We're kicking off this new season of Military Matters with a conversation with the co-author of "Accessory to War: The Unspoken Alliance Between Astrophysics and the Military," Dr. Neil deGrasse Tyson. We discuss the intersection between science and war, why we're racing to the moon once again except this time against China, and whether humanity has learned anything about exploring and colonizing as we venture past our own solar system. This episode is brought to you by Homes For Our Troops, a nonprofit helping build and donate homes to injured post 9-11 veterans. Visit HFOTUSA.org for more information.
