چکیده
To satisfy the essential needs, including energy requirements, for human and robotic space explorations on planetary objects like Moon, Mars asteroids, proper exploitation of resources available in-situ represents a crucial issue. Along this line, present work investigates potential sintered lunar regolith simulant (JSC-1A) possible solar harvesting thermal storage applications. Regolith powders are first consolidated by Spark Plasma Sintering (SPS) at 700 900 °C to produce bulk samples with different relative densities, i.e. 86 98%, respectively, surface porosities. Negligible changes from compositional point view induced SPS °C, whereas decrease original glassy phase content is observed when operating °C. The optical properties pristine compared, considering spectral absorptance/emittance, integrated absorptance emittance estimated in temperature range representative ISRU application, 100 1300 K. We found that sintering process-dependent way, an increased shown pellets respect powders. • Bulks produced using Sintering. Samples 86% 98% density obtained temperatures. Composition, microstructural assessed, comparing native applications discussed. sample best absorber temperatures lower than 1000 option buried sensible-heat TES material. Native can provide insulation TES.

متن کاملScientific and Resource Characterization of Lunar Regolith Using Dielectric
Introduction: Water ice and ilmenite both have unique dielectric responses that can be used to detect their concentration as a function of depth, noninvasively from the lunar surface. Electrical measurements at the surface can also be used to determine the density of the lunar regolith. Subsurface water ice may exist in permanently shadowed regions near the poles of the Moon [1-6]. The presence...

In the present study, nearly fully dense monolithic ZrC samples are produced and broadly characterized from microstructural, mechanical and optical points of view. Specifically, 98% dense products are obtained by Spark Plasma Sintering (SPS) after 20 min dwell time at 1850 °C starting from powders preliminarily prepared by Self-propagating High-temperature Synthesis (SHS) followed by 20 min bal...
