Symposium 1

Granular Materials in Space Exploration

Co-Chairs: Philip Metzger, Ph.D., University of Central Florida, Orlando, FL; and Juan Agui, Ph.D., NASA Glenn Research Center, Cleveland, OH

This symposium will focus on the science and engineering of granular materials in space exploration. When we visit a planetary body, we land on granular materials, drive on them, dig in them, extract resources from them, build with them, and study them for science. Because granular materials can rearrange on a mesoscopic scale, their emergent behaviors are difficult to predict and are the subject of intensive research by physicists, engineers, geologists, and other disciplines. Research includes experiments, computer modeling, and collection of data from planetary missions. Technologies are being developed to study granular materials on the Moon, Mars, asteroids, and beyond. Sessions in this symposium will focus on lunar regolith and dust, asteroid regolith, soil mechanics, granular flow, rocket exhaust interactions with regolith, and anything that requires or supports our understanding of granular materials in space.
