1997.10.6 CASSINI probe toward Saturn took advantage of gravitation of each planet for accelerating

CASSINI probe with the weight of 56,00 kg to warding Mars was launched by Titan IVB/ Centaur launch vehicle is expected to fly by Venus, the earth, and Jupiter and gain the speed by the gravity of each planet. It is expected to arrive Saturn at 3.2 billion km away and take four years to orbit and observe Saturn.
The history of the use of gravity, on April 21, 1998, it took the advantage of Venus to Gain the first acceleration and on June 20, 1999 for the second time. Later on August 16,1999 and December 30, 2000, it used the gravitation of the earth and Jupiter respectively. And it is expected to reach to Saturn on July 1, 2004 CASSINI was equipped with 12 observation sensors and after entering the orbit of Saturn, it is expected to sail to the largest moon of Saturn, Titan, and land HUYGENS probe with the weight of 350 kg and the diameter of 2.7 m. At the same time, the exploration of Saturn, the ring of Jupiter, and magnetic field will begin. The mission is scheduled to be completed on July 1, 2008.
