On the Possible Origin of the Lunar Maria [PDF]

open access: yesNature, 1966
RECENT close-up photographs of the lunar surface on the western shores of Oceanus Procellarum, televized back to Earth by the Russian soft-lander Luna 9 on February 4, revealed for the first time the detailed micro-structure of typical mare ground down to a cm–mm scale.

Distribution characteristics of hydrogen elements on lunar surface based on CE2-GRS data

open access: yesHe jishu, 2023
BackgroundWater is the primary resource required for the exploitation of lunar resources. Investigating the distribution of water on the surface of the moon has become a focal point in the lunar exploration plans of several nations.PurposeThis study aims

Recent Tectonic Deformation of the Lunar Farside Mare and South Pole–Aitken Basin

open access: yesThe Planetary Science Journal
The timing and scale of lunar tectonism provide a crucial insight into the geologic evolution of Earth’s Moon. Within the nearside lunar maria, wrinkle ridges formed during and after the emplacement of the mare basalts as a result of subsidence-induced ...

Chronology of the Basalt Units Surrounding Chang’e-4 Landing Area

open access: yesRemote Sensing, 2021
The Chang’e-4 (CE-4) lunar probe, the first soft landing spacecraft on the far side of the Moon, successfully landed in the Von Kármán crater on 3 January 2019. Geological studies of the landing area have been conducted and more intensive studies will be

Morphological and morphometric aspects of the equine aortic valve: New insights for comparative studies in mammals

open access: yesThe Anatomical Record, EarlyView.
Abstract New data on the equine aortic valve obtained using advanced techniques is especially important given the greater availability of animal models for translational research. Here we characterized the morphological and morphometric aspects of the equine aortic valve from 60 healthy hearts collected at equine abattoirs.

Horizons and opportunities in lunar sample science [PDF]

open access: yes, 1985
The lunar sample research program was especially productive, but by no means have all the important answers been determined; continued study of lunar samples will further illuminate the shadows of our knowledge about the solar system.by Lunar and ...

Diverse Geological Evolution of Impact Basins on the Moon

open access: yesRemote Sensing, 2022
Impact basins are the dominant landforms on the lunar surface, and their geological evolution varies. This research studied the diversity in the geological evolution of three impact basins: the Dirichlet–Jackson Basin, the Nectaris Basin, and the ...

Morpho‐functional analyses of the jaw apparatus in the Blue‐and‐yellow Macaw (Ara ararauna, Psittaciformes, Aves): Adaptations to feeding behavior

open access: yesThe Anatomical Record, EarlyView.
Abstract Macaws are renowned for processing dry, mechanically resistant fruits, yet the species‐level anatomical and functional correlates of this performance remain incompletely resolved. We examined the feeding apparatus of the Blue‐and‐yellow Macaw (Ara ararauna) using an integrated approach that combines osteology, myology, and bite‐force estimates

Interactions between complex craters and the lunar crust: Analysis using GRAIL data

open access: yes, 2016
A high-resolution gravity map over the entire lunar surface has been derived from data acquired by the Gravity Recovery and Interior Laboratory (GRAIL) mission. Soderblom et al.

Lunar Boulder Fields as Indicators of Recent Tectonic Activity

open access: yesThe Planetary Science Journal
Wrinkle ridges are the predominant tectonic structure on the nearside lunar maria. Although lunar wrinkle ridge formation began as early as ∼3.9–4.0 Ga, recent investigations have identified wrinkle ridges in the lunar maria that were tectonically active
