South Korea is ending the mission of its first multipurpose satellite, launched in 1999, after losing contact with it at the end of December, its space agency said on Friday. The Arirang satellite had an original mission of three years, mapping the Earth's surface. It continued in operation for several more years after that, the Korea Aerospace Research Institute said. The satellite is programmed to use emergency power if it loses contact with controllers. That power source is expected to be depleted at the end of this month, it said.
South Korea's state-run aerospace research institute said Friday that it has lost communication with the country's first multipurpose satellite. The Korea Aerospace Research Institute (KARI) said its surface uplink with the Arirang 1 satellite was lost on Dec. 30. KARI said experts have been tasked to find the cause of the problem and restore communications, but they have been unable to make contact with the orbiting satellite.
South Koreas first multipurpose satellite Arirang 1 has fallen silent according to the Korea Aerospace Research Institute (KARI). KARI lost communication with the Arirang 1 satellite on Dec. 30. Initial reviews indicate a mechanical malfunction or a solar panel misalignment that may have affected the power supply.
Arirang 1 was launched on Dec. 21, 1999, from the Vandenberg Air Force Base in California, US, and orbits the earth every 98 minutes at an altitude of 680 - 671 km from the earths surface. So far, it has orbited the globe 42,985 times and taken 440,000 high-resolution photos.
The satellite will be formally declared within a week, if experts cannot restore communications with the orbiting satellite or find the cause of the problem. The satellite is expected to orbit the earth for some years before atmosphere drag causes it to burn up in the earths atmosphere and be destroyed.
