The sunlit conditions of the lunar polar regions were estimated by using a digital elevation model made by the laser altimeter data onboard the Japanese lunar orbiter KAGUYA (SELENE). The result shows that i) there are no peaks of eternal light in either north or south polar regions, ii) most continuously lit surfaces are 89% for north and 86% for south, iii) there are permanently shadowed regions. These information will be useful for the long-durable landing experiments on the Moon and possibly for the human activity on the Moon in the near future.

    • ...Orbit precision for the SELENE main orbiter has been assessed in the context of topography applications (Noda et al. 2008; Araki et al. 2009), but in those results only twoway data were used, resulting in an overall orbit precision of around 50 m, but with notable outliers...
    • ... outlying arcs in January stretch the overall total value to 64 m. The upper limit from orbit overlaps is close to the RMS of crossover difference values as listed in Table 2, although these are consistently higher, at 24 m. As shown in Fig. 6, when using only two-way data certain orbit geometries (in this case, edgeon orbits) show a bad consistency, which was also found when applying the orbit solutions in a topography application (Noda et al. ...

    • ...Recently, the lighting conditions at the south pole have been extensively studied with the Kaguya altimeter data [Noda et al., 2008], and by the Earth‐based Goldstone Solar System Radar [Bryant ,2 010], though the latter is plagued by large gaps in spatial coverage due to poor geometric viewing conditions...
