Optimal Radio Window for the Detection of Ultra-High-Energy Cosmic Rays and Neutrinos off the Moon [PDF]

, 2005
When high-energy cosmic rays impinge on a dense dielectric medium, radio waves are produced through the Askaryan effect. We show that at wavelengths comparable to the length of the shower produced by an Ultra-High Energy cosmic ray or neutrino, radio ...

Bulk Density of the Lunar Regolith at the Chang'E‐3 Landing Site as Estimated From Lunar Penetrating Radar

Earth and Space Science, 2020
Bulk density of the lunar regolith is a key factor affecting its geophysical and geotechnical properties. In this study, a new method for estimating the bulk density of the lunar regolith is developed based on the geometric characteristic (i.e ...

Lunar ISRU Energy Storage and Electricity Generation [PDF]

, 2020
The survival of the astronauts and their equipment is the priority for any long-term exploration mission to the Moon. The provision of energy during the long lunar nights is a critical part of these missions.

Effect of Target Properties on Regolith Production

Remote Sensing
Based on the measurements of regolith thicknesses on the lunar maria (basalts), the lunar regolith was determined to have accumulated at a rate of about 1 m/Gyr since the era of the late heavy bombardment.

Deep dielectric charging of regolith within the Moon\u27s permanently shadowed regions [PDF]

, 2014
Energetic charged particles, such as galactic cosmic rays (GCRs) and solar energetic particles (SEPs), can penetrate deep within the lunar surface, resulting in deep dielectric charging.

Making parts on Mars: Laser processing of iron contaminated by regolith simulant

Materials Today Advances
Manufacturing pure metals on Mars is challenging due to limited energy resources and unavoidable contamination of raw materials and production equipment with the Martian dust (regolith) resulting in impure materials.

The stratification of regolith on celestial objects

, 2015
All atmosphere-less planetary bodies are covered with a dust layer, the so-called regolith, which determines the optical, mechanical and thermal properties of their surface.

A multidisciplinary study of an exceptional prehistoric waste dump in the mountainous inland of Calabria (Italy) : implications for reconstructions of prehistoric land use and vegetation in Southern Italy [PDF]

, 2020
The mountainous inland of northern Calabria (Southern Italy) is known for its sparse prehistoric human occupation. Nevertheless, a thorough multidisciplinary approach of field walking, geophysical survey and invasive research led to the discovery of a ...

Structure and Formation Mechanism of Lunar Regolith

Space: Science & Technology
Lunar regolith is a thin layer of weakly cohesive detrital materials covering the lunar surface. Studies on returned lunar samples have revealed that the lunar regolith mainly consists of fragments of rocks, minerals, breccia, glasses, and agglutinates ...

Measurements of thermal properties of icy Mars regolith analogs [PDF]

, 2012
In a series of laboratory experiments, we measure thermal diffusivity, thermal conductivity, and heat capacity of icy regolith created by vapor deposition of water below its triple point and in a low pressure atmosphere.
