STSat-2A
STSat-2A (Science and Technology Satellite-2A) [1] was 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) launch vehicle.It was expected to be operational for about two years, and was scheduled to be launched between 2005 and 2007.Originally a Dual-channel Radiometers for Earth and Atmosphere Monitoring (DREAM) microwave radiometer was intended as the principal payload of STSat-2A for an expected launch in 2007.[5] STSat-2A was launched on the maiden flight of the Naro-1 launch vehicle, which lifted off the Naro Space Center, on the southern coast of South Korea at 08:00:33 UTC on 25 August 2009.[7] This resulted in the second stage being too heavy to reach orbit, and it fell back to Earth along with the satellite.
