New Horizons, which passed Pluto in 2015, is on its way to new discoveries deep in the Kuiper Belt – a region inhabited by ancient remnants from the dawn of the solar system. It’ll encounter its next target, a cold, classic Kuiper Belt object called MU69, in late 2018. In the meantime, mission scientists are still poring over the data from New Horizons’ Pluto encounter, and wow! The discoveries they’re still making show Pluto – dwarf planet though it may now be – as one of the most fascinating worlds in our solar system.
Bottom line: New ScienceCast video on what’s still being learned from New Horizons’ 2015 Pluto encounter, plus a preview of the craft’s next target, MU69.
