Quick Summary

The STSAT-2A was a South Korean satellite intended to be the first launched into orbit by the country. It had a mass of approximately 100 kg (220 pounds) and carried two scientific experiments: a radiometer for studying atmospheric water vapor and a laser ranging apparatus. The satellite was launched on August 25, 2009, using the Korea Space Launch Vehicle-1. However, a payload fairing failed to separate, preventing the satellite from reaching orbit. It burned up in Earth's atmosphere over the Pacific Ocean. STSAT-2B, an identical satellite, was launched on June 10, 2010, but the rocket exploded. STSAT-2C was successfully launched on January 30, 2013.12
