- Abstract
SELENE is the most sophisticated lunar exploration mission in the post-Apollo Era. SELENE consists of the main orbiter and two small satellites (the Relay satellite and the VRAD satellite). The main orbiter will observe the distribution of the elements and minerals on the surface, the surface and sub-surface structure, the gravity field, the remnant of the magnetic field and the environment of energetic particles and plasma of the Moon. The Relay satellite will relay the Doppler ranging signal between the Main Orbiter and the ground station for the world’s first direct measurement of he gravity field in the far side of the Moon. The differential VLBI Radio-Sources on board the Relay satellite and the VRAD satellite are used to determine the gravity field of the Moon most precisely. SELENE data will be used for studying “lunar origin and evolution” and “exploration” of the Moon and will be archived and distributed in PDS-like format with the descriptions of data format and technical information (data format description is planning to be ready by the launch.) SELENE Level-2 processed data will be archived in “Level-2 Data Archive and Distribution System” (L2DB) at SOAC (SELENE Operation and Analysis Center) at Sagamihara-campus in JAXA. Users can search and download Level-2 processed data via Web browser. SELENE data will be available for users through the internet. 1 year after the nominal mission phase (about 2 years after the SELENE launch). The SELENE L2 DB HP Web site (under construction) will be linked to the SELENE HP. This paper describes the overview of SELENE ground system and data delivery plan.
