This is the highest resolution image yet taken of Saturn's moon Telesto, which shares its orbital path with the much larger moon Tethys. Telesto is 24 kilometers (15 miles) across. <br /><br />Telesto has a potato-like shape. Overall the surface appears to be fairly smooth with a number of craters present. <br /><br />The image was taken with the Cassini spacecraft narrow-angle camera on October 11, 2005, at a distance of approximately 10,424 kilometers from Telesto. <br /> <div class="Discussion_UserSignature"> <p><font color="#000080">"I suddenly noticed an anomaly to the left of Io, just off the rim of that world.

Interesting shot of Telesto's creamy-smooth surface. I would say this particular object is young. IMHO, it is made out of snow from Enceladus' geysers. I don't think this is one of the original Lagrangians that formed with Tethys. That would be Odysseus crater.

 

[3488]

I have wondered about that too. Telesto is Lagrangian with Tethys in the forward position. Telesto is only slightly larger than the Mars moon Phobos, yet if Phobos was seen at this high resolution, it would be covered in craters. The large ice boulders show that the ice is pretty hard in places, not just fluffy like snow, although the surface is covered in a layer of ice crystals much like snow (about minus 185 Celsius, much colder than any ice on Earth or Mars)<br /><br />I would assusme that Telesto keeps the longest axis turned towards Saturn??<br /><br />Telesto likely formed from icy material that collected in a 'Pool' of icy material in the forward Lagrangian point. The smooth surface could well be from the ice geysers of Enceladus, as the Jupiter moons Amalthea & Thebe are red due to the sulphur from the volcanoes of Io. <div class="Discussion_UserSignature"> <p><font color="#000080">"I suddenly noticed an anomaly to the left of Io, just off the rim of that world.

Cassini takes in a wide-angle view of majestic, golden-hued Saturn ... home to our robotic spacecraft for two years now. The ringplane cuts across the center of Saturn's crescent which wears shadows cast by the icy rings. <br /><br />The planet's now familiar blue and pink hues generally are more subtle in high-phase views from the Cassini wide-angle camera. "Phase" refers to the angle formed between the Sun, the planet and the spacecraft. <br /><br />The view is a composite of two sets of color images taken using red, green and blue spectral filters. The images were combined to create a color view that approximates the scene as it might appear to human eyes. <br /><br />The images were taken with the Cassini spacecraft wide-angle camera on May 24, 2006 at a distance of approximately 1.3 million kilometers (824,000 miles) from Saturn and at a Sun-Saturn-spacecraft, or phase, angle of 139 degrees. Image scale is 76 kilometers (47 miles) per pixel. <br /><br />The Cassini-Huygens mission is a cooperative project of NASA, the European Space Agency and the Italian Space Agency. The Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena, manages the mission for NASA's Science Mission Directorate, Washington, D.C. The Cassini orbiter and its two onboard cameras were designed, developed and assembled at JPL. The imaging operations center is based at the Space Science Institute in Boulder, Colo. <br /><br />For more information about the Cassini-Huygens mission visit http://saturn.jpl.nasa.gov/home/index.cfm.

Saturday 29th April 2006. Saturn's small, ice, walnut-shaped moon, Pan, embedded in the planet's rings, as seen by the Cassini Spacecraft. <br /><br />Pan (26 kilometers, or 16 miles across) and the rings against the night side of Saturn. Pan here is towards the outside edge, or ansa, of the Encke Gap (325 kilometers, or 200 miles wide) in which it orbits. Saturn's dark shadow is seen stretching across the middle of the ringplane.<br /> <div class="Discussion_UserSignature"> <p><font color="#000080">"I suddenly noticed an anomaly to the left of Io, just off the rim of that world.

This close pairing of Janus and Epimetheus shows the two moons at "high phase," meaning that only a thin sliver of sunlit terrain is visible on each moon. Portions of each are also lit feebly by reflected light from Saturn. <br /><br />Here, Janus (181 kilometers, or 113 miles across) is at top and Epimetheus (116 kilometers, or 72 miles across) is below. <br /><br />The image was taken in visible light with the Cassini spacecraft narrow-angle camera on Sunday, December, 25, 2005, (Christmas Day 2005) at a distance of approximately 479,000 kilometers (298,000 miles) from Janus and 455,000 kilometers (283,000 miles) from Epimetheus. The image scale is about 3 kilometers (2 miles) per pixel on both moons. <br /><br /> <div class="Discussion_UserSignature"> <p><font color="#000080">"I suddenly noticed an anomaly to the left of Io, just off the rim of that world.

Very interesting article on Saturn's embedded ring moons. link Please also see the pictures of the moons:<br />Atlas<br />close-up model of Atlas<br /><br />I think this offers support for the hypothesis that Iapetus circumferential mountains had been formed by an ancient ring accretion event.

I oif this gives some support to the idea of Iapetus acquiring it's equatorial ring through an accretion disc.<br /><br />Thanx Andrew, my Science should come today or tomorrow <img src="/images/icons/smile.gif" /> <div class="Discussion_UserSignature"> <p><font color="#000080"><em><font color="#000000">But the Krell forgot one thing John.
