The six statistically most stable spots with the lowered neutron flow were revealed by the LEND neutron spectrometer installed on board the LRO spacecraft in the both lunar polar regions. Five spots are located near the South Pole of the Moon and one - near the North Pole. Only one of the above spots - NSR S5 (center coordinates ~ 83º S, 30º E) - is located in the Luna - Glob spacecraft landing area (sector boundary 70º S - 85º S, 0º E - 60º E, planned by Roscosmos in 2019. In the present study, we investigated the illumination conditions, temperature regime and the possibility of existence of deposits of volatile compounds, similar to those found at the site of LCROSS probe fall in the crater Cabeus (85.2 ° S, 42.1 ° E, D = 100.6 km), such as H2O, H2S, NH3, SO2, C2H4, CO2, CH3OH, CH4 and CO in vicinity NSR S5 spot.
