Due to limited electric power the thrust is much weaker compared to chemical rockets, but electric propulsion can provide thrust for a longer time. [2] Electric propulsion was first demonstrated in the 1960s and is now a mature and widely used technology on spacecraft. American and Russian satellites have used electric propulsion for decades.

Space Electric Rocket Test, suborbital (31 min), the first demonstration of an ion engine in space - only the mercury engine by NASA was operated Program 661A Flight B: 29 Aug 1964: 29 Aug 1964: Ion engine: 1: Cesium: USAF: EOS: Suborbital, experimental test (19 min operation) Zond 2: 30 Nov 1964: 14 May 1965: Pulsed plasma thruster: PTFE ...
Ion propulsion systems were first demonstrated in space by the NASA Lewis (now Glenn Research Center) missions Space Electric Rocket Test (SERT)-1 and SERT-2A. [25] A SERT-1 suborbital flight was launched on 20 July 1964, and successfully proved that the technology operated as predicted in space.
Atmosphere-breathing electric propulsion, or air-breathing electric propulsion, shortly ABEP, [1] is a propulsion technology for spacecraft, which could allow thrust generation in low orbits without the need of on-board propellant, by using residual gases in the atmosphere as propellant. Atmosphere-breathing electric propulsion could make a new ...
For rocket-like propulsion systems, this is a function of mass fraction and exhaust velocity; mass fraction for rocket-like systems is usually limited by propulsion system weight and tankage weight. [ citation needed ] For a system to achieve this limit, the payload may need to be a negligible percentage of the vehicle, and so the practical ...
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 ...
The xenon ions are then accelerated by the electric field between the anode and the cathode. For discharge voltages of 300 V, the ions reach speeds of around 15 km/s (9.3 mi/s) for a specific impulse of 1,500 s (15 kN·s/kg). Upon exiting, however, the ions pull an equal number of electrons with them, creating a plasma plume with no net charge.
It was designed to use a disposable jet engine up to an altitude of 15 km (9.3 mi) and then ignite its main hydrogen peroxide rocket engine in order to propel it to the 100 km (62 mi) altitude. On September 9, 2004, ARCA successfully launched the Demonstrator 2B rocket from Cape Midia Air Force Base.
