Giovanni Domenico Cassini/Discovered
By 1671, Cassini was director of the Observatoire de Paris and two years later became a French citizen, changing his name to Jean-Dominique. He discovered Saturn’s moons: Iapetus in 1671, Rhea in 1672, and both Tethys and Dione in 1684.
What is named after Cassini?
The Saturn orbiter is named after Jean-Domenique Cassini, who discovered the Saturnian satellites Lapetus in 1671, Rhea in 1672, and both Tethys and Dione in 1684. In 1675 he discovered what is known today as the ‘Cassini Division’, the narrow gap separating Saturn’s rings into two parts.

How did Giovanni Cassini benefit the world?
An Italian astronomer, engineer, and astrologer, Cassini made many valuable contributions to modern science. However, it was his discovery of the gaps in Saturn’s rings and four of its largest moons for which he is most remembered, and the reason why the Cassini spacecraft bears his name.
Did Huygens contaminate Titan?
In 2005 the lander Huygens detached from Cassini and became the first spacecraft to land on Titan, the largest of Saturn’s moons. Diving into the depths of our solar system has taught us that our preconceptions about other celestial bodies can be overturned.
Why did NASA crash Cassini into Saturn?
Having expended almost every bit of the rocket propellant it carried to Saturn, operators deliberately plunged Cassini into the planet to ensure Saturn’s moons remain pristine for future exploration—in particular, the ice-covered, ocean-bearing moon Enceladus, but also Titan, with its intriguing pre-biotic chemistry.
When was Cassini invented?
Launched aboard a Titan IVB/Centaur on October 15, 1997, Cassini was active in space for nearly 20 years, with 13 years spent orbiting Saturn and studying the planet and its system after entering orbit on July 1, 2004.
How long was Cassini supposed to last?
13 years, 76 days
The Cassini mission was meant to last three years in orbit around Saturn, and instead the spacecraft spent 13 years, 76 days, orbiting Saturn. It gave us wonders to the end.
How did Cassini’s encounter with Titan change its orbit?
In 2017, an encounter with Titan changed its orbit in such a way that, at closest approach to Saturn, it was only 3,000 km (1,900 mi) above the planet’s cloudtops, below the inner edge of the D ring. This sequence of “proximal orbits” ended when its final encounter with Titan sent the probe into Saturn’s atmosphere to be destroyed.
What was the total cost of the Cassini mission?
The total cost of this scientific exploration mission was about US$3.26 billion, including $1.4 billion for pre-launch development, $704 million for mission operations, $54 million for tracking and $422 million for the launch vehicle. The United States contributed $2.6 billion (80%), the ESA $500 million (15%), and the ASI $160 million (5%).
When did Giovanni Domenico Cassini get French citizenship?
The country turned out to be considerably smaller than expected, and the king quipped that Cassini had taken more of his kingdom from him than he had won in all his wars. On 14 July 1673 Cassini obtained the benefits of French citizenship. In 1674 he married Geneviève de Laistre, the daughter of the lieutenant general of the comté of Clermont.
What did Giovanni Cassini discover about the Rings of Saturn?
Cassini discovered four satellites of the planet Saturn and noted the division of the rings of Saturn; the Cassini Division was named after him. Giovanni Domenico Cassini was also the first of his family to begin work on the project of creating a topographic map of France.
