall
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. [2] A beam extraction area 1.6 times that of NSTAR allows higher thruster input power while maintaining low voltages and ion current densities, thus maintaining thruster longevity.
Field-emission electric propulsion (FEEP) is an advanced electrostatic space propulsion concept, a form of ion thruster, that uses a liquid metal as a propellant – usually either caesium, indium, or mercury. [1] A FEEP device consists of an emitter and an accelerator electrode.
Since 2011, White had a team at NASA known as the Advanced Propulsion Physics Laboratory, or Eagleworks Laboratories, devoted to studying exotic propulsion concepts. [79] The group investigated ideas for a wide range of untested and fringe proposals , including Alcubierre drives , drives that interact with the quantum vacuum , and RF resonant ...
