Long-term degradation of optical devices on the moon

, 2010
Forty years ago, Apollo astronauts placed the first of several retroreflector arrays on the lunar surface. Their continued usefulness for laser-ranging might suggest that the lunar environment does not damage optical devices.

The micrometeoroid complex and evolution of the lunar regolith [PDF]

The interaction of the micrometeoroid complex with the lunar surface is evidenced by numerous glass-lined microcraters on virtually every lunar surface exposed to space.

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.

Stance and Gait Analysis of Apollo Astronauts on the Moon. [PDF]

Muscle Nerve
ABSTRACT Introduction/Aim As humans return to the Moon, safe efficient ambulation and fall prevention on the lunar surface are key concerns. The analysis of gait from archived Apollo mission video footage is now possible with pose estimation video analysis software.

Blood flow restriction exercise during microgravity exposure in parabolic flight

Experimental Physiology, EarlyView.
Abstract This case report evaluates whether it is possible to perform blood flow restriction (BFR) exercise during exposure to microgravity. The objectives were three‐fold: (1) to determine if a personalised tourniquet system (PTS) hardware technology performs nominally and enables BFR exercise in microgravity; (2) to determine if BFR augments the ...

Sex differences in cerebral blood flow and cardiac function in response to exercise in the heat

Experimental Physiology, EarlyView.
Abstract We investigated the effect of exercising in hot conditions on cerebral blood flow and systolic left ventricular (LV) function in males and females, to explore sex differences. The experimental condition consisted of walking on a treadmill at 5 km/h and 2% incline, inside a heat chamber at 40°C (50% relative humidity), for 90 min.

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
