Voyager 2 reached Uranus on January 24, 1986, and Neptune on August 25, 1989. With the Neptune flyby, the probe turned south and achieved [[escape speed]]. Voyager 2 is now flying out of the [[solar system]], headed 48 degrees "south" at a speed of 470 million kilometers per year.<ref name=Angrum/>
The mission of Voyager 2 continues to this day (July 2, 2008) and is expected to continue for at least another decade.<ref name=Angrum/><ref name=Leech/> Voyager 2 crossed the heliosheath, or termination shock, on August 30, 2007 and thus joined Voyager 1 as one of two vessels returning data from interstellar space.<ref name=release1>"[httphttps://www.nasa.gov/mission_pages/voyager/termination_shock.html Voyager 2 Proves the Solar System is Squashed]."
