Military Space Program Of The United States
A military, also known collectively as armed forces, is a heavily armed, highly organized force primarily intended for warfare. It is typically authorized and maintained by a sovereign state, with its members identifiable by their distinct military uniform. It may consist of one or more military branches such as an army, navy, air force, space force, marines, or coast guard. The main task of the military is usually defined as defence of the state and its interests against external armed threats. In broad usage, the terms ''armed forces'' and ''military'' are often treated as synonymous, although in technical usage a distinction is sometimes made in which a country's armed forces may include both its military and other paramilitary forces. There are various forms of irregular military forces, not belonging to a recognized state; though they share many attributes with regular military forces, they are less often referred to as simply ''military''. A nation's military may f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
DARPA
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 Economist'' has called DARPA the agency "that shaped the modern world," and pointed out that " Moderna's COVID-19 vaccine sits alongside weather satellites, GPS, drones, stealth technology, voice interfaces, the personal comput ...

Spacecraft Launched In 2007
A spacecraft is a vehicle or machine designed to fly in outer space. A type of artificial satellite, spacecraft are used for a variety of purposes, including communications, Earth observation, meteorology, navigation, space colonization, planetary exploration, and transportation of humans and cargo. All spacecraft except single-stage-to-orbit vehicles cannot get into space on their own, and require a launch vehicle (carrier rocket). On a sub-orbital spaceflight, a space vehicle enters space and then returns to the surface without having gained sufficient energy or velocity to make a full Earth orbit. For orbital spaceflights, spacecraft enter closed orbits around the Earth or around other celestial bodies. Spacecraft used for human spaceflight carry people on board as crew or passengers from start or on orbit (space stations) only, whereas those used for robotic space missions operate either autonomously or telerobotically. Robotic spacecraft used to support scientific ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SPADEX
SPADEX or Space Docking Experiment is a twin spacecraft mission being developed by Indian Space Research Organisation to mature technologies related to orbital rendezvous, docking, formation flying, with scope of applications in human spaceflight, in-space satellite servicing and other proximity operations. SPADEX campaign would consist of two IMS class (200 kg) satellites, one would be Chaser and other being Target and both would be launched as co-passengers or auxiliary payloads. Both spacecraft would be injected into slightly different orbits. Space Docking Experiment is currently scheduled for launch from Satish Dhawan Space Centre aboard a Polar Satellite launch Vehicle.

ETS-VII
The ETS-VII, or Engineering Test Satellite No. 7, was a satellite developed and launched by the National Space Development Agency of Japan (NASDA). It is also known as KIKU-7. It was launched aboard an H-II rocket from Tanegashima Space Center, on 28 November 1997. The ETS-VII was equipped with a robotic arm, which was used to carry out several experiments related to rendezvous docking and space robotics. It was the world's first satellite to be equipped with a robotic arm, and also Japan's first uncrewed spacecraft to conduct autonomous rendezvous and docking operations successfully, decades after the docking of the Soviet Kosmos 186 and Kosmos 188 spacecraft in 1967. Although it was originally intended to be used for 1.5 years, the satellite was functional for a period of almost five years. ETS-VII eventually decayed from orbit on 13 November 2015. Features The ETS-VII consists of two main parts; the chaser satellite and the target satellite. The chaser satellite is the main ...

Kosmos 186 And Kosmos 188
Kosmos 186 (russian: Космос-186 meaning ''Cosmos 186'') and Kosmos 188 (russian: Космос-188 meaning ''Cosmos 188'') were two uncrewed Soviet Union spacecraft that incorporated a Soyuz programme descent module for landing scientific instruments and test objects. Mission Because of the lethal outcome of both the Soyuz 1 and the Apollo 1 missions earlier that year it was decided to proceed with unmanned flights first. But because the Soviet Union had no ground stations outside its own territory, this meant the docking had to be fully automated. After the first attempt failed (a fly by at a distance of ), the second attempt succeeded over the South Atlantic. However, this docking was not entirely successful either — the modules were mechanically docked, but not electrically. Also, the manoeuvre had cost more fuel than anticipated. On 27 October 1967 at 09:29:59 GMT, the Soyuz 11A511 s/n U15000-05 booster and Kosmos 186 were set up at Site 31/6 of Baikonur Cosmodro ...

Ground Segment
A ground segment consists of all the ground-based elements of a space system used by operators and support personnel, as opposed to the space segment and user segment. The ground segment enables management of a spacecraft, and distribution of payload data and telemetry among interested parties on the ground. The primary elements of a ground segment are: * Ground (or Earth) stations, which provide radio interfaces with spacecraft * Mission control (or operations) centers, from which spacecraft are managed * Remote terminals, used by support personnel * Spacecraft integration and test facilities * Launch facilities * Ground networks, which allow for communication between the other ground elements These elements are present in nearly all space missions, whether commercial, military, or scientific. They may be located together or separated geographically, and they may be operated by different parties. Some elements may support multiple spacecraft simultaneously. Elements Groun ...

Aviation Week
''Aviation Week & Space Technology'', often abbreviated ''Aviation Week'' or ''AW&ST'', is the flagship magazine of the Aviation Week Network. The weekly magazine is available in print and online, reporting on the aerospace, defense and aviation industries, with a core focus on aerospace technology. It has a reputation for its contacts inside the United States military and industry organizations. ''Aviation Week'' was a favorite conduit for defense-related companies and labs to leak information to the public as part of their policy by press release efforts. This led to it being informally referred to "Aviation Leak and Space Mythology". History The magazine was first published in August 1916. Early editors Ladislas d'Orsy and Donald W. McIlhiney (1921 to 25) were Quiet Birdmen. Publisher (1927 to 29) Earl D. Osborn was also a Quiet Birdman. With the coming of the Space Age, the current title was adopted in 1960. Other titles the magazine has held include ''Aviation & Aircraft ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hydrazine
Hydrazine is an inorganic compound with the chemical formula . It is a simple pnictogen hydride, and is a colourless flammable liquid with an ammonia-like odour. Hydrazine is highly toxic unless handled in solution as, for example, hydrazine hydrate (). Hydrazine is mainly used as a foaming agent in preparing polymer foams, but applications also include its uses as a precursor to polymerization catalysts, pharmaceuticals, and agrochemicals, as well as a long-term storable propellant for in-space spacecraft propulsion. Additionally, hydrazine is used in various rocket fuels and to prepare the gas precursors used in air bags. Hydrazine is used within both nuclear and conventional electrical power plant steam cycles as an oxygen scavenger to control concentrations of dissolved oxygen in an effort to reduce corrosion. the world hydrazine hydrate market amounted to $350 million. About two million tons of hydrazine hydrate were used in foam blowing agents in 2015. Hydra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
