Abstract: A major challenge to making celestial soil mechanics viable is to re-engineer the profession's toolkit to provide geotechnical solutions without the luxury of ex-situ and in-situ testing as we know them on Earth. It's essential to develop an understanding of fundamental mechanical, thermal, and fluidization properties of granular media on other celestial bodies. Regoliths, dusts, and other discrete loose superficial materials have — and will be — the most abundant material humanity interacts with on non-Earth explorations.
