  Calypso (moon) - Encyclopedia, History, Geography and Biography
Calypso (kə-lip'-soe, IPA /kəˈlɪpso/, Greek Καλυψώ) is a moon of Saturn.
The moon Telesto resides in Tethys' leading Lagrangian point, 60 degrees ahead of Tethys.
Like many other small Saturnian moons and small asteroids it is irregularly shaped by overlapping large craters and appears to also have loose surface material capable of smoothing the appearance of craters.

 Pallene (moon) - Wikipedia, the free encyclopedia
Pallene (pə-lee'-nee, IPA: [pəˈliːni], Greek Παλλήνη) is a very small natural satellite of Saturn lying between the orbits of Mimas and Enceladus.
Pallene is visibly affected by a perturbing mean longitude resonance with the much larger Enceladus, although this effect is not as large as the Mimas perturbations on Methone.
Pallene was one of the Alkyonides, the seven beautiful daughters of the Giant Alkyoneus.

 Phoebe (moon) - Encyclopedia, History, Geography and Biography
Phoebe (fee'-bee, IPA /ˈfiːbi/, Greek Φοίβη) is a moon of Saturn.
The outer moons can be broken down into two groups: Siarnaq's group (Kiviuq, Ijiraq, Paaliaq, Albiorix, Erriapo, Siarnaq and Tarvos) is inclined 33.5-46.5° whilst Phoebe's group (Phoebe, Skathi, Narvi, Mundilfari, Suttungr, Thrymr and Ymir) is retrograde and inclined 134.5-175.5°.
Both groups are fairly to highly eccentric, and none of their moons are expected to rotate synchronously as all the inner moons of Saturn do (except for Hyperion).

 Saturn: Jewel of the Solar System
Of course, new moons around the outer planets are continually being discovered as spacecraft approach and instrumentation is refined.
But Saturn does have “proper” moons that are large, round, and, well, moonlike: There’s Enceladus, whose highly reflective surface may be covered in ice; Iapetus, an enigma with one bright and one dark face; Mimas, with its huge impact crater telling of a long-ago cataclysm.
It might seem compelling to reserve the title “moon” for objects with rounded profiles, but again, we have no system for determining when a body is too lumpy to be called a moon.

The new Pallene ring is a faint narrow band, about 2,500 kilometers (about 1,550 miles) across, between the E ring and the G ring.
Pallene, discovered by Cassini's imaging cameras earlier in the mission, is 4 kilometers (2.5 miles) across.
Pallene orbits Saturn between the moons Mimas and Enceladus.

Moons around gas giants are typically more active, and warmer than one might otherwise expect, because of the significant tidal forces and magnetic disruption produced by orbiting such large bodies so closely.
Analysis of the outgassing suggests that it originates from a body of sub-surface liquid water, which along with the unique chemistry found in the plume, has fueled speculations that Enceladus may be important in the study of astrobiology.
The moon is depicted as having an atmosphere and supporting a happy population of humanoid life.

 NASA's Solar System Exploration: Planets: Saturn: Moons: Pallene
The moons were first seen by Dr. Sebastien Charnoz, a planetary dynamicist working with Dr. Andre Brahic, imaging team member at the University of Paris.
Scientists expected that moons as small as S/2004 S1 and S/2004 S2 might be found within gaps in the rings and perhaps near the F ring, so they were surprised these small bodies are between two major moons.
The fact that these moons exist where they do might provide limits on the number of small comets in the outer solar system, a quantity essential for understanding the Kuiper Belt of comets beyond Neptune, and the cratering histories of the moons of the giant planets.

This latter object is an example of a so-called Trojan moon - it is twinned with a larger satellite in orbit around the planet.
Trojan moons are found near stable "Lagrange points" - places where the gravitational pull of the planet and the larger satellite become balanced.
The Trojans are situated 60 degrees ahead or behind the larger moon in its orbit (in the case of Polydeuces, the larger moon is Dione).

