President Trump has said repeatedly that he wants a Space Force. Congress denied the request for a new branch of the military in the latest funding bill, but some have started pricing it out, including the Center for Strategic and International Studies. Todd Harrison is director of the Aerospace Security Project there. He broke it down into three models: a Space Corps within the Air Force, Space Force Lite, and Space Force Heavy. All would mostly use existing military resources but require an additional $1.5 to $2.7 billion over five years. Harrison talks about his cost estimates with Marketplace Tech guest host Kimberly Adams.
