ИСТИНА

Since the axis of rotation of the Moon is almost perpendicular to the ecliptic plane, the maxi-mum angular height of the sun above the horizon in the polar regions is negligible: 11,36° at latitude φ = ± 80° and 1,36° near the poles. It leads to appearence of permanently shadowed areas in the lunar polar regions, which can accumulate volatile compounds as proposed elear. The active impact experiment LCROSS con-firmed this idea; in addition to water vapor several oth-er volatile species were found in the impact-produced cloud over the crater Cabeus.
