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)
We determined model ages of mare deposits on the farside of the Moon on the basis of the crater frequency distributions in 10-meter-resolution images obtained by the Terrain Camera on SELENE (Selenological and Engineering Explorer) (Kaguya). Most mare volcanism that formed mare deposits on the lunar farside ceased at approximately 3.0 billion years ago,(More)
4–6 suggested several possible olivine-bearing sites, but one of the candidate occurrences of olivine was later reclassified , on the basis of continuous reflectance spectra over the entire 1 µm band, as a mixture of plagioclase and pyroxene 7. Here we present a global survey of the lunar surface using the Spectral Profiler onboard the lunar explorer(More)
[1] We present details of the identification of sites that show an absorption band at visible wavelengths and a strong 2 m band using the SELENE Spectral Profiler. All the sites exhibiting the visible feature are found on the regional dark mantle deposit (DMD) at Sinus Aestuum. All the instances of the visible feature show a strong 2 m band, suggestive of(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)
The inside of Shackleton Crater at the lunar south pole is permanently shadowed; it has been inferred to hold water-ice deposits. The Terrain Camera (TC), a 10-meter-resolution stereo camera onboard the Selenological and Engineering Explorer (SELENE) spacecraft, succeeded in imaging the inside of the crater, which was faintly lit by sunlight scattered from(More)
The distribution and the geological context of the olivine-rich exposures in the South Pole-Aitken (SPA) Basin on the Moon were investigated based on the spectral data obtained from the Spectral Profiler (SP) and Multiband Imager (MI) onboard the Japanese lunar explorer Kaguya/SELENE. The olivine-rich exposures are found only in the peak rings or central(More)
[1] We present a new global survey of the purest anorthosite (PAN) rock using the Spectral Profiler onboard Kaguya. We found that PAN rocks are widely distributed over the Moon, including the Feldspathic Highland Terrain and the south and north polar regions. All PAN sites are associated with huge impact structures with diameters larger than 100 km. Based(More)
Japanese Moon explorer SELENE (KAGUYA) completed its nominal observation period of about one-year from December 2007 and entered the extended-mission period that is expected to be about a half year using surplus fuel. During the SELENE nominal mission period, the push-broom Terrain Camera (TC) [1] aboard KAGUYA, successfully acquired 10 m-resolution(More)
