Six government-funded research institutes are working together to develop Lunar Infrared Spectrometer(LIRS), Gamma-ray Spectrometer(GRS), Neutron Spectrometer(NS) for future Korean lunar exploration since July of 2015. As a part of the space-core technology project, the goal is to develop the engineering models of them. Currently mechanical and electronic parts of LIRS are ready to assemble, and proto-models for GRS and NS are developed. Main sensors, such as IR sensor and HPGe sensor are delivered and tested. In addition, three instruments are successfully designed to satisfy the required mass, and power budget for spacecraft. In this paper, we will briefly present the current status in development of the instruments and the plan for the next  year.
