A review of lunar penetrating radar data-driven research in the Chang'e-4 landing area

地球与行星物理论评
The Chang'e-4 lunar penetrating radar (LPR) has achieved the first in-situ high-resolution detection of the shallow subsurface structure on the far side of the Moon, filling a critical gap in our understanding of the lunar far side's subsurface ...

Electromagnetic Simulations of Ground-Penetrating Radar Propagation near Lunar Pits and Lava Tubes [PDF]

Placing an Orion capsule at the Earth-Moon L2 point (EML2) would potentially enable telerobotic operation of a rover on the lunar surface. The Human Exploration Virtual Institute (HEVI) is proposing that rover operations be carried out near one of the ...

The Lunar Regolith Thickness and Stratigraphy of the Chang’E-6 Landing Site

Remote Sensing
The Chang’E-6 (CE-6) mission successfully returned 1935.3 g of lunar soil samples from the Apollo basin within the South Pole–Aitken basin. One of its scientific objectives is to investigate the subsurface structure and regolith thickness at the landing ...

A radar-echo model for Mars [PDF]

Researchers developed a radar-echo model for Mars based on 12.6 cm continuous wave radio transmissions backscattered from the planet. The model broadly matches the variations in depolarized and polarized total radar cross sections with longitude observed

Gully Formation at the Haughton Impact Structure (Arctic Canada) Through the Melting of Snow and Ground Ice, with Implications for Gully Formation on Mars [PDF]

The formation of gullies on Mars has been the topic of active debate and scientific study since their first discovery by Malin and Edgett in 2000. Several mechanisms have been proposed to account for gully formation on Mars, from dry mass movement ...
