Cassini is NASA's latest Planetary Explorer. Just now arriving at Saturn, this spacecraft will carry out an even more extensive examination of the Saturnian environment than Galileo did of the Jovian environment. This excellent spacecraft is based on Jack Higgins' superb Cassini rendition and for the first time has been mated to its launch vehicle. Cassini requires the most advanced trajectory of any of these addons, the Venus Venus Earth Jupiter Gravity Assist (VVEGA).
Be sure to be watching June 30-July 1st as Cassini Rendezvous with Saturn and again at Christmas for Huygens descent into Titan!
