The Potential for Lunar and Martian Regolith Simulants to Sustain Plant Growth: A Multidisciplinary Overview

Frontiers in Astronomy and Space Sciences, 2022
Bioregenerative life support systems (BLSS) are conceived of and developed so as to provide food sources for crewed missions to the Moon or Mars. The in situ resource utilization (ISRU) approach aims to reduce terrestrial input into a BLSS by using ...

In Situ Methanation on Mars: A Process Concept Study on the Impact of H2/CO2 and Recycle Ratio

Chemie Ingenieur Technik, Volume 98, Issue 4, Page 156-164, April 2026.
The rocket propellant methane can be produced on Mars by in situ resource utilization. The H2/CO2 ratio is decisive, and excess H2 is favored for providing sufficient propellant purity. The operation mode—with or without recycling of unreacted reactants—depends on the resource availability of the selected landing site. Abstract For return missions from

Bio‐Inspired Swarm Robotics Design for Mine Automation

Natural Sciences, Volume 6, Issue 2, April 2026.
Ants demonstrate tandem running for cooperative haulage, and honeybees use memory‐based routes between hive and flowers. These behaviours inspire autonomous haulage robots in open‐pit mines to achieve efficient scan‐plan‐retrieve ore transport, replacing small haulage robots with large mining trucks.

Synthesis of Peptides, Peptide Nucleic Acid Components, and Other Biogenic Compounds From a Three‐Component Prebiotic Mixture

Chemistry – A European Journal, Volume 32, Issue 9, 2 March 2026.
High‐energy proton irradiation of a formamide–diaminomaleonitrile–glycine system in the presence of meteorites produces a broad spectrum of biogenic compounds, including nucleobases, nucleosides, peptides, and nucleobase–peptide conjugates, highlighting a chemically plausible prebiotic network.

Nuclear Power from Lunar ISRU [PDF]

Insights in Mining Science & Technology, 2019
Thorium on the lunar surface can be transmuted into fissile uranium suitable for a controlled chain reaction to provide heat. Thorium is fertile, requiring bombardment by neutrons to become a suitable nuclear fuel. Oxides of thorium are dense and can be concentrated and beneficiated from comminuted regolith via inertial or thermal means. A neutron flux

ISRU Implications for Lunar and Martian Plume Effects [PDF]

47th AIAA Aerospace Sciences Meeting including The New Horizons Forum and Aerospace Exposition, 2009
Experiments, analyses, and simulations have shown that the engine exhaust plume of a Mars lander large enough for human spaceflight will create a deep crater in the martian soil, blowing ejecta to approximately 1 km distance, damaging the bottom of the lander with high-momentum rock impacts, and possibly tilting the lander as the excavated hole ...

Crater Observing Bioinspired Rolling Articulator (COBRA)

Advanced Intelligent Systems, Volume 8, Issue 3, March 2026.
Crater Observing Bio‐inspired Rolling Articulator (COBRA) is a modular, snake‐inspired robot that addresses the mobility challenges of extraterrestrial exploration sites such as Shackleton Crater. Incorporating snake‐like gaits and tumbling locomotion, COBRA navigates both uneven surfaces and steep crater walls.

Diurnal Temperature Variability at Latitudinally Distinct Sites on the Moon

Earth and Space Science, Volume 13, Issue 3, March 2026.
Abstract The thermophysical environment of the Moon plays a crucial role for future exploration, resource utilization and also in understanding its geological evolution. While global‐scale surface temperature distributions have been reasonably well constrained through numerical modeling and orbiter observations, recent in situ measurements have ...

Revealing the Internal Structure of Mars‐Analog Glaciers From Drone‐Based Radar Sounding

Journal of Geophysical Research: Planets, Volume 131, Issue 3, March 2026.
Abstract Martian debris‐covered glaciers (DCGs) contain large quantities of water ice beneath a protective layer of rock and dust. Properties of the overlying regolith such as density and depth to ice are critical parameters for guiding in situ resource utilization (ISRU) of water and coring missions targeting potential habitats.
