Cassini sees three moons in one flyby

The Cassini orbiter has returned more vivid imagery from Saturn after collecting snapshots of three moons during a flyby Friday.

The spacecraft was aiming for a point 1,555 miles over the south pole of Enceladus, an icy moon harboring geysers spewing water vapor dozens of miles into space.

The watery plumes originate from fissures called tiger stripes in the icy crust of Enceladus, and Cassini's objective Friday was to take the temperature of the features with an infrared spectrometer.

But Cassini's narrow and wide angle cameras also captured views of Enceladus and two other moons named Tethys and Dione.

The pictures add to Cassini's growing collection of imagery taken since the probe arrived in orbit around Saturn in 2004.
