Abstract

The status of the X-ray spectrometer XRS onboard SELENE (Kaguya) is reported. The XRS is to map major elemental composition of lunar surface but is subject to instrumental trouble and unexpectedly faint solar activity. However it observed X-rays from the onboard standard sample excited by solar X-rays and non-solar X-ray events, maybe by particle events.
