Space colonisation has rapidly moved several steps closer to becoming a reality due to significant advances in rocket propulsion and design, astronautics and astrophysics, robotics and medicine. However, the exploration and utilisation of space pose many challenges, including technical, economic, legal and ethical issues. These challenges will require an interdisciplinary approach involving engaged researchers in each of these fields to understand how space can best be used for the benefit of both current and future generations. Determining the structure and geomechanics of planetary bodies (e.g., the Moon, Mars and asteroids) is, therefore, crucial for understanding the history of rocky bodies and planning exploration, mining, colonisation, and (for small planetary bodies, i.e., asteroids and comets) deflection. Humans cannot construct and build anything without understanding the rock mechanics characteristics of planets. Planetary Rock Mechanics can be a new subdiscipline of rock mechanics and engineering. This new discipline will be an enabler to achieving challenging space engineering operations.

Prof Omer Aydan
Emeritus Professor
University of the Ryukyus

Some attempts to infer mechanical properties of rocks and discontinuities in Mars and Some Comets

9:20 AM - 9:40 AM


Ömer Aydan obtained his BSc degree in Mining Engineering from Istanbul Technical University, Turkey, in 1979 and MSc degree in Rock Mechanics and Excavation Engineering from University of Newcastle Upon Tyne in 1982, and his PhD in Rock Mechanics from Nagoya University, Japan, in 1989. Aydan worked at Nagoya University as a research associate (1987-1991), and at the Department of Marine Civil Engineering at Tokai University, first as Assistant Professor (1991-1993), then as Associate Professor (1993-2001), and finally as Professor (2001-2010). Aydan then became Professor of the Institute of Oceanic Research and Development at Tokai University, and he moved to The university of the Ryukyus, Department of Civil Engineering and Architecture, Nishihara, Okinawa, Japan in November, 2013 and retired at the end of March 2020. He is currently Emeritus Professor at the University of Ryukyus, Nishihara, Okinawa, Japan.

Exploring the ancient terrains on Mars: What will they tell us about the early formation of the solar system

10:20 AM - 10:40 AM


Bob Anderson received his Bachelor of Science Degree from Old Dominion University in Norfolk, Virginia in Geology in 1979. In 1985, he received a Master of Science from Old Dominion University in geology with emphasis on structural geology and mapping tectonic features surrounding the Tharsis region of Mars. In 1995, he received a Doctor of Philosophy from the University of Pittsburgh in geology with emphasis on visible and near-infrared remote sensing. He has been at JPL for 25 years. His current research is centered on unraveling the geologic history of Mars focusing on the tectonic and paleohydrologic evolution of the Tharsis region and understanding the geomechanical properties of planetary regolith. He recently contributed to the successful Mars Science Laboratory Sample Acquisition/Sample Handling Subsystem. Bob was the past chair of the Planetary Science Division of the Geological Society of America.
