Astronomer and former SETI director Jill Tarter talks about the future of our planet and why she ate so many ice cream cones when she worked at NASA. Tarter’s career was the basis for Carl Sagan’s 1985 science-fiction novel, Contact, which was later made into a film starring Jodie Foster. She talks about what it’s like to have Sagan fictionalize her life, why we need to listen more than we talk, and why it’s important for us to think of ourselves as earthlings.
