SELENE(Kaguya) PDS3 Released

The lunar orbiter "SELENE (Kaguya)", which was launched in September 2007, continuously obtained scientific data, just until it impacted on the moon's surface in June 2009. We have released these datasets from the "SELENE L2DB system" since November 2009. Although its data format was designed based on NASA 's Planetary Data System version 3 (PDS3), it was slightly different from the original PDS3 standard. Consequently, PDS3 standard tools were not fully applicable. Also, since the data and system were closely coupled in the L2DB system, the data distribution had to be stopped due to system maintenance etc.
Envisioning long-term archiving of the Kaguya data, we have (1) improved conformity to the PDS3 standard and (2) loosely coupled system and data to solve these problems (L2DB service was discontinued after Sep. 30). Thanks to the new development, PDS3 standard tools are now applicable. Also, it has become possible to separate managements of the system and data with different update frequencies. The figures in the right-hand side are Kaguya PDS3 images displayed by three different standard tools; NASAView by NASA, ISIS qview by USGS, and QGIS, which is popular in earth observations. Kaguya PDS3 data can be downloaded from http://darts.isas.jaxa.jp/pub/pds3 as well as other PDS3 data of different satellites and/or instruments. (Oct 2017)


Magnetic field experiment data taken by Sakigake released

At ISAS, we are continuously collecting those data taken by past ISAS missions, and kept at Japanese universities. The dataset of the Interplanetary Magnetic Field experiment (IMF) and Orbit data onboard Sakigake is now available on DARTS. Sakigake, launched in 1985, was one of the twin spacecraft (the other is Suisei) sent to explore Comet Halley approached in 1986; Sakigake became the first Japanese "artificial planet". Three experiments were mounted on Sakigake, Solar-wind ion detector (SOW), Plasma-wave probe (PWP), and Interplanetary magnetic field measurement (IMF). It detected hydromagnetic waves generated by water group ions originating from the comet. Through collaboration with Tohoku Institute of Technology, those precious data kept at the university were made publicly available at DARTS. (Aug 2017)
