The New Horizons probe has almost reached Pluto after travelling 3 billion miles over a period of 10 years.
The spaceship is flying past the dwarf planet at 30,000 mph gathering information about the edge of the Solar System.
It'll be the first time that we'll be able to see what the icy surface of Pluto looks like.
Ayshah has been finding out a bit more about the special mission.
