Spy Satellite's biggest Horizon

The use of satellites for intelligence purposes, which began in the Cold War, are still ongoing. SUNDAY nights ago, 21 November, America launched a spy satellite at Cape Canaveral Air Force Base, Florida. He is the second satellite in the last three months, launched the National Reconnaissance Office (NRO), an American intelligence agency in charge of designing, creating, and build a spy satellite for the U.S. government.
NRO keep detailed specifications, but as reported by CNN, the NRO director Bruce Carlson announced last September that the agency where she worked would 'put the world's largest satellite' above the Delta rocket and launch it this fall. He also added that the NRO satellite mission 'is the most aggressive launch ever undertaken by the NRO in the last 20 years. "
American spy satellites NROL-32Pejabat largest U.S. government refused to confirm the purpose of launching satellites. But with such a large antenna size, satellite NROL-32 that have the ability to capture the communication opponent.
As reported by the BBC, satellite estimated NROL-32 aircraft equipped with highly sensitive radio and an antenna 328 feet long, nearly five times larger than any commercial antenna ever launched. The use of satellites for intelligence purposes has started America since the Cold War.
On March 16, 1955 U.S. Air Force officially ordered the making of a spy satellite to monitor the ability of American military opponents. President Dwight D. Eisenhower approved a program to replace the planes U-2 which has been used to take a photograph Soviet territory from the air. CIA and the U.S. Air Force and then work together to make a first-generation space program that worked very quickly and full confidentiality.
Corona, American spy satellites first 1960Pada August 1960, after twelve attempts that failed, American spy satellites first, Corona, orbits. The spacecraft is in operation until May 1972. Corona main task is to take pictures of secret locations strategically Soviet military. Soviets did not want to lose, Zenit launch, a rival spy satellite, in 1961.
In Spies in the Sky: Surveillance satellites in War and Peace, Pat Norris wrote that Corona has tiny cameras that show the horizon and star clusters, which enables the analysts determine the direction of the satellite, and to precisely determine the location of the object of the photos taken.
During orbit, improved technical capabilities Corona. In 1960 Corona was able to be directed to photograph specific objects. Until the end of the operation, Corona managed to record about 800,000 images, record arms deal between the Soviet and dipasoknya countries, also provide accurate data about the Soviet military strategic capability.
American leaders rely on the data collected Corona before signing the agreement with the Soviet Union. Corona secret status, and several other reconnaissance satellites, Argon and Lanyard, revealed over the executive order of President Bill Clinton on February 24, 1995. The pictures are successfully recorded for later use by American scientists to map the environmental changes that have occurred since the 1960s.
United Lauch Alliance, formed joint ventures Boeing and Lockheed Martin, NROL-32 satellite launched on a Delta IV Heavy rocket. This is the launch of the fourth using the same rocket. The launch was used three kinds of drivers that can generate power and push objects weighing 13 tons to the space station orbit (geostationary). Two other satellites ever launched using a Delta IV Heavy quoted by Popular Science as a spy satellite.
In the second week of November 2010, Boeing announced the successful launch of SkyTerra 1, a reflector antenna over 72 feet, the largest commercial satellite antenna. Previous record for the largest antenna in the satellite TerraStar-1 as long as 60 feet.
Satellite Observers told SpaceFlightNow that they believe the charge is a rocket with electronic signals intelligence satellites; to the present four similar satellites already orbiting. Similar satellites known as Mentor or Advanced Orion has been used since 1995. [VIFI / Popular Science / CNN]
