Space Systems Command
Space Systems Command (SSC) is the United States Space Force's research and development, space development, Military acquisition, acquisition, space launch, launch, and Military logistics, logistics field command. It is headquartered at Los Angeles Air Force Base, California, and manages the United States' space launch ranges. Air Research and Development Command was redesignated as Air Force Systems Command in 1961. As part of that reorganization, the Space Systems Division (SSD) was established on 20 Mar 1961 and organized (activated) on 1 Apr 1961. In 1967, the Space Systems Division was reorganized as the Space and Missile Systems Organization (SAMSO), absorbing the Ballistic Systems Division's mission. In 1979, the Space and Missile Systems Organization was renamed the Space Division and divested itself of ballistic missile development. In 1989, the Space Division returned to its historic name of the Space Systems Division and regained its ballistic missile development ro ...

Flag Of The Space Systems Command
A flag is a piece of fabric (most often rectangular) with distinctive colours and design. It is used as a symbol, a signalling device, or for decoration. The term ''flag'' is also used to refer to the graphic design employed, and flags have evolved into a general tool for rudimentary signalling and identification, especially in environments where communication is challenging (such as the maritime environment, where semaphore is used). Many flags fall into groups of similar designs called flag families. The study of flags is known as "vexillology" from the Latin , meaning "flag" or "banner". National flags are patriotic symbols with widely varied interpretations that often include strong military associations because of their original and ongoing use for that purpose. Flags are also used in messaging, advertising, or for decorative purposes. Some military units are called "flags" after their use of flags. A ''flag'' (Arabic: ) is equivalent to a brigade in Arab countries. In ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Communication Satellite
A communications satellite is an artificial satellite that relays and amplifies radio telecommunication signals via a transponder; it creates a communication channel between a source transmitter and a receiver at different locations on Earth. Communications satellites are used for television, telephone, radio, internet, and military applications. Many communications satellites are in geostationary orbit above the equator, so that the satellite appears stationary at the same point in the sky; therefore the satellite dish antennas of ground stations can be aimed permanently at that spot and do not have to move to track the satellite. Others form satellite constellations in low Earth orbit, where antennas on the ground have to follow the position of the satellites and switch between satellites frequently. The radio waves used for telecommunications links travel by line of sight and so are obstructed by the curve of the Earth. The purpose of communications satellites is to re ...

Advanced Research Projects Agency
The Defense Advanced Research Projects Agency (DARPA) is a research and development agency of the United States Department of Defense responsible for the development of emerging technologies for use by the military. Originally known as the Advanced Research Projects Agency (ARPA), the agency was created on February 7, 1958, by President Dwight D. Eisenhower in response to the Soviet launching of Sputnik 1 in 1957. By collaborating with academia, industry, and government partners, DARPA formulates and executes research and development projects to expand the frontiers of technology and science, often beyond immediate U.S. military requirements.Dwight D. Eisenhower and Science & Technology, (2008). Dwight D. Eisenhower Memorial CommissionSource The name of the organization first changed from its founding name, ARPA, to DARPA, in March 1972, changing back to ARPA in February 1993, then reverted to DARPA in March 1996.

Eisenhower Administration
Dwight D. Eisenhower's tenure as the 34th president of the United States began with his first inauguration on January 20, 1953, and ended on January 20, 1961. Eisenhower, a Republican from Kansas, took office following his landslide victory over Democratic nominee Adlai Stevenson in the 1952 presidential election. Four years later, in the 1956 presidential election, he defeated Stevenson again, to win re-election in a larger landslide. Eisenhower was limited to two terms and was succeeded by Democrat John F. Kennedy, who won the 1960 presidential election. Eisenhower held office during the Cold War, a period of geopolitical tension between the United States and the Soviet Union. Eisenhower's New Look policy stressed the importance of nuclear weapons as a deterrent to military threats, and the United States built up a stockpile of nuclear weapons and nuclear weapons delivery systems during Eisenhower's presidency. Soon after taking office, Eisenhower negotiated an en ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sputnik 1
Sputnik 1 (, , ''Satellite 1''), sometimes referred to as simply Sputnik, was the first artificial Earth satellite. It was launched into an elliptical low Earth orbit by the Soviet Union on 4 October 1957 as part of the Soviet space program. It sent a radio signal back to Earth for three weeks before its three silver-zinc batteries became depleted. Aerodynamic drag caused it to fall back into the atmosphere on 4 January 1958. It was a polished metal sphere in diameter with four external radio antennas to broadcast radio pulses. Its radio signal was easily detectable by amateur radio operators, and the 65° orbital inclination made its flight path cover virtually the entire inhabited Earth. The satellite's success was unanticipated by the United States. This precipitated the American Sputnik crisis and triggered the Space Race. The launch was the beginning of a new era of political, military, technological, and scientific developments. The word ''sputnik'' is Russian for ...

Air Force Space Command
An atmosphere () is a layer of gases that envelop an astronomical object, held in place by the gravity of the object. A planet retains an atmosphere when the gravity is great and the temperature of the atmosphere is low. A stellar atmosphere is the outer region of a star, which includes the layers above the opacity (optics), opaque photosphere; stars of low temperature might have outer atmospheres containing compound molecules. The atmosphere of Earth is composed of nitrogen (78%), oxygen (21%), argon (0.9%), Carbon dioxide in Earth's atmosphere, carbon dioxide (0.04%) and trace gases. Most organisms use oxygen for respiration (physiology), respiration; lightning and bacteria perform nitrogen fixation which produces ammonia that is used to make nucleotides and amino acids; plants, algae, and cyanobacteria use carbon dioxide for photosynthesis. The layered composition of the atmosphere minimises the harmful effects of sunlight, ultraviolet radiation, solar wind, and cosmic rays ...

Air Research And Development Command
The Air Force Systems Command (AFSC) is an inactive United States Air Force Major Command. It was established in April 1951, being split off from Air Materiel Command. The mission of AFSC was Research and Development for new weapons systems. AFSC took on engineering functions which formerly resided in the Air Materiel Command (AMC), the Army Air Forces Technical Service Command, and the Air Technical Service Command (ATSC) as a separate research and development command in 1950. It incorporated Air Proving Ground Command in 1957. On 1 July 1992, AFSC and Air Force Logistics Command were merged to form the Air Force Materiel Command, located at Wright-Patterson Air Force Base, Ohio. In the reorganization of 1961, Air Force Systems Command acquired the materiel procurement function from Air Force Logistics Command. It was re-integrated with Air Force Logistics Command in 1992.

Space Launch Range
A spaceport or cosmodrome is a site for launching or receiving spacecraft, by analogy to a seaport for ships or an airport for aircraft. The word ''spaceport''—and even more so ''cosmodrome''—has traditionally referred to sites capable of launching spacecraft into Earth orbit or on interplanetary trajectories. However, rocket launch sites for sub-orbital spaceflights are also sometimes called spaceports, especially as new and proposed facilities for suborbital commercial spaceflight are often branded as "spaceports." Space stations and proposed future lunar bases are also sometimes referred to as spaceports, particularly when envisioned as nodes for further interplanetary travel. Spaceports are evolving beyond traditional government-run complexes into multi-functional aerospace hubs, increasingly driven by private companies such as SpaceX, Blue Origin, and Virgin Galactic. A prominent example is Starbase, a private spaceport operated by SpaceX in Boca Chica, Texas. Starb ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
