MIRIS(Multi-purpose Infrared Imaging System) is the first astronomical infrared space telescope in Korea developed by KASI in collaboration with SaTReC, KARI and ISAS/JAXA, as the main payload of the Korean science and technology satellite, STSAT-3. It was launched in 2013, and the space observations were made for Galactic plane survey with the Pa-α line(1.88 μm), together with cosmic infrared background investigation at high Galactic latitude using I and H band. The infrared observational data has been processed and analyzed since its launch, and the scientific results were published recently in ApJ Supplement Series and PASJ, followed by the MIRIS article introduced in the Nature Astronomy. System configuration of MIRIS is briefly presented with recent science results, and possible future works are discussed for researchers who are interested in MIRIS infrared data.
