Large increase in payload can be achieved when electrical propulsion is used instead of chemical propulsion; for missions in gravitational field of Earth and to Moon, optimum specific impulse range for electrical propulsion is from about 1500 to 5000 sec; electrical propulsion with neutral plasma devices operate well in this specific impulse range; three different chambers using neutral plasmas described.
