  Dione (moon) - Wikipedia, the free encyclopedia
Dione is composed primarily of water ice, but as the third densest of Saturn's moons (aside from Enceladus and Titan, whose density is increased by gravitational compression) it must have a considerable fraction of denser material like silicate rock in its interior.
One hypothesis was that shortly after its formation Dione was geologically active, and some process such as ice volcanism resurfaced much of its surface, with the streaks forming from eruptions along cracks in Dione's surface that fell back to the surface as snow or ash.
This suggests that during the period of heavy bombardment, Dione was tidally locked to Saturn in the opposite orientation.

 Dione (mythology) - Wikipedia, the free encyclopedia
Dione in Greek mythology is a vague goddess presence who has her most concrete form in Book V of Homer's Iliad as the mother of Aphrodite: Aphrodite journeys to Dione's side after she has been wounded in battle while protecting her favorite son Aeneas.
Although Dione is not a Titan in Hesiod, but appears instead in his Theogony among the long list of Oceanids, Apollodorus includes her among the Titans (1.1.3 and 1.3.1).
The archaic king Tantalus in Lydia had Dione as a consort: the Roman mythographer, Hyginus, (Fabulae 82, 83) says that Dione is a daughter of Atlas and the mother, by Tantalus, of Pelops, Niobe and Broteas.

 Dione - LoveToKnow 1911
DIONE, in the earliest Greek mythology, the wife of Zeus.
It is probable that in very early times the cult of Dione existed in Athens, where she had an altar before the Erechtheum.
Speaking generally, Dione may be regarded as the female embodiment of the attributes of Zeus, to whose name her own is related as Juno (= Jovino) to Jupiter.

 Dione
Dione's relatively high density suggests that it has a rocky core, making up about one third of its total mass, surrounded by water ice.
Contrary to what might be expected of a satellite in gravitational lock, it is the trailing hemisphere of Dione on which the majority of intense cratering exists.
The likelihood is that Dione has been tidally locked in its current state for several billion years judging by the average albedo of the leading and trailing hemispheres.

Dione is probably composed of a rocky core making up one-third of the moon's mass, and the rest is composed of water-ice.
Dione's icy surface includes heavily cratered terrain, with moderately and lightly cratered plains, as well as some severely cracked areas, with very bright material on the walls of the fractures.
This anomaly suggests that during the period of heavy meteors bombardment, Dione was tidally locked to Saturn in the opposite orientation.

 Dione
A cratering model was proposed for a tidally locked satellite with the highest cratering rates on the leading hemisphere and the lowest on the trailing hemisphere.
Because Dione is relatively small moon and an impact causing a 35 kilometer crater could have spun the satellite around.
This theory is also supported by observations of the brightess of Dione, where the average surface albedo decreases from the leading to the trailing hemispheres (The leading hemisphere is brighter).

 Discovery Channel :: News :: Saturn Moon Dione in Cassini's Sights   (Site not responding. Last check: 2007-10-23)
Discovered during a Voyager flyby three decades ago, the fissures were so prevalent that the moon looked misty, leading scientists to speculate that ice volcanoes had tapped fresh material from deep inside the moon and sprayed it across the face.
That theory ended when the Cassini spacecraft turned its cameras and sensors on Dione last October and discovered that the "mist" actually was a fine and varied network of cracks and fissures.
If that were the case, Dione would be much farther along than Enceledus, similar to how Mars may be like an older Earth, stripped of its surface water and most of its atmosphere.

 Universe Today - Cassini's Closeup View of Dione
Cassini found evidence that Dione's surface is covered by fractures, which run in roughly parallel lines; these are interrupted by larger bright features.
"Dione seems to be an older sibling of Enceladus," said Dr. Bonnie Buratti, scientist on the Cassini visual and infrared mapping spectrometer team at NASA's Jet Propulsion Laboratory, Pasadena, Calif. "We think that the cracked features of Dione may be the older version of the tiger stripes on Enceladus.
As on other Saturnian moons, rockslides on Dione may reveal cleaner ice, while the darker materials accumulate in areas of lower topography, such as crater floors and the bases of scarps.
