Key Takeaways:
- New Horizons successfully flew by Pluto in 2015.
- It mapped Pluto's surface and studied its atmosphere and moons.
- Data suggests Pluto may have an underground ocean.
- The spacecraft continues its journey into interstellar space.
New Horizons launched in January 2006, and by July 14, 2015, it had reached its primary goal: Pluto. The first spacecraft to study Pluto up close, it conducted measurements of Pluto’s atmosphere, mapped the surface geology, observed Pluto’s moons. New Horizons also investigated the dwarf planet’s interior structure, adding support to the theory that Pluto has a subsurface ocean. The mountains of data collected at Pluto continue to be analyzed and researched today, while the spacecraft itself is in the Kuiper Belt, on a trajectory for interstellar space.
