Today electric propulsion is considered or being used for several applications such as orbit raising/orbit topping and station keeping of telecommunication satellites, orbit maintenance and deorbiting of constellations of small satellites (OneWeb, LEOSAT, SpaceX, etc.), for transfer manoeuvers (e.g. BepiColombo transfer to Mercury), formation flying of satellites, etc. The required thrust...

Low power electric propulsion is an enabling technology for a number of future missions, especially the ones involving mini- and micro- satellites. Currend trend is to launch many low-cost spacecraft to accomplish a wide variety of tasks, ranging from Earth monitoring to communication. A brilliant example of it is the idea of developing a constellation of small satellites placed in LEO and...

The increase of available power on board of modern spacecraft is paving the way to the use of very high power electric propulsion systems for a variety of deep space exploration missions to cislunar space, asteroids and planets of the inner solar system, as well as private commercial space missions. Hall thruster technology offers a favourable combination of performance, reliability, and...

The Hall thruster (HT) is a gridless positive ion accelerator used for spacecraft propulsion. The original idea of ion acceleration in a quasi-neutral magnetized plasma discharge was introduced in the mid-1960s. The first HT was successfully operated in space in 1972 aboard the former USSR Meteor satellite. Since that time numerous works have been performed, the technology has greatly evolved...

Since the first launch on board of the Russian satellite of Meteor series Hall effect thruster (HET) has become a serious competitor for the classic rocket technology as far as station keeping and positioning, orbit rising or even deep space mission driving is concerned. Despite of the fact that lasting more than 50 years development of HET resulted in the matured and well optimized design,...

The possibility of realizing a high thrust-over-power collisional Hall thruster will be discussed.
A major figure of merit in propulsion in general and in electric propulsion in particular, is the thrust per unit of deposited power, the ratio of thrust over power. We have recently demonstrated experimentally and theoretically [1-5] that for a fixed deposited power in the ions, the momentum...
