The Constraint of Crewed Mars Missions Based on Current Radiation Dose Measurements

Space Weather, Volume 24, Issue 3, March 2026.
Abstract Crewed missions to Mars will be a milestone of future space exploration programs. However, the absence of Earth's magnetic field leaves astronauts directly exposed to unattenuated energetic particles in deep space, primarily galactic cosmic rays (GCRs), resulting in significantly higher radiation levels and enhanced health risks.

Irrigation Monitoring With Cosmic‐Ray Neutron Sensors: Unraveling Field Experiments With Neutron Transport Simulations

Water Resources Research, Volume 62, Issue 3, March 2026.
Abstract Irrigation is essential for stabilizing yields and sustaining food production, yet it faces increasing challenges, especially in water‐scarce regions. Cosmic‐ray neutron sensors (CRNS) are a promising tool in irrigation management as they can continuously monitor soil water content (SWC) over large areas.

Bright Monocompound Metal Halide Scintillator for Fast Neutron Radiography

Advanced Functional Materials, Volume 36, Issue 3, 8 January 2026.
Metal halide scintillator, tetraphenylphosphonium manganese bromide (TPP2MnBr4), provides a significant benefit for fast neutron imaging. A fourfold increase in efficiency over traditional zinc sulfide screens is achieved by efficiently utilizing neutron interactions within its homogeneous structure.

Holocene Glacial–Paraglacial–Periglacial Transitions of a Sub‐Arctic Glacial Cirque, Fremri‐Grasárdalur, Northern Iceland

Permafrost and Periglacial Processes, Volume 37, Issue 1, Page 78-106, January/March 2026.
ABSTRACT The aim of this work is to study a variety of glacial, periglacial and paraglacial features found in a small cirque, Fremri‐Grasárdalur, in Tröllaskagi (Northern Iceland). We implement a multidisciplinary approach combining high‐resolution geomorphological mapping, horizontal/vertical boulder displacement (from 1994 to 2019) and surface ...
