An ionic mini motor, weighing only 7 oz, will allow the new generation of nanosatellites to have autonomous capabilities and "set them free" from their current orbits. The tiny motor will include fuel and electronics and will be attached to satellites as small as a 4 inch cube. It will use an ionic liquid, the chemical compound EMI-BF4, from which ions with electrical charges will be extracted and then ejected to provide thrust. Although the motor will only provide a tiny...
