The main body of the spacecraft is made by special aluminum, three vortex triangle shaped, but this could not be the definitive format; studies have been carried to determine a final shape in order to optimize the physical structure and therefore maintain a desirable amount of energy being delivered by these, to keep the satellite in operational condition.
