Spaceflight
Spaceflight (or space flight) is an application of astronautics to fly objects, usually spacecraft, into or through outer space, either with or without humans on board. Most spaceflight is uncrewed and conducted mainly with spacecraft such as satellites in orbit around Earth, but also includes space probes for flights beyond Earth orbit. Such spaceflights operate either by telerobotic or autonomous control. The first spaceflights began in the 1950s with the launches of the Soviet Sputnik satellites and American Explorer and Vanguard missions. Human spaceflight programs include the Soyuz, Shenzhou, the past Apollo Moon landing and the Space Shuttle programs. Other current spaceflight are conducted to the International Space Station and to China's Tiangong Space Station. Spaceflights include the launches of Earth observation and telecommunications satellites, interplanetary missions, the rendezvouses and dockings with space stations, and crewed spaceflights on sci ...

Mayak Launch Complex
The Mayak Production Association (, , from 'lighthouse') is one of the largest nuclear facilities in the Russian Federation, housing production reactors (''non'' electricity) and a reprocessing plant. The closest settlements are Ozyorsk to the northwest and Novogornyi to the south. Lavrentiy Beria led the Soviet atomic bomb project. He directed the construction of the Mayak plutonium plant in the Southern Urals between 1945 and 1948, in a great hurry and secrecy as part of the Soviet Union's atomic bomb project. The plant had a similar purpose to the Hanford Site of the Manhattan Project. Over 40,000 gulag prisoners and POWs built the factory and the closed nuclear city of Ozyorsk, called at the time by its classified postal code "Chelyabinsk-40". The first reactor, A-1, operated from 1948 and fuelled the first nuclear test RDS-1 in 1949. During the Cold War, 10 nuclear reactors were constructed, with a combined power of 7,333 MWth. Of these, four were used for plutonium pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kosmos-1
The Kosmos-1 (GRAU Index: 65S3, also known as Cosmos-1) was a Soviet carrier rocket (Kosmos (rocket family)), derived from the R-14 missile, which orbited satellites in 1964 and 1965. It served as an interim, and was quickly replaced by the Kosmos-3. Eight were flown, all launched from Site 41/15 at the Baikonur Cosmodrome. Initial development was authorised in October 1961, leading to a maiden flight on 18 August 1964, carrying three Strela satellites. Strela-1 satellites were flown on seven flights, three on each of the first four and five on the next three. The eighth and final flight carried one. All flights were successful except the second. Launch history See also *Kosmos-2I *Kosmos-3M The Kosmos-3M ( meaning "''Cosmos''", GRAU index 11K65M) was a Russian space launch vehicle, member of the Kosmos (rocket family), Kosmos rocket family.

Discoverer 33
Discoverer 33, also known as Corona 9026, was an American optical reconnaissance satellite which was lost in a launch failure in 1961. It was the eighth of ten Corona KH-2 satellites, based on the Agena-B. The launch of Discoverer 33 occurred at 19:23 UTC on 23 October 1961. A Thor DM-21 Agena-B rocket was used, flying from Launch Complex 75-3-5 at the Vandenberg Air Force Base. The launch was nominal through the Thor burn. Agena hydraulic system performance was erratic and resulted in numerous unplanned pitch and yaw maneuvers which drove the stage into an excessively lofted trajectory. At T+312 seconds hydraulic pressure was lost and the Agena began tumbling. The propulsion system shut down at T+322 seconds and the Agena fell into the Pacific. Following three occurrences of this failure mode in seven months, an extensive effort was made to redesign the Agena hydraulic system, improve weak points, and ensure that all systems were free of contamination. Discoverer 33 was inte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lincoln Laboratory
The MIT Lincoln Laboratory, located in Lexington, Massachusetts, is a United States Department of Defense federally funded research and development center chartered to apply advanced technology to problems of national security. Research and development activities focus on long-term technology development as well as rapid system prototyping and demonstration. Its core competencies are in sensors, integrated sensing, signal processing for information extraction, decision-making support, and communications. These efforts are aligned within ten mission areas. The laboratory also maintains several field sites around the world. The laboratory transfers much of its advanced technology to government agencies, industry, and academia, and has launched more than 100 start-ups.

Project West Ford
Project West Ford (also known as Westford Needles and Project Needles) was a test carried out by Massachusetts Institute of Technology's Lincoln Laboratory on behalf of the United States military in 1961 and 1963 to create an artificial ionosphere above the Earth. This was done to solve a major weakness that had been identified in military communications. History At the height of the Cold War, all international communications were either sent through submarine communications cables or bounced off the natural ionosphere. The United States military was concerned that the Soviets might cut those cables, forcing the unpredictable ionosphere to be the only means of communication with overseas forces. To mitigate the potential threat, Walter E. Morrow started Project Needles at the MIT Lincoln Laboratory in 1958. The goal of the project was to place a ring of 480,000,000 (Abstract) copper dipole antennas in orbit to facilitate global radio communication. The dipoles collectively prov ...

Dipole
In physics, a dipole () is an electromagnetic phenomenon which occurs in two ways: * An electric dipole moment, electric dipole deals with the separation of the positive and negative electric charges found in any electromagnetic system. A simple example of this system is a pair of charges of equal magnitude but opposite sign separated by some typically small distance. (A permanent electric dipole is called an electret.) * A magnetic dipole is the closed circulation of an electric current system. A simple example is a single loop of wire with constant current through it. A bar magnet is an example of a magnet with a permanent magnetic dipole moment. Dipoles, whether electric or magnetic, can be characterized by their dipole moment, a vector quantity. For the simple electric dipole, the electric dipole moment points from the negative charge towards the positive charge, and has a magnitude equal to the strength of each charge times the separation between the charges.
