Recently, the goal of space exploration has shifted from the incognito of the solar system to the Moon. Concepts like human permanence on the Moon and thermal protective structures made with ISRU (in situ resource utilization) of raw materials have started to be implemented. By limiting the need to launch supplies from the Earth, the paradigm of spaceflight is changed, privileging the vanguard of the utilisation of resources in situ. Still, the main challenges of surviving the radiation dose and the cryogenic temperatures of the lunar night remain. Recent studies have demonstrated how innovative composite materials can help reduce the temperature stress on exploration vehicles. This research presents the material properties of aerogel insulating materials combined with LHS (lunar highlands simulant) regolith obtained by freeze frying. Organic-based aerogels with different percentages of LHS have been analysed in terms of material, morphology, and thermal properties.
最近，太空探索的目标已从探索太阳系的未知领域转向月球。诸如人类在月球上长期居住以及利用原位资源利用（ISRU）原材料制造的热防护结构等概念已开始付诸实践。通过减少从地球发射物资的需求，航天飞行模式发生了改变，优先考虑原位资源利用的前沿技术。尽管如此，在月球夜间的辐射剂量和低温环境中生存的主要挑战依然存在。最近的研究表明，创新的复合材料如何有助于减轻探索飞行器上的温度应力。本研究展示了通过冷冻干燥获得的气凝胶隔热材料与月球高地模拟物（LHS）风化层相结合的材料特性。对含有不同比例LHS的有机基气凝胶进行了材料、形态和热性能方面的分析。
