A new-type wheel-legged lunar rover and its mobile performance analysis

open access: yes, 2009
Based on the principle of a double-half-revolution mechanism, a new-style wheel-legged lunar rover was proposed in this paper. Its mobile system includes rover body frame, four identical wheel-legged components and steering brackets, etc.

Moonlight Duration and Intensity Favour Nocturnal Activity in a Diurnal Desert Bird

open access: yesEthology, Volume 132, Issue 9, Page 629-641, September 2026.
Accelerometer data show that Canarian houbara bustards increase nocturnal activity two‐ to fivefold when the moon is visible, with activity rising as moonlit duration and illumination increase. Both display and non‐display behaviours peaked around full moon, reaching up to half of peak daytime levels, with males increasing visual displays during ...

Organized after‐school activities and Asian American high school students' Asian American identity and Asian American racial identity ideological values

open access: yesJournal of Research on Adolescence, Volume 36, Issue 3, September 2026.
Abstract The present study qualitatively examined how Asian American college students thought their participation in organized after‐school activities during high school was related to their Asian American identity and Asian American racial identity ideological values.

Development and characterization of a regional lunar soil simulant for emirates lunar missions

open access: yesInternational Journal of Mining Science and Technology
Lunar soil simulants (LSS) have been pivotal in the success of past and current lunar missions. They have enhanced the design of lander and rover wheels through interaction studies on the lunar testbed under simulated environmental conditions.

Confined spaces in space: Cerebral implications of chronic elevations of inspired carbon dioxide and implications for long‐duration space travel

open access: yesExperimental Physiology, Volume 111, Issue 9, Page 3968-3982, 1 September 2026.
Abstract Cerebrovascular regulation is critically dependent upon the arterial partial pressure of carbon dioxide (PaCO2${P_{{\mathrm{aC}}{{\mathrm{O}}_{\mathrm{2}}}}}$), owing to its effect on cerebral blood flow, tissue PCO2${P_{{\mathrm{C}}{{\mathrm{O}}_{\mathrm{2}}}}}$, tissue proton concentration, cerebral metabolism and cognitive and neuronal ...

Visual Odometry for Planetary Exploration Rovers in Sandy Terrains

open access: yesInternational Journal of Advanced Robotic Systems, 2013
Visual odometry provides planetary exploration rovers with accurate knowledge of their position and orientation, which needs effective feature tracking results, especially in barren sandy terrains.

Jumping on the moon as a potential exercise countermeasure

open access: yesExperimental Physiology, Volume 111, Issue 9, Page 4073-4088, 1 September 2026.
Abstract The Moon's gravitational field strength (17% Earth's gravity) may facilitate the use of bodyweight jumping as an exercise countermeasure against musculoskeletal and cardiovascular deconditioning in reduced gravity settings. The present study characterised the acute physiological and kinetic responses to bodyweight jumping in simulated Lunar ...

Comprehensive mapping of lunar surface chemistry by adding Chang'e-5 samples with deep learning

open access: yesNature Communications, 2023
Lunar surface chemistry is essential for revealing petrological characteristics to understand the evolution of the Moon. Existing chemistry mapping from Apollo and Luna returned samples could only calibrate chemical features before 3.0 Gyr, missing the ...

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

open access: yesExperimental Physiology, Volume 111, Issue 9, Page 4015-4040, 1 September 2026.
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 ...
