This week’s episode is about U.S. Space Force doctrine, the Secretary of the Air Force’s email signaling big changes ahead, and the new nine-word-long mission statement: “secure our Nation’s interests in, from, and to space.” Laura Winter discusses these developments and what they mean for the future of the Space Force with Peter Garretson, a senior fellow at the American Foreign Policy Council and co-author of the book “The Next Space Race: A Blueprint for American Primacy”; and Brent Ziarnick, an associate professor of Space Power at Johns Hopkins School of Advanced International Studies, and author of the book “Developing National Power in Space: A Theoretical Model”.
