Lunar Terahertz SUrveyor for KIlometer-scale MappIng: TSUKIMI is a share-riding minisatellite to observe Terahertz-wave thermal emission from circular orbit for understanding of chemical/physical compositions and water cycle process at surfaces/subsurface of Moon. TSUKIMI employed two terahertz-wave heterodyne receivers, each of them are H/V polarized, in the frequency ranges around 250 and 500GHz. The sensor instrument and satellite is developing togather and now in the phase between conceptual examination and BBM. This presentation will address the science objectives, the technology challenges and recent break-throughs, the instrument hardware development status and future plans.
