NASA’s Mission to Pluto was a two-part televised science event at NASA headquarters on August 25 – the same date that the agency’s New Horizons spacecraft passed the orbit of Neptune on its way to Pluto and exactly 25 years after the Voyager spacecraft’s encounter with Neptune in 1989. During the first event, entitled NASA’s New Horizons Pluto Mission: Continuing Voyager’s Legacy of Exploration, NASA scientists, and officials discussed the two missions.
