Efficient Haptic Rendering of Regolith [PDF]

2021 IEEE International Conference on Robotics and Automation (ICRA), 2021
Driven by the need for physically accurate and haptically convincing models of lunar and planetary regolith for model-mediated teleoperation in space, we present an approach to modelling regolith in an efficient yet realistic way. Model parameters are derived from physical characteristics of the regolith, to render regoliths with different density ...

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.

The circular nutrient economy of terrestrial ecosystems and the consequences for rock weathering

Frontiers in Environmental Science, 2023
Earth’s biosphere is thought to exert a substantial influence on regolith evolution and chemical weathering rates. However, ecosystems are also highly efficient at retaining and recycling nutrients.

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.

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 ...

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 ...

High‐Density Boron Nitride Nanotube Composites via Surfactant‐Stabilized Lyotropic Liquid Crystals for Enhanced Space Radiation Shielding

Advanced Functional Materials, EarlyView.
High‐density BNNT films, enabling mechanical robustness and high space radiation shielding effectiveness, are fabricated using surfactant‐stabilized BNNT liquid crystal. Simulations indicate that a 50 g cm−2 BNNT film can reduce radiation exposure by 56% compared to zero shielding, potentially doubling the duration of astronaut missions on the lunar ...
