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.

Its Rutherford engines are the first electric-pump-fed engine to power an orbital-class rocket. [17] Electron is often flown with a kickstage or Rocket Lab's Photon spacecraft. Although the rocket was designed to be expendable , Rocket Lab has recovered the first stage twice and is working towards the capability of reusing the booster. [ 18 ]
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 ...
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 ...
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 ...
High Power Electric Propulsion (HiPEP) is a variation of ion thruster for use in nuclear electric propulsion applications. [ 1 ] [ 2 ] [ 3 ] It was ground-tested in 2003 by NASA and was intended for use on the Jupiter Icy Moons Orbiter , which was canceled in 2005.
A nuclear electric rocket (more properly nuclear electric propulsion) is a type of spacecraft propulsion system where thermal energy from a nuclear reactor is converted to electrical energy, which is used to drive an ion thruster or other electrical spacecraft propulsion technology.
This is comparable to Robert Goddard's first test flight of his rocket design. Increasing the laser power to 100 kilowatts will enable flights up to a 30-kilometer altitude. They aim to accelerate a one-kilogram microsatellite into low Earth orbit using a custom-built, one-megawatt ground-based laser. Such a system would use just about 20 ...
