In this study, we analyze the power storage systems needed for operational tests of a Variable Specific Impulse Magnetoplasma Rocket (VASIMR) on the International Space Station (ISS). Two tests are considered: a short-term test of VASIMR operation in a space environment and long term drag compensation operation. Energy storage possibilities examined include nickel hydrogen, nickel cadmium, and lithium-ion batteries and flywheels. For the near-term planned tests, all approaches are technically
