The Titan IVB core vehicle and its twin Solid Rocket Motor Upgrades (SRMUs) which will be used to propel the Cassini spacecraft to its final destination, Saturn, arrive at the pad at Launch Complex 40, Cape Canaveral Air Station. At the pad, the Centaur upper stage will be added and, eventually, the prime payload, the Cassini spacecraft. Cassini will explore the Saturnian system, including the planet’s rings and moon, Titan. Launch of the Cassini mission to Saturn is scheduled for Oct. 6
