The Japan Aerospace Exploration Agency (JAXA) verified Multiband Imager (MI) onboard the lunar explorer "KAGUYA" (SELENE) orbiting approximately 100km above the lunar surface, through initial observations on November 3, 2007 and subsequent data analysis.

The Multiband Imager (MI) is observation instrument to measure mineral distribution by analyzing the reflection of nine observation bands of visible to near infrared wavelengths. Early data analysis results of MI data shows the volume and scattered direction of material dug up to the surface from the inside and chemical composition of materials existing underneath craters.

The composition data by using multi band data of MI also shows more clear information about the inconsistency of the distribution of material scattered around the crater than the one from a single-band data although the analysis data was not calibrated yet. The red to yellow (then yellow-green) areas indicate that more dub-up material existence because of highlands anorthosite surface soil (in dark blue) for crater generation.
