Turkish Lunar Regolith Simulant TBG-1

Earth and Space 2022, 2023
Being terrestrial for so many thousands of years, humanity is now advancing in the direction of being extraterrestrial. Attempts made until now were quite promising, like walking on the Moon, living in stations for very long durations miles away from Earth, sending probes to unimaginable distances in space and bringing them back to Earth, etc.

Evaluations of lunar regolith simulants

Planetary and Space Science, 2016
Apollo lunar regolith samples are not available in quantity for engineering studies with In-Situ Resource Utilization (ISRU). Therefore, with expectation of a return to the Moon, dozens of regolith (soil) simulants have been developed, to some extent a result of inefficient distribution of NASA-sanctioned simulants.

Developing an Anorthositic Lunar Regolith Simulant

57th International Astronautical Congress, 2006
We must increase our understanding of the regolith, as future human missions to both the Moon and Mars will rely on it for insitu resource utilization (ISRU) to produce fuel, water, and other life support and construction materials. ISRU will be more cost effective than shipping required materials from Earth.

Thermal properties of lunar regolith simulant melting specimen

Acta Astronautica, 2021
Abstract In this paper, investigations of two types of lunar regolith simulants, called TUBS-M and TUBS-T, developed by the Institute of Space Systems (IRAS) at TU Braunschweig are presented. These investigations are focused on the thermal properties, namely the specific heat capacity and the thermal conductivity.

Robotic drilling tests in simulated lunar regolith environment

Journal of Field Robotics, 2021
AbstractA deep extraterrestrial drilling mission potentially adds a new level of complexity, and it is crucial to understand the associated challenges. To cope with China's Chang'E 5 mission to return subsurface regolith samples from the Moon, a series of laboratory tests were performed to validate the lunar robotic drilling from 2015 to 2018.

Viscosity measurements of selected lunar regolith simulants

American Mineralogist
Abstract In the context of evaluating lunar construction options, this study focuses on characterizing the viscosities and glass transition properties of lunar regolith simulants to support the development of additive manufacturing processes using molten regolith. Employing the modular TUBS lunar regolith simulant system, we measured the

Recovery rate prediction in lunar regolith simulant drilling

Acta Astronautica, 2017
Abstract Drilling and coring, as an effective way to acquire lunar regolith along the depth, is widely used in the field of planetary explorations. Because there is no relative sliding between the lunar regolith and the flexible tube, using the flexible tube coring method can acquire high recovery rate and keep the stratification of regolith samples.

Strength Properties of JSC-1A Lunar Regolith Simulant

Journal of Geotechnical and Geoenvironmental Engineering, 2009
The paper presents a description of physical properties and a characterization of shear strength behavior of JSC-1A lunar regolith simulant. Specific gravity of solids, particle size analysis, and minimum and maximum index densities were measured according to ASTM standards.

Drilling Results in Ice-Bound Simulated Lunar Regolith

AIP Conference Proceedings, 2007
Reaching the cold traps at the lunar poles and directly sensing the subsurface regolith is a primary goal of lunar exploration, especially as a means of prospecting for future In Situ Resource Utilization (ISRU) efforts. The Construction and Resource Utilization Explorer project (CRUX) addressed technology development associated with a modular ...
