Murata (JAXA) We will introduce scientific satellite data archiving activities in Japan, being carried out primarily at JAXA/ISAS. Since1970's, ISAS has been launching small or medium-size astronomy, solar-terrestrial physics (STP), and solar physics satellites. In 1997,ISAS has started scientific satellite data archives "DARTS" (Data Archives and Transmission System; http://darts.isas.jaxa.jp). At DARTS, we archive most ISAS satellite data taken after late 1980's. Currently, ISAS's three STP satellites, two astronomical satellites and one solar satellite are operational, and these data are being archived at DARTS. In 2003, ISAS and two other space agencies (NASDA and NAL) merged, and Japan's sole space agency "JAXA" has established. JAXA is capable of launching larger scientific satellites such as the lunar orbiting mission SELENE (SELenological and ENgineering Explorer), which is planned to be launched in August 2007. The lunar and planeta exploration is going to be one of the main projects of JAXA. We will present our plan of archiving SELENE and other future lunar and planetary data at JAXA. Space Astronomy Solar Astronomy http://darts.isas.jaxa.jp/solar http://darts.isas.jaxa.jp/astro Past and current Japanese astronomical satellite data are archived: Ginga, ASCA, Suzaku (X-rays), IRTS, Akari (infrared), HALCA (Radio) Yohkoh and Hinode solar satellite data are archived. Hinode archives will be publicly open in May 2007.

All ONC-T images & some ONC-W images NIRS: Both spectral data of Level-1 & Level-2 (in FITS format). Level-1: voltage data, Level-2: I/F (reflectance) data LIDAR: Level-2 ranging data (in ASCII format). XRS: Level-1 x-ray spectral data (in ASCII format). Histogram data of channel number & x-raycounts Yokoh daily images from 1991 September to 2000 February XRT(X-ray Telescope) Data SELENE Archives http://www.selene.jaxa.jp SELENE (SELenogical and Engineering Explore) 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.

SELENE is planned to be launched in summer 2007 Input periods Future Planetary Database at JAXA MMO VCO Click! SELENE database has been constructed by the project team. We are planning to develop a new multi-mission planetary DB based on the SELENE DB design using a PDS compatible data structure Data plots are made on the fly! DB for Heliospheric plasma sciencein cooperation with Bepi Colombo MMO “Conjunction Event Finder” at DARTS A convenient QL plot browsing tool. http://darts.isas.jaxa.jp/stp/cef/cef.cgi Choose periods (and satellite or observatories), then you can browse various kinds of data stored in the database all over the world very easily. • Bepi Colombo MMO will explore the mercury’ magnetosphere.• Contribution to ILWS is desired.• Collaboration with Solar Orbiter, Sun observations, Cross-Scale mission, etc.• Current Planetary DB (PDS) is not suitable for this topic, and the interoperability with heliospheric plasma science DB is required.• Method to realize the interoperable DB must be considered. Current Problems and Requirements • Scope of DB should include not only the public use but also use for the mission team’s data processing. - Simpler protocols are desired. Mission teams don’t want to be burdened with DB. - Sometimes, detailed access control is required. • Interoperability with neighboring science field is desired. - Existing DB resources should be inherited. - It is better to define the I/F methods for interoperability.
