United States Space Command

United States Space Command (USSPACECOM or SPACECOM) is the space service branch of the U.S. Armed Forces, one of the eight uniformed services, and the world's first independent space force. Formerly, a unified combatant command of the United States Department of Defense, responsible for military operations in outer space, specifically all operations 100 kilometers (62 miles) above mean sea level. The United States Space Command is under the Department of the Air Force and shares resources with the United States Air Force. It is headquartered at Palmdale, California, United States, where it has been stationed since 2005. The main launch facility is Vandenberg Space Command Arsenal in California, while access to any Space Command facility can be completed at Mojave Space Center. The Space Command is lead by a single four-star Admiral, known as the Commandant of Space Command. It was founded as a result of the 1998 asteroid crisis on September 13, 1999.

Space Command personnel are referred to as troopers.
