An ion drive is a A type of [[:category:propulsion|propulsion]] that uses an electric field to accelerate charged particles and eject them at high velocities (in . In some designs, the ion particles have been known to approach the speed of light).   This type of propulsion is used by many pre-[[warp]] civilizations to propel [[probe|probes]] and lightweight [[starship|spacecraft]] once they are in open [[space]].   The thrust produced is considered quite gentle, and often requiring requires anywhere from hours to weeks to reach full velocity.    '''Also see: [https://www.nasa.gov/centers/glenn/about/fs21grc.html Ion propulsion according to NASA's Glenn Research Center]'''      [[category:engineering]][[category:starship Systems]][[category:propulsion]]
