Cassini was named for the French astronomer Gian Domenico Cassini, who discovered four of Saturn's moons and the Cassini division, a large gap in Saturn's rings. Huygens was named for the Dutch scientist Christiaan Huygens, who discovered Saturn's rings and Titan.

How many moons were discovered by Cassini?
Discovering multiple moons Excluding Saturn's ice- and rock-filled rings, the planet hosts 53 known moons and eight provisional (unconfirmed) moons, according to NASA. The mind-blowing thing is that when the mission began in 1997, scientists only knew of 18 moons around Saturn.
What moons did Cassini-Huygens discover?
Cassini was the first dedicated spacecraft to look at Saturn and its system. It was named for Giovanni Cassini, a 17th-century astronomer who was the first to observe four of Saturn's moons — Iapetus (1671), Rhea (1672), Tethys (1684) and Dione (1684).
Is Huygens still on Titan?
In 2005, the Huygens probe pierced the shroud of Saturn's moon Titan to reveal a surprisingly Earth-like world. The Huygens probe became — and thus far remains — the most distant human-made landing craft when it touched down on Titan's surface in 2005.
Why did NASA destroy Cassini?
The mission ended on September 15, 2017, when Cassini's trajectory took it into Saturn's upper atmosphere and it burned up in order to prevent any risk of contaminating Saturn's moons, which might have offered habitable environments to stowaway terrestrial microbes on the spacecraft.

What did Cassini discover in the rings of Saturn?
Cassini captured extraordinary ring-moon interactions, observed the lowest ring-temperature ever recorded at Saturn, discovered that the moon Enceladus is the source for Saturn's E ring, and viewed the rings at equinox when sunlight strikes the rings edge-on, revealing never-before-seen ring features and details.

How many moons Saturn have?
82 moons Saturn has 82 moons. Fifty-three moons are confirmed and named and another 29 moons are awaiting confirmation of discovery and official naming. Saturn's moons range in size from larger than the planet Mercury — the giant moon Titan — to as small as a sports arena.
How long did Huygens last?
On Christmas Day 2004 at 02:00 UT, the Huygens lander, which had remained dormant for more than six years, separated from Cassini and began its 22-day coast to Titan. It entered Titan's atmosphere at 09:05:56 UT Jan.
