“…According to NASA's data, lunar regolith is mainly composed of silicon (45.4%) but also bears a considerable amount of calcium (11.8%) (Taylor, 1975). Notably, a study also analyzed the distribution of plagioclase (a calcium-rich feldspar) on the Moon, and showed a high abundance of this material (Ohtake et al, 2009;Baasch et al, 2021). Moon mining approaches, combined with the fabrication of LBMs and 3D printing technologies, could provide a low cost-solution for building infrastructure on Earth's Moon and other planets (Cesaretti et al, 2014;Vítek et al, 2020).…”

Subterranean environments on Earth serve as an analog for the study of microbes on other planets, which has become an active area of research. Although it might sound contradictory that photosynthetic cyanobacteria thrive in extreme low light environments, they are frequent inhabitants of caves on Earth. Throughout the phylum these cyanobacteria have developed unique adaptations that cannot only be used for biotechnological processes but also have implications for astrobiology. They can, for example, both accommodate for the low light conditions by producing specific pigments that allow photosynthesis in near-infrared (IR) radiation/far-red light, and they can synthesize bioplastic compounds and calcium carbonate sheaths which represent valuable resources during human colonization of other planets or rock bodies. This article will highlight the potential benefits of cave-inhabiting cyanobacteria and will present a suitable bioreactor technique for the utilization of these special microbes during future space missions.

“…The various types of aluminium may be divided into two general classes (a) casting alloys (those suitable for casting e.g. in regolith [74]) and (b) wrought alloys (those which may be shaped by rolling, drawing, or forging) and rather brought from planet earth (c.f. chapter 1.4).…”

In recent years, space agencies like NASA and ESA have expanded their research activities in the field of Manufacturing in Space. These measures serve to reduce limitations and costs through fairing size, launch mass capabilities or logistic missions. The objective, in turn, is to develop technologies and processes that enable on-demand manufacturing for long-term space missions and on other celestial bodies. Within these research activities, in-situ resources utilization (ISRU) and recycling are major topics. Consequently, this paper considers what is required on-demand in future space missions and provides a corresponding overview of the in-space manufacturing state of the art. The latter is significantly influenced by research activities in the field of additive manufacturing, with only a few results available in the field of subtractive processing. In conclusion, a novel approach for in-situ resource utilization based subtractive manufacturing in space is presented to supplement the existing processes. The approach presented is based on a water abrasive jet process, with regolith simulate being used as the abrasive to separate metal and glass.

Penelitian ini bertujuan mengetahui pengaruh temperatur tuang pada pengecoran daur ulang Al-Si terhadap struktur mikro dan kekerasan dengan menggunakan pola Styrofoam. Material aluminium dari velg bekas diplih sebagai bahan utama dalam penelitian ini. Parameter yang digunakan dalam pengecoran adalah temperatur tuang dengan variasi 660, 710, dan 760oC. Pengamatan struktur mikro dan pengukuran SDAS menggunakan mikroskop optic dan image analysis software. Pengujian kekerasan dilakukan untuk mengetahui sifat mekanis material. Hasil pengujian menunjukkan SDAS semakin kasar atau meningkat 56 % pada temperatur tuang 760o C sehingga mengalami peningkatan kekuatan mekanik sebesar 2.59%.
