It is extremely difficult to collect deep lunar soil samples during lunar exploration, as the average thickness of lunar soils is very large, and the power of lunar soil sampling systems is inherently limited.

Thermal Segregation and Reddening in Europa's Double Ridges
Abstract Europa's double ridges often display lower albedo and redder color than their surroundings. Their unique topography may cause sublimation‐driven darkening due to illumination and self‐heating—the process of thermal segregation. We apply an advanced 3D thermophysical model, including shadowing and self‐heating through mutual exchange of ...

Recognition of landslides in lunar impact craters
Landslides have been observed on several planets and minor bodies of the solar System, including the Moon. Notwithstanding different types of slope failures have been studied on the Moon, a detailed lunar landslide inventory is still pending. Undoubtedly,

Abstract Several national space agencies and commercial entities are currently targeting the Moon's south polar region for human and robotic exploration. Of particular interest are materials excavated and ejected from the Moon's largest and oldest impact structure, the South Pole‐Aitken Basin (SPA), as these ancient materials are a window into the ...

In this paper we present a crater age determination of several terrains associated with the Raditladi and Rachmaninoff basins. These basins were discovered during the first and third MESSENGER flybys of Mercury, respectively.

Impact Plasma Amplification of the Ancient Mercury Magnetic Field
Abstract Spacecraft measurements of Mercury indicate that it has a core dynamo with a surface field of 200–800 nT. These data also indicate that the northern hemisphere crust contains remanent magnetization likely produced by an ancient magnetic field. The inferred magnetization intensity is consistent with a wide range of paleofield strengths (0.2–50 ...

Abstract Dendritic valley networks on Mars have been cited as evidence for a warm and wet Noachian Mars, permitting rainfall precipitation and surface runoff. However, the climatic conditions required to sustain rainfall on early Mars remain debated.

MULTI-FACTOR ANALYSIS FOR SELECTING LUNAR EXPLORATION SOFT LANDING AREA AND THE BEST CRUISE ROUTE [PDF]
Selecting the right soft landing area and planning a reasonable cruise route are the basic tasks of lunar exploration. In this paper, the Von Karman crater in the Antarctic Aitken basin on the back of the moon is used as the study area, and multi-factor ...

MoonLITE – Technological feasibility of the penetrator concept [PDF]
Introduction: While the surface missions to the Moon of the 1960s and 1970s achieved a great deal, scientifically a great deal was also left unresolved. The recent plethora of lunar missions (flown or proposed) reflects resurgence in interest in the Moon,

Constraining the Cratering Chronology of Vesta
Vesta has a complex cratering history, with ancient terrains as well as recent large impacts that have led to regional resurfacing. Crater counts can help constrain the relative ages of different units on Vesta's surface, but converting those crater ...
