S. Korea to extend operational life of multipurpose satellite
제목 없음
South Korea will extend the operational life of its multipurpose satellite by
two years following the evaluation of its mechanical, communications and power
systems, a state-run research institute said Wednesday.
The Korea Aerospace Research Institute (KARI) said the Arirang 2 satellite is working normally although it surpassed its initial life span of three years in 2009.
With an extended operational life span, the Arirang 2 can continue its mission of providing detailed images of the Earth's surface that can be used for various purposes up until July 2013, the institute said.
The satellite is equipped with a high-resolution, multi-spectral camera that has a resolution of 1 square meter, close enough to distinguish individual cars on the ground.
"All command and control systems, data collection, sending capability and energy reserves have been checked to be in operational order," KARI, located in Daejeon, 160 kilometers south of Seoul, said.
The 800 kilogram satellite, launched in late July 2006 from Russia's Plesetsk Cosmodrome, has already circled the globe more than 26,000 times and sent more than 2 million pictures so far. KARI said that since 2007, it has sold 15,000 pictures that the satellite took.
South Korea said it took seven years and 263 billion won (US$250 million) to build the multipurpose satellite.
