STSat-2B, or Science and Technology Satellite-2B, was a South Korean satellite which was lost in the failure of the second flight of the Naro-1 launch vehicle. It was to have been operated by the Korea Aerospace Research Institute (KARI), and was intended to demonstrate technology for future spacecraft. The satellite had a mass of 100 kg (220 lb),^[2] and was expected to operate for at least two years.^[1]

STSat-2B was originally intended to operate alongside a second spacecraft, STSat-2A; however STSat-2A was lost in 2009 after the payload fairing of its carrier rocket failed to separate, leaving the rocket unable to achieve orbit.^[4]
