Microthruster

Microthruster

 

a rocket motor with a thrust of several dozen newtons to several hundredths of a newton that can be fired repeatedly and operated a large number of times. Micro-thrusters are used mainly for stabilization and attitude control, and also as individual engines to move an astronaut in free flight outside a spacecraft.
