Periglacial Vegetation‐Banked Terraces: A Global Survey

Permafrost and Periglacial Processes, Volume 36, Issue 4, Page 715-738, October/December 2025.
ABSTRACT Periglacial vegetation‐banked terraces (VBTs) are roughly parallel, step‐like landforms with bare treads and vegetated risers, where tread length (across‐slope) markedly exceeds tread width (downslope). Many follow the contour, but others dip off‐contour at angles of up to 40°.

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 ...

VELOX – A Demonstration Facilility for Lunar Oxygen Extraction in a Laboratory Environment [PDF]

, 2010
The ultimate goal of a permanent human presence on the Moon is discussed intensively within the global lunar community. Obviously, such an effort poses stringent demands not only on the technology but also on logistics, especially considering the ...

A Study Demonstrating That Using Gravitational Offset to Prepare Extraterrestrial Mobility Missions Is Misleading

Journal of Field Robotics, Volume 42, Issue 7, Page 3772-3794, October 2025.
ABSTRACT Recently, there has been a surge of international interest in extraterrestrial exploration targeting the Moon, Mars, the moons of Mars, and various asteroids. This contribution discusses how current state‐of‐the‐art Earth‐based testing for designing rovers and landers for these missions currently leads to overly optimistic conclusions about ...

Photometry of Lunar Swirls in Comparison to Fresh Crater Ejecta

The Planetary Science Journal
Swirls are sinuous high-reflectance lunar surface features collocated with crustal magnetic anomalies. These bright features and their geographical relationship to magnetic anomalies have been studied for decades, although their cause remains unclear ...

Structural Analysis of Lunar Regolith from LPR CH-2 Data Based on Adaptive f-x E MD: LPR Data Processed by Adaptive f-x EMD

Advances in Astronomy, 2019
The Lunar Penetrating Radar (LPR) is one of the important scientific payloads in China’s Chang’E-3 (CE-3) to image within 100 m below the lunar surface. The acquired LPR data is significant for the research of lunar geological structure.

Regolith thermal energy storage for lunar nighttime power [PDF]

A scheme for providing nighttime electric power to a lunar base is described. This scheme stores thermal energy in a pile of regolith. Any such scheme must somehow improve on the poor thermal conductivity of lunar regolith in vacuum. Two previous schemes

(3200) Phaethon: Bulk density from Yarkovsky drift detection

, 2018
The recent close approach of the NEA (3200) Phaethon offered a rare opportunity to obtain high-quality observational data. We used the newly obtained optical light curves to improve the spin and shape model of Phaethon and to determine its surface ...

The Utility of a Hyperspectral Infrared Imager for Crewed Exploration of Planetary Bodies

Earth and Space Science, Volume 12, Issue 10, October 2025.
Abstract Planetary analog simulations are a powerful exercise for understanding the utility of deployable instruments, their operational protocols, and the visualization of data products during ExtraVehicular Activities (EVAs). This paper presents results of a field campaign by the NASA Solar System Exploration Research Virtual Institute (SSERVI ...
