As seen on #Cosmos: Communicating with the Cosmos. Our Deep Space Network. The DSN supports NASA and non-NASA missions that explore the furthest points of our solar system. The DSN has three ground stations located approximately 120 degrees apart on Earth (120 + 120 + 120 = 360). This is to ensure that any satellite in deep space is able to communicate with at least one station at all times. The ground stations also communicate with satellites in order to initiate course corrections, provide software updates, and alter the way scientific observations are made.
