An automated, cyclic life test was performed to demonstrate the reliability and endurance of a low power dc cycle arcjet thruster. Over 1000 hr and 500 on-off cycles were accumulated which would represent the requirements for about 15 years of on-orb

The combination of spacecraft electrical power and on-board propulsion can consume as much as three-fourths of the mass of a spacecraft depending upon the mission. With the current emphasis on reducing costs (including launch vehicle costs) and on re

Onboard spacecraft power and propulsion are two of the essential utilities provided on a spacecraft. Together, these two subsystems can comprise one-half to over three-fourths of the launch mass of a spacecraft. What is not often realized is that the
