CICLOPS: Cassini Imaging Central Laboratory for OPerationS

A Scene of Craters
[For trouble viewing the images/movies on this page, go here]
This high-resolution view shows a vast range of crater sizes in the dark terrain of Iapetus' leading hemisphere.

Across the scene, a few small bright spots indicate fresh, rayed craters where impactors have punched through the thin blanket of dark material to the cleaner ice beneath.

The slight elevation on the bottom half of the image is part of the giant equatorial ridge that spans a wide fraction of Iapetus' circumference. The numerous craters on top of the ridge indicate that it is an old surface feature.

The mosaic consists of three image footprints across the surface of Iapetus. The view is centered on terrain near 0.5 degrees north latitude, 141.6 degrees west longitude. Image scale is approximately 22 meters (72 feet) per pixel. Illumination is from left.

The clear spectral filter images in this mosaic were obtained with the Cassini spacecraft narrow angle camera on Sept. 10, 2007 at a distance of approximately 63,000 kilometers (39,000 miles) from Iapetus and at a Sun-Iapetus-spacecraft, or phase, angle of about 125 degrees.

Iapetus is 1,471 kilometers (914 miles) across.

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 Cassini-Huygens mission for NASA's Science Mission Directorate, Washington, D.C. The imaging team consists of scientists from the US, England, France, and Germany. The imaging operations center and team lead (Dr. C. Porco) are based at the Space Science Institute in Boulder, Colo.

lower-case letters have a specific value that i can understand and answer

IN REGARD TO LOWER-CASE LETTERS IS A MEANS OF COMMUNICTIONS THAT WE HAVE ADOPTED FOR INSTANCE responce WOULD HAVE A SPECIFIC VALUE THAT I COULD respond to or answer

Umm... What are your thoughts on the concept of lower-case letters?

THE MOONS OF SATURN ARE ASTONISTING AREAS THAT ONE DAY WITH HOPE PEOPLE WILL HAVE SETTLED WITH GODS HELP THE WARS CAN END AND WITH A GOLBAL EFORT WE CAN DO IT

Looks like the Godz had a huge battle here, throwing projectiles into the armour like surface of Iapetus until it looks like this image resembling heavily pitted metal bunker armour that I've seen in old WW2 photo's. I checked Wikpedia and the surface is not partially metallic like I was thinking, but is mostly ice. The heat of impacts melting the ice like shell impacts melting metal on armour ?