Unlike most major moons orbiting Saturn, Phoebe is very dark and reflects only 6 percent of the sunlight it receives.
Phoebe's darkness, in particular, suggests that the small moon comes from the outer solar system, an area where there is plenty of dark material.

 Saturn's Moons May Be Creating New Rings - Planetary News | The Planetary Society
The new rings are associated with one or more small moons and share their orbits with the moons, while scientists suspect a moon is lurking near a third ring.
It is narrow and overlies the orbit of the tiny moon Pallene, which Cassini discovered back in 2004.
When these moons are struck by rapidly moving interplanetary meteoroids, this loose material is blasted off their surfaces and into Saturn orbit, creating diffuse rings along the moons' orbital paths.

Cassini scientists are on the trail of the missing moons of Saturn.
The moon Enceladus is seen sweeping through the E ring, extending wispy, fingerlike projections into the ring.
The moon is cloaked in a thick, smog-like haze that scientists believe may be very similar to Earth's before life began more than 3.8 billion years ago.

The tiny moon orbiting Saturn named Enceladus has become the third body in the solar system known to have current volcanic activity driven by internal heating, after Earth and Jupiter's moon Io.
By the time Cassini had passed the small moon it had come to within 172 km (107 miles) of the surface, the closest flyby yet in a 4-year mission to tour and collect data about the Saturnian system.
Enceladus, a tiny moon of Saturn, may be a world of water ice volcanoes actively resurfacing the surrounding terrain, according to planetary scientists.

 Athena
She was somewhat known as a giant-killer, starting with the strangely misnamed goat-giant Pallas; the story of her killing and flaying of this giant was a late explanation for the ancient worship of her in Pallene.
The Graea and the Gorgons were sometimes considered Moon trinities which were associated with her, and Athena even absorbed a few of their associated totems, such as the swan.
Her version of the crone was oddly similar to the Cailleach 'veiled one' of Celtic lands, who had blue-fl skin and one bright, glowing eye, personifying the Moon in the sky, as Hera did its starry regions when she wore her peacock feather robes during her time as prophetic crone.

Temporarily dubbed S/2004 S7 through S/2004 S18, the moons were first seen in December 2004, but the astronomers observed them for the first few months of 2005 with a variety of powerful telescopes before announcing their find.
Polydeuces is interesting because it’s a Trojan moon, a moon that travels in the same orbit as a larger moon, either 60 degrees ahead of it or behind it.
Scientists think that other small moons will be found in gaps between the rings, and they plan, in particular, for Cassini to go moon hunting in the area between the A Ring and the F Ring.

Trojan Moons are not named so much for their relationship to Troy, but rather take their name from the unique mathematical nature of their orbits in relation to one another.

 More from Saturn - including the discovery of a "Trojan" moon
Trojan moons are those found near stable "Lagrange points" (see "Notes to Editors") and are situated 60 degrees ahead or behind a larger moon in its orbit around a planet.
The term "Trojan moons" comes from the example of Trojan asteroids that are in the same orbit as Jupiter.
If there is a central planet with a moon in orbit around it then there are five special points (the Lagrange points) where the gravitational effects of the planet and moon are balanced.

 Discovery Channel :: News - Animals :: Backlit Saturn Shows New Moons, Rings
Scientists believe the rings are dust particles caused by asteroids or comets striking the surfaces of small inner moons circling Saturn.
The moons' gravity is too weak to hold on to any kind of surface dust, so impacts blast material into Saturn's orbit, where the particles assemble into loosely packed rings in the moons' orbital paths.
Oddly, a similarly sized moon named Methone, previously discovered near Pallene, does not seem to have spawned a ring, the Cassini team found.

These moons were chosen as data from previous missions suggests they could hold the keys to understanding the Saturnian system and possibly the origins of the Solar System.
At least 30 distant flybys, at altitudes of up to 100 000 kilometres, will be made of other major moons.
In turn these maps can be used in conjunction with the data returned from the Huygens probe to help build up a three-dimensional picture of Titan's surface and atmosphere.
