The US has successfully struck a disabled spy satellite with a missile fired from a warship in waters west of Hawaii, military officials say. So there is no danger to all of us (hydrazine exposure). As reported earlier the satellite, which no longer can be controlled, could contain hazardous materials, and it is unknown where on the planet it might come down. The Pentagon (the headquarters of the United States Department of Defense, located in Arlington, Virginia.) used a missile to shoot down the satellite:
Operatives had only a 10-second window to hit the satellite – USA 193 – which went out of control shortly after it was launched in December 2006. Officials were worried its hydrazine fuel could do harm, but it is not yet known if the fuel tank was destroyed. On Tuesday, a US State Department spokesman stressed that the action was meant to protect people from the hazardous fuel and was not a weapons test. The US government has also denied claims that the main aim of the operation was to destroy secret components on USA 193. Officials say classified parts would be burned up in the atmosphere and, in any case, that would not be a reason for shooting down the satellite.
=> US missile hits ‘toxic satellite’
A reconnaissance satellite aka spy satellite used for military or intelligence applications. One of such large U.S. spy satellite has lost power and could hit the Earth in late February or March. The worst part is US government not sure where it will hit on earth. From the yahoo news source:
The satellite, which no longer can be controlled, could contain hazardous materials, and it is unknown where on the planet it might come down, hey said. The officials spoke on condition of anonymity because the information is classified as secret. Appropriate government agencies are monitoring the situation,” said Gordon Johndroe, a spokesman for the National Security Council. “Numerous satellites over the years have come out of orbit and fallen harmlessly. We are looking at potential options to mitigate any possible damage this satellite may cause
According to wikipedia:
The KH-11, also referenced by the codenames 1010, Crystal and Kennan, also commonly known as “Key Hole”, was a type of reconnaissance satellite launched by the American National Reconnaissance Office between December 1976 and 1990 and used until present. It is believed to resemble the Hubble Space Telescope in size and shape, as the satellites were shipped in similar containers. Using a powerful 2.3-meter mirror, the theoretical ground resolution with no atmospheric degradation and 50% MTF would be roughly 0.15 meter (6 inches). Operational resolution would be worse due to effects of the atmosphere. Different versions of the KH-11 vary in mass from 13,000 to 13,500 kilograms. Its length is believed to be 19.5 meters, and diameter is 3 meters or less.
=> Disabled spy satellite threatens Earth
India successfully launches an Israeli spy satellite, from Sriharikota (island off the coast of Andhra Pradesh in India) space station, AP. Sriharikota is used by the Indian Space Research Organisation to launch satellites using multi-stage rockets such as the Polar Satellite Launch Vehicle or the Geosynchronous Satellite Launch Vehicle. This clear shows that India is eager to compete in the world space technology market which is worth multi-billion-dollar industry.
The launch of the Tecsar satellite by an Indian-made rocket was carried out in clear weather at 9:15 am local time from the Sriharikota space station in southern India, the Indian Space Research Organisation said.
The 300-kilogramsatellite, sometimes referred to as the Polaris, was steered into orbit about 20 minutes later, said Antrix Corporation, the marketing arm of the Bangalore-based space agency. It is the second commercial launch of a foreign satellite by India, which sent into space an Italian satellite in April last year.
India wants to join and compete with the United States, Russia, China, the Ukraine and the European Space Agency in offering commercial satellite launch services, a market worth up to 2.5 billion dollars a year.
