This week on Planetary Radio, we celebrate the enduring legacy of Ed Stone, the longtime project scientist for NASA’s Voyager mission and former director of JPL. Mat Kaplan, senior communications advisor at The Planetary Society, takes us to the unveiling of the Dr. Edward Stone Voyager Exploration Trail at JPL, where we hear from past and present JPL leaders, Voyager mission team members, and Ed Stone’s family. Plus, we kick off the episode with the much-anticipated launch of Blue Origin’s New Glenn rocket and wrap up with What’s Up, as Bruce Betts explores the rare planetary configuration that made Voyager’s Grand Tour possible.
