  directly supports space activity terrestrially. (JP 3-14)
  space capability
  (DOD) 1. The ability of a space asset to accomplish a mission. 2. The ability of a terrestrial-based asset

  space control
  (DOD) Operations to ensure freedom of action in space for the United States and its allies and deny an
  adversary freedom of action in space. (JP 3-14)
  space coordinating authority
  (DOD) The responsibility to plan, integrate, and coordinate space operations. Also called SCA. (JP 3-14)
  space domain
  (DOD) The area above the altitude where atmospheric effects on airborne objects become negligible.
  (JP 3-14)
  space environment
  (DOD) The environment corresponding to the space domain, where electromagnetic radiation, charged
  particles, and electric and magnetic fields are the dominant physical influences, and that encompasses
  the Earth’s ionosphere and magnetosphere, interplanetary space, and the solar atmosphere. (JP 3-59)
  space forces
  (DOD) The space and terrestrial systems, equipment, facilities, organizations, and personnel, or

  Strategic Command, in which space operations are conducted. Also called SJOA. (JP 3-14)
  Note. It is expected SJOA will eventually be modified to reference USSPACECOM.
  space situational awareness
  (DOD) The requisite foundational, current, and predictive knowledge and characterization of space
  objects and the operational environment upon which space operations depend. Also called SSA. (JP 3-
  14)
  space superiority
  (DOD) The degree of control in space of one force over any others that permits the conduct of its
