Accelerated Wear Test Design Based on Dissipation Wear Model Entropy Analysis under Mixed Lubrication

open access: yesLubricants, 2022
Theoretical life prediction of tribo-pairs such as seals, bearings and gears with the failure form of wear under mixed lubrication depends on quantitative analysis of wear. Correspondingly, the wear life test depends on an accelerated wear test method to

A Review and Prospect of Appearance Defect Detection Methods for High Voltage Equipment Based on Vision Large Models

open access: yesHigh Voltage, EarlyView.
ABSTRACT High voltage equipment, as a core component of power systems, plays an indispensable role in ensuring the reliability of power supply through its safe and stable operation. Traditional visual defect detection for high voltage equipment, however, often relies on manual inspection and experience‐based judgement, which struggles to meet the ...

Automatic Crater Classification Using a Deep‐Learning‐Based Pipeline

open access: yesJournal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 5, October 2026.
Abstract Identifying and classifying impact craters on Mars is crucial for understanding the planet's geological history and surface evolution. Traditional crater classification relies on manual annotation methods, which are often limited by human biases and the difficulty of interpreting geomorphological features.

The Evolution of Autonomous Systems for Planetary Cave Exploration: A Review

open access: yesJournal of Field Robotics, Volume 43, Issue 6, Page 4094-4115, September 2026.
ABSTRACT The exploration of Subsurface Access Points (SAPs), such as lava tubes on the Moon and Mars, has gained significant interest due to their potential as stable environments shielded from surface radiation and temperature extremes. These sites are considered high‐value targets for detecting water and signs of ancient life, and assessing their ...

Topographic and Geological Factors Affecting Martian Transverse Aeolian Ridges: A Multi‐Source Remote Sensing Analysis of Morphology and Local Sediment Provenance

open access: yesEarth and Space Science, Volume 13, Issue 7, July 2026.
Abstract Transverse aeolian ridges (TARs) on Mars exhibit distinct characteristics relative to other aeolian features, yet their formation and evolutionary mechanisms remain unclear. A comprehensive investigation of TAR's distribution, morphology, composition, and environmental influences is critical for advancing our understanding of their development

The Dielectric Properties of Martian Regolith at the Tianwen‐1 Landing Site

open access: yesGeophysical Research Letters, 2023
Mars' surface is characterized by a weathered layer of regolith and exposed rock exposures that are the results of long‐term geological processes. The Mars Rover Penetrating Radar (RoPeR) on board the Zhurong rover of China's first Mars mission (Tianwen ...

Terrain Classification for Planetary Rovers Using Wireless In‐Wheel Sensor Modules and Machine Learning

open access: yesJournal of Field Robotics, Volume 43, Issue 3, Page 1884-1904, May 2026.
ABSTRACT Safe and reliable mobility over different kinds of ground is important for planetary rovers on space missions. Since terrain changes might affect the mobility of the rover, energy consumption, and safety, detecting the type of ground in real‐time is vital.

Were There Tides on Ancient Mars?

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 4, April 2026.
Abstract Tides are a key component in the Earth system as they help regulate climate and sustain life. Mars very likely had a surface ocean around 4–3 billion years ago. The NASA Curiosity Rover and the CNSA Zhurong Rover were sent to Gale Crater and the Vastitas Borealis Formation (VBF) on Mars to explore the surface and search for evidence of the ...
