Abstract

The exploration and conquest of extra-terrestrial bodies in the Solar System (e.g. the Moon and Mars) is very likely in a near future. Therefore, the construction of lunar and mars based structures is increasingly discussed by the scientific community worldwide.  Various concepts have been proposed for lunar and mars structures. For instance, 3D printing of building components from lunar regolith, use of natural caves for the construction of lunar bases, or inflatable pressurized tensile structures using fiber composites for human-friendly habitats. A fast, accurate and remote measuring technique is needed for these types of construction tasks. The terrestrial laser scanning technique (TLS) may be used for such project. To check the suitability of TLS techniques to be used on the Moon or Mars, initial measurements must be conducted on Earth. Unfortunately, extra-terrestrial soils are not available for general research for example to test a large scale structures. The only feasible solution is to use comparable materials e.g. artificial lunar and mars soil materials to practice exploration strategies. Multiple lunar soil simulants (LSSs) and mars soil simulants (MSSs), have been already developed. In this investigation, simulants developed by Zarzycki and Katzer 2019 were used.  The main aim of this research is radiometric analysis of TLS point clouds from the measurement of lunar and mars soil simulants. The detailed research focuses on the analysis of laser beam dispersion and absorption in soil simulants. It should be noted that, the dispersion and absorption of the laser beam for the scanned surface is a key factor in TLS remote measurements. The potential of TLSs in this investigation were tested using the time-of-flight scanner Leica ScanStation C10 and phase-shift scanner Z+F IMAGER 5016. The test results were also collated and compared.
