Cassini-Huygens mission is an interplanetary robotic joint NASA / ESA / ASI, launched on October 15, 1997, with the task of studying the Saturn system, including its moons and its rings. The probe consists of two elements: the Cassini orbiter from NASA and the ESA Huygens lander.
Cassini is the first spacecraft to be entered orbit around Saturn on 1 July 2004 (time 04:12 AM GMT), and only the fourth one to have visited (before Cassini had already passed the Pioneer 11 and Voyagers 1 and 2 ). On December 25, 2004 the Huygens probe was separated from the mother ship and headed toward the main moon of Saturn, Titan. On January 14, 2005 Huygens descended into the atmosphere of the satellite during the race and collected data on the atmosphere, images of the surface noise from the surroundings. He hit the ground after 2 h 30 m, and continued to broadcast its signal for another three hours.
The Cassini orbiter was named by the astronomer Gian Domenico Cassini, Italian that towards the end of 1600, played a major role in the study of Saturn and its rings. The Huygens lander is named after the Dutch seventeenth century by the astronomer Christiaan Huygens who discovered Titan using your telescope.
