Cosmonautics. Plutonium for Pluto (2015)

The spacecraft called "New Horizons" reached Pluto, photographed it from a distance of 12 thousand kilometers and went further towards the Kuiper belt on the border of the Solar System.

Scientists suggest that there may be other dwarf planets, large asteroids and comets.

Presumably, the reconnaissance probe will work in deep space for another 10 years, thanks to special batteries based on the plutonium isotope.
