ionpropelled

Ion propulsion is a type of electric propulsion used for spacecraft. It works by ionizing a propellant, typically a noble gas like xenon, and then accelerating these ions using an electric field. This acceleration expels the ions at very high speeds, generating a small but continuous thrust. Unlike chemical rockets that produce large amounts of thrust for short periods, ion engines operate for months or even years, providing a very gentle push. This high exhaust velocity means that ion engines are extremely fuel-efficient, allowing spacecraft to achieve significant changes in velocity with much less propellant than would be needed with chemical rockets. The thrust produced by an ion engine is very low, often compared to the weight of a piece of paper. However, over extended periods, this constant acceleration can achieve very high speeds. This makes ion propulsion ideal for long-duration missions, such as deep space exploration and station-keeping for satellites, where fuel efficiency is paramount. Key components of an ion thruster include a thrust chamber, an ionization system, and an accelerator grid. The propellant is introduced into the thrust chamber, where it is ionized. The charged ions are then accelerated through an electric field created by a series of grids, and expelled from the engine.
