Many surfaces found on the Moon, asteroids, Mars, moons, and other planetary bodies are covered in a fine granular material known as regolith. Increased knowledge of the physical properties of extraterrestrial regolith surfaces will help advance the scientific knowledge of these bodies as well as the development of exploration (e.g., instrument and robotic) and in situ resource utilization (ISRU) systems. The Center for Space Resources at the Colorado School of Mines as part of the Institute for Modeling Plasma, Atmospheres, and Cosmic Dust of NASA's Solar System Exploration Research Virtual Institute has developed a novel system, called the ISRU Experimental Probe (IEP) that can support studies of dry and icy regolith from -196 to 150 °C and pressure from laboratory ambient pressure to 10 Torr. The IEP system and proof-of-concept results are presented in this paper.
在月球、小行星、火星、卫星及其他行星体上发现的许多表面都覆盖着一种名为“风化层”的细颗粒物质。增进对地球外风化层表面物理特性的了解，将有助于推进对这些天体的科学认识，以及促进探索（如仪器和机器人）和原位资源利用（ISRU）系统的发展。作为美国国家航空航天局太阳系探索研究虚拟研究所的等离子体、大气和宇宙尘埃建模研究所的一部分，科罗拉多矿业学院的空间资源中心开发了一种名为原位资源利用实验探测器（IEP）的新型系统，该系统能够支持在-196至150°C以及从实验室环境压力到10托的压力条件下对干燥和含冰风化层的研究。本文介绍了IEP系统及概念验证结果。
