Güney Kore Gözlem Uydusu Fırlattı

Güney Kore bugün TSİ 1005'de KOMPSAT-2 (Arirang-2) adlı gözlem uydusunu fırlattı. Coğrafi ve ekolojik araştırmaların yanısıra Kuzey Kore füze çalışmalarının da takip edilmesinde kullanılacak uydunun çözünürlüğü siyah beyaz görüntüler için 1.0-2.0m, renkli görüntüler için ise 4.0m. Uydu Rusya'daki Plesetsk uzay üssünden SL-19 (Rokot) roketi vasıtası ile yörüngeye yerleştirildi.





Arirang-2 Satellite Set For Launch

Korea's multi-purpose satellite Arirang-2 is scheduled to lift off today aboard a rocket -- converted from an intercontinental ballistic missile -- shortly after 4 p.m. (Korean Time) from a Russian spaceport. The launch comes a day after a miniature satellite made by a Korean college blew up when its transportation rocket exploded.

The 900-kilogram-heavy satellite, designed by the Korea Aerospace Research Institute, is expected to provide a substantially improved reconnaissance capacity to the country thanks to its multi-spectral camera (MSC).

"Loaded with Arirang-2, the Rockot rocket of Russia is to take off from a launch pad in the Plesetsk Cosmodrome, approximately 800 kilometers northeast of Moscow," said Choi Hae-jin, director at the state-backed institute.

"The MSC on Arirang-2, which will be placed at an altitude of 685 kilometers, has multiple functions including airborne surveillance," he added.

Originally, Arirang-2 was designed as a remote-sensing device for geographical surveys, natural resource searches and environmental observation. However, the high-definition MSC will be able to give real-time visual data on North Korea's missile launch preparations or military activities, which would be otherwise unavailable.

The camera can identify an object one meter in diameter. Only a handful of countries have satellite-based cameras as powerful.

Meanwhile, the miniature satellite made by researchers at Hankuk Aviation University, named Hausat-1, yesterday morning failed to achieve orbit when its booster rocket failed.

The Dnepr rocket -- also a converted missile -- carried 18 satellites including Hausat-1 but crashed shortly after takeoff from Kazakhstan.

Hausat-1 was a small box-sized satellite built on a minimal budget to help students understand the process of manufacturing satellites.


ROK launches multipurpose satellite successfully

SEOUL, July 28 (Xinhua) -- South Korea announced Friday that a South Korean multipurpose satellite was launched successfully in Russia in the afternoon.

The satellite, which was dubbed Arirang 2, was lifted off from the Plesetsk Cosmodrome, about 800 km northeast of Moscow, by a Russian rocket and has successfully sent signals to the Kenya satellite telemetry station from its orbit, said the South Korean Science Ministry and the Korea Aerospace Research Institute (KARI).

The Arirang 2 is expected to send a picture to South Korea's Daejeon ground control station around midnight from its orbit 685 km above the Earth, the ministry said.

The Arirang 2 satellite, which is designed for geographical updates, natural resource searches and environmental observation, will operate in a low orbit of 685 km from the earth and send high-resolution pictures of the earth's surface to South Korea.

According to local reports, local companies and Israel's Electro Optical Industries Ltd. jointly developed the high-resolution, multispectral camera equipped on the satellite, which has a resolution of 1 square meter that can distinguish individual cars on the ground.

The KARI said the satellite will travel 6.8 km a second and circle the globe more than 14 times a day.

South Korea launched the Arirang 1 satellite, which has a camera resolution that can distinguish buildings, in 1999.

Arirang 2 is the 9th South Korean satellites currently operating in space.

Following the Arirang 2, the KARI said South Korea will move forward with its space program that envisions sending 13 satellites into space by 2010.

Under the program, South Korea is expected to complete the construction of a rocket center in Goheung on the country's south coast next year and use a locally-built rocket to send a 100-kg mini satellite into orbit.

South Korea plans to launch the Arirang 3, which is likely to be equipped with a camera with a resolution of about 70 cm, next year and the Arirang 5, which will be equipped with a radar imaging device that can detect developments on the Earth's surfaceat night and in bad weather, in 2008.
