“…To characterize abrasive wear resistance of lunar drilling devices, homogeneous simulated lunar regolith particles without agglomeration (Figure 1a) were chosen as the abrasive medium. The particle size of the original lunar soil was micro-/nano-sized [4,5,21,22,23]; therefore, the distribution of simulated lunar regolith particles also showed a Gaussian distribution centered around 80 μm (Figure 1b). According to the characteristics of lunar mare basalts, simulated lunar regolith particles composed of SiO 2 , Al 2 O 3 , CaO, TiO 2 , FeO and MgO were made from volcanic rock [22,23].…”

“…For lunar exploration, micro-/nano-scaled lunar regolith particles that cover the surface of the moon always cause serious abrasive wear of a lunar rover [1,2,3,4,5]. A great number of lunar rover parts, such as the drill pipe and sleeve used on the lunar drilling, are made of titanium (Ti) and its alloys due to its low density, high strength, excellent corrosion resistance, etc.…”

Nevertheless, the poor abrasion wear resistance of Ti and its alloys restricts the service life and operating limit of drill devices [8,10].…”

The objective of the given work was to investigate abrasive wear behaviours of titanium (Ti) treated by ultrasonic surface rolling processing (USRP) pre-treatment and plasma nitriding (PN). Simulated lunar regolith particles (SLRPs) were employed as abrasive materials during characterization of tribological performances. The experimental results showed that SLRPs cause severe abrasive wear on Ti plasma-nitrided at 750 °C via the mechanism of micro-cutting. Due to the formation of a harder and thicker nitriding layer, the abrasive wear resistance of the Ti plasma-nitrided at 850 °C was enhanced, and its wear mechanism was mainly fatigue. USRP pre-treatment was effective at enhancing the abrasive wear resistance of plasma-nitrided Ti, due to the enhancement of the hardness and thickness of the nitride layer. Nevertheless, SLRPs significantly decreased the friction coefficient of Ti treated by USRP pre-treatment and PN, because the rolling of small granular abrasives impeded the adhesion of the worn surface. Furthermore, USRP pre-treatment also caused the formation of a dimpled surface with a large number of micropores which can hold wear debris during tribo-tests, and finally, polishing and rolling the wear debris resulted in a low friction coefficient (about 0.5).

“…In this context, the use of space resources is one of the key directions in preparation for future human missions to the Moon. The so-called in situ Resource Utilization (ISRU) program by ESA and NASA explores the possibility of converting local resources of space bodies into valuable products and materials [5][6][7][8]. ISRU will ensure the sustainability and energy efficiency of space exploration, reduce the cost of delivery from Earth, and minimize mission risks.…”

Understanding the effect of radiation on materials is fundamental for space exploration. Energetic charged particles impacting materials create electronic excitations, atomic displacements, and nuclear fragmentation. Monte Carlo particle transport simulations are the most common approach for modeling radiation damage in materials. However, radiation damage is a multiscale problem, both in time and in length, an aspect treated by the Monte Carlo simulations only to a limited extent. In this chapter, after introducing the Monte Carlo particle transport method, we present a multiscale approach to study different stages of radiation damage which allows for the synergy between the electronic and nuclear effects induced in materials. We focus on cumulative displacement effects induced by radiation below the regime of hadronic interactions. We then discuss selected studies of radiation damage in materials of importance and potential use for the exploration and settlement on the Moon, ranging from semiconductors to alloys and from polymers to the natural regolith. Additionally, we overview some of the novel materials with outstanding properties, such as low weight, increased radiation resistance, and self-healing capabilities with a potential to reduce mission costs and improve prospects for extended human exploration of extraterrestrial bodies.

“…Despite these improvements, future human missions to the lunar surface will still be constrained by mass transportation logistics [8] [9]. This is likely to be especially true if mining equipment has to be flown [10] [11] to the lunar surface for, for example, mining water, aluminium, titanium, iron or oxygen [12] .…”

International space agencies are aiming to establish permanent outposts on the lunar surface. For that purpose, new technologies and equipment are being developed which will enable and augment these mission goals. To increase the duration of a long-term planetary mission and to expand mission capabilities, the ability to manufacture transparent glass in-situ could be an important enabler on the lunar surface. Results presented in this work show that it is feasible to use different lunar regolith simulants to manufacture optically transparent glass by magnetically beneficiating regolith prior to processing. Beneficiated regolith simulant was melted, cast into glass nuggets which were then ground, lapped and polished into glass slides of 1mm thickness. The glass slides' surface roughness and geometry were measured, prior to optical analysis, which showed an average transmission of about 80 % of light in the wavelength range from 250 to 1250 nm. A comparable reference glass sample performed only about 9 % (absolute) better on average. From these results it seems viable to manufacture transparent glass from actual lunar regolith on the lunar surface as well, however, differences in regolith simulant and actual regolith still need to be fully explored -Regolith may be available on the lunar surface in unlimited quantities and therefore open up new strategic possibilities.
