Orbiting the ringed planet Saturn and its numerous moons, the Cassini spacecraft had been a keystone of exploration of the Saturnian system and the properties of gaseous planets in our solar system. Gian Domenico Cassini, French Jean-Dominique Cassini, (born June 8, 1625, Perinaldo, Republic of Genoa [Italy]—died September 14, 1712, Paris, France), Italian-born French astronomer who, among others, discovered the Cassini Division, the dark gap between the rings A and B of Saturn; he also discovered four of Saturn's moons.In addition, he was the first to record observations of the . The 22ft long spacecraft, launched from Cape Canaveral, Florida, in 1997, took seven years to reach Saturn. The spacecraft discovered propeller-like formations, witnessed the possible birth of a new moon and observed what may be one of the most active, chaotic rings in our solar system (Saturn's F ring). No further discoveries of significance were made until 1789 when William Herschel discovered two further moons, Mimas and Enceladus. Thus, Saturn's biggest mission and gap were named after him. He shares with Robert Hooke credit for the discovery of the Great Red Spot on Jupiter, circa 1665. Cassini showed us the complexity of Saturn's rings and the dramatic processes operating within them. Their analysis suggests it is possible for liquid water to reach from the moon's underground sea all the way to its surface. Giovanni Cassini was a 17th century Italian mathematician, astronomer and astrologer, most famous for discovering four satellites of the planet Saturn. The Cassini Spacecraft sent its final images to Earth as the probe plunged into Saturn's rings. The spacecraft launched nearly 20 years ago, and took about seven years to make it to Saturn's orbit. Thus, Saturn's biggest mission and gap were named after him. Answer (1 of 3): I haven't been able to find the amounts of fuel, but there were two systems. Obviously, it was also known to the ancient Greeks and the Romans. (The Voyager probes and the Pioneer 11 probe had all made short flybys of Saturn prior to Cassini's . Answer (1 of 10): Saturn was known to prehistoric observers, and its movements in the sky (distinguishing it as a planet from ordinary stars) were recorded by ancient Babylonian astronomers from around 3500BC.
