beskrivelse:

This raw, unprocessed image of Saturn's moon Helene was taken by Cassini on 18. juni 2011 and received on Earth 20. juni 2011.

Helene is a trojan moon of Dione. It leads Dione by 60 degrees in their shared orbit. The view looks toward the leading hemisphere of Helene (33 kilometers, 21 miles across). North on Helene is towards the top.

The camera was pointing toward Helene, and the image was taken using the CL1 and CL2 filters. The image has not been validated or calibrated. A validated/calibrated image will be archived with the Planetary Data System in 2012.

The Cassini Solstice Mission is a joint United States and European endeavor. The Jet Propulsion Laboratory (JPL), 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 was designed, developed and assembled at JPL. 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, Colorado.
