It is not possible to launch a spacecraft as massive as Cassini/Huygens with sufficient energy to reach Saturn directly, so it will gain energy en-route by flying close to other planets to receive assists from their gravitational fields. Two flybys of Venus, one of Earth and one of Jupiter will be made, with the precise approaches ensured by intermediate corrections using the spacecraft's thrusters.
