and technology development. The launch was rescheduled last summer in the rearrangement of HII-A launch schedule. The main objective of the mission is to study the origin and evolution of the Moon. The spacecraft consists of a main orbiter at about 100 km altitude in the polar circular orbit and two subsatellites in the elliptical orbits with the apolune at 2400 km and 800 km. The main orbiter will carry instruments for scientific investigation including mapping of lunar topography and surface composition, measurement of the magnetic fields, and observation of lunar and solar terrestrial plasma environment. The mission period will be one year. If extra fuel is available, the mission will be extended. The elemental abundances are measured by the x-ray and gamma-ray spectrometers. Alpha particles from the radon gas and polonium are detected by an alpha particle spectrometer. The mineralogical characterization is performed by a multi-band imager. The mineralogical composition is identified by a spectral profiler, a continuous spectral analyzer. The surface topographic data are obtained by a high resolution terrain camera and a laser altimeter. The inside structure up to 5 km below the lunar surface is observed by the radar sounder experiment using a 5 MHz radio wave. The magnetometer provides data on the lunar surface magnetic field which will be used to understand the origin of lunar paleomagnetism and paleomagnetism. Doppler tracking of the orbiter via the relay satellite when the orbiter is in the far side is used to determine the gravity field of the far side. Radio sources on the two subsatellites are used to conduct the differential VLBI observation from ground stations. The lunar environment of high energy particles, electromagnetic fields, and plasma, is also measured by the main orbiter. The radio science using coherent x and s band carriers from the orbiter will be conducted to detect the tenuous lunar ionosphere. For the solar-terrestrial plasma observation, an imaging observation of the earth will be made to clarify the macroscopic dynamics of the terrestrial plasma environment and aurora activities. The observation of planetary radiation from the Jupiter and Saturn is also planned. Besides the scientific instruments, a high definition camera system to observe the earth and lunar surface will be onboard for publicity. A mission operation and data analysis center for SELENE is now under development. All scientific data are stored and some of them are transmitted to the PI team members outside the center for operation monitor and data analysis. Data will be open to the public one year after completion of the nominal mission.
