Groundwater at the southern pole of the Moon via the gravity strike angles: IM-1 and Artemis

Popis výsledku v původním jazyce

Gravity strike angles are one of the gravity aspects. They are computed from global static gravity field models. They react to changes in density variation and porosity. Internal rock anisotropy and stresses can be detected by strike angles. They run parallel with the direction of weakness in the strength of the rock, e.g., the direction schistosity and/or the presence of faults or micro-fault zones. Thus, they can help to describe the underground causative body in another way than traditional gravity anomalies. We used the GRGM1200A gravity field model for the Moon to the degree and order of 600 in spherical harmonic expansion and LOLA topography. The results show that the strike angles are more frequently and more intensively aligned (combed) near the poles than in other places. The strike angles are highly combed for the Malapert A crater (the landing site of IM-1/Odyssey) as well as for the localities selected by NASA for the forthcoming Artemis missions. Our method, which has already been applied many times on diverse geological features on the Earth, provides quick and cheap remote sensing procedure, a preliminary diagnostic tool, independent of all others, in search of lunar water.
