<P> On February 3 , 2010 , NASA announced another extension for Cassini , lasting 6 ​ ⁄ years until 2017 , ending at the time of summer solstice in Saturn 's northern hemisphere ( Cassini Solstice Mission ) . The extension enabled another 155 revolutions around the planet , 54 flybys of Titan and 11 flybys of Enceladus . In 2017 , an encounter with Titan changed its orbit in such a way that , at closest approach to Saturn , it was only 3,000 km above the planet 's cloudtops , below the inner edge of the D ring . This sequence of `` proximal orbits '' ended when its final encounter with Titan sent the probe into Saturn 's atmosphere to be destroyed . </P>
