// PROPULSION SYSTEMS AND ENGINE TECHNOLOGY TERM
VASIMR
VASIMR stands for Variable Specific Impulse Magnetoplasma Rocket, an advanced electric propulsion system that heats propellant into a plasma and then accelerates it using magnetic fields.

TECHNICAL DEFINITION
The Variable Specific Impulse Magnetoplasma Rocket (VASIMR) is an electrodeless plasma propulsion engine designed for high-efficiency spacecraft propulsion, utilizing radio frequency waves to ionize and heat a propellant gas into a superheated plasma, which is then accelerated to generate thrust via magnetic nozzles.
BACKGROUND
A plasma propulsion engine is a type of electric propulsion that generates thrust from a quasi-neutral plasma. This is in contrast with ion thruster engines, which generate thrust through extracting an ion current from the plasma source, which is then accelerated to high velocities using grids of anodes. These exist in many forms. However, in the scientific literature, the term "plasma thruster" sometimes encompasses thrusters usually designated as "ion engines".
