An informal chat and book-signing with Alan Stern, principal investigator of the New Horizons mission to Pluto, and co-author of "Chasing New Horizons: Inside the Epic First Mission to Pluto." Dr. Alan Stern is a planetary scientist, space program executive, aerospace consultant, and author. He leads NASA’s $880M New Horizons mission that successfully explored the Pluto system and is now exploring the Kuiper Belt—the farthest exploration in the history of humankind.In both 2007 and 2016, he was named on the Time 100 list. In 2007 and 2008, Dr. Stern served as NASA’s chief of all space and Earth science programs, directing a $4.4B organization with 93 separate flight missions and a program of over 3,000 research grants. During his NASA tenure, a record 10 major new flight projects were started and deep reforms of NASA’s scientific research and the education and public outreach programs were put in place. His tenure was notable for an emphasis on cost control in NASA flight missions that resulted in a 63% decrease in cost overruns.
