Survivability of Amino Acids in Lunar Soil

open access: yesThe Planetary Science Journal
We present a laboratory investigation on the survivability of amino acids in lunar simulant soil under conditions similar to the lunar surface. Survival rates of various amino acids are quantified using ultra-high-performance liquid chromatography in ...

Evaluation of lunar soil sampling disturbance based on penetration resistance method

open access: yesFrontiers in Astronomy and Space Sciences
IntroductionTo investigate the impact of surface sampling operations on the physical and mechanical properties of lunar soil—defined as the granular, sub-centimeter-sized fraction of the lunar regolith—and to mitigate design errors in sampling missions ...

Development and mechanical properties of construction materials from lunar simulants [PDF]

open access: yes
The development of construction materials such as concrete from lunar soils without the use of water requires a different methodology than that used for conventional terrestrial concrete. Currently, this research involves two aspects: (1) liquefaction of

An investigation of the thermal shock resistance of lunar regolith and the recovery of hydrogen from lunar soil heated using microwave radiation [PDF]

open access: yes
The objective is to develop a better understanding of the thermal shock properties of lunar regolith sintered using 2.45 GHz electromagnetic radiation and to do a preliminary study into the recovery of bound hydrogen in lunar soil heated using 2.45 GHz ...

Shock-treated Lunar Soil Simulant: Preliminary Assessment as a Construction Material [PDF]

open access: yes
In an effort to examine the feasibility of applying dynamic compaction techniques to fabricate construction materials from lunar regolith, preliminary explosive shock-loading experiments on lunar soil simulants were carried out.

ISRU Soil Mechanics Vacuum Facility: Soil Bin Preparation and Simulant Strength Characterization [PDF]

open access: yes, 2012
Testing in relevant environments is key to exploration mission hardware development. This is true on both the component level (in early development) and system level (in late development stages).

Mechanical behaviour of additively manufactured lunar regolith simulant components [PDF]

open access: yes, 2018
Additive manufacturing and its related techniques have frequently been put forward as a promising candidate for planetary in-situ manufacturing, from building life-sustaining habitats on the Moon to fabricating various replacements parts, aiming to ...
