The goal of this electricity and electronics science fair project is to understand how ions are used to propel spacecraft in space, and to use a NASA online simulator to design your own ion engine. The Science Buddies project ideas are set up consistently beginning with an abstract, objective, and introduction, followed by a section on terms, concepts, and questions, bibliography, list of materials and equipment, experimental procedure, suggestions on how to vary the experiment, plus a focus on the sort of careers this experiment might relate to.
