Over the past 20 years, the pace of space exploration has slowed significantly compared to the fifties to nineties of the XX century. Тhe lack of the possibility of the qualitative development of interplanetary research and technological missions, due to the extremely low ratio of the mass of the payload to the mass of the spacecraft equipped with traditional chemical engines. This low ratio is explained by the small specific impulse of traditional chemical engines. A solution to the problem of increasing specific impulse has existed since the 60s of the XX century. This is the widespread implementation of electrical rocket thrusters, i.e. Electric Propulsion Thrusters (here and after is referred as EPT), the most promising models of which today have a specific impulse more than 20 times higher, than the specific impulse of modern chemical rocket thrusters.
