Vision-Based Decision Support for Rover Path Planning in the Chang’e-4 Mission

Remote Sensing, 2020
In planetary rover missions, rover path planning is critical to ensure the safety and efficiency of the rover traverse and in situ explorations. In the Chang’e-4 (CE-4) mission, we have proposed and developed vision-based decision support methods ...

Spaceborne and spaceborn: Physiological aspects of pregnancy and birth during interplanetary flight

Experimental Physiology, EarlyView.
Abstract Crewed interplanetary return missions that are on the planning horizon will take years, more than enough time for initiation and completion of a pregnancy. Pregnancy is viewed as a sequence of processes – fertilization, blastocyst formation, implantation, gastrulation, placentation, organogenesis, gross morphogenesis, birth and neonatal ...

Obstacle-climbing capability analysis of six-wheeled rocker-bogie lunar rover on loose soil

, 2009
Taking six-wheeled rocker-bogie lunar rover as an object, on the basis of force analysis between the wheels and lunar soil, its obstacle-climbing force model on loose soil was established in this paper, and the wheel sinkages were obtained.

Effects of 14 days of head‐down bed rest with or without exercise, and subsequent recovery on bone turnover, density and structure in older adults

Experimental Physiology, EarlyView.
Abstract Bed rest accelerates bone loss and may exacerbate skeletal fragility. This study examined the effects of 14 days of head‐down tilt bed rest (HDBR) with or without exercise, and subsequent recovery, on bone turnover, density and structure in older adults. Twenty‐two healthy older adults (55–65 years) completed the HDBR protocol.

Super‐Resolution of Planetary Images Based on Generative Adversarial Network

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 4, August 2026.
Abstract Currently, satellite imagery serves as the primary means of observing terrestrial planets such as the Mars, the Moon, and Mercury. Enhancing the resolution and quality of these images can provide more detailed insights into planetary surfaces. However, improvements in image quality are often limited by the constraints of sensor technology and ...

Alteration of a Mantle‐Derived Dunite Boulder in Jezero Crater, Mars

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract In 2023, the Mars 2020 Perseverance rover explored the youngest preserved deposits on the Western fan of Jezero crater, Mars: a field of meter‐scale boulders dispersed above the previously explored sandstone and siltstone units. Reflectance spectra of the boulders delineated two classes, one olivine‐bearing and one pyroxene‐bearing.

Symptom Overlap and Neurobiological Similarities Between Posttraumatic Stress Disorder and Tinnitus

Human Brain Mapping, Volume 47, Issue 10, July 2026.
Results from this study showed patterns in which those with PTSD and tinnitus demonstrated decreased functional connectivity between certain brain regions compared to those with only tinnitus and healthy controls. ABSTRACT Many symptoms of posttraumatic stress disorder (PTSD) overlap with the psychological sequelae of tinnitus, including sleep ...
