The Department of the Defense said Friday that it will investigate the reasons why the Space Command headquarters were moved to Huntsville, Ala., instead of Colorado Springs. The agency’s Office of Inspector General said in a memorandum that the investigation will focus on three main points: whether the move followed Department of Defense and Air Force policies, whether “objective and relevant scoring factors” were used to rank the locations and whether the costs “and other scoring factors” were accurate and consistent. Originally, the Space Command headquarters was supposed to be in Colorado Springs.
