It has been thought that the lunar highland crust was formed by the crystallization and floatation of plagioclase from a global magma ocean, although the actual generation mechanisms are still debated. The composition of the lunar highland crust is therefore important for understanding the formation of such a magma ocean and the subsequent evolution of the(More)
[1] The Spectral Profiler (SP) onboard the Japanese SELENE (KAGUYA) spacecraft is now providing global high spectral resolution visible-near infrared continuous reflectance spectra of the Moon. The reflectance spectra of impact craters on the farside of the Moon reveal lithologies that were not previously identified. The achievements of SP so far include:(More)
There are two major freely available global digital elevation datasets, known as GTOPO30 and SRTM. To know the accuracies of those data in global scale, relative evaluation of these data and validation with global scale are performed. We compared elevation values of GTOPO30 and SRTM 30 arc second datasets globally and found there are places in the world(More)
Introduction: Location information is an essential key for all data of lunar and planetary science. Recent maps are generally web based and these systems are generally called as Web-GIS (Geographical Information System). Web-GIS is becoming common in lunar and planetary field such as USGS Map-a-Planet [1]. However, some features should be required with(More)
This paper presents an experimental study with a hybrid microgrid system, which is proposed and implemented in the Tagajo campus of Tohoku Gakuin University, Japan. The developed microgrid consists of renewable power generations of PV and wind power generator, two types of energy storage devices of secondary battery and EDLC (Electrical Double-layer(More)
