Cassini has completed another close reconnaissance pass of one of Saturn’s most intriguing moons; Enceladus. On November 2nd at 7:40 AM UTC, Cassini passed 62 miles above the icy surface of the south polar region, completing a carefully timed plunge through one of its liquid plumes. This was one of its most comprehensive passes of the moon out of the seven completed so far, enabling the spacecraft to utilize its array of infrared and ultraviolet detectors to analyze speed and particle size. Cassini itself is whizzing along at 5 miles per second. Sodium, water, and carbon dioxide have been detected in the out-gassing, tantalizing evidence that more complex organic chemistry may exist below the surface. Enceladus is heated from tidal flexing caused by Saturn’s gravity squeezing it like a rubber ball. Along with Jupiter’s moon, Europa, Enceladus has been proposed as deserving of future scrutiny as a possible abode of life. Enceladus is a tiny world, about 310 miles in diameter, or about 15% the diameter of our Moon. Two subsurface oceans in one solar system also poses the intriguing question; are environments like Enceladus and Europa more common throughout the universe than Earth? Cassini has phoned home after the recent pass and is reported in good health. Scientists are currently poring over the results; watch for another pass of Enceladus on April 28th of next year. What ever the outcome, Enceladus is proving to be a dynamic place, worthy of future study!
