Meter‐Scale Roughness of the Lunar Surface
Abstract Small‐scale surface roughness is a key indicator of local geological processes, yet it has not previously been mapped globally on the Moon. We present global meter‐scale surface roughness maps generated from the Lunar Orbiter Laser Altimeter pulses, which record information about surface undulations within the instrument's ∼5 m individual ...

Magma Activity History and Formation Mechanism of Lacus Somniorum, the Largest Lunar Lacus
Lacus Somniorum, the largest lacus-type volcanic plain on the Moon, lies outside major impact basins and provides a key test case for understanding nonbasin mare formation.

Abstract Recent works suggest there are periods when the Sun encountered massive interstellar cold clouds which compressed the heliosphere to within Earth's orbit, exposing Earth to interstellar galactic cosmic rays and energetic particles of heliospheric origin.

Dust Plumes Induced by a Time‐Varying Electron Beam
Abstract We present laboratory results to address dust charging and lofting on the Moon and other airless planetary bodies in response to time‐varying solar wind and ultraviolet (UV) exposure. In these experiments, dust is exposed to an electron beam that varies in beam energy between 40 and 260 eV as a function of time.

Meter‐Scale Lunar Dust‐Bed Charging and Local Apparent Dust Release Under Ultraviolet Irradiation
Abstract Vacuum ultraviolet (VUV) irradiation charges lunar regolith and may contribute to electrostatic dust mobilization, but meter‐scale laboratory constraints remain limited. We developed a meter‐scale deuterium‐lamp‐array VUV system that combines optical‐path superposition and stable array stitching to produce a controlled lunar‐relevant photon ...

Potential Links Between Physiological and Perceptual Strain in High Heat Stress
ABSTRACT The physiological strain index (PhSI) is widely used to quantify thermoregulatory and cardiovascular strain during heat stress. However, direct physiological measurements may not always be feasible in occupational or athletic settings.

From net sink to episodic source: Seasonal dissolved inorganic carbon budget in an intertidal basin
Abstract The back‐barrier basin of Spiekeroog in the East Frisian Wadden Sea is a biogeochemically dynamic intertidal system that plays a key role in regulating coastal carbon fluxes and regional dissolved inorganic carbon (DIC) budgets. Compared to total alkalinity, DIC fluxes in this region remain poorly quantified, limiting a comprehensive ...

Estimating the critical angle of top near‐surface layers on the Moon
Abstract Near‐surface characterization of the lunar subsurface is essential for future exploration and infrastructure development, particularly for the construction of underground habitats that provide protection against radiation and micrometeorites. However, conventional seismic approaches for estimating subsurface properties typically rely on prior ...

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 ...
