AKA: Science and Technology Satellite. Status: Operational 2003. First Launch: 2003-09-27. Last Launch: 2013-11-21. Number: 5 . Gross mass: 100 kg (220 lb).

The objective of the Science and Technology Satellite project was development and in-orbit test of an indigenously-developed Korean 100-kg class small satellite bus and demonstration of high performance 3-axis attitude control capability.

The program began in October 1998. Important objectives were the development of advanced technology for future space missions, obtaining experience in high performance scientific payload design, research in space science, and conducting communications technology experiments and oceanography research using land and sea based mobile terminals. The first STSat was launched in September 2003 aboard a Russian booster, and the second was used an indigenous KSLV-1 launch vehicle.

Later in the series carried the MIRIS infrared astronomy experiment (an 8 cm telescope operating at 0.9-2 microns with a 4 degree field of view for spectroscopy of diffuse extended emission), as well as earth imaging and technology payloads.
