Distinct element method for static and flow mobility characteristics of lunar regolith based on particle shape characteristics

Yantu gongcheng xuebao
Since it exhibits uniquely grain shape, physical and mechanical characteristics, the lunar regolith is extremely important for utilization of in-situ resources, selection of base station location and construction in lunar exploration.

Computational Analysis of the Vibrational Response of Lunar Regolith Made of Nonspherical Grains

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT Vibration‐based systems have shown that appropriately oriented and tuned mechanical oscillations can disrupt regolith interlocking and promote flow. Building on this evidence, the present study investigates vibration‐controlled granular discharge as a potential ISRU (In Situ Resource Utilization) strategy, with the aim of supporting ...

Damage constitutive model of lunar soil simulant geopolymer under impact loading

Journal of Rock Mechanics and Geotechnical Engineering
Lunar base construction is a crucial component of the lunar exploration program, and considering the dynamic characteristics of lunar soil is important for moon construction. Therefore, investigating the dynamic properties of lunar soil by establishing a

An Open Database of Lunar Regolith and Simulants Properties

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT Lunar regolith, the layer of unconsolidated material covering the Moon's surface, is central to the science and technology developed for the Moon, notably related to in‐situ science investigations, resource utilization, surface infrastructure, and mobility systems.

A 3D hybrid simulation study of the electromagnetic field distributions in the lunar wake [PDF]

, 2011
As a consequence of its lack of a thick atmosphere and an ionosphere, the interaction of the solar wind with the Moon is characterized by the direct impact of the solar wind on its sunward hemisphere.

Interplanetary frontiers: terraforming from an invasion science perspective

Oikos, EarlyView.
The pursuit of a multi‐planetary existence represents one of humanity's greatest frontiers. If applied justly, it offers an opportunity to extend its civilization's lifespan amid escalating sustainability crises on Earth. One approach increasingly gaining traction is terraforming, a hitherto theoretical ecological and evolutionary experiment revolving ...

Do cultural taboos regulate hunting in transitioning Indigenous communities? The case of the Idu Mishmi of Northeast India

People and Nature, EarlyView.
Abstract There is rising recognition of resource‐use rights of Indigenous Peoples and Local Communities (IPLCs) within wildlife conservation. Historically, sociocultural institutions ensured wildlife sustainability in many IPLC areas. However, the future viability of such institutions is uncertain as IPLCs change in response to external pressures and ...

Relational knowing as method and practice

People and Nature, EarlyView.
Abstract This paper seeks to contribute to (re)building the capacity for embodied, place‐based relational knowing, transforming how we know and thus what we know. What is known, or sought to be known, is relations. How we know these relations is by already being in it: breathing, sensing, moving, listening, responding, affecting and being affected ...

Hexapod Locomotion Across Structured and Unstructured Terrains: A Data‐Driven Review of Modeling, Control, and Validation

Journal of Field Robotics, EarlyView.
ABSTRACT The design of a hexapod is complex and requires integration between kinematic models, control systems, and sensing. Existing literature has reviewed these sub‐systems in isolation. Since 2021, there has been no review of the field despite significant advancements in soft soil, lunar traversal, and artificial intelligence.
