Development of a Hydrogeological Conceptual Model for Shallow Aquifers in the Data Scarce Upper Blue Nile Basin

open access: yesHydrology, 2019
Rural communities in sub-Saharan Africa commonly rely on shallow hand-dug wells and springs; consequently, shallow aquifers are an extremely important water source.

Mass wasting triggered by seasonal CO2 sublimation under Martian atmospheric conditions: Laboratory experiments [PDF]

open access: yes, 2016
Sublimation is a recognized process by which planetary landscapes can be modified. However, interpretation of whether sublimation is involved in downslope movements on Mars and other bodies is restricted by a lack of empirical data to constrain this ...

Stance and Gait Analysis of Apollo Astronauts on the Moon

open access: yesMuscle &Nerve, EarlyView.
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.

Morphological and Spectral Characterization of Lunar Regolith Breakdown due to Water Ice

open access: yesThe Planetary Science Journal
Remote sensing observations of the Moon suggest that the lunar polar regolith environment is affected by several natural processes that may cause the regolith in these regions to become more porous and fine particulate.

Scaling forces to asteroid surfaces: The role of cohesion

open access: yes, 2010
The scaling of physical forces to the extremely low ambient gravitational acceleration regimes found on the surfaces of small asteroids is performed. Resulting from this, it is found that van der Waals cohesive forces between regolith grains on asteroid ...
