Abstract

In-Situ Resource Utilization (ISRU) approaches hold significant importance in plans for space colonization. This work explores a different ISRU concept applying fast-firing, a robust and well-known industrial process, to Mars regolith simulant (MGS-1). The fast-fired specimens were compared to the ones obtained by conventional sintered under low heating rates. When the holding time at the firing temperature is longer than 15 min, fast-fired specimens exhibited higher density and flexural strength (> 35 MPa) than conventional sintering. For both processes, the bulk density values and the mechanical properties of the regolith compacts were enhanced with increasing dwell time. This was attributed to higher heating rates changing the densification/crystallization kinetics involving the basalt glass in the regolith composition. Specifically, high heating rate promotes sintering over crystallization. On these bases, fast firing can be considered a potential candidate for ISRU on Mars.

火星风化层模拟物的快速发射技术：推进ISRU能力

就地资源利用（ISRU）方法在空间殖民计划中具有重要意义。这项工作探索了一种不同的ISRU概念，将快速燃烧，一个强大且众所周知的工业过程应用于火星风化模拟（MGS-1）。将快速烧结试样与低升温速率常规烧结试样进行了比较。当烧成温度下保温时间大于15 min时，快烧试样具有更高的密度和抗弯强度(>；35 MPa)比常规烧结。在这两种工艺中，随着停留时间的增加，压实土的容重值和力学性能都有所提高。这是由于较高的加热速率改变了风化层成分中玄武岩玻璃的致密/结晶动力学。具体来说，高加热速率促进烧结而不是结晶。在这些基地上，快速发射可以被认为是火星上ISRU的潜在候选者。

期刊介绍： Icarus is devoted to the publication of original contributions in the field of Solar System studies. Manuscripts reporting the results of new research - observational, experimental, or theoretical - concerning the astronomy, geology, meteorology, physics, chemistry, biology, and other scientific aspects of our Solar System or extrasolar systems are welcome. The journal generally does not publish papers devoted exclusively to the Sun, the Earth, celestial mechanics, meteoritics, or astrophysics. Icarus does not publish papers that provide "improved" versions of Bode''s law, or other numerical relations, without a sound physical basis. Icarus does not publish meeting announcements or general notices. Reviews, historical papers, and manuscripts describing spacecraft instrumentation may be considered, but only with prior approval of the editor. An entire issue of the journal is occasionally devoted to a single subject, usually arising from a conference on the same topic. The language of publication is English. American or British usage is accepted, but not a mixture of these.
