SLC-4E
Space Launch Complex 4 (SLC-4) is a launch and landing site at Vandenberg Space Force Base, California, U.S. It has two pads, both of which are used by SpaceX for Falcon 9, one for launch operations, and other as Landing Zone 4 (LZ-4) for SpaceX landings. The complex was previously used by Atlas (rocket), Atlas and Titan (rocket), Titan rockets between 1963 and 2005. It consisted of two launch pads, SLC-4W and SLC-4E, which were formerly designated PALC-2-3 and PALC-2-4 respectively.

Byeman Control System
The BYEMAN Control System, or simply BYEMAN (designated BYE, or B), was a security control system put in place to protect information about the National Reconnaissance Office and its operations. History The BYEMAN Control System was put in place in 1961 by the Central Intelligence Agency. Discussions regarding BCS retirement were held as early as 2003. NRO Director Peter B. Teets spoke at a 2003 NRO Town Hall meeting, mentioning that retiring the BCS would remove barriers that prevented the NRO and U.S. Intelligence Community from working together as a team. The use of BCS was so prevalent throughout the U.S. Intelligence Community, that a handful of websites were set up to direct users through the retirement process.

Anti-Ballistic Missile Treaty
The Anti-Ballistic Missile Treaty (ABM Treaty or ABMT) (1972–2002) was an arms control treaty between the United States and the Soviet Union on the limitation of the anti-ballistic missile (ABM) systems used in defending areas against ballistic missile-delivered nuclear weapons. It was intended to reduce pressures to build more nuclear weapons to maintain deterrence. Under the terms of the treaty, each party was limited to two ABM complexes, each of which was to be limited to 100 anti-ballistic missiles. Signed in 1972, it was in force for the next 30 years. In 1997, five years after the dissolution of the Soviet Union, four former Soviet republics agreed with the United States to succeed the USSR's role in the treaty. In June 2002 the United States withdrew from the treaty, leading to its termination, citing risks of nuclear blackmail. Background Throughout the late 1950s and into the 1960s, the United States and the Soviet Union had been developing missile systems wit ...

Space
Space is the boundless three-dimensional extent in which objects and events have relative position and direction. In classical physics, physical space is often conceived in three linear dimensions, although modern physicists usually consider it, with time, to be part of a boundless four-dimensional continuum known as spacetime. The concept of space is considered to be of fundamental importance to an understanding of the physical universe. However, disagreement continues between philosophers over whether it is itself an entity, a relationship between entities, or part of a conceptual framework. Debates concerning the nature, essence and the mode of existence of space date back to antiquity; namely, to treatises like the ''Timaeus'' of Plato, or Socrates in his reflections on what the Greeks called '' khôra'' (i.e. "space"), or in the '' Physics'' of Aristotle (Book IV, Delta) in the definition of ''topos'' (i.e. place), or in the later "geometrical conception of pl ...
