		Cassini's instrumentation consists of: a synthetic aperture RADAR mapper, a CCD imaging system, a visible/infrared mapping spectrometer, a composite infrared spectrometer, a cosmic dust analyzer, a radio and plasma wave experiment, a plasma spectrometer, an ultraviolet imaging spectrograph, a magnetospheric imaging instrument, a magnetometer, an ion/neutral mass spectrometer.

		Cassini interpreted this as a glorification of is chief Louis XIV., so maybe this was the reason that it lasted twelve years before Cassini still as the director of the Paris observatory announced the discovery of two more moons of Saturn: Dione and Tethys.
		In the meantime in 1675 Cassini was able to sign also for the discovery of the main 4450 kilometer gap within the Saturn rings, the Cassini division.
		Another discovery of Cassini is the zodiacal light, an exaterristical sky illumination on the ecliptic plane caused by interplanetary dust and the reflected sunlight within the dust.

		In 1650, Cassini became professor of mathematics and astronomy at the University of Bologna, filling the chair which had been vacant since the death of Cavalieri at the end of November 1647.
		Cassini's tables of Jupiter's moons were used to determine longitudes by providing a universal time with which to compare the local time at various positions on the Earth.
		Cassini's health began to deteriorate, in particular his eyesight became poor so that by 1711 he was nearly completely blind.

		Jean-Dominique Cassini (born Giovanni Cassini) a leading astronmer, mathematician, and engineer, began his scientific career at the Panzano Observatory in Bologna, Italy, in the middle of the 17th century.
		It was Cassini who discovered the large gap in Saturn’s rings (through which the Cassini spacecraft flew on June 30, 2004, as it entered into orbit) and four of Saturn’s moons: Iapetus, Rhea, Tethy, and Dione.
		Cassini’s other accomplisments in astronomy included measuring the period of rotation in Mars and Jupiter, analyzing the orbits of Jupiter’s moons, and mapping features on the surface of the moon.

	Cassini, Giovanni Domenico (1625-1712)
		Cassini became Professor of Astronomy at Bologna (1650) and later the first director of the Paris Observatory (1669), found the rotational periods of Mars and Jupiter, one of the polar caps of Mars (1666), and the distance to Mars (1672) by triangulation with the help of observations by Jean Richer.
		His refinement of the scale of the solar system led to a value of the astronomical unit only 7% short of that accepted today.
		Cassini’s son, Jacques (1677-1756), grandson Cesar Francois (1714-1784), and great-grandson Jean Dominique IV (1748-1845) all became successful astronomers, the first two succeeding the elder Cassini as director of the Paris Observatory.
