Caption NASA:"NASA's Cassini Spacecraft successfully completed its Oct. 1st Fly-By of Saturn's moon Enceladus and its Jets of Water Vapor and Ice. At its closest approach, the Spacecraft flew approx. 62 miles (about 100 Km) above the moon's Surface. The close approach was designed to give some of Cassini's instruments, including the Ion and Neutral Mass Spectrometer, the chance to "taste" the Jets themselves.
At a higher vantage point during the encounter, Cassini's high-resolution camera captured pictures of the jets emanating from the moon's South Polar Region. The latest raw images of Enceladus are online at:

The images of the Surface include previously seen Leading-Hemisphere Terrain. However, during this encounter, multi-spectral imaging of these Terrains extended farther into the UV Region of the Spectrum than had previously been achieved at this resolution.
By looking at the Surface at UV wavelengths, scientists can better detect the difference between surface materials and shadows than they can at visible wavelengths, where icy materials are highly reflective and shadows are washed out. With both UV and Visible Light images of the same Terrain available to them, scientists will better understand how the Surface coverage of icy particles coming from the Vents and Plumes changes with Terrain type and age. Cassini's next pass of this fascinating moon will be Oct. 19, 2011, when the Spacecraft shall fly-by at an altitude of approximately 765 miles (such as about 1231 Km)".
