.Each Voyager probings feature three collections, or branches, of thrusters: 2 sets of attitude power thrusters as well as one set of velocity correction maneuver thrusters. In the course of the goal's earthly flybys, each sorts of thrusters were used for various purposes. However as Voyager 1 takes a trip on an unchanging road away from the solar system, its own thruster needs are simpler, and also either thruster division could be used to point the spacecraft at The planet.
