A New Global Perspective on Recent Tectonism in the Lunar Maria

The Planetary Science Journal
Earth’s Moon exhibits evidence that it is tectonically active. That evidence includes the Apollo Lunar Seismic Experiment detection of shallow moonquakes and the presence of geologically young tectonic features at the lunar surface. Lobate scarps are one

A Pathfinder Lunar Construction Mission Concept Using Regolith Filled Bags

Aerospace
Two challenges that have a permanent presence on the Moon are solar and cosmic radiation, as well as the large surface temperature variation between lunar day and night.

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

Experimental Physiology, EarlyView.
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 ...

High-Precision Disparity Estimation for Lunar Scene Using Optimized Census Transform and Superpixel Refinement

Remote Sensing
High-precision lunar scene 3D data are essential for lunar exploration and the construction of scientific research stations. Currently, most existing data from orbital imagery offers resolutions up to 0.5–2 m, which is inadequate for tasks requiring ...

The search for the cause of the low albedo of the moon [PDF]

Experimentation concerning lunar weathering and its effect on the albedo of the surface cover consisted of: (1) determination of the surface chemical composition of lunar soil and ground-up rock samples by Auger electron spectroscopy, (2) measurement of

Blood flow restriction: The acute effects of body tilting and reduced gravity analogues on limb occlusion pressure

Experimental Physiology, EarlyView.
Abstract Blood flow restriction (BFR) has been identified as a potential countermeasure to mitigate physiological deconditioning during spaceflight. Guidelines recommend that tourniquet pressure be prescribed relative to limb occlusion pressure (LOP); however, it is unclear whether body tilting or reduced gravity analogues influence LOP.

Enhanced magnetic field production during oblique hypervelocity impacts [PDF]

The natural remanent magnetization of the lunar surface as displayed in returned lunar samples and the data returned by the Apollo subsatellite magnetometer has an unexpectedly high magnitude and exhibits spatial variation at all scales.

Impact of a 12‐week high‐intensity interval training intervention on cardiac structure and function after COVID‐19 at 12‐month follow‐up

Experimental Physiology, EarlyView.
Abstract In patients previously hospitalised for COVID‐19, a 12‐week high‐intensity interval training (HIIT) intervention has previously been shown to increase left ventricular mass (LVM) immediately after the intervention. In the present study, we examined the effects of the same HIIT scheme on LVM, pulmonary diffusing capacity, symptom severity and ...

Modeling the Effects of Anthropogenic Activities on the Lunar Environment with a Systems-theoretic Approach

The Planetary Science Journal
An increasing number of missions to the Moon are planned for the future. However, their long-term, cumulative impacts on the lunar environment are unknown. Research indicates that some important scientific discovery potential may be permanently lost, and
