Mr Karlis Slumba

Higher Degree by Research Candidate

School of Civil Engineering and Construction

College of Engineering and Information Technology


With background in Physics, Planetary Science, Geotech, and Geophysics, my research interests are in payloads for planetary science missions, exploration, space resources, and off-Earth construction. 

At the Adelaide University, I am working on combining dynamic cone penetration (DCP) and seismic methods for lunar applications. At the Exterres lab we have a large regolith pit with LHS-1E regolith simulant where I have been doing experiments with various geotechnical and geophysical instruments. I have found that DCP works perfectly as a seismic source. Similar geotechnical tests have been performed in the Regolith thermal vacuum chamber at the Exterres lab. 

Have been working on development and testing of extra-terrestrial regolith simulants (Moon, Mars, asteroids, icy bodies, lunar polar icy simulants, for ISRU, for gravity offloaded testing, for vacuum testing) at several institutions (University of Central Florida, Exolith lab, University of Grenoble, Adelaide University, Korea Institute for Geoscience and Mineral resources (KIGAM)).
