Enceladus, Janus and Dione Rev 163 Raw Preview

These raw, unprocessed images of Saturn's moons Enceladus, Janus and Dione were taken on March 27 and 28, 2012, by NASA's Cassini spacecraft.

Cassini passed Enceladus first on March 27, coming within about 46 miles (74 kilometers) of the moon's surface. The encounter was primarily designed for Cassini's ion and neutral mass spectrometer, which "tasted" the composition of Enceladus' south polar plume. Other instruments, including the Cassini plasma spectrometer and composite infrared spectrometer, also took measurements.

Before the closest approach of this encounter, Cassini's cameras imaged the plume which is comprised of jets of water ice and vapor, and organic compounds emanating from the south polar region. Later the cameras captured a nine-frame mosaic of the surface of the moon's leading hemisphere as the spacecraft left the moon.

After the Enceladus encounter, Cassini passed the small moon Janus with a closest approach distance of 27,000 miles (44,000 kilometers). The planet was in the background in some of these views.

Early on March 28, the spacecraft flew by Dione at a distance of 27,000 miles (44,000 kilometers) and collected, among other observations, a nine-frame mosaic depicting the side of the moon that faces away from Saturn in its orbit.

So are we talking spicules here? Sodium...sounds like you're setting up conditions for the Miller-Urey experiment...Why not turn Cassini's gaze toward the interior of Saturn, Titan or Hyperion...so pretty! All hail liquid metallic Hydrogen!

God must have used science for the immaculate conception...But so many people have foregone God to get to science...?

Is there an "11" for those fountain pics?!? That moon has been exciting, enticing and awesome from day one.
