NASA’s New Horizons Team Discusses Discoveries from the Kuiper Belt
New Horizons team members shared several discoveries with media on March 14 at the 54th Lunar and Planetary Science Conference. Among them: new clues to the origins of Arrokoth, new findings about ancient and evolving geology of Pluto, and a preview of Uranus and Neptune observations that could improve our knowledge of those worlds and influence how we interpret data on similar planets in other solar systems.
