Press Release: KAGUYA (SELENE) Observations with Laser Altimeter (LALT) and Lunar Radar Sounder (LRS) Sounder Mode
Quote:
Through analysis of the LALT data taken from November 26 (Japan Standard Time, all the following dates and times are JST), 2007, we confirmed that the lunar topography can be deduced as planned. The LALT is expected to obtain a global and precise topographic data set of the Moon, including the polar regions with a latitude higher than 75 degrees that have never been explored by previous satellites. This data set, in combination with the high-spatial-resolution stereoscopic observation data to be taken with the Terrain Camera (TC), will compose the first complete, precise, and high-spatial-resolution topographic map of the Moon.
The LRS sounder mode was tested on November 20 and 21, 2007, over the eastern Mare Imbrium, and the performance of this mode was verified. The data obtained in this experiment visualized largely horizontal subsurface stratification, which probably consists of alternating beds of lava, volcanic ashe and ejecta blankets. The existence of such a strata has been expected for decades based chiefly on surface geology. By means of global scanning, the LRS will provide us with a massive amount of information on the subsurface geology of the Moon down to a few kilometers from the surface. Faults and folds, identified from the discontinuity or disturbance of subsurface stratification, are important clues to understand not only regional tectonics but also the evolution of the Moon, including global thermal history.
