Cassini spacecraft image of the north pole of Saturn's moon Enceladus. This surface, composed mainly of ice, is covered in impact craters and fractures. The joint NASA-ESA Cassini-Huygens spacecraft was launched in 1997 and took seven years to reach Saturn and its moons. The Huygens probe separated from Cassini on 25th December 2004, and descended to the surface of Saturn's largest moon, Titan. The Cassini orbiter continued orbiting Saturn; studying its atmosphere and rings and performing flybys of its moons. Image obtained by Cassini's narrow-angle camera on 14th October 2015 at an approximate distance of 6,000 kilometres from Enceladus.
