Investigation of the melting behavior of laser-melted lunar regolith simulant for in-situ construction

Journal of Materials Research and Technology
Additive manufacturing of lunar regolith is one of the most promising methods for lunar surface construction. In order to obtain excellent formability of lunar regolith, the interaction between laser and lunar regolith has to be studied in detail.

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 ...

Lunar Surface Gravimeter Experiment [PDF]

The lunar surface gravimeter which was emplaced on the moon by the Apollo 17 flight is described and a schematic diagram of the sensor is provided. The objective of the lunar surface gravimeter is to use the moon as an instrumented antenna to detect ...

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.

Shape-from-shading Refinement of LOLA and LROC NAC Digital Elevation Models: Applications to Upcoming Human and Robotic Exploration of the Moon

The Planetary Science Journal
The Lunar Reconnaissance Orbiter (LRO) has returned a wealth of remotely sensed data of the Moon over the past 15 years. As preparations are under way to return humans to the lunar surface with the Artemis campaign, LRO data have become a cornerstone for

Accurate Mapping and Evaluation of Small Impact Craters within the Lunar Landing Area

Remote Sensing
Impact craters, as the most distinct lunar structural unit and geological structure, are marked on the Moon’s surface. For over a decade, researchers have focused on identifying and exploring large- to medium-sized impact craters on the surface of the ...

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 ...

Shadow-constrained shape-from-shading for pixel-wise 3D surface reconstruction at the lunar south pole

Geo-spatial Information Science
High-resolution digital elevation models (DEMs) of the lunar surface are crucial for lunar exploration missions and scientific research. The emergence of advanced technologies, such as Shape-from-Shading (SfS), has enabled the generation of pixel-wise ...
