NASA’s New Horizons probe is four billion miles away. It took the first pictures ever of Pluto and is now sending back lots of information about things far beyond Pluto. The new discoveries of the dwarf planet also bring new questions. Alan Stern is the principal investigator of the New Horizons Mission at NASA. (Originally aired Jan 29, 2020).
