STSAT-2 (Science and Technology Satellite-2) is a satellite launched by the Korea Aerospace Research Institute (KARI), the national space agency of South Korea, from the Naro Space Center in Goheung County, South Jeolla using the Naro-1 (KSLV-1) rocket.[1][2]
The 100-kilogram (220 lb) satellite carries a Lyman- alpha Imaging Solar Telescope (LIST) as well as Satellite laser ranging (SLR) payload.[3]
The Satellite Technology Research Center (SaTReC) developed the STSAT-2 as a sun observation, satellite laser ranging and engineering and technology demonstration sponsored by the Ministry of Science and Technology. It is expected to have a space life of about two years, and was expected to be launched between 2005 and 2007.[4]
The Satellite Laser Ranging (SLR) mission will measure the orbit of STSAT-2, to investigate variations in orbit.[5]
Satellite STSAT-1 was launched by Cosmos 3M on Sept. 27, 2003. Originally a Dual-channel Radiometers for Earth and Atmosphere Monitoring (DREAM) Microwave radiometer was intended as the principle payload of STSAT-2 for an expected launch in 2007.[6] The Laser Retro-reflector Array (LRA) is described as an early expected payload for STSAT-2 which would consist of nine retro-reflectors in a mechanical casing.[4]
The follow up program is STSAT-2 which has three missions, the indigenous research and development to place a satellite into low orbit, development of indigneous spacecraft, and the ability to develop scientific payloads.[5]
South Korea's first space rocket successfully lifted off from the country's launch pad on the southern coast on 25 August 2009 but failed to put the STSAT-2 satellite into the target orbit. The rocket had to separate from the scientific satellite at an altitude of 306 km but instead, the rocket separated at an altitude of 340 km.[7] Currently, it is presumed that the satellite has reentered the atmosphere and disintegrated. Further investigation is going on.
