Near Field Infrared Experiment
The Near Field Infrared Experiment (NFIRE) was a satellite that was proposed and developed by the Missile Defense Agency, a division of the United States Department of Defense. It was launched atop a Minotaur rocket, from Wallops Island, at 06:48 GMT on 24 April 2007. Though primarily designed to gather data on exhaust plumes from rockets, the satellite was also intended to contain a kill vehicle similar to kinds intended for the Strategic Defense Initiative. A missile was then to be fired at and nearly miss the instrumented kill vehicle. This feature was later removed. NFIRE was funded by $44 million in FY2004. In 2004, the United States House of Representatives instructed the Missile Defense Agency, MDA, to remove the kill vehicle from the planned 2006 NFIRE launch, approving $68 million in FY2005 subject to that condition. The Senate Appropriations Committee reviewing the NFIRE program, however, urged the MDA to return the missile defense interceptor ( kill vehicle) to the o ...

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 place" as "spac ...

Satellites Of The United States
A satellite or artificial satellite is an object intentionally placed into orbit in outer space. Except for passive satellites, most satellites have an electricity generation system for equipment on board, such as solar panels or radioisotope thermoelectric generators (RTGs). Most satellites also have a method of communication to ground stations, called transponders. Many satellites use a standardized bus to save cost and work, the most popular of which is small CubeSats. Similar satellites can work together as a group, forming constellations. Because of the high launch cost to space, satellites are designed to be as lightweight and robust as possible. Most communication satellites are radio relay stations in orbit and carry dozens of transponders, each with a bandwidth of tens of megahertz. Satellites are placed from the surface to orbit by launch vehicles, high enough to avoid orbital decay by the atmosphere. Satellites can then change or maintain the orbit by propulsion, ...

Missile Defense
Missile defense is a system, weapon, or technology involved in the detection, tracking, interception, and also the destruction of attacking missiles. Conceived as a defense against nuclear-armed intercontinental ballistic missiles (ICBMs), its application has broadened to include shorter-ranged non-nuclear tactical and theater missiles. China, France, India, Iran, Israel, Italy, Russia, Taiwan, the United Kingdom and the United States have all developed such air defense systems. Missile defense categories Missile defense can be divided into categories based on various characteristics: type/range of missile intercepted, the trajectory phase where the intercept occurs, and whether intercepted inside or outside the Earth's atmosphere: Type/range of missile intercepted These types/ranges include strategic, theater and tactical. Each entails unique requirements for intercept, and a defensive system capable of intercepting one missile type frequently cannot intercept others. H ...

Spacecraft Which Reentered In 2015
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] |

The Tesat-Spacecom GmbH & Co. KG (TESAT) from Backnang, Germany is an independently operating subsidiary of Airbus Defence and Space which develops, produces and tests communication payloads for international satellite manufacturers. Company History In 1949, the AEG (Allgemeine Elektricitäts Gesellschaft AG) business area telecommunications technology was relocated from Berlin to Backnang.

Senate Appropriations Committee
The United States Senate Committee on Appropriations is a standing committee of the United States Senate. It has jurisdiction over all discretionary spending legislation in the Senate. The Senate Appropriations Committee is the largest committee in the U.S. Senate, with 30 members in the 117th Congress. Its role is defined by the U.S. Constitution, which requires "appropriations made by law" prior to the expenditure of any money from the Treasury, and the committee is therefore one of the most powerful committees in the Senate. The committee was first organized on March 6, 1867, when power over appropriations was taken out of the hands of the Finance Committee. The chairman of the Appropriations Committee has enormous power to bring home special projects (sometimes referred to as "pork barrel spending") for their state as well as having the final say on other senators' appropriation requests. For example, in fiscal year 2005 per capita federal spending in Alaska, the home state ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Strategic Defense Initiative
The Strategic Defense Initiative (SDI), derisively nicknamed the "''Star Wars'' program", was a proposed missile defense system intended to protect the United States from attack by ballistic strategic nuclear weapons (intercontinental ballistic missiles and submarine-launched ballistic missiles). The concept was announced on March 23, 1983, by President Ronald Reagan,Federation of American ScientistsMissile Defense Milestones Accessed March 10, 2007. a vocal critic of the doctrine of mutually assured destruction (MAD), which he described as a " suicide pact". Reagan called upon American scientists and engineers to develop a system that would render nuclear weapons obsolete. The Strategic Defense Initiative Organization (SDIO) was set up in 1984 within the US Department of Defense to oversee development. A wide array of advanced weapon concepts, including lasers, Duarte, F. J. (Ed.), ''Proceedings of the International Conference on Lasers '87'' (STS, McLean, Va, 1988). particle be ...

Minotaur Rocket
The Minotaur is a family of United States solid fuel launch vehicles derived from converted Minuteman and Peacekeeper intercontinental ballistic missiles (ICBM). They are built by Northrop Grumman via contract with the Air Force Space and Missile Systems Center's Space Development and Test Directorate (SMC/SD) as part of the Air Force's Rocket Systems Launch Program which converts retired Intercontinental Ballistic Missiles into space and test launch systems for U.S. government agencies. Three variants of the Minotaur are currently in service. The Minotaur I is an orbital launch system used to launch small satellites into low Earth orbit (LEO). The Minotaur II is a target launch vehicle (TLV), also known as Chimera, used for suborbital flights, often as a target for tracking and anti-ballistic missile tests. The Minotaur IV is a more capable LEO launch system. The Minotaur V is designed to reach higher orbits, including geostationary transfer orbit (GTO) and trans-lunar tra ...
