Planetary Soil Simulant Characterisation: NU-LHT-2M Study Case to Support Oxygen Extraction Lab Tests with a Low-Temperature Carbothermal Process

Aerospace
Since the landing on the lunar surface, the lunar regolith has begun to interact in different ways with landed elements, such as the wheels of a rover, astronaut suits, drills, and plants for extracting oxygen or manufacturing objects.

Leadership and Accountability in Faith‐Based Institutions: Evidence From UK Mosques

Financial Accountability &Management, EarlyView.
ABSTRACT This study investigates accountability in religious institutions on the basis of evidence obtained from interviews with relevant parties in UK mosques. We mobilize prior theoretical contention regarding servant leadership and constraints on personal accountability to expose perceptions of seriously deficient discharge outcomes.

LROC NAC-derived Meter-scale Topography of the Moon’s South Polar Landing Sites: Digital Terrain Models and Their Quality Assessments

The Planetary Science Journal
High-quality digital terrain models (DTMs) are essential for lunar polar missions, aiding mission planning and surface operations. The horizontal resolution and vertical accuracy of DTMs are generally limited by factors such as source image resolution ...

Vestiges of a lunar ilmenite layer following mantle overturn revealed by gravity data

The lunar crust and mantle formed through the crystallization of a magma ocean, culminating in a solid cumulate mantle with a layer of dense ilmenite-bearing cumulates rich in incompatible elements forming above less dense cumulates. This gravitationally

Individual variability in activity patterns in Atlantic halibut (Hippoglossus hippoglossus) revealed using pop‐up satellite tags

Journal of Fish Biology, EarlyView.
Abstract Understanding fish behaviour and activity patterns is essential for interpreting their ecology and the processes that shape population dynamics, yet such information remains limited for wild fishes because observing individuals in situ is challenging.

Local Elites in Chile's Pisco Valley: Dispossession, Legal Mobilisation and Intertwined Citizenship

Journal of Agrarian Change, EarlyView.
ABSTRACT In countries in the Global South, citizenship is often closely tied to access to water and land ownership. In Latin America, the literature has primarily explored social mobilisation and identity reconfiguration in response to development‐driven processes of land and water dispossession affecting peasants, rural and Indigenous communities ...

Mid‐Infrared Compositional Spectral Parameters for the Lunar Thermal Mapper Instrument Onboard Lunar Trailblazer

Earth and Space Science
The Lunar Trailblazer mission launched in February of 2025 with the goal of characterizing lunar surface water through a targeted campaign. One instrument on the mission, the Lunar Thermal Mapper (LTM), was tasked with measuring the surface temperature ...

Identification and quantification of minerals within Apollo samples using LWIR spectroscopy

Geo-spatial Information Science
The mineral composition of the lunar surface is a critical scientific objective, as it provides key insights into the evolution of the Moon. For instance, the variations in Mg-Fe composition of pyroxene solid solution could reveal the Moon’s crustal ...

Lunar Observer Laser Altimeter observations for lunar base site selection

, 1992
One of the critical datasets for optimal selection of future lunar landing sites is local- to regional-scale topography. Lunar base site selection will require such data for both engineering and scientific operations purposes.
