8.1.10 New Horizons Pluto–Charon flyby
In July 2015 the New Horizons mission flew close past Pluto and Charon – its destination after almost a decade in flight. New Horizons explored the Pluto–Charon system and provided more detail than ever seen before, though it did not find any new moons.
When it was at Pluto, the radio signal that it used to send its data back to Earth took about 3.5 hours to reach us, travelling at the speed of light. New Horizons passed close to Jupiter en route, sending back pictures of Io’s erupting volcanoes.
This NASA video was released in 2011, so when the narrator says that New Horizons ‘still has four more years of travel to go’, he is out of date. Also, it did not stop when it reached Pluto! It will continue outwards, and if it remains in good health it may be possible to achieve more distant flybys past one or two other, more distant, Kuiper Belt objects (which may or may not prove to have moons of their own).
