Observations of the subsurface geology of the Moon help advance our understanding of lunar origin and evolution. Radar sounding from the Kaguya spacecraft has revealed subsurface layers at an apparent depth of several hundred meters in nearside maria. Comparison with the surface geology in the Serenitatis basin implies that the prominent echoes are probably from buried regolith layers accumulated during the depositional hiatus of mare basalts. The stratification indicates a tectonic quiescence… 

Distribution of the subsurface reflectors of the western nearside maria observed from Kaguya with Lunar Radar Sounder

The Lunar Radar Sounder (LRS) performed global soundings and detected possible subsurface echoes at the nearside maria. This paper examines the relationship between the distribution of the detected

Lunar Radar Sounder Observations of Subsurface Geology and Natural Waves

Observations by Lunar Radar Sounder (LRS) onboard KAGUYA (SELENE) have revealed subsurface layers at an apparent depth of several hundred meters in nearside maria. Comparison with the subsurface

Identification of buried lunar impact craters from GRAIL data and implications for the nearside maria

Gravity observations from the dual Gravity Recovery and Interior Laboratory (GRAIL) spacecraft have revealed more than 100 quasi‐circular mass anomalies, 26–300 km in diameter, on the lunar nearside.

Lunar Seismic Tomography and the Early Earth

Seismic tomography reveals significant lateral heterogeneities in the lunar interior. A correlation is found between S-wave velocity tomography and distribution of thorium. The area with a high

Seismic tomography of the Moon

We attempted to determine the first three-dimensional P and S wave velocity and Poisson’s ratio structures of the lunar crust and mantle down to 1000 km depth under the near-side of the Moon by

First look by the Yutu-2 rover at the deep subsurface structure at the lunar farside

The authors here report results from the ground-penetrating radar onboard the Yutu-2 rover from the Chagn’E 4 mission, which presents up to 330 m deep subsurface structure of the Von Karman Crater inside the South Pole Aitken Basin.

The Moon’s farside shallow subsurface structure unveiled by Chang’E-4 Lunar Penetrating Radar

The CE-4 LPR images provide clear information about the structure of the subsurface, which is primarily made of low-loss, highly porous, granular materials with embedded boulders of different sizes; the images also indicate that the top of the mare basal layer should be deeper than 40 m.

Lunar regolith and substructure at Chang’E-4 landing site in South Pole–Aitken basin

The South Pole–Aitken (SPA) basin is the oldest and largest impact structure on the Moon, and it gives particular insight on the lunar interior composition 1 – 3 . However, the surface of the SPA

Radar Soundings of the Subsurface of Mars

Data from the northern lowlands of Chryse Planitia have revealed a shallowly buried quasi-circular structure about 250 kilometers in diameter that is interpreted to be an impact basin and a planar reflector associated with the basin structure may indicate the presence of a low-loss deposit that is more than 1 kilometer thick.

Accumulation and Erosion of Mars' South Polar Layered Deposits

The sounding radar SHARAD on the Mars Reconnaissance Orbiter mapped detailed subsurface stratigraphy in the Promethei Lingula region of the south polar plateau, Planum Australe, indicating recent erosion of ice-rich layered deposits.

Radar Sounding of the Medusae Fossae Formation Mars: Equatorial Ice or Dry, Low-Density Deposits?

The Mars Advanced Radar for Subsurface and Ionospheric Sounding (MARSIS) instrument aboard the Mars Express Spacecraft has detected nadir echoes offset in time-delay from the surface return in orbits over MFF material, interpreted to be from the subsurface interface between the M FF material and the underlying terrain.
