The reactivity of experimentally reduced lunar regolith simulants: Health implications for future crewed missions to the lunar surface

open access: yesMeteoritics &Planetary Science, Volume 59, Issue 9, Page 2487-2504, September 2024.
Abstract Crewed missions to the Moon may resume as early as 2026 with NASA's Artemis III mission, and lunar dust exposure/inhalation is a potentially serious health hazard that requires detailed study. Current dust exposure limits are based on Apollo‐era samples that spent decades in long‐term storage on Earth; their diminished reactivity may lead to ...

Spirulina supported plant growth in regolith simulants and elevated levels of CO2

open access: yesFrontiers in Space Technologies
IntroductionA key element for sustainable off-world habitation is the ability to grow food through in-situ resource utilization (ISRU). Growth substrates are required to overcome the challenges of ISRU in the space environment, including the use of ...

Estimation of energy and material use of sintering-based construction for a lunar outpost - with the example of SinterHab module design [PDF]

open access: yes, 2015
In this paper, we would revisit the usability of microwave for lunar regolith sintering through an in-depth experiment, and examine the minimum materials and energy required for sintering based on the SinterHab design.

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 ...

Additive manufacturing of physical assets by using ceramic multicomponent extra-terrestrial materials [PDF]

open access: yes, 2016
Powder Bed Fusion (PBF) is a range of advanced manufacturing technologies that can fabricate three-dimensional assets directly from CAD data, on a successive layer-by-layer strategy by using thermal energy, typically from a laser source, to irradiate and

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 ...

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
