At an altitude of 100 km, this equals 5 m – about the size of a two-car garage. It also measured the heights of lunar features to an accuracy of 10 m – the height of a three-story apartment building. One goal of the TMC team was to produce maps of the Moon’s polar regions. The biggest problem was that very little light falls there. In essence, these areas are very dark.

The shadows are different in these positions. Different viewing angles cause this. Indian astronomers constructed maps of most of the north and south polar regions of the Moon from TMC images. Over 80% of the areas south of 85°S and north of 85°N are in these maps. htm. 13. 1 W) X-ray spectrometer Image the Moon’s surface at different wavelengths Sreekumar et al. (2009) Kumar et al.
