Enceladus’ intriguing south-polar jets are noticed from afar, backlit by object while a moon itself glows gently in reflected Saturn-shine.


Observations of a jets taken from several observation geometries yield opposite insights into these conspicuous features. Cassini has collected a resources of information in a hopes of unraveling a mysteries of a subsurface sea that lurks underneath a moon’s icy crust.

This perspective looks toward a Saturn-facing hemisphere of Enceladus (313 miles or 504 kilometers across). North is up. The picture was taken in manifest light with a Cassini booster narrow-angle camera on Apr 13, 2017.

The perspective was acquired during a stretch of approximately 502,000 miles (808,000 kilometers) from Enceladus and during a sun-Enceladus-spacecraft, or phase, angle of 176 degrees. Image scale is 3 miles (5 kilometers) per pixel.

The Cassini goal is a mild plan of NASA, ESA (the European Space Agency) and a Italian Space Agency. The Jet Propulsion Laboratory, a multiplication of a California Institute of Technology in Pasadena, manages a goal for NASA’s Science Mission Directorate, Washington. The Cassini orbiter and a dual onboard cameras were designed, grown and fabricated during JPL. The imaging operations core is formed during a Space Science Institute in Boulder, Colorado.
