Modeled Subsidence of Permafrost Terrain 2025–2050: North‐Central Alaska

Permafrost and Periglacial Processes, Volume 37, Issue 4, Page 692-712, October/December 2026.
ABSTRACT A large fraction of the Alaska terrain is underlain by regolith that contains excess ice (ice that in volume exceeds the natural pore space). Possible loss of excess ice would lead to ground subsidence, which in turn would disturb and destabilize the ground surface.

From Flybys to Sample Return: A Review of Space Probes and Robotic Sampling Technologies for Small Bodies

Journal of Field Robotics, Volume 43, Issue 7, Page 4475-4514, October 2026.
ABSTRACT As a crucial puzzle piece of deep space exploration, exploring small bodies can provide significant scientific insights and valuable mineral resources. Unlike missions to the Moon and Mars, small‐body missions pose distinct technical challenges, including communication delays, weak gravity, and uncertain environments. This paper reviews a full

Mapping the Western Jezero Crater Rim From Orbit: Connections to Regional Geologic Units and Context for Exploration by the Mars 2020 Perseverance Rover

Journal of Geophysical Research: Planets, Volume 131, Issue 10, October 2026.
Abstract The Mars 2020 rover is currently traversing the western rim of Jezero, a Middle to Late Noachian‐aged crater formed by an impactor that struck the northwest edge of Isidis Planitia (hereafter referred to as the Isidis basin) on Mars. Previous studies suggest that pre‐Isidis basin and Noachian outcrops are preserved throughout this region ...

Ground-penetrating radar investigation of regolith thickness on a periglacial alpine summit flat, Uinta Mountains, Utah, USA

Arctic, Antarctic, and Alpine Research
Summit flats are low-relief, gently sloping landforms common in periglacial mountain environments. Apart from at their edges where summit flats are truncated by glacial headwalls and at their crests where isolated tors are occasionally present, bedrock ...

Modeling the Redistribution of Dust Across the Martian Surface for Mars Years 24 to 36

Journal of Geophysical Research: Planets, Volume 131, Issue 10, October 2026.
Abstract Global Dust Events (GDEs) transport huge amounts of dust across the Martian atmosphere. GDEs occur only every few Mars Years (MYs), but the reasons behind this inter‐annual variability remain poorly understood. The question whether surface dust exhaustion and subsequent replenishment explain this variability remains open.

Spatiotemporal Dynamics of Active Root Zone Storage Revealed From Hybrid Machine Learning

Water Resources Research, Volume 62, Issue 10, October 2026.
Abstract Water within the root zone regulates water, energy, and carbon exchanges at the land‐atmosphere interface, yet the dynamically active portion of subsurface water that ecosystems mobilize for evapotranspiration (ET) remains unclear, because it represents only part of the total subsurface storage.

Radiation Exposure and Shielding Effects on the Lunar Surface

Space Weather
The Moon will be a primary target for human space exploration in the near future. A limiting factor for a crewed mission to the Moon is the radiation dose during their stay on the lunar surface.

Determination of the Dynamic Angle of Repose of Lunar Regolith Simulants

Geosciences
The determination of the dynamic angle of repose (DAR) of lunar regolith simulants is essential for modeling material behavior during in situ resource utilization (ISRU) processes and lunar surface operations.

Performance of hydrogen-rich materials in combination with lunar regolith for shielding against GCR, albedo, and SPEs on the surface of the moon studied using MULASSIS [PDF]

AIP Advances
The moon is the most likely location for future human habitation. The radiation exposure from the combination of galactic cosmic rays, solar particle events, and albedo radiation on the Moon’s surface is one of the major obstacles to permanent settlement
